Paxlovid is a winner, but lifestyle changes are essential to mitigate Covid risk.

This discussion was originally posted before PAXLOVID WAS AVAILABLE. The title was originally Lifestyle More Effective than Drugs.

But now we have Paxlovid. Paxlovid is very effective in reducing morbidity and mortality associated with Covid-19 infection but also appears to reduce risk of Long Covid. Standard dosing: PAXLOVID two 150-mg tablets of nirmatrelvir, one 100-mg tablet of ritonavir twice daily for 5 days.

Dose adjustments are necessary for certain medical conditions and there are many drug interactions that should be considered. But do not let that discourage you from asking your provider to prescribe this drug for an acute Covid infection. This is a truly effective drug. It decreases morbidity and mortality as well as risk for Long Covid.

The results of a randomized placebo controlled clinical trial in high risk individuals has been published in the NEJM. The study was done just when Omicron hit. The study demonstrated an 89% reduction of hospitalizations and deaths by day 28 (absolute reduction of 6.2/100) with ZERO deaths in the Paxlovid group (7 in the placebo group). Paxlovid also had LESS side effects than placebo.

Another study from Israel demonstrated equally impressive results as shown here.

In addition, a study from the VA has looked at longer term effects (pre-print publication, still waiting for peer review.)

The study included 9000 Paxlovid patients treated within 5 days of symptom onset during the Omicron and subvariant waves and compared the treated patients with approximately 47,000 matched controls.

There was a 26% reduction in Long Covid.

Here is a breakdown of the Long Covid Symptoms

The VA study also showed a 48% reduction of death and 30% reduction in hospitalization after the acute phase (acute phase = first 30 days) as demonstrated here.

Many drug intervention trials for treating COVID-19 early in the pandemic have been disappointing. No studies have shown benefit for hydroxychloroquine, with or without azithromycin. This topic has been covered in previous posts. Remdesivir was FDA approved based upon one study that showed reduction in duration of symptoms. The mortality rate with Remdesivir, however, did not demonstrate a statistically significant difference when compared to “usual care”. https://www.niaid.nih.gov/news-events/nih-clinical-trial-shows-remdesivir-accelerates-recovery-advanced-covid-19

Another study published in Lancet failed to show any clinical benefit from Remdesivir.

“No statistically significant benefits were observed for remdesivir treatment beyond those of standard of care treatment. Our trial did not attain the predetermined sample size because the outbreak of COVID-19 was brought under control in China. Future studies of remdesivir, including earlier treatment in patients with COVID-19 and higher-dose regimens or in combination with other antivirals or SARS-CoV-2 neutralising antibodies in those with severe COVID-19 are needed to better understand its potential effectiveness.”

https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)31022-9/fulltext

Likewise well designed studies of Ivermectin have shown no clinical benefit.

Monoclonal antibodies effective against early variants are no longer effective against the newer variants. So in terms of drug therapies for acute Covid infections we have Paxlovid for out patient care and dexamethasone for critically ill patients.

But we do know that certain underlying conditions such as obesity, diabetes, pre-diabetes (insulin resistance) and hypertension significantly increase risk of DEATH AND COMPLICATIONS with COVID-19. Since there are lifestyle interventions that can quickly and effectively mitigate these problems (diet, exercise, sleep, stress reduction….) now would seem like a good time to take our epidemics of obesity and diabetes in hand with aggressive lifestyle interventions to decrease the mortality rate of COVID-19 infection.

Such measures do not require expensive drugs or expensive drug trials, they simply require knowledge, guidelines and the will to implement change in our daily habits. Yet there has been little discussion about this in the media or on the part of public health officials.

Lets look at obesity in the US.

From 1999–2000 through 2017–2018, the age-adjusted prevalence of obesity increased from

30.5% to 42.4%, and the prevalence of severe obesity increased from 4.7% to 9.2%.

Percent of adults aged 20 and over with obesity: 39.8% (2015-2016)
Percent of adults aged 20 and over with overweight, including obesity: 71.6% (2015-2016)

The most effective tool for addressing obesity and diabetes is a very low carbohydrate diet.

Effects of the Low Carbohydrate, High Fat Diet on Glycemic Control and Body Weight in Patients With Type 2 Diabetes: Experience From a Community-Based Cohort

https://pubmed.ncbi.nlm.nih.gov/32193200/

This study was a done in a community-based program, not an academic practice setting. That is significant since it demonstrates feasibility outside of academic centers with standard community resources. The results of this study confirmed the results of many previous studies done in academic settings including better blood sugar control, reduction or elimination of diabetic medications, and significant weight loss.

“All patients following the LCHF diet who initially took
insulin had either a reduction or discontinuation of
this therapy by their healthcare provider when clinically
indicated, compared with less than a quarter of
those receiving usual care.“

In another study done in Italy, significant weight reduction (7 kg), waistline reduction (7 cm.), fat mass reduction (3.8%) and systolic blood pressure reduction (10.5 mmHg) were achieved in 3 months with a Very Low Carbohydrate diet.

Middle and Long-Term Impact of a Very Low-Carbohydrate Ketogenic Diet on Cardiometabolic Factors: A Multi-Center, Cross-Sectional, Clinical Study (https://pubmed.ncbi.nlm.nih.gov/25986079/

Nina Teicholz had an opinion piece published in the Wall Street Journal on May 30, discussing the USDA dietary guidelines that have largely ignored a massive body of evidence supporting a Very Low Carbohydrate Diet for obesity and diabetes. She cites many studies that have been ignored by the USDA dietary guidelines committee. Here is here opening statement.

“Americans with obesity, diabetes, heart disease and other diet-related diseases are about three times more likely to suffer worsened outcomes from Covid-19, including death. Had we flattened the still-rising curves of these conditions, it’s quite possible that our fight against the virus would today look very different.”

You can read the full article here:

https://www.wsj.com/articles/a-low-carb-strategy-for-fighting-the-pandemics-toll-11590811260

But think about that simple statement, THREE TIMES MORE LIKELY TO SUFFER WORSENED OUTCOMES FROM COVID-19. Yet these conditions are highly responsive to lifestyle interventions that not only mitigate obesity, insulin resistance and high blood pressure, but also enhance immune function.

COVID 19: Link to Vitamin D status. Should doctors prescribe sunshine?

3 Replies

Preliminary (not yet peer reviewed) data on mortality rates with COVID-19 infection from Indonesia show a dramatic increase in death rates associated with low vitamin D status.

Relative Risk of DEATH Corrected for age, sex, and co-morbidities	Vitamin D level (ng/ml)
10.1	<20
7.6	21-29
1	>= 30

Prabowo, Patterns of COVID 19 Mortality and Vitamin D, Indonesian Study, Ap 26, 2020 BMJ

This study was a retrospective cohort study of 780 cases of laboratory confirmed COVID-19 in Indonesia. Age, sex, co-morbidity (hypertension, diabetes, obesity etc.) and Vitamin D levels were extracted from medical records. The differences between patients with various levels of vitamin D were statistically significant and CLINICALLY SIGNIFICANT.

If there were a drug that reduced mortality by 10 fold it would be a best-seller/blockbuster drug.

“When controlling for age, sex, and comorbidity, Vitamin D status is strongly associated with COVID-19 mortality outcome of cases.”

Association does not equal causation but this profound degree of association warrants further consideration. Is it possible that Vitamin D insufficiency could cause such a profound influence on death rates with a viral infection?

Before we answer that question let’s look at some other data. Risk of death with COVID-19 dramatically changes with latitude (sunlight exposure reflecting Vitamin D making capability):

Latitudes	Hospitalizations COVID-19	Deaths COVID-19
Northern	22%	5.2%
Equator	9.5%	3.1%
Southern	8.7%	0.7%

You can read about this data here.

The authors state:

“Although it is more likely that any protective effect of vitamin D against
Covid19 is related to suppression of cytokine response and reduced severity/risk for ARDS, there is also evidence from a meta-analysis that regular oral vitamin D2/D3 intake (in doses up to 2000 IU/d without additional bolus), is safe and protective against acute respiratory tract infection, especially in subjects with vitamin D deficiency. It therefore seems plausible that Vitamin D prophylaxis (without over-dosing) may contribute to reducing the severity of illness caused by SARS-CoV-2, particularly in settings where hypovitaminosis D is frequent. This will include people currently living in Northern countries and those with underlying gastroenterological conditions where vitamin D deficiency is more prevalent. This may become even more important with absence of sunlight exposure as a consequence of “shut-down” measures to control the spread of Covid19. For this to be effectively implemented will require worldwide government guidelines, and further studies looking at possible impacts of vitamin D deficiency on Covid-19 outcomes are urgently needed.”

Plenty of references are provided for their discussion so I encourage you to not only read the publication but further explore their references.

The importance of Vitamin D for proper immune function has been well studied and known for a long time.

“Vitamin D metabolizing enzymes and vitamin D receptors are present in many cell types including various immune cells such as antigen-presenting-cells, T cells, B cells and monocytes. In vitro data show that, in addition to modulating innate immune cells, vitamin D also promotes a more tolerogenic immunological status. In vivo data from animals and from human vitamin D supplementation studies have shown beneficial effects of vitamin D on immune function, in particular in the context of autoimmunity”

“Especially in the field of human immunology, the extra-renal synthesis of the active metabolite calcitriol—1,25(OH)2D—by immune cells and peripheral tissues has been proposed to have immunomodulatory properties similar to locally active cytokines”

Now consider this startling fact. At the turn of the century (2001-2004) 70% of the US population over age 12 had 25 Hydroxy-Vitamin D levels LESS THAN 30 ng/ml.

And the situation has not improved since that study. In the chart above that places 70% of the US population in the groups with 7.6 to 10.1 times increased risk of death from COVID 19 compared with those having “normal” levels (>30 ng/ml).

Conclusions

“National data demonstrate a marked decrease in serum 25(OH)D levels from the 1988–1994 to the 2001–2004 NHANES data collections. Racial/ethnic differences have persisted and may have important implications for known health disparities. Current recommendations for vitamin D supplementation are inadequate to address the growing epidemic of vitamin D insufficiency.”

Multiple studies on COVID-19 have shown higher mortality rates amongst blacks. Although this is likely related to many socio-economic and nutritional factors, blacks have consistently shown significantly lower Vitamin D levels in the US compared with other ethnic/racial groups.

During the 2009 Viral Pandemic, death rates were observed to increase with distance from the equator, similar to the COVID-19 observations.

Death rates from COVID-19 in ITALY, where Vitamin D status is much lower compared to the rest of Europe, have been higher than other countries in Europe.

And a large report on Vitamin D status in Europe and the Middle East states:

“A low vitamin D status was also associated with increased mortality risks as extensively reviewed” with references (3, 27, 206, 209).

A brilliant video podcast on the relationship between Vitamin D and COVID-19 can be viewed here.

And if you wish to further explore the health effects of Vitamin D you can watch this:

Insufficient Vitamin D levels are associated with almost every risk factor for Morbidity and Mortality with COVID-19 including Diabetes, Insulin Resistance, Obesity, Hypertension and Cardiovascular Disease.

Many of the concerns covered in Ivor Cummin’s podcast above have been covered in previous posts here including the importance of Vitamin K2 and other fat soluble vitamins, the importance of SUNSHINE for general health and immune function, and the importance of a nutrient dense whole food diet rich in wild seafood and grass fed animal sources of protein. Almost every cell in the body has receptors for Vitamin D. The most beneficial sources of Vitamin D include sunshine and food sources. Supplementation is often necessary to achieve levels above 30 ng/ml, especially during the winter months (when respiratory viruses strike) and increase with distance from the equator.

The deleterious effects of inadequate Vitamin D cannot be overstated. The consequences below only address the effects of Vitamin D insufficiency on bone health but the causes and prevention are important to understand. Vitamin D deficiency = Immune Deficiency and is likely strongly and causally related to increased risk of death with COVID-19.

Vit D status, sources.jpeg

Here is an image that links Vitamin D deficiency to Diabetes, inflammation and oxidative stress:

inflamation, PTH, Oxidative stress, calcium, IR, DM2.png

And here is a good description of the consequences of inadequate Vitamin D.

vitamin-d-deficiency-causes and consequences.png

So what do you think? Is it possible that Vitamin D insufficiency could cause such a profound influence on death rates with a viral infection? Lets look a little closer.

The Public Health system in UK has been concerned about Vitamin D deficiency:

vitamin-d-deficiency-symptoms UK Public Health.jpg

And once again here is how inadequate Vitamin D interacts with the co-morbidities that are unequivocally associated with increased death rates associated with COVID-19 infection.

Vit D and inflammation.jpg

PTH is parathyroid hormone. The RAAS above refers to the renin-angiotensin system hypertension effects mediated through the kidney. The chronic inflammation associated with inadequate Vitamin D leads to atherosclerosis and cardiovascular events, diabetes, insulin resistance, metabolic syndrome which all have positive feedback effects on each other. They all increase risk of death with COVID-19.

Again I ask, what do you think? Is it possible that Vitamin D insufficiency could cause such a profound influence on death rates with a viral infection?

(The thing speaks for itself)

RX from the doctor could read:

Sunbath for 15 minutes daily between 1100 AM and 1 PM (wear a hat, sunglasses, bathing suit optional depending on circumstances and privacy)

Eat fatty fish frequently.

Get your 25 hydroxy-vitamin D levels checked, if < 30 ng/ml increase the above.

Supplement in the winter.

Ketogenic Diet, Keto-Medicine

Leave a reply

I have spent a few days watching lectures from various low-carb-healthy-fat meetings. There is an impressive amount of solid clinical data to support Very Low Carb (with healthy fat) diets to treat obesity, insulin resistance, diabetes, pre-diabetes, metabolic syndrome, and seizure disorders. Eric Westman MD, author, Associate Professor of Medicine, Past Chairman of the Obesity Medicine Association, and director of Duke University Lifestyle Medical Clinic gave an impassioned and authoritative talk on the success of LCHF in treating all of these disorders here.

Dr. Steven Phinney, Professor Emeritus UC Davis and presently Chief Medical Officer for VIRTA has given numerous talks on the beneficial effects of a ketogenic diet. He and Jeff Volek Ph.D. have done research for decades on the physiology of low carbohydrate diets. They elucidated the changes that occur in high level athletes as they adapt to burning fat as their major fuel source during and after a period of “fat adaptation”. It turns out that endurance athletes, after a period of 1 to 3 months of adaptation to a low carb-high fat diet (variable from person to person) perform at equal or higher levels as compared to their performance when previously on a high carbohydrate diet. In fact, because lean athletes have much greater energy stored in fat as compared to glycogen (carbohydrate) they can go for many hours longer than an athlete who is dependent on carbohydrate metabolism (not fat adapted). Glycogen is the starch source of energy that humans store in the liver (100 grams) and in muscle (400 grams). Compared to glycogen, fat stores in lean individuals, including buff athletes, can provide more than 10 times the amount of energy. Endurance athletes who are keto-adapted (fat burners) can ride a bike all day or run an ultra-marathon (100 miles) without taking in any energy source. (They must of course replace fluid and electrolytes). Whereas athletes who have followed a traditional high carb diet must start consuming calories after about 3 hours of moderate-high intensity exercise. Doctors Phinney and Volek have done clinical research on humans with obesity, pre-diabetes and diabetes and they have demonstrated superior results when compared to any other dietary approach.

You can learn about their work here:

And here:

So what is this all about? If carbohydrates are restricted to very low levels and instead we consume (healthy) fat as our major source of energy with moderate amounts of protein, then the human body starts to burn fat. This process results in the production of ketones (in the liver) which serve not only as a source of energy but also act as “signaling” molecules that turn on beneficial genes that fight inflammation and turn off genes that produce inflammation. When a well formulated ketogenic diet is followed under medical supervision, diabetics can often get off most or all of their diabetes medications within weeks to months as they lose weight. Improvements are seen quickly in blood pressure, fasting blood sugar, liver function tests, insulin sensitivity, inflammatory markers, subjective energy levels, mental clarity and mood. Triglycerides are reduced, HDL increases, and improvements are seen in the “atherogenic profile” with reductions in small dense LDL particles with a shift to large buoyant LDL particles. On a ketogenic diet humans spontaneously consume lower caloric intake because fat and protein are more satiating compared to carbohydrate. Circulating saturated fat in the blood DECREASES on a keto-genic diet. Refined carbohydrates and sugar (so prevalent in processed foods) produce increased circulating fat in the blood and increased fat storage throughout the body, often leading to fatty liver disease and the long list of chronic diseases caused by and associated with insulin resistance.

A ketogenic diet is also part of Dr. Dale Bredesen’s effective treatment program for early dementia (ReCoDe-Reversal of Cognitive Decline). I have discussed Dr. Bredesen’s approach before. Here is one of his discussions.

You can read Dr. Bredesen’s report of 100 patients who have reversed cognitive decline using a ketogenic diet as PART of the ReCoDe program here.

So what are the healthy fats in a low carb high fat diet?

They include fats found in whole foods such as nuts and avocados, pasture raised animals free of hormones and antibiotics, free range poultry and eggs, wild fish and seafood (avoiding large fish that have high mercury levels), extra virgin olive oil, avocado oil, butter from pastured grass-fed animals, and coconut oil. (yes butter is included despite that fact that strict paleo excludes dairy)

You should avoid all of the processed/refined oils that come from seeds, grains and legumes including soy oil, corn oil, cottonseed oil, canola oil, safflower oil, sunflower oil, sesame oil. You can learn why these (misnamed) “vegetable oils” are dangerous and how they were marketed to an unwitting public with the help and support of faulty science by listening to Nina Teicholz here:

There are many great lectures about the low-carb-high-fat ketogenic diet in addressing obesity, insulin resistance, pre-diabetes, metabolic syndrome, diabetes, seizures and more. Go to youtube and search “keto diet”, “low carb high fat”.

Exercise as Medicine

3 Replies

For many chronic health problems, regular exercise is more effective than any drug.

Exercise as Medicine is a major movement at John’s Hopkins School of Medicine.

You can visit this website for links to many topics on the benefits of exercise.

You can find the top 10 things you need to know about exercise here. They include the following evidence based recommendations from the Physical Activity Guidelines for Americans.

any amount of physical activity has some health benefits. Americans can benefit from small amounts of moderate-to-vigorous physical activity throughout the day.

The benefits of exercise are cumulative, walk 10 minutes 3 times per day and you get the same benefit as a 30 minute walk. Walk 5 minutes 6 times and the benefit equals that of 30 minutes continuous walking. So you can break up your exercise in little pieces throughout the day. No requirement for a specific long period devoted to exercise.

New evidence shows that physical activity has immediate health benefits. For example, physical activity can reduce anxiety and blood pressure and improve quality of sleep and insulin sensitivity.

Exercise improves cognition, decreases cancer risk, decreases risk of depression, hypertension, diabetes, stroke and heart disease. It lowers risk of falls and injuries from falls. It decreases pain and helps a variety of conditions. Exercise reduces all cause mortality (death rates from all causes)

Here are some direct quotes from the second edition of the Physical Activity Guidelines.

For youth, physical activity can help improve cognition,* bone health, fitness, and heart health. It can also reduce the risk of depression.
For adults, physical activity helps prevent 8 types of cancer (bladder,* breast, colon, endometrium,* esophagus,* kidney,* stomach,* and lung*); reduces the risk of dementia* (includingAlzheimer’s disease*), all-cause mortality, heart disease, stroke, high blood pressure, type 2 diabetes, and depression; and improves bone health, physical function, and quality of life.
For older adults, physical activity also lowers the risk of falls and injuries from falls.*
For pregnant women, physical activity reduces the risk of postpartum depression.*
New evidence shows that physical activity can help manage more health conditions that Americans already have. For example, physical activity can decrease pain for those with osteoarthritis, reduce disease progression for hypertension and type 2 diabetes, reduce symptoms of anxiety and depression, and improve cognition for those with dementia, multiple sclerosis, ADHD, and Parkinson’s disease.

You can choose from a variety of TEDtalks on exercise here.

I particularly enjoyed my friend Darryl Edwards talk here.

So sleep well, exercise often, eat clean, filter your water, avoid environmental toxins, get plenty of sunshine, and most important of all, stay connected with friends and family.

Sleep! You can’t live without it.

Circadian rhythm refers to the cycling of hormones according to the time of day. Every hormone cycles with daylight and darkness, each in it’s own way. Our brain has a master clock, called the circadian clock, controlled by specialized cells deep in the brain. There is a direct connection from our retina (in the back of the eyes) to the circadian clock in the brain. Blue light (part of the normal outdoor spectrum of light) stimulates very specific receptor cells in the retina which in turn communicates directly with the circadian clock telling the brain whether it is day or night. To synchronize our hormones and achieve restorative sleep, we must get outdoor light exposure to our eyes (without sunglasses, early in the day) and limit light exposure in the evening.

Artificial light, especially from cell phones and other devices that emit intense blue light, shift work, late night social activity, poor eating habits, sedentary lifestyle and at the opposite extreme, late evening workouts, can all disrupt our circadian rhythm preventing adequate restorative sleep. A rare genetic illness called fatal insomnia that strikes adults at middle age prevents sleep and results in death within a few months, highlighting the importance of sleep. Sleep deprivation can kill a human quicker than starvation! Adequate amounts of deep non-REM sleep are required for tissue regeneration, healing, DNA repair and immune function. REM sleep with dreaming provides great benefit by organizing our memory, discharging the emotional content of traumatic events, and facilitating creative brain activity. One night of short-sleep produces a state of inattention and slow reflexes as dangerous as driving under the influence of alcohol intoxication. Chronic short sleep and disrupted circadian rhythm results in increased risk of depression, cancer, hypertension, diabetes, dementia, obesity, metabolic syndrome, insulin resistance, heart attack and stroke, to name a few. Sleep interruption immediately halts weight loss during a calorie restricted diet (likely the result of hormonal disruption). So getting an adequate amount of restorative sleep every night is essential to good health. Here a few tips to help achieve a good night’s sleep each and every night.

GET OUTDOOR LIGHT EXPOSURE ON YOUR EYES WITHOUT SUNGLASSES EVERY DAY, EARLY IN THE DAY. This helps set your biologic/circadian clock. Even on a cloudy day, outdoor light is much stronger and natural than indoor light. It is essential for setting your biologic/circadian clock. If you cannot get outside, stand or sit in front of a large window for 20-30 minutes in the morning, looking outside. Take a lunch break outside without sunglasses. Wear a shade hat instead of sunglasses. Your brain needs to experience natural outdoor light during the day.
Avoid bright light in the evening, especially the light from TV, computer screens, cell phones, which all emit intense blue light and trick your brain into thinking it is daytime. Wear blue light blocking glasses/goggles for 2-3 hours before bed. (Amber tinted glasses which block blue light can be purchased on-line and can be worn over reading glasses) There is also software available that will decrease the blue light intensity of computer screens and cell phones in the evening.
Practice time restricted eating. Limit all eating to an eight hour period, thus providing for an over-night fast of 16 hours. If that does not seem possible try to limit eating to a 10-hour period which provides a 14-hour overnight fast. This improves sleep, circadian rhythm, blood pressure, blood sugar and reduces stress hormones. NO SNACKS BETWEEN MEALS. NO FOOD FOR 2 HOURS BEFORE BED. For every hour decrease in eating time period from 12 hours to 8 hours you get health benefit.
Eat an anti-inflammatory diet.
If you snore, are overweight/obese, fall asleep during the day, or do not feel refreshed in the morning ask your doctor to order a sleep study. Obstructive Sleep Apnea makes restorative sleep impossible and increases risk of heart attack, stroke and most chronic diseases.
Avoid alcohol altogether and avoid caffeine after late morning. Alcohol in the evening may help you fall asleep but it results in a withdrawal from alcohol during the night. This disrupts normal sleep patterns.
Sleep in a cold, dark, quiet room. Use black-out curtains, no night lights, no phone charger lights, no lights of any kind should be on in the room. Any amount of light in the room impairs the production of melatonin which facilitates sleep onset.
Have a wind–down time every evening. Develop habits of non-stressful activities, soft music, dim light, casual conversation, enjoyable reading. Do not spend evening time dealing with finances, conflict, or emotional activity.
Try a magnesium supplement before bedtime. Magnesium glycinate, magnesium citrate, magnesium gluconate, are absorbed much better than cheaper supplements such as magnesium oxide. Magnesium L-Threonate is expensive, but it crosses the blood brain barrier into the brain with the greatest brain penetration of all magnesium supplements.
Manage stress with yoga, meditation, regular exercise (but no intense exercise in the evening.) Perform most of your exercise outdoors in a green space. This provides much more health benefit than the equivalent exercise indoors.
Regular contact with supportive family and friends is essential to health and reduces stress. The greatest predictor of health vs disease is the amount of social connectedness an individual experiences.
Establish regular wake-up times and go-to-bed times. Regular sleep habits are essential. If you must rely on alarm clocks you do not have good sleep habits.

A few words about alcohol, caffeine and sleeping pills.

A drink or two in the evening may help you relax but it disrupts your sleep by causing a mild episode of alcohol withdrawal as your liver metabolizes the alcohol and your blood levels drop. Even this slight degree of alcohol withdrawal will impair a good night’s sleep.

Caffeine impairs sleep by blocking adenosine receptors in the brain. Adenosine is the neurotransmitter that increases gradually during the day creating a sate referred to as sleep pressure. Some people metabolize caffeine quickly, others slowly. The slower you metabolize caffeine the longer it takes to clear it from your adenosine receptors. Without adequate sleep pressure (adenosine receptors filled with adenosine in the brain) you cannot fall asleep. Many sleep experts recommend complete abstinence from caffeine and suggest that if you need caffeine to get started in the morning you are regularly sleep deprived.

Sleeping pills of all kinds interfere with normal sleep architecture. While they facilitate falling asleep, they impair your ability to achieve deep restorative stages of sleep and can produce many undesirable side effects including addiction, withdrawal symptoms, sleep walking, sleep driving, worsening of asthma and COPD, constipation, diarrhea, daytime drowsiness, burning and tingling sensations, unusual dreams, weakness, heartburn, etc…. Most importantly they all interfere with cycling through the various stages of sleep in a normal, restorative pattern!

If you want to explore these concepts in depth here are two excellent books that discuss sleep and circadian rhythm.

Western Diet (high sugar, refined carbs, unhealthy fats) alters genes and causes inflammation

Leave a reply

New study (in mice) shows fast food makes the immune system more aggressive in a detrimental way.

Major points:

The immune system reacts similarly to a high sugar, high (unhealthy) fat and high calorie diet as to a bacterial infection.
Unhealthy food seems to make the body’s defenses (innate immune system) more aggressive in the long term. Even long after switching to a healthy diet, inflammation towards innate immune stimulation is more pronounced.
These changes may be involved in the development of arteriosclerosis and diabetes.
These changes are due to alterations in gene transcription (up-regulation of genes associated with inflammation)
This up regulation of pro-inflammatory genes persists even after converting to a healthier diet.

Anti-inflammatory diet, are 9 servings of vegetables per day possible?

Leave a reply

I often recommend a specific diet to decrease inflammation, decrease pain, and improve healing of tissue. I have been asked by patients to post this nutritional plan on my website so here it is (see below). In addition to this post, I will place the diet on a separate page along with recipes for vegetable soup and bone broth.

The recipes (vegetable soup and bone broth) meet the anti-inflammatory diet guidelines and also follow the more restrictive “Autoimmune Protocol”. This nutritional approach provides an array of micro nutrients that fight inflammation, support tissue repair, decrease the risk of chronic disease, and help maintain a healthy gut flora (good bacteria in the intestines).

When I recommend 9 servings per day of vegetables patients often tell me it is impossible to achieve. But it is not impossible, nor is it impractical. Every Sunday afternoon I make a large pot of vegetable soup that will keep all week in the refrigerator. I bring generous servings to work every day for breakfast, brunch, and/or lunch and add some meat or seafood prepared the evening before (left-overs) on the side. The key to eating 9 servings per day is to have a variety of vegetables at every meal. The vegetable soup makes that goal not just achievable but convenient.

The anti-inflammatory diet described below provides ample fiber to feed your healthy gut bacteria and avoids the sugar and refined starches that can produce gut dysbiosis (unhealthy balance of bacteria in the intestines). Vegetables provide five times the amount of fiber per calorie compared to grains. You do not need to eat bread or cereal to get fiber.

So here is the anti-inflammatory diet. it is consistent with the Mediterranean diet as well as an Ancestral-Paleo diet.

Caution: if you have diabetes and are taking medications, this diet reduces carbohydrates and eliminates added sugar so adjustments in diabetes medications are necessary to avoid potentially dangerous low blood sugars. So consult your physician or primary care practitioner.

Don’t eat plastic foam in your food, another reason to avoid bread, bakery and flour foods

Leave a reply

I recently came across an article at EWG.org, Nearly 500 ways to make a yoga mat sandwich | EWG

“If you’ve planked on a yoga mat, slipped on flip-flops, extracted a cell phone from protective padding or lined an attic with foam insulation, chances are you’ve had a brush with an industrial chemical called azodicarbonamide , nicknamed ADA. In the plastics industry , ADA is the “chemical foaming agent ” of choice. It is mixed into polymer plastic gel to generate tiny gas bubbles, something like champagne for plastics. The results are materials that are strong, light, spongy and malleable. “

Turns out, ADA is in nearly five hundred foods including breads, tortillas, bagels, pizza, hamburger buns, various pastries, hot dog rolls, sandwich buns, Italian bread, bread sticks, dinner rolls, croutons, english muffins, focaccia, wheat bread. Not all food producers include ADA in their products but many do, including fast food chains.

“Over the years, health activists concerned about synthetic chemicals in food have attacked the widespread use of ADA, but it did not attract nationwide headlines until Hari of Food Babe circulated a petition demanding that Subway, among the nation’s biggest fast-food outlets, stop using the chemical in its loaves. Subway responded [http://www.subway.com/subwayroot/about_us/PR_Docs/QualityBread.pdf] that ADA was safe, but even so, it had quietly been seeking a substitute over the past year. The company pointed out that ADA is “found in the breads of most chains such as Starbuck’s, Wendy’s, McDonald’s, Arby’s, Burger King, and Dunkin Donuts.” Those other fast food giants joined Subway on the defensive.”

So head on over to the environmental working group website by clicking the link above and educate yourself. The reasons to avoid flour foods continue to mount, glyphosate (roundup), ADA, obesity, auto-immune disease, metabolic syndrome, diabetes, heart attack, stroke, endotoxemia…..

Obesity Epidemic Requires a Paradigm Shift

1 Reply

The obesity epidemic requires a paradigm shift. Several medical myths stand in the way of taking the most effective steps to safely help patients lose weight. The most important myth relates to saturated fat. Saturated fat consumption does not contribute to cardiovascular disease. This must be understood and accepted by the medical community so that sound advice can be given.

A meta-analysis of prospective epidemiologic studies showed that there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of CHD or CVD.( Am J Clin Nutr. 2010 Mar;91(3):497-9. )

In fact, as early as 2004, Mozaffarian et. al. investigated the influence of diet on atherosclerotic progression in postmenopausal women with quantitative angiography and found that:

In multivariate analyses, a higher saturated fat intake was associated with a smaller decline in mean minimal coronary diameter (P = 0.001) and less progression of coronary stenosis (P = 0.002) during follow-up. (Am J Clin Nutr. 2004 Nov;80(5):1175-84)

In addition, they further found that:

Carbohydrate intake was positively associated with atherosclerotic progression (P = 0.001), particularly when the glycemic index was high.

Polyunsaturated fat intake was positively associated with progression when replacing other fats (P = 0.04)

These findings should come as no surprise given the basic science of atherosclerosis. Oxidized and glycated LDL stimulate macrophages to become foam cells initiating the creation of plaque. Cellular receptors that allow macrophages to ingest oxidized LDL are specific for oxidized LDL. These receptors do not recognize normal LDL to a significant degree.

Holovet et. al. studied the ability of oxidized LDL versus the Global Risk Factor Assessment Score (GRAS) to detect coronary artery disease. GRAS identified coronary artery disease 49% of the time, while oxidized LDL was correct 82% of the time.

In a large prospective study, Meisinger et al found that plasma oxidized LDL was the strongest predictor of CHD events when compared to conventional lipoprotein risk assessment and other risk factors for CHD.

Polyunsaturated fats are easily oxidized, saturated fats are not. It is the polyunsaturated fatty acids (PUFA) in the membrane of LDL particles that become oxidized and then initiate the cascade of inflammatory events leading to atherosclerosis. The major source of these PUFA in the American diet are “vegetable oils” (corn oil, soy oil etc.) rich in the omega-6 PUFA, linoleic acid.

So why is this important to understand relative to the obesity epidemic? Because the most effective weight loss “diet” is arguably a low carbohydrate/high fat (LCHF) diet. This approach does not require calorie counting. This approach has been demonstrated to spontaneously reduce caloric intake whereas low fat diets require calorie counting and result in persistent hunger.

When compared to low fat calorie restricted diets the LCHF approach has been equal or superior with respect to weight loss, insulin sensitivity, blood pressure reduction, and lipid profiles whenever these parameters have been measured.

But LCHF has not been embraced by the medical community due to the perceived dangers of saturated fat consumption and a low-fat ideology that lacks legitimate scientific evidence.

Once we dispel the mythology of saturated fat, the safety and efficacy of LCHF will be more readily accepted by physicians, the media and the lay public.

The nutritional villains in our society are highly refined and easily oxidized “vegetable oils” filled with pro-inflammatory omega-6 PUFA (linoleic acid), added sugar (especially HFCS) so prevalent in most processed foods and soft drinks, and the nutrient poor wasted calories of processed flour foods. These three culprits are responsible for our epidemics of obesity, insulin resistance and metabolic syndrome. These three conspire together to generate fatty liver disease, atherosclerotic plaque, and chronic inflammation.

When a LCHF approach is combined with eating only fresh whole foods and avoiding added sugar, refined flour, and unhealthy “vegetable oils”, we have the perfect recipe for our obesity epidemic.

The following references provide examples of studies that have demonstrated the efficacy, safety and usual superiority of the LCHF approach to weight loss.

Fred Kummerow, PhD, fought the battle against Trans Fats for over 50 years.

Leave a reply

Professor Fred Kummerow passed away on May 31 at his home in Urbana, Ill at age 102. He ate butter, red meat and eggs cooked in butter, along with plenty of fruits and vegetables. He avoided margarine, french fries and other fried foods, along with cookies, cake and crackers which contained artificial trans-fats. He conducted research in his nutrition science laboratory at the University of Illinois up until his death. he authored the book Cholesterol Won’t Kill You, But Trans Fat Could: Separating Scientific Fact from Nutritional Fiction in What You Eat

Fred warned the American public and scientists in the 1950s about the dangers of artificial man-made trans fats. His research was largely ignored and criticized by the food industry and by scientists who were funded by the food industry for decades. Despite mounting evidence in both animals and humans that artificial trans fats dramatically increased the risk of heart attacks, strokes, peripheral vascular disease, diabetes, obesity, and probably several forms of cancer, the FDA ignored his pleas to address the issue. In 2009 Professor Kummerow filed a petition with the FDA to ban the use of trans fats. Although federal law required that the FDA respond within 180 days to such a petition, the FDA remained silent. In 2013, approaching the age of 99, Professor Kummerow sued the FDA. Two years latter in 2015 the FDA declared that artificial trans-fats were unsafe and should be eliminated from the US food supply by 2018.

Through his lifelong work, Professor Kummerow has produced a policy change that will likely save hundreds of thousands of lives.

What are trans fats and why have they been in our food for 7 decades?

Although there are some forms of natural trans fats which are safe for consumption when consumed in whole foods, artificial trans-fats are produced by placing unsaturated fat (such as corn oil, soy oil) under high pressure and high temperature conditions and adding hydrogen in the presence of a metal catalyst. These fats were introduced to many American foods because they dramatically extend the shelf life of foods and give a pleasant mouth texture to a variety of processed foods. They remain in many foods still on the shelves today. You cannot rely on labels such as “NO TRANS FATS” OR “TRANS FAT FREE” because food companies are allowed to make this statement as long as the amount of trans fats does not exceed 0.5 grams per serving. No amount is safe!

The Institute of Medicine, on July 10, 2002 declared manufactured trans fatty acid (TFA) a serious danger to the health of our nation with a: “tolerable upper intake level of zero.” This means there is no safe level of consumption. Despite that strong statement in 2002, it has taken the efforts of an elderly professor, including a lawsuit, to bring the FDA around to finally address the issue.

But it is not over yet, you can bet that the food industry will try to delay the implementation of the ban or possibly even argue against the overwhelming science that supports such a ban.

In the meantime read labels. If any food item contains “partially hydrogenated” oil of any kind or “hydrogenated oil” of any kind it contains trans fats. These foods are typically foods you should not be eating any way because they usually also contain added sugar, refined flour and/or refined easily oxidized inflammatory “vegetable” oils. They are not whole foods and therefore should not be consumed for many reasons. But if you want to eat cake, cookies, crackers, bread, or any other processed foods, beware and read the ingredients so as to at least avoid trans-fats.

You can read about Fred Kummerow, his life and research at these sites:

Fred A. Kummerow, scientist who raised early warnings about trans fats, dies at 102 – The Washington Post

Fred A. Kummerow, an Early Opponent of Trans Fats, Dies at 102 – The New York Times

Fred Kummerow, U. of I. professor who fought against trans fats, dies at 102 – Chicago Tribune

Fred also studied the effects of a oxysterols and oxidized low-density lipoprotein (OxLDL) both of which contribute to atherosclerosis. In a 2013 publication Professor Kummerow stated

“levels of oxysterols and OxLDL increase primarily as a result of three diet or lifestyle factors: the consumption of oxysterols from commercially fried foods such as fried chicken, fish and french fries; oxidation of cholesterol in vivo driven by the consumption of excess polyunsaturated fatty acids from vegetable oils; and cigarette smoking.”

Yet the American Heart Association continues to recommend increased consumption of polyunsaturated fats from the likes of corn oil, soy oil, cottonseed and similar oils. I have discussed the problems with that advice here and here.

So the next time you avoid trans fats by reading food labels, think of Professor Kummerow who brought light to some very dark areas in the history of nutrition and food in the US.

Eat clean, live clean, and enjoy.
