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

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

Major points:

  1. The immune system reacts similarly to a high sugar, high (unhealthy) fat and high calorie diet as to a bacterial infection.
  2. 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.
  3. These changes may be involved in the development of arteriosclerosis and diabetes.
  4. These changes are due to alterations in gene transcription (up-regulation of genes associated with inflammation)
  5. This up regulation of pro-inflammatory genes persists even after converting to a healthier diet.

And here Western Diet Triggers NLRP3-Dependent Innate Immune Reprogramming: Cell

This study is an example of epigenetics, where an environmental factor (diet) alters the expression of genes. We know that regular consumption of a variety of colorful vegetables mediates many beneficial effects and part of that process involves altering the transcription of many genes related to health and our ability to defend against Oxidative Stress .

The epigenetic effect of nutrition can be transmitted to the next generation.

The epigenetic effects of diet include many aspects of health including  cancer risk.

And epigenetic changes in humans can begin  before birth in response to maternal nutrition and maternal exposure to environmental toxins .

Diet also effects the gut microbiome, which in turn affects health .

So avoid fast food and other forms of processed-refined foods. Eat a whole foods-ancestral diet that includes a variety of organic colorful vegetables and fruits, grass fed/finished meats and wild seafood. This will not only provide important micro and macro nutrients but will also turn up and turn on genes that prevent disease.

Live clean, sleep well, laugh and love.

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

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.

9 SERVINGS  OF NON-STARCHY VEGETABLES PER DAY, 3 SERVINGS FROM EACH OF THREE CATEGORIES. Organic as much as possible. (Read about the Dirty Dozen here: Dirty Dozen | EWG’s 2017 Shopper’s Guide to Pesticides in Produce )

  •  Dandelion Greens, Endive, Escarole, Kale-all kinds, Parsley, Radicchio
  • Radish leaves, Spinach, Turnip Greens, Watercress
  1. Colored vegetables, 3 cups daily:
  • GREEN: Artichoke, Asparagus, Avocado (FRUIT), Cabbage (red and green) Celery, Cucumber with skin, Okra, Olives, Peppers, Zucchini with skin
  • RED: Beets, red cabbage, red peppers, cooked tomatoes (fruit)
  • YELLOW: Carrots, Pumpkin, Squash-summer and winter, Sweet potato,
  1. SULFUR RICH VEGETABLES, 3 CUPS DAILY: Some leafy greens are also sulfur rich so there is overlap in these categories
  • Arugula, Asparagus, Bok Choy, Broccoli, Brussel sprouts, Cabbage, Cauliflower, Collard Greens, Garlic, Kale, Kohlrabi, Leeks, Mushrooms, Onions red-yellow-white, Radishes, Scallions, Shallots, Turnip Greens, Watercress.

OMEGA-3 rich fish-seafood (at least 16 ounces per week)

  • Anchovies, clams, herring, mackerel, mussels, oysters, salmon, sardines, trout, calamari (squid), saltwater fish should be wild, shellfish farmed OK, farmed trout OK.

Meat ideally grass fed and grass finished, hormone and antibiotic free.

Poultry and eggs free range, any wild game meat or poultry.

Drink only filtered water, coffee, tea, bone broth (homemade is best) and kombucha.

No grains, cereal, bread, pasta, no food made from flour, no oats, wheat, barley, corn etc.

No legumes (beans), no peanuts

No dairy except Ghee for cooking (optional)

No processed food made with added sugar or hydrogenated oils (which contain trans-fats)

No “vegetable oils” (soy oil, corn oil, etc.)

Use only extra-virgin olive oil, coconut oil, avocado oil and ghee. Limit EVOO to low heat cooking or add after food is cooked. The other oils on this list have higher smoke points.

Do not use store-bought salad dressing which usually has added sugar and inflammatory vegetable oils. Make your own salad dressing with EVOO and vinegar or lemon juice.

For more information about the AIP (Autoimmune protocol)  I suggest you visit these websites:

The Autoimmune Protocol – The Paleo Mom

The Autoimmune protocol is more restrictive than the anti-inflammatory diet and is beneficial for individuals with autoimmune disease.

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

I recently came across an article at, 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 [] 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…..

Live clean, sleep well, love and laugh.

Obesity Epidemic Requires a Paradigm Shift

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.

Weight loss, discussion by Tommy Wood MD, PhD

My friend and colleague, Dr. Tommy Wood, recently posted a terrific discussion on weight loss and the many factors to consider. You can read it here. Should Calorie Counting Be the Main Focus for Somebody Trying to Lose Weight (Body Fat)? | Nourish Balance Thrive

Tommy is the smartest physician I know. He researches a topic extensively and carefully separates bad science from good science.

If Tommy renders an opinion, you can take it to the bank.

Read the NBT post by Tommy at the link above and you will not be disappointed. Then sign up to receive short weekly e-mails with sound advice on health and nutrition.

I have discussed the importance of circadian rhythm, restorative sleep, hormonal effects of food choices, and the effects of stress. Tommy covers all of these and much more with links to scientific papers if you are interested in delving deeply into the issues. But if you just want sound advice on weight loss,  read the post and organize your life around improving your habits as he recommends.

Live clean, eat real food, spend time with friends and family, hug someone every day, engage in meaningful work, get sunshine early in the day, exercise in a green space and live in the moment.

Functional Medicine: Getting to the Root Causes of Illness, A cure for Alzheimer’s

Today I watched a great TED talk by Dr. Rangan Chaterjee discussing his own journey in the discovery and implementation of a functional medicine approach to caring for his patients. The concept of using basic science and clinical science to diagnose and treat the root causes of illness, rather than treating symptoms, has been around for more than two decades.  This approach has recently started to attract more attention, especially within the community of younger physicians who have become more dissatisfied with the frustrations of traditional allopathic medicine.

Here is the talk. Dr. Chatterjee covers lots of ground in a passionate and informative talk.

Enjoy this talk. If you would like to learn about how a functional medicine approach can CURE ALZHEIMER’S DISEASE then watch this video of Dr. Bredesen who gave this lecture at a meeting of the American College of Nutrition.

Doctor Bredesen, an acclaimed neuroscientist, researcher, and more recently a brilliant clinician, has been criticized by the academic research community for implementing a clinical research protocol that addresses more than one variable at a time! Unfortunately, medical science has been handcuffed by the drug-model of clinical research wherein only one variable (drug vs. placebo for example) is studied. But if an illness has many potential contributing root causes, changing only one variable is doomed to failure, as Dr. Bredesen explains in this lecture.

Sleep well, eat clean, get outdoors every morning to help keep your circadian rhythm and biological clock in order.
