“The promising findings coming from the cumulative research work over the last decade solidified the role of ω-3 PUFAs as a potential candidate to prevent or even treat such autoimmune diseases as type 1 diabetes, RA, SLE, MS”
“Altogether the data reported in this review show that anti-inflammatory interventions, i.e., high fish consumption or supplements containing n-3 PUFAs, should be the standard of care, along with pharmacotherapy, in treating patients with RA.”
And here is a graphic from that article showing the effect of SPMs (specialized pro-resolving mediators, derived from omega-3s):
Some omega-3 supplement studies have demonstrated no significant pain relief in osteoarthritis. Those studies did not reduce the consumption of pro-inflammatory n-6 fatty acids which compete with omega-3 fats for the enzymes which can lead to pro or anti-inflammatory mediators. They also did not measure the omega 6/omega 3 ratio in blood or tissues. Nor did they measure the omega-3 index (% of omega-3 achieved in red blood cell membranes, the gold standard for evaluating tissue levels achieved) This 2018 analysis stated:
“High Omega-3 (n-3) polyunsaturated fatty acids (PUFAs) are associated with lower levels of inflammatory mediators, anti-nociception, and adaptive cognitive/emotional functioning. High Omega-6 (n-6) PUFAs are associated with inflammation, nociception, and psychological distress. While findings related to n-3 supplementation in knee OA are mixed, consideration of the n-6:n-3 ratio and additional outcome measures may provide improved understanding of the potential relevance of these fatty acids in OA”
The authors went on to access blood n-6/n-3 ratios in patients with OA and found the following:
“The high ratio group reported greater pain and functional limitations, (all p’s<0.04), mechanical temporal summation (hand and knee, p<0.05), and perceived stress (p=0.008) but not depressive symptoms.”
“In adults with knee pain, a high n-6:n-3 ratio is associated with greater clinical pain/functional limitations, experimental pain sensitivity, and psychosocial distress compared to a low ratio group.”
The anti-inflammatory diet that I follow and recommend eliminates the major sources of excess omega-6 in the diet, specifically the “vegetable oils” which are actually seed, grain, and legume oils predominated by soy oil, corn oil, peanut and cottonseed oil present in cooking “vegetable oils” and processed foods. A table that displays the ratio of omega 3 to omega 6 in various oils can be found here. Note that this table does not reveal the amounts of MUFA (mono unsaturated fatty acids) which are arguably “heart healthy”. Nor does it address the important issue of protective polyphenols and anti-oxidants (such as in Extra Virgin Olive oil aka EVOO). So do not make choices of oil based only on the omega-3/6 ratio.
Another consideration in choosing oils for cooking (as opposed to salad dressing) is the smoke point. Under high heat, oils are subject to oxidation which creates a proinflammatory effect when consumed. Refined Avocado oil has the highest smoke point (520 degrees F). But we digress. Back to pain and arthritis.
“omega-3 polyunsaturated fatty acids (PUFA) have demonstrated an influential role in the progression of OA, resulting in the reduction of cartilage destruction, inhibition of pro-inflammatory cytokine cascades, and production of oxylipins that promote anti-inflammatory pathways.”
“Research has demonstrated a positive effect on the modulation of OA symptoms through diet and exercise to promote an anti-inflammatory environment. More specifically, omega-3 PUFAs have demonstrated a reduction in inflammatory biomarkers and cartilage degradation, counteracting the natural disease state of OA. In addition to their chondroprotective role, omega-3 supplementation has been shown to have indirect positive effects on muscle tissue recovery following exercise, which is necessary to prevent the progression of OA and maintain an independent, healthy lifestyle. The effects of omega-3 supplementation on the disease state of OA and its symptoms remain inconclusive. Further clinical trials utilizing human participants are warranted to provide a conclusive recommendation on standardized supplementation of omega-3 for the modulation of osteoarthritis.”
Given the cardioprotective effects, discussed in my last post (including an 80% reduction in sudden death at the highest quintile of omega-3 index) and other benefits (reduction in all cause mortality with high tissue levels), there are many reasons to include large amounts of low mercury fatty fish (wild Alaskan salmon, sardines, herring, trout) in the diet and to consider supplementation when your omega 3 index is < 8%. Likewise, in the presence of arthritis and pain, getting tissue levels of omega 3 up and reducing excessive pro-inflammatory omega 6 will likely provide significant benefit.
Here is a graphic with the omega 3 content of some foods.
And another:
As mentioned in my previous post about omega-3 and cardiovascular health, 1800 mg of omega-3 FA daily is adequate in most people to achieve and omega-3 index of 8%, the level at which cardiovascular protection is greatest.

The benefit of omega-3 supplementation has been debated in the cardiology and nutritional literature for many years. Most studies of supplementation have failed to measure tissue levels achieved and often used very low doses. But when tissue levels were measured, either in the serum or red blood cell membrane, the studies consistently demonstrated significant reductions in all-cause mortality and cardiovascular mortality associated with high levels of omega-3 fatty acids.
In addition, higher levels of omega 3 are associated with >=80% reduction in sudden death associated with acute myocardial infarction (acute MI) and > 80% reduction in sudden death in cohorts without known coronary artery disease followed long term.
Two Coronary CT Angiogram (CCTA) studies demonstrated that patients with stable coronary artery disease on statin therapy randomized to high dose EPA and DHA had “prevention of coronary plaque progression when an omega-3 fatty acid index >= 4% was achieved.”
Another CCTA study demonstrated that patients receiving omega 3 supplementation had significantly less coronary atherosclerotic “high risk” lipid rich plaque prevalence (3.8% versus 32%) and lower total non-calcified plaque burden independent of cardiovascular risk factors compared to matched controls not receiving omega 3 supplements.
Omega 3 supplementation after an acute myocardial infarction has been found to reduce infarct size, reduce scaring (fibrosis), and enhance heart tissue healing. (Randomized controlled clinical trial) However a post MI study in 1027 elderly patients randomized to receive 1.8 grams per day of EPA+DHA versus a control group receiving corn oil showed no reduction in the primary composite cardiovascular endpoint between the two groups at 2 years but a higher incidence of AF in the omega 3 group that did not reach statistical significance.
Recently a study, widely reported by the lay press, suggested that high dose omega-3 supplementation was associated with increased risk of atrial fibrillation (AF). These results conflicted with previous studies which demonstrated just the opposite, specifically prior studies demonstrated reduced risk of AF. The more recent study suffered a significant design flaw. The study in question failed to make statistical adjustment for the increased life span associated with higher levels of omega-3. Since age is a primary risk factor for AF, any intervention which increases life span would be expected to result in more AF over the lifetime of the patients as they aged (i.e., more elder years results in increased risk of AF). Therefore, statistical adjustment for that effect should be employed, but was not done in the study.
Unfortunately, science journalism has deteriorated to a state where the conclusions of study authors are most often quoted without interpretation or context, and without critical analysis or comparisons with previous studies that may have demonstrated opposing results.
In addition to large well-designed studies that have suggested a reduced risk of AF associated with omega-3 fatty acids, there have been natural experiments that provide reassuring information. The indigenous Inuit people of Greenland, for example, historically consumed large amounts of omega-3 in their diet with no evidence of increased risk of AF. In fact, before the introduction of western processed foods, estimates of AF among the Inuit were 0.6% (1963) compared to a “worldwide prevalence of AF in adults between 2 and 4%, between one and two percent in Canadian and the general US population and between 0.5% and 3% in most low- and middle-income countries.” A more recent study of Greenland yielded a prevalence of 1.4% likely reflecting a change in habits consisting of less exercise, more tobacco use and a shift to a more Western diet.
Still, multiple studies that used high dose omega 3 supplements in patients with known cardiac disease suggest an increased risk of AF. A good review of omega-3 fatty acids and atrial fibrillation was published in the Korean Journal of Internal Medicine, referenced below.
My interpretation of the complex data in this area is as follows.
At supplemental doses of EPA+DHA above 1.8 grams per day (and perhaps above 1 gram per day) in patients with known coronary artery disease (CAD), at high risk of CAD, or following a myocardial infarction, the risk of AF is increased by about 25% (relative risk). But the risk of lethal ventricular arrythmias (sudden death) associated with myocardial infarction (heart attack) is 80% lower in patients with a red blood cell omega 3 index of >=8. In people without known CAD, an omega-3 index >=8% is associated with an 80% reduction in sudden cardiac death. CCTA studies show significantly lower unstable “vulnerable” plaque in patients on omega-3 supplements. Similarly, omega 3 supplementation in patients on statins associates with halted plaque progression determined by serial CCTA in non-diabetics.
In addition, higher tissue levels of omega 3 are associated with significantly reduced all-cause, cardiovascular, and cancer mortality.
Omega-3 fatty acids are the chemical precursors of SPMs, specialized pro-resolving lipid mediators which help resolve inflammation. We know that cardiovascular events are driven by chronic inflammation in the walls of arteries, often mediated by insulin resistance. Chronic inflammation contributes to atherosclerosis (production of plaque in the artery wall) as well as cardiovascular events that result when unstable plaque ruptures. Studies suggest that n-3 fatty acids may have antiarrhythmic properties with membrane-stabilizing effects in addition to antithrombotic and anti-inflammatory properties on the endothelial level. Basic science, observational studies and clinical trials have demonstrated that higher tissue levels of omega 3 fatty acids are associated with longer health span and lifespan. This understanding must be balanced with a probable increased risk of AF in certain clinical situations associated with high dose omega-3 supplements as described above (people with known CAD, high risk for CAD, or following and MI). Note that current AHA and ACC dietary guidelines include at least 2 servings of fatty fish per week, one serving provides approximately 1800 mg of omega-3.
Getting omega-3 fatty acids from cold water fatty fish would be ideal. Unfortunately, many individuals do not like salmon, sardines, mackerel or herring and simply will not consume enough of this fish to achieve protective tissue levels. Other species of fish and seafood provide much less amounts of omega 3. Another consideration is that individuals process omega 3 fats differently so different amounts of omega 3 will be necessary to reach the same protective levels in tissue. You can obtain a red blood cell omega-3 index using a home kit and a finger prick without a prescription (https://omegaquant.com/). The sample is mailed in to the lab and results reported directly to you. I have no financial relationship with these folks.
Bill Harris, PhD, is widely published in the area of omega-3 science. He developed the first clinically useful tissue assay which measures the % of omega 3 fat in red blood cell membranes, the “omega-3 index” which is the gold standard for omega 3 research and clinical testing. Although serum levels correlate with the red blood cell index, the later reveals dietary consequences of a 2-3 month period while serum levels reflect just a few days of most recent dietary habits. The red blood cell omega 3 index is analogous to the hemoglobin A1c which reveals average blood sugars over a 2–3-month period. Bill Harris suggests that 1800 mg per day of omega 3 fat consumption (food plus supplements) will achieve an index of >= 8% in most individuals.

“Here we report the results of a de novo pooled analysis conducted with data from 17 prospective cohort studies examining the associations between blood omega-3 fatty acid levels and risk for all-cause mortality. Over a median of 16 years of follow-up, 15,720 deaths occurred among 42,466 individuals. We found that, after multivariable adjustment for relevant risk factors, risk for death from all causes was significantly lower (by 15-18%, at least p < 0.003) in the highest vs the lowest quintile for circulating long chain (20-22 carbon) omega-3 fatty acids (eicosapentaenoic, docosapentaenoic, and docosahexaenoic acids).Similar relationships were seen for death from cardiovascular disease, cancer and other causes”
Blood Levels of Long-Chain n–3 Fatty Acids and the Risk of Sudden Death Authors: Christine M. Albert, M.D., M.P.H., Hannia Campos, Ph.D., Meir J. Stampfer, M.D., Dr.P.H., Paul M. Ridker, M.D., M.P.H., JoAnn E. Manson, M.D., Dr.P.H., Walter C. Willett, M.D., Dr.P.H., and Jing Ma, M.D., Ph.D.
We conducted a prospective, nested case–control analysis among apparently healthy men who were followed for up to 17 years in the Physicians’ Health Study. The fatty-acid composition of previously collected blood was analyzed by gas–liquid chromatography for 94 men in whom sudden death occurred as the first manifestation of cardiovascular disease and for 184 controls matched with them for age and smoking status.
RESULTS
Base-line blood levels of long-chain n–3 fatty acids were inversely related to the risk of sudden death both before adjustment for potential confounders (P for trend = 0.004) and after such adjustment (P for trend = 0.007). As compared with men whose blood levels of long-chain n–3 fatty acids were in the lowest quartile, the relative risk of sudden death was significantly lower among men with levels in the third quartile (adjusted relative risk, 0.28; 95 percent confidence interval, 0.09 to 0.87) and the fourth quartile (adjusted relative risk, 0.19; 95 percent confidence interval, 0.05 to 0.71).
CONCLUSIONS
The n–3 fatty acids found in fish are strongly associated with a reduced risk of sudden death among men without evidence of prior cardiovascular disease.

Compared with control groups, risk ratios for cardiac mortality indicated benefit from statins (0.78; 95% CI, 0.72-0.84), resins (0.70; 95% CI, 0.50-0.99) and n-3 fatty acids (0.68; 95% CI, 0.52-0.90).

Conclusions: Omega-3-PUFA supplementation is associated with less coronary atherosclerotic “high-risk” plaque (lipid-rich) and lower total non-calcified plaque burden independent on cardiovascular risk factors. Our study supports direct anti-atherogenic effects of Omega-3-PUFA.
Conclusions: EPA and DHA added to statins prevented coronary plaque progression in nondiabetic subjects with mean LDL-C <80 mg/dL, when an omega-3 index ≥4% was achieved. Low omega-3 index <3.43% identified nondiabetic subjects at risk of coronary plaque progression despite statin therapy
Among 3326 US men and women ≥65 years of age and free of AF or heart failure at baseline, plasma phospholipid levels of eicosapentaenoic acid, docosapentaenoic acid, and docosahexaenoic acid were measured at baseline by use of standardized methods. Incident AF (789 cases) was identified prospectively from hospital discharge records and study visit ECGs during 31 169 person-years of follow-up (1992-2006).
Conclusions: In older adults, higher circulating total long-chain n-3 PUFA and docosahexaenoic acid levels were associated with lower risk of incident AF (atrial fibrillation). These results highlight the need to evaluate whether increased dietary intake of these fatty acids could be effective for the primary prevention of AF.
An omega-3 index of less than 4% is associated with increased CHD risk, particularly for sudden cardiac death. In contrast, an omega-3 index of more than 8% is associated with low CHD risk, whereas the range between 4% and 8% is considered intermediate risk

Establishing future research and intervention directions.
The 2022 United Nations Climate Change Conference or Conference of the Parties of the UNFCCC, more commonly referred to as COP27, is the 27th United Nations Climate Change conference and is being held from 6 November until 18 November 2022 in Sharm El Sheikh, Egypt.
The summit presented an opportunity for nutritionist and healthy food advocate Diana Rogers to offer an alternative to the false narrative so prevalent today regarding beef, global warming, and nutrition.
The false narrative states that methane released by raising cattle is a major contributor to global warming and meat is unhealthy. This narrative diverts attention from the real source of global warming, fossil fuels. Importantly this narrative ignores the importance of meat consumption for human health as well the importance of ruminant grazing for soil regeneration as well as economic and food stability for many poor people. Lastly it ignores the contribution of properly raised cattle, lamb and other animal food sources to carbon sequestration.
By most estimates, the number of ruminants roaming our plains and forests before the industrial era was equal to the number of wild and domestic ruminants in the US today.
Global warming was not a problem before industrialization. This simple fact should belie the false narrative.
Diana Rogers has been a champion for honest science in this debate. She is the only nutritionist to present information at the conference. She has recently posted on twitter the slides presented at the global COP27.
Here are some of her slides that speak for themselves.
Well managed cattle when raised in an integrative fashion with crops in a process called regenerative agriculture:
sequester carbon
regenerate soils
provide high quality nutrition to an increasingly diseased and nutrient deficient population
Reduce the need for fossil fuels and fossil-based fertilizer, providing natural fertizlizer
Mono-agriculture, which predominates US farmland (90%)
destroys soil, killing essential microbes and converting soil to dirt
converts cropland to desert contributing to air pollution (dust storms), soil erosion and floods
releases carbon into the atmosphere during tillage
utilizes Roundup-ready crops that are sprayed with roundup before harvest (carcinogenic, endocrine disruptor which contaminates our food and water)
consumes large amounts of fossil fuel and fossil-based fertilizer creating a large carbon footprint.
Kills more innocent bystander animals directly (during tillage, planting, and harvest) and indirectly (habitat destruction), then the number of animals slaughtered for human consumption (are cattle more worthy of protection than rabbits, squirrels, mice, birds, snakes etc., all of which are killed by mono-agriculture practices?)
Depletes our soil, and therefore our food, of nutrients, reducing the nutrient content of vegetables and fruits. (example: 8 oranges today have the same nutrients as 1 orange 100 years ago)
This affects health, brain development and educational achievement.
Livestock contribute to food security.
It is time for the narrative about eating and raising animal sources of protein to change. We need to produce rather than destroy soil, enhance rather than degrade the nutrient value of crops, sequester rather than release carbon, utilize ruminant waste for fertilizer instead of fossil based fertilizer, and provide our children and adults with nutrient dense healthy food that includes animal sources of protein.
The cow-methane narrative ignores much of science and diverts our attention from the source of global warming, the burning of fossil fuels.
The Global Food Justice Alliance advocates for the right of all people to choose nutrient-dense foods such as meat, milk, and eggs, which are critical for nutritious, environmentally sustainable, and equitable food systems that can sustain both human life and the planet.
Here are some of the bullet points from Diana Rogers’ presentation at COP27
Many are claiming meat is unhealthy, unsustainable, unnecessary and unethical, but are these claims justified? Are we looking at livestock agriculture in a holistic way? What strong evidence do we have to prove this?
Or are policymakers and others pushing for the removal or dramatic reduction in livestock suffering from “carbon tunnel vision”? Are they failing to account for the value meat plays to human health, rural economies, and overall ecosystem function?
Worldwide, 1 in 2 children and 2 in 3 women have at least one micronutrient deficiency, wreaking havoc on immune systems, hindering growth and development, and limiting human potential.
These deficiencies are not limited to low- and middle-income countries. Iron deficiency alone impacts 1 in 5 women in the US, where we’re told to eat less meat, which is the best source of iron.
The leading micronutrient deficiencies are: iron, zinc, folate, vitamin A, vitamin D, and B12. As many as 40% of children and 70% of women have multiple deficiencies at the same time. Animal-sourced foods are the only or best source of all those above except folate (which is found in liver, but plant-based foods like lentils are also a good source).
If we are to discuss a “climate friendly diet”, we need to consider not just “emissions” but the nutritional value of the food per serving (not per calorie), because a further shift away from meat will do more harm, especially to women and children.
The evidence against meat for health reasons is based on shaky science. There are no experimental studies showing meat causes harm, only associations, but we know typical meat eaters also tend to partake in other unhealthy behaviors like smoking and drinking. When accounting for these factors, red meat has not been found to cause ill health.
When it comes to processed meat, the science is also not significant. Your overall risk of getting colon cancer is 5.6% and eating 5 slices of bacon every single day for your whole life would raise your risk to 6.6%. This is not statistically significant. However, the media reports this as a 20% increase, which is misleading to consumers.
We only have one experimental study looking at meat vs. less meat, which was done in Kenyan school children. It proved that adding meat increased their academic scores, their physical ability, and their behavior.
Because livestock can “up-cycle” nutrient poor food (food scraps, waste from the plant-protein industry, and grains) into protein, iron, B12, and other critical nutrients, they are a net win for our food system.
Livestock are less susceptible to drought or extreme weather.
12% of the world’s population rely solely on livestock for their livelihood.
Women in ½ the countries worldwide are unable to own land, but in many cases, they can own livestock, improving gender equality and household nutrition.
Plus, most of our agricultural land is too dry, brittle, or rocky to crop, but livestock thrive on this marginal land.
Food choice is a privilege. Those with the means to push away nutritious food like meat should not be creating policies limiting access to nutrients in meat, which is also a culturally appropriate food to most. This is moral and cultural imperialism.
We need a lot more recognition that livestock can provide critical ecosystem function and micronutrients.
Exercise, especially out of doors in a green space, supports the immune system
Get some sunshine and make sure you have adequate Vitamin D levels. Supplement with Vitamin D3 to get your levels above 30 ng/ml, >40ng/ml arguably better.
Eliminate sugar-added foods and beverages from your diet. These increase inflammation, cause metabolic dysfunction, and suppress immunity.
Eliminate refined-inflammatory “vegetable oils” from your diet, instead eat healthy fat.
Clean up your home environment and minimize your family’s exposure to environmental toxins by following recommendations at EWG.org with regards to household products, personal care products, and organic foods. (https://www.ewg.org/)
Drink water filtered through a high quality system that eliminates most environmental toxins. (Such as a Berkey or reverse osmosis filter)
HEPA filters or the home-made version (Corsi-Rosenthal box) used in your home or workplace can reduce circulating viral load by 80%. This works for any respiratory virus transmitted by aerosol and this winter we have the triple threat of RSV, Influenza, and SARS-CoV-2. It also decreases indoor air pollution.
If you are eligible for vaccination, consider protecting yourself and your neighbor with a few jabs. Age > 50 and/or risk factors (Diabetes, pre-diabetes, insulin resistance, hypertension, obesity, heart disease, COPD, asthma, cancer treatment, immune suppression) suggests benefit from a booster. Risk for complications of boosters in adolescents, especially males, without risk factors, may equal benefit. Previous infection with Covid can be considered as protective as a booster. Discuss risk vs benefits with your doctor.

An excellent article recently published in the Atlantic was so well written that I have cut and pasted important snippets to help create this post. The review confirms many findings uncovered in my reading of several scientific publications.
20 to 30 percent of patients report brain fog three months after their initial infection, as do 65to85 percent of the long-haulers who stay sick for much longer.
Of long COVID’s many possible symptoms, brain fog “is by far one of the most disabling and destructive,”
It is more profound than the clouded thinking that accompanies hangovers, stress, or fatigue.
It is almost always a disorder of “executive function”—the set of mental abilities that includes:
focusing attention,
holding information in mind, and
blocking out distractions.
Patients state they often lose focus mid-sentence.
Difficulty with simple tasks impairs activities of daily living.
“I couldn’t unload a dishwasher, because identifying an object, remembering where it should go, and putting it there was too complicated.”
The memories are there, but with impaired executive function, the brain neither chooses the important things to store nor retrieves that information efficiently.
Most people with brain fog are not so severely affected, and gradually improve with time. But even when people recover enough to work, they can struggle with minds that are less nimble than before.
“I’ve had surgeons who can’t go back to surgery, because they need their executive function,” Monica Verduzco-Gutierrez, a rehabilitation specialist at UT Health San Antonio.
That specific constellation of problems also befalls many people living with HIV, epileptics after seizures, cancer patients experiencing so-called chemo brain, and people with several complex chronic illnesses such as fibromyalgia.
People with brain fog also excel at hiding it: to protect their jobs when still able to work, or to protect their reputation, or out of embarrassment.
“I know my value in many people’s eyes will be diminished by knowing that I have these cognitive challenges.”
Individuals with previously above average cognitive ability often test “normal” but suffer significant loss compared to their prior ability.
A team of British researchers analyzed data from the UK Biobank study. The findings revealed structural changes in the brain with loss of tissue on MRI scans that correlates with symptoms.
They found that even mild infections can slightly shrink the brain and reduce the thickness of its neuron-rich gray matter. At their worst, these changes were comparable to a decade of aging.
They were especially pronounced in areas such as the parahippocampal gyrus, which is important for encoding and retrieving memories, and the orbitofrontal cortex, which is important for executive function.
In most cases the virus probably harms the brain without directly infecting it.
Inflammatory chemicals can travel from the lungs to the brain, where they disrupt cells called microglia (immune cells in the brain).
In their presence, the hippocampus—a region crucial for memory—produces fewer fresh neurons, while many existing neurons lose their insulating coats (demyelination), so electric signals now course along these cells more slowly.
These are the same changes seen in cancer patients with “chemo fog”.
Neuro-inflammation is “probably the most common way” that COVID results in brain fog, but that there are likely many such routes, such as reactivation of dormant viruses such as Epstein-Barr virus, which has been linked to conditions including ME/CFS and multiple sclerosis.
These problems can be exacerbated or mitigated by factors such as sleep and rest, which explains why many people with brain fog have good days and bad days.
Although other respiratory viruses can wreak inflammatory havoc on the brain, SARS-CoV-2 does so more potentlythan influenza.
For adults following SARS CoV-2 infection:
risks of cognitive deficit (known as brain fog), dementia, psychotic disorders, and epilepsy or seizures were still increased at the end of the 2-year follow-up period.
For children following SARS CoV-2 infection:
in the 6 months after SARS-CoV-2 infection, children were not at an increased risk of mood (HR 1·02 [95% CI 0·94–1·10) or anxiety (1·00 [0·94–1·06]) disorders, but did have an increased risk of cognitive deficit, insomnia, intracranial haemorrhage, ischaemic stroke, nerve, nerve root, and plexus disorders, psychotic disorders, and epilepsy or seizures (HRs ranging from 1·20 [1·09–1·33] to 2·16 [1·46–3·19])…. Unlike adults, cognitive deficit in children had a finite risk horizon (75 days) and a finite time to equal incidence (491 days).
The fact that neurological and psychiatric outcomes were similar during the delta and omicron waves indicates that the burden on the health-care system might continue even with variants that are less severe in other respects.
There are no proven drug treatments for long-haulers.
But there is hope.
Cancer researchers have developed drugs that can calm inflamed microglia in mice and restore their cognitive abilities;
“Metformin can promote the regeneration of neural precursor cell populations and improve cognitive function in a preclinical model of cranial radiation and a pilot clinical study of children after cranial radiation and chemotherapy.”
With regard to long-haulers, better sleep, healthy eating, and other generic lifestyle changes can make the condition more tolerable. Breathing and relaxation techniques can help people through bad flare-ups; speech therapy can help those with problems finding words.
“Some people spontaneously recover back to baseline,”
The largest group of long-haulers—those whose brain fog has improved but not vanished, can “maintain a relatively normal life, but only after making serious accommodations,”
Patients struggle to make peace with how much they’ve changed and the stigma associated with it, regardless of where they end up.
People with ME/CFS learned this lesson the hard way, and fought hard to get exercise therapy, once commonly prescribed for the condition, to be removed from official guidance in the U.S. and U.K.
In summary:
Brain fog can occur even after mild or asymptomatic Covid-19.
Although many patients improve over time, many are left with disability that can range from mild to incapacitating.
Although these symptoms can occur following any viral infection, SARS CoV-2 seems to produce this with greater frequency compared to other viruses.
Chronic brain inflammation is the likely cause in many individuals.
Reactivation of Epstein Barr and/or other dormant viruses is suggested by various immune markers.
The immune signature also suggests an immune response that mimics persistent infection in the absence of live SARS CoV-2 virus.
Post exertional malaise following physical or mental exercise is a common and debilitating symptom without proven treatments. However there are guidelines that may help mitigate this devastating condition.
Exercise, especially out of doors in a green space, supports the immune system
Get some sunshine and make sure you have adequate Vitamin D levels. Supplement with Vitamin D3 to get your levels above 30 ng/ml, >40ng/ml arguably better.
Eliminate sugar-added foods and beverages from your diet. These increase inflammation, cause metabolic dysfunction, and suppress immunity.
Eliminate refined-inflammatory “vegetable oils” from your diet, instead eat healthy fat.
Clean up your home environment and minimize your family’s exposure to environmental toxins by following recommendations at EWG.org with regards to household products, personal care products, and organic foods. (https://www.ewg.org/)
Drink water filtered through a high quality system that eliminates most environmental toxins.
If you are eligible for vaccination, consider protecting yourself and your neighbor with a few jabs. Age > 50 and/or risk factors means clear benefit from a booster.

My friend Diana Rogers, started the Global Food Justice Alliance. This organization brings unbiased science to the discussion of meat consumption as it relates to health AND the environment. As discussed previously (see regenerative agriculture posts), properly raised ruminants (beef, pork, lamb, etc.) are ecologically sound, help create soil and fight climate change, and provide important nutrient dense food for people of all ages. The anti-meat narrative in popular media presents a false and dangerous position that threatens our environment, soil conversation/creation, and health.
Regenerative sustainable agriculture (depicted on the right) , minimizes use of fossil fuel and fossil oil based fertilizer. Instead it utilizes ruminant animal waste for fertilizer, creates living soil and biologic diversity. Mono-agriculture depicted on the left, destroys soil, depletes nutrients in food, contaminates our food with pesticides, creates downstream runoff environmental degradation, and contributes to climate change. The documentary “Kiss the Ground” documents these important concerns.
In the context of the COVID 19 pandemic I will close with the usual summary.

I recently gave a talk at the AHS 2022 meeting held at UCLA. You can view the video here:
This first slide gives a good overview.
The presentation covers a quick review of my presentations given last year at the PAH 2021 annual meeting (virtual) with additional information on long Covid.
Multiple nutrients acting synergistically support a balanced response to viral infections, including SARS CoV-2. Here is a picture.
The take home message is that no single nutritional intervention is likely to have significant impact with an acute infection unless all but one nutritional component is optimal. Nevertheless, there is compelling evidence that Vitamin D deficiency is rampant in the developed world and if one nutritional intervention is likely to be of benefit, Vitamin D supplementation, particularly in high risk populations, presents the most likely candidate. As usual, preventive supplementation would be preferable to rescue high dose intervention.
In a study of frail elderly hospitalized patients, regular vitamin D supplementation was associated with decreased mortality as demonstrated here. Compared to no supplementation, regular supplementation was associated with a 93% reduction in risk of death.
A study from Spain with very high dose Vitamin D in the form of Calcifediol showed significant benefit in hospitalized patients, suggesting that Vitamin D deficiency was prevalent in that population and that such a treatment intervention should be widely considered.
Calcifediol Treatment and COVID-19-Related Outcomes
The following graphic from another nutrition review article, with red additions added by myself, demonstrates the complex interaction between nutrition and the two main components of our immune system, innate immunity (immediate response) and adaptive immunity (based on immune memory). Again red highlights added by yours truely.
And here is a slide from my lecture with quotes from that article.
Yet most Americans are deficient in many of these essential nutrients as depicted here. The percentages represent the % of Americans that fall below the estimated amount required to prevent deficiency in HALF of adults (a very low standard).
The EAR is a very low bar to meet, yet many Americans fall below even that low standard.
The SARS CoV2 virus interferes with a crucial component of the the initial (innate) immune response, the production of interferon 1 and the signaling of interferon one to immune cell mediators as depicted in this graphic.
SARS CoV2 on the left is compared to Virus X on the right. On the left interferon 1 (IFN) production and signaling is blocked by the virus, interfering with an effective and controlled immune response, on the right IFN is not blocked. A cascade of events results in TOO LITTLE, TOO LATE, AND THEN TOO MUCH of an immune response, producing a cytokine storm.
Obesity, insulin and leptin resistance, also interfere with the production and signaling of interferon. The result is that people with insulin and leptin resistance (pre-diabetes, Type 2 Diabetes as well as sarcopenia) experience a double hit. First the virus itself disrupts the immune response and superimposed upon the viral effect is the effect of insulin and leptin resistance on the immune response.
SOCS: suppressor of cytokine signaling. Several recent viral studies have shown that viral genes can hijack SOCS1 to inhibit host antiviral pathways, as a strategy to evade host immunityOn the left Interferon production and signaling are normal and a successful immune response is mounted. On the right the presence of insulin and leptin resistance, associated with obesity results in an initial inadequate response and a late excessive response. TOO LITTLE, TOO LATE, THEN TOO MUCH.
Factors that can quickly impact insulin and leptin resistance include all the components of an ancestral lifestyle depicted in my website graphic. A paleolithic or ancestral diet that eliminates sugar added foods and beverages, replacing those empty calories with nutrient dense foods, exercise, adequate restorative sleep, stress reduction, avoidance of environmental toxins, social connection. All of these affect health in general, mitigate insulin and leptin resistance, and support a balanced immune response to viral infection. The circle of health depicted below is surrounded by the many deleterious aspects of modern living. Thus, a mismatch between our evolutionary biology and present day life.
Here is a slide from my lecture that lists many lifestyle factors that can impact infection with any virus, including SARS CoV-2
My lecture also included discussion of Long COVID, theories of etiology and pathophysiology which will be discussed in my next post.
For the full lecture which is about 34 minutes long, please follow the link above.

Again, another biased article claims to demonstrate the dangers of red meat. There are so many problems with the author’s analysis and conclusions it is hard to know where to begin. Rather than go through the nitty gritty here, just head on over to this analysis to read another debunking of the same litany of bad science.

Earlier this year I gave 2 presentations on this topic at the (virtual) annual meeting of Physicians and Ancestral Health, a physician organization dedicated to incorporating evolutionary biology and lifestyle recommendations into the practice of medicine. Here is the first slide:
And here are some very important references:
Please note that this lecture was given before the delta variant arrived so the data applies to the pre-delta period.
MI= Myocardial Infarction (heart attack with loss of muscle), PE=Pulmonary Embolus, DVT= Blood Clots in legs, SIRS= Systemic Inflammatory Response Syndrome
I will skip several of the slides and get to the nutritional immunology and other lifestyle factors.
This slide shows many lifestyle factors that interact with the immune system. The “12% metabolic health” refers to a study demonstrating that only 12% of American adults are metabolically healthy, which will be explained later. Dysbiosis refers to an imbalance in gut bacteria favoring inflammation and immune compromise. The rest should be self explanatory but discussed in detail later in this series.
Here is the very busy slide that summarizes nutritional immunology:
w3/w6 refers to the omega 3 to omega 6 ratio in the diet, ROS= Reactive oxygen species (oxidative stress), CH: carbohydrates; GALT: gut-associated lymphoid tissue; GPRs: G-protein-coupled receptors; FA: fatty acids; GI/GL: glycemic index/load; RAR/RXR: retinoic acid receptor/retinoid X receptor; SCFA: short-chain fatty acids; TF: transcription factors; VDR: vitamin D receptor.
Key points in this slide:
Omega 3 fats from fatty fish fight inflammation, excess omega 6 fats from refined “vegetable oils” (corn, soy, cotton seed, sunflower seed, safflower, etc.) contribute to inflammation and blood clots, contributing to cytokine storm and bradykinin storm.
Vitamin D interferes with the virus at multiple points.
Adequate iron (Fe) from meat and seafood is essential for immune function (Iron from plant sources is much less bioavailable compared to meat and seafood.)
Adequate complete protein (not available from vegan diets) is essential for immune function.
Zinc and selenium (both found in seafood and meat) are essential for multiple protective pathways in the immune system (enhancing response to infection and mitigating excessive inflammatory response as cofactors for antioxidant enzymes)
Sugar and high glycemic foods cause inflammation, high blood sugars suppress the immune system
Dietary fiber supports a healthy gut microbiome which in turn suppresses inflammation and provides the gut lining with SFAs (gut epithelium requires SFAs for energy and function, gut barrier function needs SFAs)
Phenolic compounds in colorful vegetables and berries modulate multiple essential immune pathways that can inhibit viral replication.
Carotenoids, phenolics support several vital immune pathways.
Omega 3 fats are the building blocks of chemicals that help resolve inflammation and mitigate against cytokine storm and bradykinin storm.
Multiple vitamins and phenolics support our internal anti-oxidant system.
To get a balanced protein intake we should eat “nose to tail”. Include connective tissue (home made bone broth is a great source) and organ meats (from grass fed/finished ruminants) in addition to muscle meat.
Here is another busy slide that presents more detail, note the reference at the bottom of the slide to read more.
Sorry for the small print but you can see the blow up on line by going here.
So does the “Standard American Diet” meet these nutritional needs to support a healthy immune system?
The % above represent the % of American adults with intakes BELOW the EAR (Estimated Average Requirement) for various vitamins and minerals. But note the definition of EAR:
“nutrient intake value that is estimated to meet the requirement of half the healthy individuals to avoid symptoms of a clinical or subclinical deficiency” (NOT OPTIMAL LEVELS for immune function)
Note also that this study did not consider omega-3s, phytonutrients, flavonoids, polyphenols, fiber, etc., all of which are essential to a robust immune response to any virus including SARS CoV-2.
With regards to omega 3 vs omega 6 fats:
Omega 3 fats (EPA and DHA) found in seafood fights inflammation, blood clots. DHA and EPA are the building blocks of SPMs which help RESOLVE INFLAMMATION (MITIGATE CYTOKINE STORM)
We will return to this topic in my next post. We are just scratching the surface of a complex system.
In the context of the COVID 19 pandemic I will close with the usual summary.
