Covid-19 Update: What to Eat to Lower Risk of Respiratory Infection

RVAchironeuro • March 21, 2021

Hello again everyone:

As the science shows, what we eat influences our immune system, and in this paper they show that increasing daily fruit and vegetable consumption significantly lowers the risk of many disease, including respiratory tract infections.

Specifically, the research is summarized:

CONCLUSIONS: Higher intakes of fruit and vegetables were associated with lower mortality; the risk reduction plateaued at ≈5 servings of fruit and vegetables per day. These findings support current dietary recommendations to increase intake of fruits and vegetables, but not fruit juices and potatoes. (1)

Bottom Line: This research revealed that 2 servings of fruit and 3 servings of vegetables per day was significantly better that 2 total per day, but interestingly, there was very little benefit seen to eating more than the 5 servings. This has led to the saying “5-per-day” is the yardstick that they measure an optimal diet. They said that there were statistically important reductions in:

  • Total mortality
  • Cardiovascular mortality
  • Cancer mortality
  • Respiratory disease mortality (obviously it is Covid that is important now)

Notably, fruit juice, potatoes and starchy vegetables were not associated with improvements, and as we all know, it this type of food that is related to a higher carbohydrate content that requires insulin and extra insulin is not health building.

There were several factors about the paper that were less than optimal, such as they do not tell us if the people ate fresh, frozen or canned fruits and/or vegetables. Data shows that canned and/or frozen fruits and vegetables have lower nutrient profiles, and to me this means that it would have better if they were able to note who ate what type of processed or unprocessed foods…my bet is that whole, fresh, unprocessed foods would yield better results. Even still, they were confident in their conclusions as the results were strong enough to merit discussion and publication.

Hey…our mothers told us to eat our fruits and vegetables, however in the U.S. the average consumption is only 2 total servings per day…so lots of room for improvement in a really easy and tasty application of this knowledge: EAT REAL FOOD!!! There is real power in our food choices, so please make the best ones!!

Health News Update: Inflammaging is Bad News

By Mark Smith • August 25, 2025
Hello everyone: I think I have mentioned inflammaging before but never really focused on it. So, let’s dig into this interesting topic. Inflammaging is when chronic, low-grade inflammation develops with age as dietary and environmental stress accumulates, contributing to the development of all of the various age-related diseases and health issues. It results from a loss of control over systemic inflammation, which tends to come from an unbalanced and dysregulated immune system. One of the key drivers of inflammaging is diet…which means that one of the key tools to slow and reduce aging is our what we eat as well as what we don’t eat. In this paper, the authors reveal that the typical Western Diet (what science calls the Standard American Diet or S.A.D.) is the best example of a pro-inflammatory diet pattern. “ Conclusion: Inflammation is a key physiological process in immunity and tissue repair. However, during aging it becomes increasingly more chronic. In addition, we found that certain foods such as saturated fats have pro-inflammatory activity. Taking this into account, in this review we have proposed some dietary guidelines as well as a list of compounds present in foods with anti-inflammatory activity. It must be taken into account that the amounts used in the studies that detect anti-inflammatory activity of these compounds are very high, and the intake of a single food to achieve its anti-inflammatory power is not feasible. (My Comment: what this means is that it is the overall dietary pattern that matters the most.) However, the combination of foods rich in compounds with anti-inflammatory activity could exert beneficial effects during aging and in pathologies associated with inflammation and in reducing the detrimental effects of foods with pro-inflammatory activity. Therefore, we can conclude that the compounds in our diet with anti-inflammatory activity could help alleviate the inflammatory processes derived from diseases and unhealthy diets and thereby promote healthy aging. Thus, we can use diet not only for nourishment, but also as medicine.” https://pmc.ncbi.nlm.nih.gov/articles/PMC8389628/ anti-inflammatory diet and health aging https://www.healthline.com/health/5-minute-guide-to-inflamm-aging Bottom Line: We all must age, and how we do so is largely under our own control. To create an anti-inflammatory lifestyle is not that difficult, especially if you put it all together in stages. Start with a clean, whole-food, unprocessed plant-based food plan. And to begin, first focus on what you can add into your menus and use those additions to sort of crowd out the things that are more inflammatory…sugar, refined grains, processed and pre-packaged things. Set realistic goals such as going plant based one or two days a week, or even one meal…just start and gradually work up. It has to be doable so don’t stress. Next, start moving and doing regular exercise at least three times a week…and find what you enjoy doing and focus on that. Then add activities that de-stress you, whether that is socializing, church, meditation, prayer, yoga, etc. Overall, shift your attention to giving love to things that love you back. Sugar, drive-thru and processed food like thingies do not love you back but apples or kiwis or berries or veggies do. Sitting around does not love you back but going for a short walk after a meal does love you back. Hang out and give love to the people you really like to be with, they will most always love you back. Create a love you back lifestyle and see how you feel.

Health News Update: Blocking Internet on Smartphones Improves Mental Health

By Mark Smith • August 18, 2025
Hello everyone: I frequently hear about mental health issues with the people in our practice. They could be experiencing depression, or anxiety, feel flat, can’t focus or sustain attention, or may not feel well in general. These comments can come from anyone of any age…I can hear from parents about their kids, or it may be themselves experiencing these feeling. So, when I read this paper, it felt important to share it because we all seem to have mobile phones. Here is how the paper is summarized: “Concern about how smartphones affect users is widespread: half of American smartphone users—and 80% of those under age 30—worry that they use their device too much, and correlational research suggests that smartphone use is negatively related to mental health and cognitive functioning. However, few large-scale experiments have tested for causal effects. We report such an experiment, finding that blocking mobile internet for 2 weeks reduces smartphone use and improves subjective well-being (SWB) (including life satisfaction and positive affect), mental health (more than antidepressants), and sustained attention (as much as being 10 years younger). Despite the many benefits mobile internet offers, reducing the constant connection to the digital world can have large positive effects.” https://academic.oup.com/pnasnexus/article/4/2/pgaf017/8016017?utm_source=klaviyo&utm_medium=email&utm_campaign=%28Email%20-%20Chris%20Kresser%20General%20News%29%20Chris%27s%20Friday%20Favorites&utm_term=randomized%20controlled%20trial&utm_content=randomized%20controlled%20trial&_kx=fARhTo_gi8X3B_2-MaeO_RyzUl9tvT3tr4re-Dy7cNQ.my75y6 Bottom Line: It seems like a smartphone ‘timeout’ can be very beneficial for mental, emotional, physical health and can be an important part of stress reduction. The world today, with nearly instant communications, the almost constant bad and anxiety promoting news, and the fast pace of data consumption can add up to significantly stress us out and pull us down…or just simple keep us distracted. From what I can see, a ‘timeout’ may be just what the doctor ordered.

Health News Update: Diet can Alter Your Disease Trajectory

By Mark Smith • August 11, 2025
Hey there everyone: As you know, inflammation causes, perpetuates, and/or aggravates every known human condition, including aging. As we age, we become more vulnerable to non-communicable diseases such as heart attack, stroke, high blood pressure, cancer, diabetes, dementia, arthritis and more. How we eat can massively reduce our inflammatory burden and promote health as we age. It is your choice. One reason that I keep writing on this is that I keep running into the mindset that these diseases are inevitable and that there is nothing we can do about it. Plus, because there are so many different diets for sale out there, it becomes hard to know what to eat. What is important for you to know is that there is a growing scientific consensus about what to eat, but the media rarely mention it and our public health authorities don’t either. It definitely seems like money is more important than our health. So…consuming an overall low-inflammatory diet is what the science is adding up to show it is the healthiest way to go, plus it actually gives you power over your future. This is a great article worth the time it takes to read it as it is pretty comprehensive. Bottom Line: “To adopt an anti-inflammatory dietary pattern, it is recommended to replace refined grains with whole grains, substitute healthy fats (such as nuts, seeds and fatty fish) for saturated and trans fats and increase the consumption of colorful fruits and vegetables while reducing the intake of sugary and processed foods. Additionally, choosing lean protein sources like fish and legumes over red and processed meats, using herbs and spices (such as turmeric, ginger, garlic and cinnamon) in place of excessive salt and sugar and consuming probiotic-rich foods (such as yogurt and kefir) instead of processed and sugary snacks are advised. These dietary adjustments can help mitigate inflammation and promote overall health.” https://www.cambridge.org/core/journals/british-journal-of-nutrition/article/overview-of-antiinflammatory-diets-and-their-promising-effects-on-noncommunicable-diseases/AA3166846841DCC1B219C063F52E2A7F (anti-inflammatory diet)
