Your Brain on Food

Health News Update: Your Brain on Food                                                 10.13.25

Hello everyone: The type of food we consume will absolutely significantly positively or negatively impact our ability to think, remember, learn, behave, enjoy…in other words, everything that our brain does relies on the quality of food we eat. For most of us, poor food results in a downward change that is gradual, for others who may not be in top shape…they may notice right away that their mood or fog increases with poor food choices. This is especially true if the foods create inflammation. Today in our country, dementia is the 5th leading cause of death. Let that thought sink in for a moment. And now let that realization guide your food choices.

 

Diets that are nutrient dense, lower in calories, unprocessed, and predominantly whole-foods that are mostly plant based is a real and significant way to protect your cognitive health and your future life. This type of food plan is shown to enhance brain function, protect memory and cognitive abilities…while poor food choices (like processed and ultra-processed foods) can lead to cognitive impairment and decline. Like all of our cells, the brain requires nutrients to keep it working well. Additionally, it is important to realize that inflammation anywhere in the body will also bathe the brain in that same inflammatory chemistry and lead to the destruction of your brain health.

 

“Like an expensive car, your brain functions best when it gets only premium fuel. Eating high-quality foods that contain lots of vitamins, minerals, and antioxidants nourishes the brain and protects it from oxidative stress — the "waste" (free radicals) produced when the body uses oxygen, which can damage cells. Unfortunately, just like an expensive car, your brain can be damaged if you ingest anything other than premium fuel. If substances from "low-premium" fuel (such as what you get from processed or refined foods) get to the brain, it has little ability to get rid of them. Diets high in refined sugars, for example, are harmful to the brain. In addition to worsening your body's regulation of insulin, they also promote inflammation and oxidative stress. Multiple studies have found a correlation between a diet high in refined sugars and impaired brain function — and even a worsening of symptoms of mood disorders, such as depression?”

“Diet, exercise and other aspects of our daily interaction with the environment have the potential to alter our brain health and mental function. We now know that particular nutrients influence cognition by acting on molecular systems or cellular processes that are vital for maintaining cognitive function. This raises the exciting possibility that dietary manipulations are a viable strategy for enhancing cognitive abilities and protecting the brain from damage, promoting repair and counteracting the effects of aging.”

Bottom Line: By constructing a diet high in fiber, polyphenols and other phytonutrients, we give our brain and body what it needs to control and properly manage inflammation. Your future totally depends on what you are doing NOW. What is your future health and cognitive ability worth to you? By making sure that your food choices reflect your values and support your stewardship of your precious Temple, you can create an optimal future and a better present. Good news: patients frequently report that after going 80% into an optimal food plan not only that they feel better but now will notice that when they ‘stray’ into some regrettable choices that they simply do not feel well at all…that they get foggy or down…and these ‘bad’ feelings are so strong and noticeable that eating well becomes a priority. This type of transformation is available to you if you need it…most of us can benefit as well as the planet.

To Avoid Chronic Disease, Watch What You Eat
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.

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.

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)
