I subscribe to Science Daily, and at a minimum, I check out the headlines for the results of studies in the almost-daily emails they send me. I follow up on a few, reading the plain-language synopses of scientific studies that may be over my head in terms of using “science-use”.
This one caught my eye: Nutrients in blood linked to better brain connectivity, cognition in older adults.
Many of my friends and integrative bodywork clients are 60+. I myself take supplements and try to eat a healthy balanced diet. I was curious: Am I getting the right nutrients to nourish my brain?
The article cites a study that shows that higher levels of specific nutrients is robustly linked with higher brain connectivity and performance on cognitive tests in older adults. They looked at 32 nutrients in 116 healthy adults age 65-75. They also invited 40 participants back after two years and got the same results.
Rather than surveying participants on their diets, they looked at biomarkers in the blood. This would show what’s actually being absorbed.
They also used fMRI technology to look at how local and global brain networks performed, to see how many steps it took to complete a task on several cognitive tests.
This appears to be a very robust study.
What they found is that indeed, several nutrients are linked with higher brain performance. The nutrients are:
- omega 3 fatty acids (found in salmon, sardines, walnuts, flaxseed, hempseed, avocados and more — amount should be higher than omega 6)
- omega 6 fatty acids (found in flaxseed, hempseed, pumpkin seeds, sunflower seeds, and nuts)
- carotenoids (found in red, orange, and yellow vegetables and fruit)
- lycopene (a carotenoid found in red tomatoes, watermelon, grapefruit, and papayas)
- riboflavin (Vitamin B2, found in eggs, organ meats, lean meats, mushrooms, spinach)
- folate (Vitamin B9, found in dark green vegetables, dried legumes, eggs, beets, citrus)
- Vitamin B12 (found in organ meats, clams, sardines, fortified nutritional yeast, other fortified foods)
- Vitamin D (found in sunlight on the skin and supplements — no foods contain enough to prevent deficiency)
The researchers found that higher levels of omega 3s in particular boosted the functioning of the frontoparietal network, which supports the ability to focus attention and engage in goal-directed behavior.
My take is to eat nutrient-dense foods every day for every meal. I eat wild salmon (it can be canned) or sardines several times a week, keep nuts on hand for snacking, eat the healthiest eggs I can get at least once a week, buy large bags of baby spinach and broccoli at Costco, enjoy fresh-squeezed grapefruit juice and watermelon in season, make a delicious chicken-liver paté, and eat dried beans almost daily. I cook with olive, avocado, ghee, and coconut oil.
Also, take note of what foods are not listed. What are some shifts you could make to improve your brain health?
I also supplement with Vitamin D and a methylated B complex. If you have had genetic testing that shows you have an MTHFR mutation (which I do), when you buy Vitamin B supplements, be sure the label says folate instead of folic acid and methylcobalamin (B12) instead of cyanocobalamin. If you don’t know if you have an MTHFR mutation, get these methylated versions of these nutrients because it’s estimated that 60 percent of Americans do have a mutation.
