Research conducted at the University of Kentucky College of Medicine suggests that higher intake of specific nutrients is associated with lower brain iron concentration and better cognitive performance in older adults.
The study was recently published in the Neurobiology of Aging and highlights the important balance of non-heme iron for optimal neuronal function. Excess non-heme brain iron has been associated with neurological diseases such as multiple sclerosis and Alzheimer's disease. High levels of brain iron can also be seen in normal aging, where they have been correlated with poor cognitive performance.
A key question is whether age-related increases in brain iron and related cognitive declines can be slowed by environmental factors, such as healthy dietary intake. To explore this question, the research team evaluated the relationship between nutritional intake, brain iron and cognitive performance in a group of healthy, older adults between 61 and 86 years old.
The team was able to address the question using a variety of methods including computer assessments to quantify working memory performance, questionnaires to obtain nutrition information and an in vivo MRI technique called quantitative susceptibility mapping to measure iron concentration in brain tissue.
Consistent with previously published work, the results indicated that increasing age was associated with higher levels of brain iron concentration and poorer working memory performance. However, those older adults with high dietary intake of nutrients commonly found in nuts, soybeans, olive oils, and fish (such as vitamin E, lysine, DHA omega-3 and LA omega-6 PUFA) tended to have lower brain iron and better working memory performance than expected for their age.

so eating well is good for you? who knew!
Based on this study, I would not take iron without taking vitamin E at the same time.
Well, I’m screwed. I don’t eat fish (or seafood, shell fish, etc.). I also don’t think green tea (brewed black tea iced, yes).
think -> drink
Brain Iron? What about those with a High Content of Iron naturally?? How about someone with enough Iron or something in thier blood that an MRI literally sucked the blood right out of thier veins while making them glow for over a month, as if they had Magnetic Blood already??, and then left trails of dried blood(bruising) following all veins lasting 3 years plus?
IOW, diets not normally served in residential care settings.
Nutrition bump
Excess iron is very hard on the body. Adult men and post-menopausal women should consider donating blood once or twice a year in order to rid the body of excess iron. (Our ancient ancestors didn’t have this problem due to injury and esp. parasites.) Have you ever seen a person — usually a man — with an unnaturally ruddy complexion? His system is overloaded with iron.
Supplements can suffice and consider finding a white tea you can enjoy, as white tea has 60% of the EGCG that green has, plus it has other antioxidants green tea does not.
This is doable!
My system doesn’t seem to react well to the caffeine in green tea so I’ll just take a green tea pill. I’ll remember the white tea next time I go shopping.

I suggest once every two years.
With a blood test, you would know whether you can remove more blood without causing a deficiency. If ferritin is less than 70 ng/ml, the person is deficient in iron.
Is the best source of LA omega-6 PUFA—olive oil and say, avacado oil.
Also is it your impression that the major health benefits of olive oil are due to the polyphenols in the olive oil rather than its other ingredients.
I believe most of the benefit of olive oil is in its squalene and other antioxidants and in its high monounsaturated fats as a replacement for an oil super heavy in Omega-6 fats.
Is the best source of LA omega-6 PUFA—olive oil and say, avacado oil.
The main fat in olive oil is omega 9.
Every food has omega 6 fats. Everybody has more omega 6 fats than they need.
Peole started using a lot of seed oil in the 20th century. Seed oils are the highest source of omega 6 fats. The percentage of fats that is omega 6 fats in people’s bodies has been increasing and keeps increasing. People today have more omega 6 fats in their bodies than at any point in history.
I looked for recommended doses but didn’t find any. Have you seen any recommended doses for the various supplements mentioned in the article.
I typically take about 3 grams of the omega 3 fish oils. But that’s just to keep my omega 3-6 ratios between 1-2 to 1.
A lot of the science of fats is fradulent to sell seed oils and fish fat. In Spain, where they produce olive oil, people are terrorized by butter.
