EXCELLENT point. My memory and learning ability is always HEIGHTENED whenever I eat healthier. Sometimes I can simply read something just one time over and remember ALL of it. I was diagnosed with disorganized schizophrenia for quite some time. Subsequently, I received a diagnosis of paranoid schizophrenia. Now, whenever I see my psych doc for a checkup, he just simply writes "f.20" which is classified as "miscellaneous". I have an excellent memory, if I choose to have one. Diet also plays an integral role in overall cognitive functioning and peak performance. In particular, choline and methylcobalamin, found in meats, are great cognitive enhancers. The methylcobalamin, along with methyltetrahydrofolate and methionine, are excellent chelators for heavy metals like Aluminum and Silicon in the form of tetrahedral zeolites oxidized with O2. Thallium is another metal to be weary of. Choline is great for memory retention. In particular, Choline Bitartrate is a good supplemental form. It works in conjunction with Acetyl-L-Carnitine and glycerylphosphorylcholine. These two are precursors to the former. Anyway, the Choline restores CNS levels due to peripheral depletion of choline. To sum up, B12 and choline are both cognitive enhancing B complex vitamins crucial for cognition. Make sure you get plenty of those two from your diet. Another critical aspect in dietetics is making sure you are eating plenty of GREENS. Those are paramount.
