If you are afraid of Alzheimers, the gingko will help, and being on this diet has been shown to not correlate with getting it (i.e eating higher fats doesn't lead to it). They are begining to think that blocked arteries may contribute to getting it, so this diet would help with that, judging by recent research as well as taking Folic acid and Vit B6and 12 for keeping homocysteine down. Be sure to get rid of the free radicals that might also contribute, they think, so take lots of Omega 3's (flaxseed oil and fish oil...I take both) and Vit E. Keep your brain active e.g. doing crossword puzzles, that sort of thing. And exercise to oxygenate.
