Soy proteins and their derivatives contain processed free glutamic acid. Soy should be avoided due to this problem.

Even though your diet looks good, the available B vitamins is likely lacking. In my experience, I need 10 times to 50 times the RDA of B's. This is hard to get from normal foods. Supplements are needed. A whole egg or two on a regular basis can help with these brain needs. The yolk has important nutrition in it. Also good for cholesterol.
