Back in 1994, I had this figured out, that food was hugely important for mental health and I've been on a decades long search for the right diet. I did best when we raised all our own food. I ate NO sweeteners of any kind in the beginning. In 2006 I cut out wheat of any type. I lost weight. Currently I am on keto and intermittent fasting. But I'm finding it hard to do. So I am curious and have ordered the book from the library. I am always fascinated by the science and am fully aware of how very little is taught about nutrition in medical schools.
