I skimmed through a book called "Eat Right 4 Your Type" by Peter D'Adamo and Catherine Whitney that says different blood types have different antigens that affect the digestibility of various foods.
I'm blood type A, and the book says milk and OJ greatly elevate serotonin and impair digestion for my blood type.
I switched to getting a major part of my calories from white rice, blueberries, and feta cheese instead of milk + OJ for the past few days and noticed a major deepening of my voice and improved digestion. I think the switch might have lowered serotonin and caused my androgens to go up. I drank a lot of OJ again today and my digestion is noticeably worse. So I think there is definitely something to this.
Substituting feta cheese for milk seems like it will work in the long-run, but rice has a lot of arsenic and iron, and I did feel a negative impact from the PUFA in blueberry seeds because of the massive quantity I had to eat to get enough carbs, so I still have to work out the optimal carb source for me (grape juice and guava juice seem to be OK for type A, but grape juice is high reservatrol which Dr. Peat doesn't like, and guava juice is a bit hard to find). Still wanted to share my experience so far though with eating according to my blood type.
