Type A? Suggestion...look up on line or get the book " Blood Type Diet " eat only Highly Beneficial foods, pick 2-3 see if you feel better. If yes stay on them. Out of all the things suggested and tried, SCD yogurt is amazing! Most current health tip I'm following, at least a cup a day. There are specific instructions to get it "right" (or correct):) not too hard for me to do with serious brain fog going on though... look at SCD 24hr yogurt
Book "Eating Alive 2" is helping me understand all this a lot more...Ileo-cecal valve
...also lots of distilled or R/O water always... hope this helps : )
