I became interested in the Blood Type Diet when I read (and saw, experimentally with my friends) that most autistic/vaccine damaged kids are Type A, which is also prone to inflammatory autoimmune diseases, of which I, as a TypeA-er, have. In addition the broad outlines: eat less meat, more vegetarian; avoid scary/violent movies and crowds; don't sunbathe...plus a bunch of other things were already things I didn't like to do (e.g., have been a vegetarian for a long time, never been crazy about meat, HATE and cannot watch violent movies), so I'm trying this diet that suggests foods that are good and bad for you.
For instance, since type As don't produce enough HCL in the stomach, digestion-friendly foods like a glass of red wine and a cup of coffee actually can be beneficial. Whoopee! My chiro's office even had a good on Blood Type Diet and FERTILITY. Will check that out, and check back for updates.
