Recommended Dairy & Eggs for Blood Type A

Small amounts of fermented dairy products are OK. Use soy as an alternative to cow’s whole milk products.


Type A’s can tolerate small amounts of fermented dairy products, but should avoid products made with whole milk, and limit egg consumption to occasional organically produced eggs. Most dairy products are indigestible for type A’s because type A blood creates antibodies to the primary sugar in whole milk. Since the type A immune system is designed to reject anything B-like, the antibodies it creates will reject whole milk products. Many type A individuals have some degree of lactose intolerance, due to insufficient levels of lactase, an enzyme that catalyzes hydrolysis of lactose into glucose and galactose. Eating or drinking dairy products causes problems like cramping, bloating, gas, and diarrhea.

Type A’s normally produce more mucus than other blood types, probably because they need the extra protection it provides their immune systems. Excess mucus can be harmful, since various bacteria can live off it, and an overabundance of mucus leads to allergic responses, infections, and respiratory problems.
