Blood Type A - Tend to be cooperative, sensitive, clever, passionate and smart. Often bottling up anxiety in order to get along with others, they may hold in their emotions until they explode. Many are tense, impatient and unable to sleep well. While they are capable of leadership positions, they may not take them because the stress is not good for their tightly wired systems. In Japan many “A”’s are in research. They have roles in discovering more about and refining science, economics, manufacturing, etc. Their research on microflora and other areas of medicine is some of the best and most meticulous in the world. They are perfectionists to say the least. This quality shows up in their perfecting electronics like TV’s and also less expensive more efficient cars that were originally created here in the US.

Blood type A’s tend to have more sensitive constitutions. Too much stress weakens their immunity more quickly than other blood types. Low stomach acid is common among blood type A’s even from birth, so special care should be taken when eating animal proteins. Using digestive enzymes, like Assist Dairy and Protein, along with consuming fermented foods and drinks is really a must for A’s. It is not surprising to me that fermented foods like Miso and Natto play an important role in providing easily digested protein, in the Japanese Diet. They also eat raw fish which is much easier to digest than cooked.

Blood Type B - Blood type B individuals tend to be balanced: thoughtful like A’s and yet ambitious like O’s. They are empathetic, easily understanding others’ points of view, yet often hesitating to challenge or confront. Chameleon-like and flexible, they make good friends.

Blood Type AB - Tend to be very charming and popular. They don’t sweat the small stuff and can be seen as spiritual and even at times a bit “flaky”. Only about 2 - 5% of the population are blood type AB. There is never a dull moment in a AB’s life, so if you find one for a friend, consider yourself lucky! Youll enjoy some exciting times together!

Like blood type A’s, AB’s react to stress poorly. They are stronger and more active than type A’s, but need to pay attention to stress levels so that they don’t compromise their immunity.

Sometimes it is difficult to be an AB. AB’s don’t like to fit in anyone else’s “boxes”. If they feel too confined, they’ll break out of that box and do things their own way. When it comes to food choices and AB must discover when they are more B-like or A-like. For example, dairy foods like milk kefir can be excellent for them or not good at all.

Blood Type O - Tend to be loners or leaders and are intuitive, focused, self-reliant and daring. They handle stress better than other blood types and have strong immune systems, a well developed physique and a physically active nature. Blood type O’s tend to have sluggish blood flow and feel better with vigorous exercise for about an hour each day. [Source]
