Blood Type A

People with Blood Type A evolved from the hunter/meat-eater to the agrarian, and were the farmers and grain gatherers. This blood type evolved between 25,000 and 15,000 bC. They have fragile digestive systems. These people cannot tolerate animal protein well, and should be the proverbial, classic "vegetarian" of the human species. They also are usually lactose intolerant, as well. Persons with Blood Type A should avoid animal protein and dairy products, and would do well with whole grains, legumes, fruits and vegetables. Tofu and Hawaiian Spirulina should become the Blood Type A person's best friends, as these foods contains high-quality vegetable protein! Persons with Blood Type A do not produce enough hydrochloric acid in their stomachs, and that is why they have a difficult time digesting animal protein well. This also gives them a predisposition toward getting stomach cancer, and should never eat smoked or cured meats due to the sodium nitrites in them. Animal protein and dairy products tend to rot and ferment in their digestive tracts, and the toxic bacteria backs up into their tissues and muscles, thereby causing digestive distress. A lack of sufficient hydrochloric acid in their stomachs is another reason that persons with Blood Type A do not absorb Vitamin B12 properly from the foods they eat. Vitamin B12 is normally found in red meat, although B12 is also found in superior vegetable protein foods such as Hawaiian Spirulina, soy products and sea kelp. This inability to absorb Vitamin B12 sufficiently from food tends to make the person with Blood Type A prone to pernicious anemia. Therefore, supplementing the diet with Vitamin B12 is critical. Also recommended is supplementation with digestive enzymes such as betaine, bromelain and papain. Bromelain is derived from pineapple, and assists with the digestion of animal protein. Betaine will help to increase the amount of hydrochloric acid in their stomachs. The best exercise for these persons is not the heavy, vigorous workouts, but more calming, centering exercises like Tai Chi, Hatha Yoga and golfing. These soothing types of exercises will relieve the Blood Type A person's stress in a more beneficial way.

If you believe any of the information provided in the previous answer, I have a bridge in Arizona I would like to sell you for practically nothing. If you had the capability, you would discover that millions and millions of people who apparently don't know any better violate every one of the rules in the previoius answer and suffer absolutely no ill effects at all.

Believing in dietary regimens based on blood type is even more fringe than believing in astrology. Heck, forget the bridge, I have a surefire investment where you can triple your money in two weeks. All I need from you is $100,000.
