Type A’s unique traits

  • Low stomach acid production
  • Digests carbohydrates efficiently
  • Usually lactose intolerant
Type A’s flourish on vegetarian diets and should avoid animal protein and dairy. Type A’s do not produce enough hydrochloric acid in their stomachs and have a difficult time digesting animal protein, which predisposes them to stomach cancer. Avoid 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 the tissues and muscles, causing digestive distress.

Supplementing the type A diet with Vitamin B12 and iron is critical. Insufficient hydrochloric acid in type A’s stomachs can disturb the absorption of Vitamin B12, leaving type A’s prone to pernicious anemia. Vitamin B12 is normally found in red meat but also is found in high-quality vegetable protein foods such as Hawaiian Spirulina, soy products, and sea kelp.

Supplement with digestive enzymes—betaine, bromelain, papain. Bromelain—derived from pineapple—assists with digestion of animal protein. Betaine helps increase hydrochloric acid.

Calming, centering exercises like ai-chi , tai chi, yoga/yoga in water, Pilates/Pilates in water, and swimming will relieve Type A’s stress in a more beneficial way.
