Individuals with blood type A flourish on vegetarian diets. Type As are predisposed to heart disease, cancer, and diabetes. It is particularly important for sensitive Type As to get their foods in as natural a state as possible: fresh, pure, and organic. When you get on the Type A Diet, you will naturally be thinner. If you are accustomed to eating meat, you'll lose weight rather rapidly in the beginning. Eliminating some of the toxic elements of meat from your diet greatly helps out the detoxification process in your body; and when you follow the Type diet, you can supercharge your immune system and potentially short-circuit the development of life-threatening diseases. This helps reduce the burden on the stress response systems of the body, curtailing and preventing symptoms of a dysfunctional NeuroEndoMetabolic (NEM) stress response.
When Type As eat meat, they experience sluggishness. Type As have low stomach-acid content, therefore they have a hard time digesting meat. The slow and sometimes incomplete digestion generates a greater toxic load as microscopic organisms grow within the gut that are normally kept in check by a healthy gut microbiome. Reducing or eliminating meat from your diet prevents this increased toxic load from affecting your body’s detoxification process, an important circuit of the NEM stress response system.
This Since Type As eat very little animal protein, nuts and seeds supply an important protein component. Type As also thrive on the vegetable proteins found in beans and legumes, except those mentioned for the "Avoid" list. These beans can cause a decrease in insulin production, creating an imbalance in your body’s metabolic processes that generates stress, and which may cause obesity and diabetes over a long period of time. Tofu should be a staple in the Type A Diet.
Dairy foods are also poorly digested by Type As, and can cause metabolic slowdown. Type As can tolerate small amounts of fermented dairy products such as yogurt, kefir, nonfat sour cream, and cultured dairy products. The fermentation process breaks down and converts many of the offending and difficult to digest proteins and nutrients into forms which cause less stress, eliminating some of the load on the NEM stress response to make sure the body continues to run smoothly.
Vegetables are vital to the Type A Diet, providing minerals, enzymes and antioxidants. Type A are very sensitive to the lectins in potatoes, sweet potatoes, yams, cabbage, tomatoes and peppers. They aggravate the delicate stomach of Type A. Type A should eat more fruits that are alkaline, avoid mangoes, papaya and oranges for they cause extra stress to your digestive tract create imbalances in the metabolic circuits of the NEM stress response.
