Melons, cantaloupe, honeydew
These fruits are high in acid content which may irritate the acidic stomach of Type Os

Type As 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 as you eliminate the toxic foods from your diet. And when you follow the Type diet, you can supercharge your immune system and potentially short-circuit the development of life-threatening diseases.
When Type As eat meat, they experience sluggishness. Type As have low stomach-acid content, therefore they have a hard time digesting meat. 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, which may cause obesity and diabetes. 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.
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 are not good for your digestive tract.
