Blood Type O Diet Foods

Dr. Peter D'Amado, a naturopathic doctor, formulated a diet to help people lose weight. The foods recommended depend on the person's blood type. Dr. D'Amado found that people with type O blood tend to do best when they have plenty of opportunities for vigorous exercise and when they eat high levels of protein. Dr. D'Amado has made available a list of foods in each food group that are appropriate for people with type O blood.

Meats

People with type O blood should eat a variety of meats. All types of lean red meats, including mutton and veal, are appropriate, as well as all forms of poultry, except for goose. Pork should be avoided. Most types of fish are also good for type O's, though they should avoid catfish, caviar, lox, pickled herring and octopus.

Dairy Products

Type O's should eat limited dairy products. Type O's who are African American should not eat any milk or egg products at all. Others should eat only organic, free-range eggs. Goat milk and feta cheese are good choices, and mozzarella is allowed occasionally. All other dairy products should be avoided most of the time. Clarified butter is an allowed choice for cooking.

Grains

Because those with type O blood tend to fare better with high-protein diets, corn, oats, and wheat products are to be avoided. Kidney and navy beans, as well as lentils also tend to cause weight gain in type O's. Grains in the type O diet should include barley, buckwheat, quinoa, rye, spelt and rice.

Fruits and Vegetables

Produce should be either grown in your own garden, or purchased locally. Organic is always best. The best fruits for type O's include figs, plums and prunes. Avoid coconuts, oranges, tangerines, melons and plantains. The best vegetables include kale, kelp and spinach. Avoid cauliflower, Brussels sprouts, avocados, mushrooms, olives and potatoes.
