According to Dr. Michael Lam, chemical reactions occur between the foods you eat and your blood type. These occurrences are caused by proteins called lectins. When you eat foods that are not beneficial for your blood type, these lectins target bodily organs or other areas and cause the blood cells in these areas to clump together and cause disease. Dr. Lam believes that everyone should eat a blood-type-specific diet that will protect their blood cells from uncomplimentary food attacks.
Type O
People with type O blood flourish on a high-protein diet because they digest meat easily. The most beneficial meats for type O blood types are lamb, beef, venison, mutton and veal. However, type O blood types should not consume pork or goose. The most beneficial fish for type O blood types are herring, mackerel and cod, and the least beneficial are catfish, conch, octopus, salmon, barracuda, caviar, octopus and pickled herring.
Type O blood types should severely restrict eggs and dairy products and should not eat many whole-wheat products because they are not well tolerated by this blood type. People with type O blood should eat collard greens, garlic, spinach, artichokes, red peppers, sweet potatoes, romaine lettuce and figs, plums and prunes to support optimal health.
Type A
Type A blood types should not eat meat because they naturally have a low stomach-acid content that cannot digest land animal meats. However, type A blood types can eat seafood such as yellow perch, red snapper, monkfish, salmon, carp, group, mackerel, silver perch, snails and rainbow trout. Type A blood types cannot easily digest dairy products but can consume goat milk and cheese, yogurt, mozzarella, kefir, ricotta and feta cheeses. Type A blood types can digest cereals, grains and pastas well and should eat an abundance of fresh, organic vegetables including alfalfa sprouts, romaine lettuce, Swiss chard, dandelion greens, artichokes, turnips and okra. Type A blood types should eat a wide variety of fruits including plums, blackberries, cranberries, figs and prunes.
