If you have type A blood and suffer from diabetes, hypothyroidism, obsessive-compulsive disorder or are overweight, naturopath Peter D’Adamo says that you’re probably eating foods that aren’t compatible with your blood type. In his book, “Eat Right 4 Your Type,” D’Adamo claims that people with type A blood are descended from ancient Asian and Middle Eastern farmers. By following a diet that mirrors what their ancestors ate, D’Adamo says type A individuals will be healthier and thinner.
The Blood Type diet is criticized by most health experts, including Mayo Clinic nutritionist Katherine Zeratsky, who says the plan is not based on scientific evidence and encourages followers to eliminate nutritious foods from their diet. Talk to your doctor before starting the Blood Type diet.
Meat, Poultry and Seafood
D’Adamo recommends that people with type A blood eat plenty of fish, including salmon, sea or rainbow trout, red snapper, cod and mackerel. Chicken and poultry can be eaten up to two times a week, but D’Adamo says to avoid all beef, pork, game meats and shellfish.
Dairy Products and Eggs
Type A individuals following the Blood Type diet are instructed to avoid all dairy products and eggs. If you need a substitute, use rice or soy milk. Some type A people may be able to occasionally eat yogurt, goat cheese or kefir without experiencing health problems, says D’Adamo.
Fruits and Vegetables
Type A individuals should eat a wide variety of fresh, organic fruits and vegetables since, according to the theory behind the Blood Type diet, these are what their ancestors primarily ate. The best vegetable choices include artichokes, onions, broccoli, okra, turnips and dark leafy greens like spinach, kale, collard greens and escarole. Blueberries, cherries, figs, pineapple, plums and grapefruit are the best fruits. Type A people are told they can have asparagus, cucumbers, avocados, beets, strawberries and apples a few times weekly, but should avoid bananas, oranges, cabbage, eggplant, tomatoes and potatoes.
According to the Blood Type diet guidelines, the most beneficial grains for people with type A blood include sprouted wheat, cereals like kasha, buckwheat or amaranth and rice, oat or rye flour. All types of white or wheat flour should be avoided, along with semolina pasta. Rice, barley, corn, couscous, quinoa and millet are fine to eat one or two times a week.
Nuts, Seeds, Beans and Legumes
Pumpkin seeds and peanuts are good for blood type A individuals, says D’Adamo, as are beans and legumes like lentils, black-eyed peas, red soybeans, black beans and pinto beans. Type A people are warned to avoid pistachios, cashews and beans such as navy, red, garbanzo or kidney beans.
Fats and Seasonings
People with type A blood are advised to use olive and flaxseed oil for eating and cooking, though cod liver and canola oil can also be used occasionally. Soy sauce, miso, ginger, garlic, mustard and tamari are considered beneficial seasonings. Pickles, salad dressing and jams or jellies prepared from acceptable fruits are fine in moderation, but type A people are instructed to avoid all vinegar, ketchup, mayonnaise and pepper as well as corn, peanut, sesame and safflower oils.
