Could eating a diet based on your blood type -- O, A, B, or AB -- help you lose weight and get healthier? That's the idea behind the Blood Type Diet, created by Canadian naturopath Peter J. D'Adamo. D'Adamo claims that the foods you eat react chemically with your blood type. If you follow a diet designed for your blood type, your body will digest food more efficiently. You'll lose weight, have more energy, and help prevent disease. There is lots of controversy around this theory but it does work for a lot of people, so could it work for you? What You Can Eat... Depends on your blood type. Here's what D'Adamo recommends for each type: Type O: A high-protein, low carb diet heavy on lean meat, poultry, fish, and vegetables, and foods to avoid include dairy products, beans, cereals, bread, pasta and rice. Oats, corn and wheat are particularly troublesome for O’s. This blood type can have lots of healthy fats like olive oil. Type A: A meat-free diet based on fruits and vegetables, beans and legumes, and whole grains -- ideally, organic and fresh, because D'Adamo says people with type A blood have a sensitive immune system. Of all the blood types A’s usually thrive on a vegetarian diet but should still avoid dairy. Type B: Only one person in 10 has blood type B – a real shame when you consider this blood group has the least dietary restrictions! Avoid corn, wheat, buckwheat, lentils, tomatoes, peanuts, and sesame seeds. Chicken can be a problem for B’s. He encourages eating green vegetables, eggs, certain meats, and low-fat dairy. Type AB: AB’s do best on a mixed diet with an emphasis on vegetables. AB’s should follow a veggie diet most of the time with some meat, fish and dairy products occasionally. D’Adamo says people with type AB blood tend to have low stomach acid and should avoid caffeine, alcohol, and smoked or cured meats. Have you tried to Eat Right for Your Blood Type?
