The so-called Blood Type Diet was popularized by naturopath Peter D'Adamo in his book "Eat Right 4 Your Type." It's based on D'Adamo's research into anthropology, medical history and genetics, and he contends that you will feel healthier and possibly lose weight by following a diet suited to your blood type. However, MayoClinic.com reports there's no scientific evidence that this diet is more beneficial for weight loss than other diets.
Foods to Eat
D'Adamo contends that people with type-A blood descend from early vegetarian farmers and are more naturally suited to a vegetarian diet. They should focus on foods that are fresh, pure and organic. He contends that people with type-A blood are predisposed to heart disease, cancer and diabetes, and proper diet is critical to their sensitive immune systems. Those who have type-A blood should include plenty of fruits, vegetables, grains, beans, legumes, nuts and seeds in their diets.
Foods to Avoid
Knowing what foods not to eat is another important aspect of The Blood Type Diet. If you have type-A blood, D'Adamo says there are a number of foods you should avoid. Stay away from dairy products and high-protein foods such as meat, fish, poultry and eggs. You should also avoid processed foods.
Exercise
A third component of The Blood Type Diet is exercise. Just as blood type determines which foods you should eat, D'Adamo contends that it also determines the type of exercise that is best for you. If you're a Type A, D'Adamo says your body is best suited to calming exercises. Consider taking up an activity such as golf, yoga or tai chi.
Typical Menu
A typical menu for a person with type-A blood might include a breakfast of oatmeal with soy milk, grapefruit juice and coffee. Lunch may consist of a Greek salad, apple, sprouted wheat bread and herbal tea. A typical dinner might be tofu pesto lasagna and broccoli. Try fruits and rice cakes with peanut butter for a snack.
Warnings
There's a lack of solid scientific research to back the claims made by The Blood Type Diet. People may lose weight on the plan, but it could be simply because they're following a healthier diet and cutting out highly processed, high-calorie foods. Because the type A diet is very restrictive, you may not be getting all the vitamins, minerals and other nutrients you need. D'Adamo recommends supplements to make up for what you're missing, but most people should be able to get the nutrients they need by following a healthy diet.
