The ‘Eat Right For Your Blood Type’ diet

What is it?

The Eat Right for Your Type diet encourages people to eat certain foods and avoid others based on their blood type: A, B, AB or O.

Celebrities who've tried this approach are said to include Cheryl Cole, Sir Cliff Richard and Courtney Cox-Arquette.

Peter D'Adamo, a naturopathic doctor and the author of Eat Right for Your Type: The Individualized Diet Solution to Staying Healthy, Living Longer & Achieving Your Ideal Weight, believes blood types affect the digestive system and that some foods good for people of one type are "dangerous" for another.

It goes further than that for Dr D'Adamo, who believes that your blood type also determines your susceptibility to certain illnesses and how you should exercise.

Critics cite a lack of published evidence backing Dr D'Adamo's blood type-based diet plan.

This diet may suit those enthusiastic about a plan that doesn't involve tracking calories or fat grams, while others may find it difficult to stay within the diet's confines, a challenge made greater if more than one person in a household follows the diet -- and has a different blood type.

What you can eat on this diet

What you can eat -- and how you exercise -- on this diet depends on who you are.

If you're blood type O (for “old", as in humanity's oldest blood line) your digestive tract retains the memory of ancient times, says Dr D'Adamo, so your metabolism will benefit from lean meats, poultry and fish. You're advised to restrict grains, breads and pulses, and to enjoy vigorous exercise.

Type A (for “agrarian") flourishes on vegetarian diets, "the inheritance of their more settled and less warlike farmer ancestors," says Dr D'Adamo. The type A diet contains soya proteins, grains and organic vegetables and encourages gentle exercise.

The nomadic blood type B has a tolerant digestive system and can enjoy low-fat dairy, meat and produce but, among other things, should avoid wheat, sweet corn and lentils, Dr D'Adamo says. If you're type B, it's recommended you exercise moderately.

The "modern" blood type AB has a sensitive digestive tract and should avoid chicken, beef and pork but enjoy seafood, tofu, dairy and most produce. The fitness regimen for ABs is calming exercises.
