What to eat according to your blood type

Naturopathic physician Peter J. D'Adamo has devised a diet based on the four blood groups. Not only does it offer advice on what food we should eat according to our blood group, it also provides information on what activities we should do. This slideshow will run through the doctor’s tips for each blood group and then leave you to decide whether you agree with his advice.

The basics

One of the main points of alternative medicine is to recognise the individual biochemistry of each person and the need to provide treatments accordingly. Peter J. D’Adamo argues in his books that "there (has) to be a reason why there (are) so many paradoxes in dietary studies and disease survival." For example, why do some people lose weight and others do not while on the same diet, or why do some maintain their vitality in old age and others do not.

Blood types

His research on anthropology, medical history and genetics led Dr. D'Adamo to argue that blood type "is the key that unlocks the door to the mysteries of health, disease, longevity, physical vitality and emotional strength." He explains that the practical application of this concept is that we can make informed choices about our dietary plans and exercise.

Type O

Dr. D’Adamo argues that type O is the first blood type and its ancestral prototype was an aggressive predator. He says some of its aspects are essential in modern societies, such as leadership, energy and extroversion. People with this blood type are more likely to suffer negative metabolic effects brought on by lack of exercise, bad diet and overstress than those with other blood types.

Food for Type O

The diet designed by Dr. D'Adamo for this blood group is based on the consumption of lean organic meats, vegetables and fruits. He recommends avoiding wheat and dairy products, which he believes can trigger digestive problems for this particular group. He also advises avoiding caffeine and alcohol.

Type A

According to Dr. D’Adamo, many neurochemical factors within the genetic make-up of blood type O favour a structured, harmonious and rhythmic life that is surrounded by a positive community. He recommends people with this blood type to learn how to manage stress, to do exercise and to cultivate their creativity. He also advises them to not skip meals and establish a consistent daily routine.

Food for type A

According to the creator of this diet, people with type A benefit from following a vegetarian diet. He argues that if they quit eating meat, they will lose weight and have more energy to eliminate toxins from their bodies. He also believes that it is important for this group of people to consume foods that are natural, pure, fresh and organic.

Type B

The doctor’s diet states that people with type B have the genetic potential for great flexibility and the ability to thrive in changing conditions. At the same time, those with type B tend to be highly sensitive to a lack of balance in their life. According to Dr. D'Adamo, a person with type B who lives according to their genetic characteristics will tend to have fewer risk factors to health.

Food for type B

The diet states that the foods that cause a type B person to put on weight are: corn, wheat, lentils, tomatoes, peanuts and sesame seeds. According to its creator, these foods affect the efficiency of the metabolic process, resulting in fatigue, fluid retention, and hypoglycemia. He also recommends replacing chicken with goats’ meat, lamb, rabbit or venison and that they eat green vegetables, eggs and skimmed dairy products.

Type AB

Dr. D’Adamo’s books state that people with the AB blood type tend to be intuitive and spiritual, and have the ability to see beyond the confines of society. They are friendly, passionate and empathetic. He recommends that they cultivate their social nature in favorable environments and avoid highly competitive situations. They should do 45 minutes of aerobic activity at least twice a week, and yoga, stretching or meditation on a daily basis.

Food for type AB

The diet designed by Dr. D’Adamo recommends that people with type AB should focus on eating tofu, fish, seaweed, dairy products and green vegetables if they want to lose weight. Among the best fish for type AB people are the mahi-mahi, salmon, sardines and tuna. He also advises them to avoid smoked and cured meats.

Find the best diet for you

Take into account that the diet proposed by Dr. D'Adamo is only one of many dietary options available and that it has received criticism. Listen to yourself and discover the option that is best suited to your needs.
