Here's how to eat right, depending on your blood type

Have your heard about the Blood Type Diet? It is based on the principal that chemical reactions happen between the food that we eat and our blood. This reaction is caused by lectins – proteins found naturally in food – that can cause blood cells to clump together. Certain lectins are thought to be incompatible with certain blood types, which causes them to target bodily systems or particular organs and cause adverse reactions.

Although immune systems protect from most lectins, a small percentage still ends up in the bloodstream. Proponents of the Blood Type Diet encourage people to remove certain foods or food groups from their diet because of the lectins they contain. Although there is some contention about the accuracy of this theory, most people agree that the diets themselves are relatively healthy and harmless, so why not give them a go? Find your blood type below for more information.

Blood Type A

People in this group are suited to a largely vegetarian diet, according to Body and Soul, and should focus on fresh, organic foods. This group is predisposed to heart disease, cancer and diabetes, and is best suited to calming exercises such as yoga or golf.

Blood Type B

If you're in this group, you're lucky: Those with blood type B have strong immune systems and relatively tolerant digestive systems, so they can eat most foods. According to Body and Soul, B's tend to resist many degenerative illnesses and are well-equipped for more strenuous exercise such as cycling and swimming. Livestrong adds that it doesn't matter if you're B+ or B-, your diet should be well balanced between meat and vegetables. The most beneficial meats are lamb, goat, rabbit, mutton and venison, whereas chicken isn't so good. Foods to avoid, such as wheat, buckwheat, corn, lentils, peanuts, sesame seeds and tomatoes, can compromise the B blood type group's metabolism and can cause fluid retention, fatigue and hypoglycemia.

Blood Type AB

WebMD recommends that this group choose foods such as tofu, seafood, diary and green vegetables. People with type AB blood tend to have low stomach acids and should avoid caffeine, alcohol and cured meats. Body and Soul adds that this group tend to have the fewest problems with allergies but heart disease and anaemia are an issue.

Blood Type O

This group is the most suited to animal proteins, as well as the most strenuous physical exercise such as running. O's should consider avoiding dairy products and grains, and can be prone to developing asthma and other allergies, as well as arthritis, according to Body and Soul. Authority Nutrition notes that this closely resembles the paleo diet: heavy on meat, fish, poultry and vegetables but limited in grains, legumes and dairy.

It is important to note that these suggestions are not weight-loss diets. Instead, they're structured for optimum gut and full-body health, based on genetics. Regardless, they all consist of healthy foods and, when followed properly, none should be harmful. Before starting a new diet, though, you may want to check with your doctor.

Remember that any sudden dietary changes may cause some gastrointestinal changes or fluctuations in energy in the short term as your body adjusts, so persevere for a month or so and then reassess. See Dr. D'Adamo's official website for a detailed description of the strengths, weaknesses and genetic predispositions of each blood type.
