Blood type diets were introduced by Peter D’Adamo in his book “Eat Right for Your Type” which was first published in 1996. This new diet plans which solely focused on what to eat and what not to depending on your blood type. He claimed that human well-being depends on following blood type diets.
He was also certain that people may also maintain their required body weight and following these blood specific diets will also help prevent diseases. The theory behind his research on blood type related diets was that the ability to digest food was linked with the blood type.
Eating according to your blood type will help digest certain foods which will enhance the digestion process, hence it will be easier to maintain an ideal weight, prevent diseases such as cardiovascular issues and cancer. These diets may also be helpful in increasing energy levels.
It was said that blood type O was the original blood type of the earliest humans. Their diets mainly revolved around animal protein as they were hunter-gatherers. Blood type B was common among nomadic tribes who had more dairy products in their diets. Type A was known to evolve when humans started farming vegetables so their diets were high on vegetables. Lastly, blood type AB was evolved when people with type A and type B started intermingling.
Eat according to Your Type
The book allocated certain foods to every blood type, depending on what is best for their digestive system. It claimed that people should strictly follow these guidelines if they want to lead healthier lifestyles, have increased energy levels, maintain an ideal body weight and prevent diseases.
There is no distinction between negative or positive blood types. The diets are the same for both negative and positive types for one specific blood group. Types of exercises and workouts are also recommended for each blood type.
Blood Type O
People with blood type O are recommended to eat high protein foods. They should increase their intake of meat and fish, and also include vegetables and fruits in moderate amounts. Olive oil, broccoli, seafood, spinach, and red meat are best when trying to lose weight. However, dairy products, corn, and wheat should be avoided.
Blood Type A
People with type A blood group should focus on eating fruits, vegetables, whole grains, seafood, tofu, and turkey. Dairy products, corn, wheat, kidney beans should be avoided. If looking to lose weight then vegetables, olive oil, seafood, and soy should be included in your diet plan. Red meat should be avoided.
Blood Type AB
Chicken, corn, and beans should be excluded from the diets of people with AB blood type. Dairy products, lamb, fruits, vegetables, fish, grains, and tofu should be a part of a diet for AB blood type people.
Blood type B
The lectins (protein in food) that are compatible and react well with blood type B include a variety of foods like fruits, eggs, vegetables, meat, and dairy products. They should avoid chicken, wheat, corn, lentils, tomatoes, peanuts, and sesame seeds.
Most of the leafy green vegetables, broccoli, cabbage, Brussel sprouts, cauliflower, carrots, hot peppers, mushrooms, bananas, grapes, apricots, mango, pineapple, berries, papaya, apples, pear, and peaches are all the fruits and vegetables that are allowed in type B diet.
Efficacy of Blood type Diet
These extensive guidelines provided by the naturopathic physician have been studied thoroughly. In 2013, a study showed that there is no link between the digestions of certain foods and blood types. Certain blood type diets are a healthier option and also showed a decrease in cholesterol, blood pressure, weight loss, and other cardiovascular diseases but they were not restricted to blood types.
People having different blood group also had the same effect as the people who had the same blood type for which the diet was designed. Following these diets may help you have a nutritionally balanced diet and provide health benefits.
