He also suggests type Os avoid coffee, as their higher levels of hydrochloric acid could lead to peptic ulcers. The more they work out and the higher the intensity, the better the blood type Os will feel.ĭ’Adamo recommends that you avoid cereals, grains, dairy, legumes, and beans.

This can cause bouts of excessive anger, but dopamine from brisk exercise is an excellent way to counteract it.

Vegetables, in particular, leafy greens like kaleīecause blood type Os digest meat more easily, an entirely vegetarian diet is not advised.ĭ’Adamo advises that alongside a blood type diet, type Os should exercise vigorously.Īerobic exercises like running, cycling, and weight training suit blood type O, as they are potentially more prone to the stressful fight-or-flight response of our hunter ancestors.

Fruits, particularly plums, prunes, and figs.

Meat, particularly lean meat-but not processed like bacon or sausages.

They should limit grains, dairy, beans, and legumes. People with type O blood should focus on a high animal protein diet with vegetables, fish, and fruit. Type Os would have no issues with animal protein lectins, but they might struggle with dairy or grain-based lectins, which are more easily converted into fats and triglycerides and can cause inflammation. In Type Os, this can mean that metabolizing dairy or carbohydrate is difficult. D’Adamo suggests this can cause difficulties if the food is not one your blood is easily able to digest. Lectins are proteins in food that bind to our blood cells and cause a chemical reaction. D’Adamo also says this also increases their ability to heal their digestive tracts. These advantages make them better at digesting animal protein and fat and help them metabolize cholesterol more efficiently. Type Os are able to eat more animal protein that blood types A, B, and AB because they have more hydrochloric acid in their stomach and secrete greater amounts of the intestinal alkaline phosphatase-and a lipoprotein called ApoB48.

However, the idea is popular, and followers say they feel better adapting their diet to their blood type. There’s no medical research that indicates eating an O positive blood type diet or an O negative blood type diet will improve your health. The O blood type diet has no scientific backing. RELATED: Eating for Your Blood Type-B+ & B- Does the O Blood Type Diet Work? His theory suggests that blood type O positive and O negative people have hunter-gatherer digestive systems that handle meat and fish better than carbs, grains, and dairy.

Rarer type B blood types are thought to descend from the ancient nomadic tribes that consumed dairy from their herds. These early type O humans ate a hunter-gatherer diet of animal protein, but as they moved into a society that put down roots and farmed crops, their blood evolved into type A to help them digest carbohydrate, fruits, and vegetables. Type O has been traced back as far as Cro-Magnon man in 40,000 BC (although there is debate over whether type A is the earliest blood type).

He suggests that O was the first blood type. The “Eat Right For Your Type” diet was created by Peter J. The blood type diet is a theory that your blood group reveals the dietary habits of these predecessors. Your blood group is determined by the genes you’ve inherited from your parents, and this stretches right back to your stone-age ancestors. There are eight different blood groups: A, B, AB, and O each group can be either RhD positive or RhD negative. RELATED: What Are the Blood Types Really for? What’s the O Blood Type Diet About? It certainly makes a difference when it comes to transfusions, and studies show some blood groups are more at risk of certain diseases-but there’s also an interesting theory that eating foods compatible with your blood type can make you healthier. Have you ever wondered whether your blood type makes a difference to your health?
