Type O Those belonging to this blood type can eat a high-protein diet, which includes lean meat, poultry, fish, and vegetables. Caffeine, alcohol, and smoked or cured meats should not be eaten. Those with AB type blood have low stomach acid. Even the vegetables they consumed are fundamentally different than the ones we have now, many of which are grown using pesticides and other chemicals that didn’t exist back then.Type AB People of this blood group should have seafood, tofu, dairy, beans, greens and grains but should avoid corn, beef and chicken.
Our ancestors ate almost every part of the animal. Reality: Is actually possible to eat like our ancestors did? For example, meat is recommended for an O-type diet, but can we really compare the wild game these ancestors ate to the meat we source today in local grocery stores? The meat our ancestors consumed had a much higher percentage of omega 3s and a lower percentage of saturated fats because those animals ate different diets. Could it be that simply eating less highly-processed, additive-laden foods is at the core of these results?Īncient Vs. The Blood Type Diet is healthy in general, removing many calorie-rich inflammatory foods from every blood group’s diet. Pop Hype: Many people, including celebrities and models, have followed the diet and reported amazing energy boosts and weight loss.
The common consensus is that there has to be more room for individualizing the diet based on personal needs that extend past blood type. Or in the case of grains, a person may have allergies to gluten-containing grains, but are told their blood type can digest them with ease. For instance, blood type O is said to thrive on meat, while there are many type O’s that can also appear to thrive on a vegan or vegetarian diet. These four basic groups lump everyone into a category they might not fit neatly into.
The ABO System is the most prevalent one, used in human blood transfusion and the Blood Type Diet. While we have evolved quite a bit, D’Adamo believes our immune and digestive systems are still primitive in that they still favor the foods our ancestors ate.īlood Types Can Be Complex: T here are over 600 known blood antigens, and there are over 30 recognized blood group systems. They could also discover what forms of exercise work best and what supplements they could benefit from.ĭ’Adamo showed us that our blood types are powerful indicators of how humans evolved around the world and adapted to the varying conditions. He claimed that by eating for a specific blood type, people could prevent health issues their blood type may be predisposed to. Over time, this resulted in bodily reactions that mimicked food allergies and symptoms of a weakened immune system.ĭ’ Adamo discovered that when people ate foods in line with a blood type’s “ancestral diet” (based on where that blood type first appeared geographically), they experienced better digestion, absorbed more nutrients, and had stronger immunity and health overall. D’ Adamo found that the four blood type antigens responded to ingredients differently foods and lectins that are incompatible with a blood type agglutinate (or “clump”) blood cells, leading to inflammation in the gut. Lectins are proteins found in foods that have a negative agglutinating reaction (or “clumping” reflex) to the blood when a particular food is eaten.
The diet is based on his studies that link blood types and lectins. Peter D’Adamo, created the Blood Type Diet and popularized it in his book Eat Right 4 Your Type.
