The 1980s saw the development of the diet hypothesis known as the blood type diet by American naturopath Peter D'Adamo. After a few years, his book 'Eat right for your type' soon became well-known. D'Adamo asserts that the kind of meals you can eat depends on your blood type. Instead of focusing on weight loss, the blood type diet's primary goal is to adjust one's diet to avoid or even treat specific medical issues.
According to D'Adamo, the protein-carbohydrate substances known as lectins have the potential to do significant harm to human systems. The reverse is accurate when people use the knowledge to their advantage. Food contains lectins, which resemble our red blood cells in several ways. The AB-positive blood type diet states that the lectins we get from food should have a structure comparable to that of this blood group as this correlation prevents blood cell adhesions, which might cause several health issues. Therefore, there should be a conscious adjustment to this type of diet by AB-positive individuals according to tolerance emanating from the AB-positive blood type.
What Is the AB-positive blood group?
Population research shows that AB-positive individuals have the third-rarest blood type in the United States. Being able to donate plasma to any patient, irrespective of the patient's blood type, makes people refer to them as universal plasma donors. They can, therefore, donate their plasma to A-positive, B-positive, AB-positive, O-positive, and their negative counterparts. In addition to their plasma donation, platelets from AB-positive individuals are in high demand as they are relatively safe for a wide range of blood types.
The AB-positive, a universal blood recipient, can receive blood from all blood types, but can only donate to individuals with AB-positive and AB-negative blood groups. Individuals with AB-positive blood type have a sensitive digestive tract and are more open to microbial infection. Furthermore, they are more susceptible to certain types of cancer, cognitive impairment, coronary heart diseases, and diabetes. As a result, adopting a diet that provides significant benefits for combating the conditions that pertain to the AB-positive blood group is crucial.
The AB-positive blood type and diet
The type AB-positive group originates when blood types A and B co-exist. Contrary to every other gene that has "dominant" and "recessive" alleles, it is "co-dominant" for the A and B alleles in this case, with the additional presence of the Rhesus factor. The blood type AB evolved naturally rather than due to environmental factors and evolution. As a result, they benefit from and face the same difficulties associated with Type A and Type B.
The diet for the AB-positive blood type intends to improve metabolism, increase resistance to infection, and reduce the excessive production of adrenaline that occurs in reaction to stress. Dr. D'Adamo claims that Type AB has minimal stomach acid, similar to Type A, yet they also exhibit Type B's adaptability to meats. However, because of this, they do not have enough stomach acid to digest them effectively, and the meat they consume is more likely to be stored as fat. Therefore, a diet for blood type AB-positive is not strictly limited to a specific diet, but also to avoid and combine certain foods and nutrients in this diet.
Foods for AB-positive type diet
1. Animal protein
What to eat
Just like the A-positive diet, people with AB-positive blood type have a sensitive digestive system that is not suitable for the complete digestion of animal protein. However, the best animal protein diet recommended for type AB-positive individuals should contain meat from goat, turkey, mutton, rabbit, and lamb. Lamb contains nutrients that include zinc, B vitamins, and protein in abundant quantities. Furthermore, lamb is rich in conjugated linoleic acid (CLA) and stearate, both of which cause the death of cancer cells. Lamb has a higher proportion of unsaturated to saturated fats than a lot of other meat varieties. It is also a relatively lean and high-protein food, and evidence shows a mild association of high lamb with decreased rates of type 2 diabetes and cardiovascular disease (CVD). Furthermore, Mutton contains B vitamins and protein, which can reduce blood sugar levels. Consuming mutton in moderation can help people with diabetes maintain their weight because the lean protein reduces appetite while saturated fats and vitamin B promote fat burning.
What to avoid
Red and processed meat eating have been linked to a higher risk of cancer development and other health problems. According to a substantial body of research from long-term prospective cohort studies. Therefore, type AB-positive individuals should avoid chicken and processed meats such as sausage, meat snacks, and ham. According to the research, consuming processed meat daily increases the risk of dementia by 44%. Additionally, processed beef raises the likelihood of risk of Alzheimer's disease by 52%, the primary cause of dementia among individuals with this condition.
What to eat
Fish is rich in nutrients like iodine, zinc, and selenium that keep the body functioning correctly. Selenium produces enzymes that shield cell walls from cancer-causing free radicals and mitigate DNA damage by radiation. Specific toxins and iodine are necessary for the thyroid gland. Beneficial seafood products for this blood type diet AB-positive include Atlantic cod/mackerel, pickerel, salmon, grouper, walleye pike, snapper, porgy, Mahi Mahi, monkfish, red sailfish, etc. These fish contain vitamin A, which supports healthy skin and eyes, and vitamin D, which aids in the body's calcium absorption. For AB-positive individuals, it is best to consume seafood rich in DHA and EPA omega-3 fatty acids several times a week. A proper diet that frequently contains fish lowers the risk of heart disease and lessens the symptoms of rheumatoid arthritis. However, the lectins present in the sole fish are difficult for type AB-positive to digest.
What to avoid
Type AB-positive individuals should avoid blue crab, octopus, clams, anchovies, eel, brook/rainbow/sea trout, barracuda, beluga, flounder, frog, haddock, sea/striped bass, conch, Hake, halibut, salmon roe, sole (all kinds), shrimp, northern lobster, eastern/wild oysters, and whiting. Eels contain toxins that might affect the immune, reproductive, neurological, and endocrine systems. Furthermore, Hake may contain mercury, and consumption infuses it into the system. Research shows that higher mercury exposure could increase diabetes development.
3. Bread and grains
What to eat
Bread made from whole grains is an excellent provider of nutrients that support a strong immune system. They also include dietary fiber, which can help decrease cholesterol and reduce the likelihood of Type 2 diabetes, heart disease, stroke, and obesity. Grains, particularly whole grains, are vital to the diet for blood type AB-positive individuals. Whole grains such as amaranth, millet, and oat contain magnesium, folate, iron, potassium, selenium, and B vitamins, all of which work with the body to reduce the risk of coronary heart disease, diabetes, some cancers, and other health issues. Grains for diet for type AB-positive blood type should include millet, Essene bread, rice (brown, basmati, puffed, milk, flour, cake, wild, bran, white), amaranth, oat (meal, bran, flour), soy flour, rye (100% rye bread, flour), etc. Brown rice is high in flavonoids and phenols, antioxidants that assist in preventing cell aging and damage. Furthermore, brown rice is a source of minerals and vitamins, including calcium and iron, enhancing cardiac function, exercise capacity, and quality of life.
What to avoid
Diet for blood type AB-positive should exclude wheat as it lowers metabolism and promotes inefficient calorie usage. People with AB-positive blood type who have a noticeable mucus condition due to asthma or recurrent infections should also avoid wheat as it actively stimulates mucus formation. They should also limit or cut off the consumption of corn (popcorn, blue, yellow, white), cornmeal, Kamut, soba noodles, grits, refined wheat, artichoke flour, tapioca, buckwheat, sago palm, sorghum, teff. Corn contains phytic acid, which may impair mineral absorption. Furthermore, it can negatively influence blood sugar levels and put individuals with Type AB-positive blood at risk for type 2 diabetes.
It is important to note that type AB-positive individuals function best when their muscle tissues are somewhat alkaline. Thus, they must balance their consumption of acid-forming wheat with alkaline meals to maintain the acid/alkaline balance.
What to eat
Fruits contain a high percentage of fiber, vitamin C, water, and sugar. They help to lower the risk of cataracts, stroke, cancer, coronary heart disease, Alzheimer's disease, and some of the functional impairments associated with age. As part of a weight-loss regimen, fruits can help reduce calorie consumption. Diets high in potassium from fruits and vegetables can minimize the risk of kidney stones and may help mitigate the consequences of bone loss. Fruits like cherries, lemons, cranberries, pineapple, gooseberries, green/red plums, grapes, loganberries, grapefruit, kiwi, watermelon, and dried figs are highly beneficial to the diet for AB-positive blood types. Pineapples contain a natural enzyme called bromelain, which facilitates digestion by dissolving protein. Bromelain may aid in the prevention of blood clots, the inhibition of cancer cell proliferation, and the speeding up of wound healing. Grapefruit, an acidic fruit, has beneficial benefits and exhibits alkaline inclinations after digestion. Furthermore, lemons improve digestion and assist in removing mucus from the system.
What to avoid
Tropical fruits like carambolas, mangos, and guavas do not agree with type ABs. Bitter melon's high mold count makes digestion difficult for type ABs. Acidic oranges produce stomach distress in the sensitive, alkaline-type AB-positive blood type individuals' stomachs and interfere with mineral absorption.
People with AB-positive blood type are also referred to as universal plasma donors because they can donate plasma to anyone regardless of the blood type. The AB-positive blood type diet is just as unique as the blood type itself. Foods in this diet include seafood, bread, certain kinds of animal protein, and grains.
