Blood group O is the most common blood type, and is said to have originated from Africans and American Indians. These ancestors were hunters and survived by eating meat. Therefore, this blood group should get a sufficient amount of protein from meat, and lower intake of fruits and vegetables. Avoid dairy products, wheat, pasta and most of the foods that are recommended for blood type A.

Blood group O is the most prevalent blood type in the world. Representatives of this blood group have a good digestive system and easier to decompose proteins of animal origin, so most are recommended to consume meat. Besides meat, you need to consume fruits and vegetables and to reduce consumption of carbohydrates to a minimum. The best diet for blood group 0 are those that contain a lot of protein and little carbohydrate, and that avoid the consumption of dairy products. Are you ready to accept the challenge of healthy life? Are you ready to change your diet?




Type O have high stomach-acid content, can digest meat easily. You should strictly avoid all pork and pork products including ham or bacon. Catfish, lox, herring and goose are also on the forbidden list. You can have chicken, turkey, duck, rabbit and fish like shrimp, scallops or claims occasionally, but not more than twice a week. If you are trying to build muscle mass while on the blood type diet, you can choose foods for your type that will help your body get the nutrients it needs.

Milk and Goat`s Milk



All dairy products and eggs are restricted for type O people on the Blood Type diet. Rice milk can be substituted for cow’s milk, when needed. If it’s too difficult for you to eliminate all dairy from your diet, we advise taking an enzyme supplement to help with digestion. We point out that the limitation on dairy products can end up leaving you without adequate calcium, which can increase your risk of osteoporosis.

Smoked Salmon



Type O thrive on intense physical exercise and animal protein. Unlike the other blood types, Type O muscle tissue should be slightly on the acid side. Type O can efficiently digest and metabolize meat because they tend to have high stomach-acid content. Avoid smoked Salmon because not only will be increasing the weight but will also slow down the performance of your stomach. The success of the Type O Diet depends on the use of lean, chemical-free meats, poultry, and fish. Type O don’t find dairy products and grains quite as user friendly as do most of the other blood types.

Cheese and Curd



Because cheese and cottage are not recommended for you and your stomach should immediately find a replacement for these products. Direct substitute for cheese might be soy cheese but because the taste and texture are different, it may not do the best. Also, yogurt and butter should be avoided and your breakfast may consist only eggs but while their intake should be limited to once or twice a week.




We advise you to try a small handful of pumpkin seeds or walnuts as a Beneficial snack or a hard-boiled egg or nut butters. Avoid pеanuts, not only because of their caloric value but also because they are bad for your body and slow down his work. Fats that are entering through peanuts are bad for your blood pressure and causes overweight.




Any suggestions as how to get protein and vitamins without using soy? There is no convincing evidence that soy protein has an adverse effect on thyroid function, particularly at the moderate level of consumption that would occur due to the approval of a health claim for coronary heart disease. Soy products have been consumed as a dietary staple in Asian countries for hundreds of years with no significant occurrence of goiter in that population. Goiter is primarily due to a deficiency of dietary iodine, not the consumption of moderate amounts of soy protein incorporated into a nutritionally sound diet.

Bean and Black Bean



People with type O blood will gain weight if they eat kidney beans, navy beans or lentils. Because type O individuals are supposedly descended from ancient hunter-gatherers whose diet consisted primarily of meat, poultry, seafood, vegetables, eggs, seeds and nuts, cultivated produce such as beans is allegedly bad for those with type O blood, according to diet proponents. Kidney and navy beans will interfere with their ability to burn calories, so we advise you to avoid this kind of food and live healthy as much as you can.




Why not mushrooms? Contains component which can modify known disease susceptibility. Type O person should completely avoid potatoes, avocados, all types of cabbage, eggplant, corn, mushrooms, sprouts, olives, cauliflower, oranges, berries like strawberries or blackberries and melons such as honeydew or cantaloupe. Tomatoes, peppers, asparagus, beets, lettuce, squash, apples, bananas, pineapples, grapes, peaches, pears, lemons and limes aren’t optimal for type O people, but are fine occasionally.




Eat Right for Your Type, states that type O individuals are prone to thyroid disorders and low levels of the thyroid hormone. Supposedly, they should not eat fruit like melon because these are said to inhibit production of the thyroid hormone. While an extremely high intake of fruits like melon may limit the thyroid’s ability to take in iodine so we advise to replace melon with delicious and sweet fruit.

Apple and Apple Juice



Apples range in color from lemony yellow to bright yellow-green to crimson red. Their textures range from tender to crisp, their flavors from sweet to tart and from simple to complex. Type O children should have this solid food introduced at between 7 and 9 months of age. This kind of fruit must be avoided because they contain components that are poison to your body and do not correspond to your blood type. Especially in the form of juice where the components are expressed and rapidly available for absorption. Replace this kind of fruit with any other without being orange or coconut because they are having the same effect as an apple.
