A person's blood type is one of the most important pieces of information we can have about that person, biologically speaking. It is from this data that we understand to whom they can donate blood and from whom they can receive it, for example.

There are four blood types, which also have a positive or negative Rh, so an individual's blood can be: A+, A-, AB+, AB-, B+, B-, O+ or O-.

To identify what your blood type is, you need to take a blood test, and then you can unveil the universe of the blood type diet, created by Peter d'Adamo, who says that the foods we eat affect our bodies in different ways, depending on the type of blood we have.

So a person with blood type O, positive or negative, should eat differently than someone with another blood type, in order to avoid diseases and keep the body functioning well. Below, learn more about the diet for this blood type!

Understand the influence of each type of food

The blood type diet advocated by Peter d'Adamo defines that there are three groups of foods for us: beneficial foods, which prevent and cure disease, neutral foods, which are indifferent to our bodies, and harmful foods, which can cause disease.

This is because each food interacts in a different way with our blood, depending on the blood type we have. They can facilitate or hinder digestion, stimulate or discourage the production of more saliva, strengthen or weaken immunity, and encourage the disposal of toxins or accumulate them, for example.

In this way, you can promote more efficient functioning of your body if you know the foods that are good for your blood type. Below you will find out which ingredients are best for blood type O!

Foods good for blood type O

Type O blood has a hunter profile, meaning that it needs a diet rich in protein to function fully in the body. But what are the best sources of protein for those with this blood type?

Foods that are good for blood type O are: meats (beef, venison, liver, lamb, sheep, buffalo, and beef heart), fish (cod, perch, swordfish, and sole), olive oil, flaxseed, seeds (pumpkin, sunflower, and sesame), nuts, and vegetables (seaweed, onion, chicory, dandelion, spinach, beet leaves, pumpkin, Swiss chard, artichoke, sweet potato, broccoli, endive, okra, andturnip).

In addition, the following foods are also allowed: black beans, plum, banana, blackberry, cherry, fig, raspberry, guava, and mango. Spices can be saffron, parsley, curry, cayenne pepper, and carob. All the ingredients listed need a lot of gastric juice to be digested, and this is exactly what the O-blood offers the body.

Neutral foods

Neutral foods for blood type O are those that do not cure and also do not cause illness, so they can be consumed without exaggeration, since they do not represent a proven benefit for the body. They are:

Meat from ostrich, rabbit, horse, chicken, turkey, pigeon, pheasant, and goat; fish and seafood, such as tuna, dogfish, carp, mackerel, trout, mussel, shrimp, crab, oyster, lobster, and sardines; almond, canola, sesame, walnut, and cod liver oils; nuts, which can be almonds, hazelnuts, macadamia nuts, seeds, or pine nuts.

In this case, the carbohydrates are considered neutral for the organism, and can be eaten: amaranth, rice, oatmeal, rye flour, rye or gluten-free bread, quinoa, buckwheat, and tapioca. Among the legumes, red and green beans, soybeans, peas, and chickpeas.

There is a wide variety of vegetables, such as zucchini, celery, watercress, lettuce, green olives, asparagus, eggplant, beets, carrots, sauerkraut, cilantro, mushrooms, Brussels sprouts, peas, ginger, pumpkin, yams, radish, peppers, cabbage, arugula, and tomatoes.

The following spices are also considered neutral: garlic, fennel, spring onions, saffron, rosemary, vanilla, cinnamon, cardamom, pepper, coriander, clove, stevia, tarragon, mint, bay leaf, basil, mustard, oregano, paprika, sea salt, sage, and thyme.

Finally, pineapple, persimmon, peach, raspberry, lemon, apple, papaya, watermelon, melon, strawberry, pear, pomegranate, grape, and date fruit do not harm or benefit the body of those with O blood.

Bad foods for blood type O

Once you know what foods you can eat if you have type O blood, it's time to find out which ingredients you should avoid in your diet. They can make the digestion process too easy, causing the gastric juices your body releases to build up, resulting in gastritis, for example.

Therefore, avoid: bacon, ham, quail, catfish, squid, octopus, frog; milk and dairy products, such as cream, goat's milk, margarine, yogurt, kefir, and cheeses (brie, blue, parmesan, ricotta, emmental, gouda, gruyère, provolone, cottage, cheddar, and camembert); white beans and lentils, as well as nuts, peanuts, sunflower seeds, and pistachios.

Regarding oils, one should avoid coconut, peanut, cotton, sunflower, corn, castor, soybean, and evening primrose.

Finally, it is important to avoid the following beverages: coffee, black tea, beer, soft drinks, and distilled spirits. There are also foods that should be avoided to combat fluid and fat retention, such as coconut milk, corn syrup, quail's egg, nutmeg, and aspartame.
