Blood groups and diet – part 5

To achieve the greatest benefits, type A should eliminate all types of meat from the diet

On part four of this mini series we have started to review the blood type A, from the ancient times till now we have seen the change from a carnivore man into a more vegetarian type. On part 5 we will go straight into talking of the particular foods that suit better the group A blood type. So Without further adding anything let’s delve right into it.

Meat and poultry

To achieve the greatest benefits, type A should eliminate all types of meat from the diet; however it is enough to increase the consumption of fish and prefer the leanest meat such as chicken and baked or grilled turkey. Stay away from sausages because they contain nitrites, poorly tolerated by type A in possession of acid acid.
Avoid lamb duck rabbit heart liver pork beef goose salami veal
Indifferent chicken, turkey.

Fish and shellfish

Type A can take fish in small amounts three or four times a week but must avoid some fish such as sole because it contains lectins that can irritate its digestive system.

Prefer grouper, cod, croaker, salmon, sardines, mackerel, trout.
Indifferent pike, dogfish, swordfish, sea bass, tuna, salmon trout.
Eel, lobster, herring, squid, mussels, shrimp, hake, oysters, bass, octopus, sole and clams are best avoided.

Milk, dairy products and eggs

Type A tolerates small quantities of fermented cheeses, should limit the consumption of eggs but must avoid dairy products based on whole milk as its immune system produces antibodies against one of the main constituents of whole milk, D-galactosamine. This sugar, together with fucose, gives the B antigen the main enemy of its immune system. If type A suffers from bronchial asthma or chronic bronchitis, allergic reactions tend to worsen with the ingestion of dairy products.

Prefer cheese and soy milk
Indifferent yoghurt ice cream, lean mozzarella, lean ricotta, fruit and lean yogurt
Best to avoid butter, camembert, emmental, cheese, fresh cheese, ice cream with whole milk, gorgonzola, whole milk and skimmed milk, parmesan cheese.

Oils and fats

Type A does not require a large fat intake, on the contrary it must limit them. In contrast, a tablespoon of olive oil per day on the salad or on the vegetable contributes to a better function of the digestive process; it is also rich in mono-unsaturated fatty acids that help reduce LDL cholesterol and raise HDL. The lectins contained in corn oil and peanut oil, on the other hand, cause digestive problems.


Type A thrives by ingesting the proteins contained in legumes. However, the white beans of Spain, those of Lima, red beans and chickpeas contain a lectin that can reduce insulin production and promote hyperglycemia.


Type A is well suited to a cereal-based diet but should prefer less refined products. Wheat gluten, in particular, produces an excessive amount of acid that could damage their muscular system. In that case they should take fruit that generates an increase in alkalinity.

Preferably buckwheat, rice cakes, soy bread, rice rye oatmeal.
Indifferent rice and oat bran, corn flakes, corn and rice oatmeal, puffed millet, barley, puffed rice, spelled and millet bread, rye-only bread and gluten-free.
Avoid whole wheat bread, rye bread and other cereals, white flour and whole wheat flour, fresh wheat pasta, durum wheat semolina pasta.


They are vital for type A because they provide enzymes and antioxidant minerals. Better, however, to take them raw or cook them steamed or baked to reduce the loss of those substances as much as possible.
However, antioxidant-rich broccoli is recommended; reinvigorate the immune system (particularly vulnerable in group A) and prevent cellular mutations. Also recommended are green cabbage, carrots, cabbage, pumpkin and spinach; in particular the garlic that in the type A, besides the fluidification of the blood, carries out in a more punctual way its defensive and antibiotic properties. Even white onions contain a powerful antioxidant called quercetin.

Avoid the peppers and fermented olives that can cause gastric digestion disorders; also tomatoes, potatoes, red and white cabbage contain lectins which in type A and B possess an agglutinative power harmful to the digestive tract. In summary.
Prefer garlic, beets, broccoli, artichokes, carrots, kohlrabi and greens, chicory, yellow and Spanish red onions, romaine lettuce, leek, parsley, horseradish, turnips, endive, spinach, dandelion, cabbage, pumpkin.

Indifferent asparagus, avocado, beetroot, cauliflower, Brussels sprouts, chervil, cucumber, prey tops, green onions, water cress, cumin, coriander, fennel, endive, other lettuces, corn, green olives, radicchio, radishes, rocket , shallots, celery, zucchini.
To avoid Chinese white and red cabbage, cultivated mushrooms, aubergines, Greek, black and Spanish olives, white, sweet and red potatoes, red pepper, yellow, red and green peppers, tomatoes.

Fresh fruit

Type A should eat fruit at least three times a day, (unless he has calorie problems for overweight). However, it is important that you choose the most alkaline fruit such as berries and prunes to balance the action of the cereals which tend to make the muscles more acidic. Also the honeyed melons are alkaline but since they contain a high quantity of microscopic fungi (the molds) they could give digestive problems. Tropical fruits, such as mangoes and papayas, contain a digestive enzyme that is not beneficial for type A as it is for other groups. Pineapple is instead an excellent digestive.

Absolutely to be avoided are the oranges that irritate the type A stomach, poor in acid juices, and interfere with the absorption of the essential minerals. Grapefruit, on the other hand, despite being acid, exerts a beneficial action because at the end of digestion it tends to become alkaline. Even lemons, by controlling the production of gastric mucus, perform a beneficial power in type A. To increase the intake of vitamin C, a powerful antioxidant and anticancer agent, Kiwi can also be used.
The lectin contained in the banana is not well tolerated by type A. To take potassium, make use of apricots, figs and other varieties of melon.

Prefer apricots, pineapples, cherries, fresh and dried figs, lemons, blackberries, grapefruit, black, red, green and dried plums, sultanas.
Indifferent watermelon, avocado, persimmon, dates, prickly pears, strawberries, kiwi, raspberries, pomegranate, apples, winter melon, Spanish and gialletone, pears, nectarine, peaches, poses, black and red currants, grapes.
To avoid oranges, bananas, mandarins, mangoes, honeydew melons, coconuts, papayas, rhubarb.

Seeds and dried fruit

Pumpkin seeds, sunflower seeds, almonds and walnuts are valuable foods for type A because they correct the protein deficit due to the elimination of meat. However they contain a lot of calories and require a lot of work on the liver system. They are therefore to be avoided in a diet that can lose weight and in those who have hypercholesterolemia and liver failure problems.


A glass of red wine is a great help for the heart. Coffee and green tea are also fine (better if alternated) because they stimulate the production of gastric acid.
Preferred Coffee, green tea, red wine
Indifferent white wine
Avoid soda and soda water, cola-based drinks, beer, liqueurs, even black tea.

With this we have completed our journey into the diet for the blood type A. On next Monday we will start with the group B. So if you are curious to know what is the perfect nutrition for this blood type, stay tuned.

I would like to say many thanks for all the one of you who have participated to the discussions over the course of the past 4 episode of this mini series. There have been some very interesting topics popping out.

Thanks again for being with us for another great episode of this mini series and see you all on part 6.

    @Nicole Laddier every diet I come across had some sort of “Drink a maximum of two coffees a day to avoid significantly increasing the cortisol response”, so it might be true.
