Around 15-10,000 years ago, in the Himalayan area, the third blood group, the B group, originated. The hostile climate and inhospitable territory seriously threatened the survival of the local populations.
These men could not get food with hunting, for the shortage of game, nor exclusively with agriculture, for the aridity of the land. Herding and dairy products became an important source of livelihood and nomadic life was the consequence of the search for pastures for livestock.
The man, who originally was not structured to withstand long periods of famine and cold infections, survived thanks to a rapid but cruel natural selection that favored specimens extraordinarily resistant to extreme living conditions.
As already explained in our past episodes of this mini series, the key to the success of any evolutionary process is the ability to adapt to new food resources and the ability to defeat new diseases. Also in this case, the nomadic populations changed their organism in this direction: the new blood group presented an antigen compatible with the proteins of milk and fermented dairy products, the digestive system was structured to easily absorb foods with different characteristics between them , such as meat, cereals and dairy products, and accumulating energy supplies to be used in times of famine and, finally, the immune system was extremely efficient.
Modern man belonging to group B are particularly suited for physical activities that require great resistance, such as jogging, cycling and mountaineering and obtain excellent results in extreme sports such as triathlon.
Group B, therefore, belongs to the genetic thread of human groups that have become nomads and shepherds, whose organism was led to adapt to ever new cultures. It is endowed with unique and sometimes chameleonic characteristics with a more evolved and alert immune system and therefore able to withstand the changes and aggressions that affect the most developed societies, such as cardiovascular disorders and tumors.
We could thus summarize the type B profile:
- Has an efficient digestive system.
- Has a vigilant immune system.
- It adapts well to dietary changes.
- Prefer milk and dairy products.
- Reacts to stress by balancing mental and physical activity.
The group B diet is therefore very balanced, including the best of the animal and plant kingdom.
To avoid weight gain, group B must refrain from maize, buckwheat etc that interfere with insulin activity, hindering metabolism and causing hypoglycemia. Like group 0, it does not tolerate wheat lectin. The thyroid instead works well and the dairy products are well tolerated.
Promote weight gain
Maize, lentils, buckwheat, wheat because they reduce insulin activity. Peanuts because they reduce insulin activity and liver function.
Promote weight loss
green vegetables, meat, liver, eggs and dairy products because they activate the metabolism.
Particular foods and group B
Meat and poultry
It seems that red beef is the basis of autoimmune diseases and asthenia that affects group B. His ancestors adapted better to herding meat. Even the meat of more domestic animals is poorly indicated.
- Prefer lamb, rabbit, mutton
- Indifferent pheasant, turkey, veal
- To avoid beef, duck, pork, goose, chicken, quail, cured meats in general
Fish, shellfish and seafood
Fish is an excellent food for group B, species of cold and deep water (cod, salmon, etc.) rich as it is known for polyunsaturated oils that protect arteries and lower cholesterol levels in the blood. Crabs, lobster and seafood are not recommended because they contain lectins that are harmful to the B group. They are part of the forbidden foods, for example, in the Bible that reflects the ancient nomadic culture; the ancient prohibitions almost always reflect reasons of food hygiene.
Avoid anchovies, eel, lobster, mussels, prawns, crabs, snails, oysters, octopus, frogs, sea bass, smoked salmon, clams.
Oils and fats
Spine, sunflower, sesame and corn oil should be avoided because they contain lectins that are harmful to group B.
Chickpeas, beans with an eye and lentils should be avoided because they contain lectins that interfere with the insulin activity of group B.
Cereals and baked goods
They are well tolerated, with the exception of wheat which contains a lectin that attaches to insulin receptors present on fat cells. Bread of mixed cereals, whole wheat and soy is also to be avoided.
Indifferent rye bread, spelled bread and other cereals.
Group B can use a large quantity of vegetables except tomatoes that contain a lectin badly tolerated by the gastric wall; maize, whose lectins interfere with the efficiency of insulin and therefore alter the metabolism of carbohydrates and olives that contain microscopic fungi potentially responsible for the B group of allergic reactions. Also limit the artichokes, radishes, pumpkin.
Since group B tends to be more vulnerable to viral infections and autoimmune diseases, it is necessary to give a lot of privilege to green leafy vegetables, rich in magnesium, a mineral that helps the body to fight fatigue and therefore to safeguard the immunitary defense.
To avoid only the avocado, the persimmons, the prickly pears, the coconut.
Some species such as peanut seeds, pistachios and pine nuts should be avoided because they contain lectins that are harmful to group B.
This concludes the group B blood type episode. On our next article we will be talking of the modern era man blood group type AB, stay tuned.
