Vegetarian diets are becoming increasingly popular today, and more and more people are abandoning the consumption of foods of animal origin.

Although many people consider a vegetarian diet low in animal fats to be healthier, this diet carries a number of risks.

Studies conducted by experts from the University of Oxford show that the exclusion of animal products from the menu significantly reduces the body's defenses.


Strict vegetarians, who do not even consume milk and eggs, are deficient in important vitamins, essential amino acids and elements that cannot be obtained from plant foods.

Lack of protein in the diet lowers the body's resistance and makes it susceptible to infections and viral diseases.

Vegetarians are also deficient in vitamin B12, the source of which is animal products. According to experts, vitamin B12 deficiency is at the root of cardiovascular problems. The vitamin increases the level of homocysteine ​​- a type of amino acid. Its excessive increase in the blood increases clotting and predisposes to thrombosis and restriction of blood flow in the vessels, leading to heart attack and stroke.


B12 deficiency also leads to a number of changes in the morphology of blood cells and even damage to the central nervous system.


The main source of B vitamins is beef and especially beef liver, where they are in the most easily digestible form.

A large-scale study that looked at the health of a large group of vegetarians over a five-year period found a decrease in cognitive and brain function in almost all volunteers. There was a delay in brain activity, impaired memory and concentration and reduced cognitive abilities. A CT scan also showed a decrease in brain volume and mass.

In older volunteers who adhered to a vegetarian diet for many years, adverse changes in the central nervous system were more pronounced.

Nutritionists are adamant that in order to be healthy, the diet must be balanced and varied. According to doctors, the complete avoidance of foods of animal origin does not improve health and does not prolong life. For those who are determined to give up meat, it is still recommended to consume fish, seafood, eggs, milk and dairy products.
