The peoples of the Caucasus have been cultivating this nut for more than 6 thousand years, and the Circassians bred this culture back in the 4th-3rd centuries BC.
In our country, Ivan Vladimirovich Michurin began to promote the cultivation of this crop in the northern regions. He experimentally crossed different types hazel and different varieties of hazelnuts. Thus, frost-resistant hybrid varieties of hazelnuts with good yields were obtained for middle lane Russia.
How and where is it grown
Hazelnuts are yellow-brown, almost spherical, kernels weighing from 1.5-2.5 g. In gardens, it is grown for decorative purposes (a beautiful hedge is obtained from hazel bushes), as well as for the use of its fruits in medicine, cooking and cosmetology.

Vitamins
To answer the question of whether hazelnuts are useful, you can study its vitamin and mineral composition. The following vitamins are present in the hazelnut kernel:
- choline (45.6 mg) is involved in the breakdown of fats and converting them into energy expended for breathing and physical activity;
- E (20.4) - an antioxidant in hazel, which prevents free radicals from entering cells and accumulating there, increasing the likelihood of cancer;
- PP (5,2) is part of the enzyme that provides oxygen saturation of cells;
- C (1,4) increases immunity and body resistance to viruses and infections;
- В5 (1,1) in the composition of hazelnut promotes cell regeneration and fast healing injuries;
- B6 (0.7) participates in the formation in the liver of an enzyme responsible for the processing of carbohydrates and fats into energy;
- B1 (0.3) is also involved in the processing of nutrients into energy, stimulates the brain;
- B2 (0.1) protects the nervous system from negative impact stress, therefore it is shown to men and women whose work is associated with stress ( daily rate 5 mg);
- beta-carotene (0.01), like vitamin E, has an antioxidant effect on the body.
Also, the composition contains a minimum amount of vitamin A (2 μg), B9 (68 μg), K (14, 2 μg). Fried nuts are healthier than fresh. When heated above 160 degrees, which occurs during the frying process, more than 50% of vitamin E breaks down. Therefore, the health benefits of fried hazelnuts are slightly lower.
Minerals
The beneficial properties of hazelnuts are also explained by the minerals contained in nuts, their shells and oil from them. The nuclei contain the following amount of these substances:
A small amount contains fluorine (17 μg), cobalt (12.3 μg), selenium (2.4 μg) and iodine (2 μg). The benefits and harms of hazelnuts almost do not depend on these minerals, since their content is very low. The calorie content of fresh nuts is 651 kcal. At the same time, the calorie content of 100 g of dried or roasted nuts is higher due to their loss of water.

Hazelnuts, the benefits and harms of which are considered in the material, like any other nuts, are heavy food for the stomach. It is difficult to digest in the stomach because it is rich in fiber and plant fiber (5.9 g). Therefore, it must be consumed in the morning so that the product is completely digested and absorbed until the evening.

If this dosage is exceeded, the stomach develops enzyme deficiency and food stops being digested, resulting in pain.

Some are interested in whether hazelnuts are good for children. Until the age of 14 years, the product should not be consumed. Fragile digestive and immune systems can be affected by the use of such a "heavy" product.

Their proteins are often rejected by the immune system and cause it to trigger a defense reaction - the production of allergic antibodies - histamines. Allergic reaction on hazel nuts and oil from them in men and women most often manifests itself on the skin.
For this reason, hazel nuts should not be consumed by allergy sufferers, as well as by pregnant women. The immunity of pregnant women works in an "enhanced mode", so the likelihood of allergies is higher. You can not eat them during lactation. Proteins accumulate in breast milk and can cause allergies in the child.
