Useful and healing properties of the fruit and leaves of the hazel tree

The benefits of hazel are invaluable! The composition of large hazelnuts - the perfect combination of healthy fats, dietary fiber and protein. Dietary fiber slows the release of glucose, which contributes to the body's energy for a long time. This increases the endurance of the body and reduces recovery time after exercise. Therefore, the nuts will be useful to athletes, active children, people with increased physical activity at work.

Hazelnut nuts contain a record amount of potassium and magnesium. These macronutrients are participants in the regulation of acid-base balance, the heartbeat cycle, increasing the tolerance of oxygen deficiency by the myocardium (heart muscle).

Potassium in the body replaces sodium, the excess of which leads to the formation of excessive fluid and is a big burden on the heart. Potassium strengthens the walls of blood vessels, inhibiting the development of their permeability.

Nuts will be useful for:

  • heart failure;
  • coronary heart disease;
  • senile wear of the myocardium;
  • atherosclerosis;
  • varicose veins;
  • angina pectoris;
  • sclerosis of cerebral vessels;
  • thrombophlebitis;
  • hemorrhoids;
  • hypertension.

Phosphorus and calcium form a solid bone structure and are participants in remodeling (renewal) of the skeleton and teeth. Another function of phosphorus is the transfer, transformed from incoming food energy to the tissues of the muscles, brain and nerves. It accumulates in the phosphorus molecules and enters the blood, through which it is carried to all parts of the body. Therefore, muscle contraction and mental activity without phosphorus is impossible. Magnesium reduces nervous irritability and regulates respiratory functions.

Therefore, nuts are recommended to use when:

  • increased mental activity;
  • neuropathies;
  • joint diseases;
  • bronchopulmonary diseases;
  • rheumatism;
  • senile dementia.

Stable intake of iron in the body prevents the risk of anemia and supports the endocrine system.

Fatty acids in combination with minerals have a beneficial effect on the digestive system, help to heal ulcers and gastritis. They increase bile secretion and reduce blood toxicity. Therefore, nuts are included in the clinical nutrition of patients with hepatitis B.

Zinc is an essential element for men's health. He is involved in the production of male hormone - testosterone, which regulates the sexual functions and the quality of sperm.

Vitamin E regulates tissue renewal, which accelerates the healing of wounds, ulcerative lesions and skin irritations. For the ability to restore the natural collagen of the skin it is called beauty vitamin. Vitamin E is an antioxidant that promotes the removal of toxins from the body. Together with beta-carotene, it improves lung and respiratory function.

Vitamin PP is an indispensable participant in the formation of the immune system, metabolism, cellular respiration and oxidation-reduction reactions of the body. B vitamins regulate cell metabolism, promote the absorption of fatty acids and macronutrients.

The hazel fruit contains the plant component paclitaxel. This substance has carcinogenic properties, so it is used in the compositions of drugs for the treatment of malignant tumors. Daily nut consumption is good prevention of cancer and possible relapses after a course of antitumor therapy.

Therefore, to prevent complications and the full formation of the fetus requires a constant flow of nutrients from food.

The products recommended for pregnancy include hazel nuts. First of all, they provide a stable supply of the most important macronutrients: potassium, calcium and phosphorus. This strengthens the blood vessels, the failure of which causes complications during pregnancy - preeclampsia, varicose veins, edema.

Calcium and phosphorus are involved in the formation of the bone system of the fetus, thereby preventing the development of rickets. Mother's bone tissue is also strengthened, the load on which increases with each passing month.

Vitamin E is necessary for the formation of the respiratory system of the fetus. In addition, the substance contributes to the maturation of the placenta, regulates its functions and cellular metabolism, prevents detachment. Tocopherol is involved in the synthesis of the hormone prolactin, which provides lactation. Vitamin A is a participant in the formation of fetal visual pigments.

During pregnancy, the body increases the volume of circulating blood to feed the growing uterus. Accordingly, the need for iron, the main participant in blood formation, increases. Against this background, iron deficiency anemia often develops. Consuming nuts prevents this problem.

More caution is necessary to approach the use of nuts during lactation. It is an obligate allergen that can cause an inflammatory reaction in the child’s body.
