When evaluating the beneficial properties of the product, you need to pay attention to what vitamins are contained in onions and how they affect the state of the body.

Thiamine (B1)

100 g of fresh vegetable contains 0.05 mg. thiamine. It is necessary for nutrition of skeletal muscles, regulation of growth processes. The human body cannot synthesize it on its own, so the only way to get vitamin B1 is to eat foods rich in it.

Riboflavin (B2)

Onions contain a small amount of this organic compound - only 0.02 mg per 100 g of fresh product. Riboflavin significantly accelerates the processes of regeneration and metabolism in the body, but since its share is small in onions and green onions, it will not be possible to correct an acute vitamin deficiency using this product alone.

Nicotinic acid (B3) and folic acid (B9)

For people who are prone to thrombosis, it is important to know which vitamins in onions have an anticoagulant effect. These are nicotinic acid (0.5 mg per 100 g) and (9 μg per 100 g). Both organic compounds have a positive effect on the processes of cell division, the walls of blood vessels.

Pantothenic acid (B5)

The substance can accelerate water-salt metabolism and ensure the absorption of other B vitamins in the body. 100 g of onion contains 0.5 mg. pantothenic acid - this is enough for daily consumption of the product in such an amount to fill the daily human need for vitamin B5.

Ascorbic acid (C)

100 g of the plant contains 10 mg of the substance - this is about 3 times higher than the proportion of all B vitamins combined, which are present in this vegetable. This ratio clearly indicates which vitamin contains the most onions. Ascorbic acid is involved in the processes of blood clotting and helps the body develop resistance to infectious diseases.

Minerals in the product

In addition to vitamins, onions contain macro- and microelements that support the functioning of internal organs, the circulatory system and affect the appearance of a person.

Potassium

100 g of the plant contains 175 mg of the macronutrient. This is 3 times more than the amount of each of the other six minerals that are present in this product. Potassium is responsible for the normal functioning of the posterior and forebrain and the maintenance of acid-base balance. But the daily requirement of an adult organism for this macronutrient ranges from 1800 to 4500 mg, so onions cannot adequately replenish it.

Calcium

The substance strengthens bones and teeth, participates in the processes of blood coagulation, secretion of hormones and normalization of the endocrine system. The content in 100 g of onion is 31 mg. Its absorption depends on what vitamins the onion contains. The main condition for good absorption is the presence of D vitamins, but they are not part of this product, so the calcium obtained by eating onions is not able to sufficiently strengthen the skeletal system.

Sulfur

There are 62 mg in 100 g of fresh product. sulfur. Since the substance contains melanin and keratin in its composition, onions can positively affect the condition of the hair: onion gruel masks make them smooth and shiny.

Phosphorus

Chlorine

The substance takes part in creating a favorable environment for the production of gastric juice enzymes, it is found in muscle and bone tissue. In addition, chlorine is involved in the production of hydrochloric acid, so when eating onions, the processes of food digestion improve.

Magnesium

100 g of fresh product contains 14 mg. magnesium, but the degree of its absorption by the body depends on which B vitamins are in the onion. Since the vegetable contains riboflavin, it slows down the absorption of this macronutrient. improves blood circulation, regulates the processes of protein synthesis and helps normalize intestinal motility.

Sodium

The plant contains a very small amount of this mineral: only 14 mg. per 100 g of the product. It is practically not absorbed by the body due to the fact that the vegetable contains a large amount of potassium, which inhibits the absorption of sodium by the small intestine and stomach walls.

What can interfere with the absorption of useful elements?

• Thiamine and riboflavin will not be absorbed if onion is consumed while intoxicated or if the tincture of this vegetable is prepared with alcohol. Both of these substances are insoluble in alcohol. Alcohol will slow down the absorption of potassium.
• All and a significant part of ascorbic acid will evaporate during the heat treatment of green and onions.
• If you eat a vegetable along with fatty foods, then the minerals that make up its composition will be poorly absorbed by the intestinal walls. This is especially true for magnesium.

Information about which vitamins and minerals are present in onions more than in other vegetables will help when using the product as a therapeutic and cosmetic product.
