100 g of the plant contains 175 mg of 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 anterior regions of the brain and maintaining the acid-base balance. But the daily requirement of an adult body for this macronutrient is from 1800 to 4500 mg, so onions cannot sufficiently replenish it.


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

In 100 g of fresh product, 14 mg is present. 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. Magnesium improves blood circulation, regulates protein synthesis and helps to normalize intestinal motility.


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

Which cooking method is the most caloric vegetable

The most nutritious is dehydrated (dried) onions in the form of flakes. It is usually made on an industrial scale using special drying machines. The energy value in this case is so high due to the complete removal of water from the vegetable, which makes up 90% of its raw mass. By the way, you can also read our article on the calorie content and BJU of green onions.

Next in calories are dried vegetables cut into rings or half rings, deep-fried and sautéed. Baked, boiled, and raw are the lowest calorie options.

Calorie content of red and white onions: is there a difference

Yes, there is a difference. It cannot be said that it is essential. How many calories a particular variety contains depends on the difference in the content of proteins, carbohydrates and other substances. Regular onions contain 42-44 kcal per 100 g, while sweet varieties contain 32-35 kcal. At the same time, the white variety, and purple, and red can be sweet.

The chemical composition of red onion differs little from white onion in vitamins. The only difference is in the composition of the husk, which is used in folk medicine - in white there is practically no vitamin C.


The vegetable contains a lot of potassium, phosphorus, sulfur. The detailed macronutrient composition can be found in the table.

Of the macronutrients, blue, red bulbs contain more sulfur than white bulbs. This makes it more useful for cleansing the blood, removing cholesterol, and hematopoiesis processes.

Trace elements

Let's see what trace elements are in the lead in terms of content in the product.

These are averages and may vary slightly depending on how sweet the variety is.

What other substances does onion contain?

Onions are rich in vitamins and minerals. But besides them and nutrients, the vegetable contains valuable biologically active compounds:

  • Phytoncides are volatile substances that have a detrimental effect on bacteria, protozoa and viruses.
  • The flavonoid quercetin is not an essential nutrient, but it has a pronounced anti-inflammatory and antioxidant effect.
  • Allicin - is one of the main active substances of garlic, but it is also contained in onions and has a strong antibacterial activity, which it retains both in the gastric juice and in the blood.
  • Anthocyanins - compounds from the group of glycosides, are present in purple and red bulbs and their husks, causing their color to reduce inflammation, oxidation processes in cells (that is, they are antioxidants).
  • Organic acids - malic, citric and others.

In order to choose the right onion, it is enough to follow simple advice when buying.

  1. The bulb must be firm, since softness in this case is a sign of decay that has begun.
  2. The color of the husk should be uniform: golden, white or reddish, depending on the variety.
  3. The bulb should not have black spots or spots, signs of fungal diseases.
  4. Also, there should be no green shoots - they usually appear on already old bulbs.

Store the plant in a dry place away from direct sunlight. Wooden boxes are ideal for this, which provide the necessary ventilation.

If you used one part of the onion, then it is better to wrap the remaining half with cling film and put it in the refrigerator: this way it will not only last longer, but also will not spread the characteristic onion aroma throughout the refrigerator.
