Blue onion: health benefits and harms

In nature, a bow that has a true blue color does not occur. Blue includes varieties that have a color from light purple to almost black with purple and bluish hues. The taste is slightly sweet. But varieties grown on moist soil with a lack of sunlight are sharper than yellow onions. Sweet varieties: "Yalta", "Albina". The latter is extremely rare due to low productivity.

What is the difference between blue bow and usual

The main differences are caused by the difference in chemical composition:

The benefits and harms of blue onions

  1. Blue varieties have less potassium, there is no rubidium, which slightly slows the rhythm of the heartbeat, while onion, in large quantities, can lead to bradycardia.
  2. Blue varieties contain fluorine, which strengthens tooth enamel, but is contraindicated in case of excess of this chemical element in drinking water.
  3. In blue grades, the effect of sulfur is softer, therefore less irritating to the gastrointestinal tract.
  4. Purple onion has more lutein - minimizing the irritant effect on the gastrointestinal mucosa slightly thickens the blood compared with onions.
  5. Purple varieties have more iron, which helps transport oxygen through the blood.
  6. Dark grades have less vitamin B4, so the diuretic effect is weaker than light ones.

Other differences:

  1. When cooking, it acquires an unpleasant bluish tint.
  2. Taste gamut is richer than usual, so it is possible to use in spicy mild sauces, ideal for seafood, sandwiches.
  3. Blue onion is more demanding on storage conditions, with a lack of heat it will be small, burning with bitterness.
  4. Unlike usual, the characteristic bad breath lasts no more than 20 minutes.

What is more useful

The degree of usefulness depends on the purpose of the application:

  1. Viral diseases - healthier onions. An exception is purulent tonsillitis with a significant lesion of the mucosa. In this case, apply only light purple, sweet - 1 to 1 with butter and honey.
  2. Liver diseases of an infectious nature, steatosis - any sort of blue on 1 part onion and 3 parts honey. Take sweet varieties. Bitter ones accelerate the elimination of fluid from hepatocytes.
  3. Prevention of viral diseases, disorders of the gastrointestinal tract (putrefactive processes, decreased acidity of digestive secrets) - blue onions are preferable. It strengthens the immune system in a natural way, and does not replace its effect. The action of a bulb like an antibiotic is a local effect plus the acceleration of the removal of dead phagocytes from the body.
  4. Arrhythmia, jumps in blood pressure, disorders of the central nervous system - only blue. It has a lower concentration of metals from the first column of the periodic table, there is no hard ionizing effect, as when using onion.
  5. Helminthiasis, skin infections - onions. It is also more effective at high temperature or if it periodically rises for 3 days or longer, since the probability of fermentation in the digestive tract is lower. Stomatitis, gingivitis, herpes - 1 to 1 with honey plus 1/3 of the total alcohol.
  6. Weakness, dizziness and other symptoms of diseases associated with impaired cardiovascular system and iron deficiency - blue onion. To increase efficiency, use with lean meat, pork or veal liver, fish.

Composition and calorie content

The calorie content of blue onion depends on the content of saccharides in the bulb. The average calorie content is 40 kcal / 100 g. In sweet and non-hot grades, calorie content can exceed the average value by 20-30%.In sweet burning phytoncides, they break down carbohydrates during assimilation, reducing calories by 30–40%.

The following chemical elements and biologically active substances are included in blue onion varieties.

Vitamins:

  1. B4: acceleration of fluid separation in the small intestine, a slight decrease in acidity in the digestive tract (properties are manifested when eating a vegetable in its raw form).
  2. B9: increased likelihood of conception, slowed down the synthesis of histamine, prostaglandins - the removal of inflammation (found in large quantities, the concentration increases during frying, drying).
  3. C: strengthening immunity, increasing the efficiency of assimilation of iron, accelerating fluid metabolism.
  4. E: strong antioxidant, slowing down the aging process of cells (high concentration).
  5. H: acceleration of protein metabolism, a set of muscle mass, an increase in the density of muscle fibers of myofibrils (low concentration).
  6. K: increased blood coagulation, stimulation of hematopoietic function of bone marrow (low concentration).
  7. PP: acceleration of the passage of nerve impulses in the cerebral cortex, along with phosphorus and magnesium, strengthening of the walls of blood vessels (contained in small quantities).

Minerals:

  1. Potassium: slowing of the rhythm of the heartbeat, acceleration of metabolic processes, uniform distribution of substances throughout the blood (high concentration).
  2. Calcium: acceleration of the rhythm of the heartbeat and oxidative processes, strengthening of bone tissue (contained in small quantities).
  3. Iron: It is part of the molecules that transport oxygen through the blood (transferrin, hemoglobin), destroys bone tissue in large quantities (low concentration).
  4. Magnesium: strengthening the walls of blood vessels, accelerating fluid metabolism, normalizing redox processes (contained in small quantities).
  5. Sulfur: stimulation of the absorption of amino acids, softening or stabilization of allergic processes (in small quantities).
  6. Fluorine: strengthening tooth enamel, neutralizing the ionizing effect of potassium, rubidium (low concentration).
  7. Chromium: a decrease in local temperature in areas of inflammation, a slight stabilization of blood sugar, forms toxic dichromates with potassium and rubidium (low concentration).
  8. Zinc: in small amounts, normalization of phospholipid metabolism, improvement of blood circulation in the capillaries (low concentration).

Blue onions are rich in lutein, which provides a bactericidal and tonic effect.

What is blue bow useful for

General benefit

Blue onion has the following beneficial properties:

What is blue bow useful for

Contrary to all assurances, in a dry place at a temperature of 18–25 ° C it will be stored until spring. Medium-sized sweet onions are best stored either in a wreath or in a cardboard box near the convector. If it begins to dry out, put 200 ml of water on the convector overnight, changing every day. Stack only perfectly dried onions, otherwise the middle and lower layers will sprout.

Is it possible to fry blue onions

In fried form, it comes out tastier than onion and somehow resembles mushrooms. You need to fry the onions over low heat in a small amount of fat. Dry the pan. Pour in sunflower or olive oil, wait until it boils. Spread finely chopped onions. Animal fats are not suitable for blue onions. Deliciously goes in butter.

If the shelf life of the bulbs is coming to an end, they can be re-dried in a large amount of butter or spread. Cool, pour into a container and freeze.

Interesting facts about onions

  1. The maximum of nutrients is in the upper layer. Even if it’s harsh, don’t throw it away! Rigidity is removed by blanching.
  2. Sweetness and hotness depend not so much on the variety as on the soil on which it was grown, the amount of precipitation during the season, and the average daily amplitude of temperature fluctuations.
  3. Dark varieties are the result of crosses between Spanish and Portuguese onions. To maximize the manifestation of all the taste and healing properties, it must be grown on stony soil with a fertile layer of not more than 30 cm. At night, the stones give off heat, which ensures round-the-clock uniform vegetation.
  4. It is necessary to fertilize the soil with bird droppings, straw, cattle droppings, taking all the components in equal parts. This fertilizer slowly rots out, which eliminates rotting of the bulbs and holds heat well in the soil.
  5. Bitter varieties should not be taken for conservation. After soaking, the aroma of onions intensifies, a bouquet of specific flavors disappears. If this happened, for the marinade take 0.5 liters of cherry and plum juice, a glass of sugar, 150 ml of vinegar, 1 tbsp. salt. The marinade is enough for 3-4 liter cans, depending on how the onion picks it up. Bring the marinade to a boil over low heat, stirring occasionally. Do not stack too full cans. Onion can strongly absorb marinade, increase in volume. Sterilize for 10-12 minutes, consume after a month. Shelf life is one year.
