Onions are a very healthy product that gives a more piquant and rich taste to soups, salads, meat and fish dishes. In addition, onions have another advantage - they bring significant benefits to the body.

Onions are probably the most common and most sought after type, at least in our area. Its healing properties have been known for a long time.

1. Onions contain 12 essential amino acids. In percentage terms, the largest amount is occupied by tryptophan - 5%. The smallest one is histidine. There is 0.01 g (1%) of it in onions.

2. Onions are rich in vitamins. It contains vitamins E and C, as well as a large number of B vitamins, including thiamine and riboflavin. Pyridoxine accounts for as much as 6%, and pantothenic acid accounts for 2%. Green onion feathers are rich in vitamin A, which people often lack.

3. Large selection of macro- and microelements in onions. Do you want to boast of an ideal memory and a sharp mind until you are very old? Then eat as many onions as possible. Not only does it keep the brain healthy, but it also helps brain cells recover after a stroke.

4. Onions improve immunity. Onions contain compounds that help the function and absorption of vitamin C, thereby helping to boost immunity.

5. Onions stabilize blood sugar levels. Onions contain chromium, which helps in stabilizing blood sugar levels. Onion essential oil acts on the human body like insulin - it evens out blood sugar levels.

6. Onions have anti-inflammatory and antiseptic effects. This fact has been proven by centuries of use of this product.

7. Fresh onions stimulate the production of good cholesterol (HDL) while keeping your heart healthy. Research by scientists from the Chinese University of Hong Kong has conclusively proven that onions, especially red varieties (what we call purple), reduce the level of “bad” cholesterol. Just half an onion a day - minus a third of unnecessary cholesterol.

8. Onions contain quercetin, a powerful substance that plays a major role in cancer prevention. It acts as an antihistamine and diuretic, fights inflammation, reduces swelling and eliminates spasms, and successfully fights free radicals.

A few years ago, somewhere from someone, as usually happens, Irunka and I learned what we need to do so that in the morning our breath is fresh and there are no tastes in our mouths...

Eat onions at night

Yes, here is such a small and short secret. Take a peeled onion and bite off a piece. Then carefully... and go to sleep... morning evening wiser.

No joke. Onions have a strong antibacterial effect and by chewing a piece with all your teeth you will eliminate all bacteria in your mouth, the benefits of onions are obvious. Toothpaste cannot do this, because it will not penetrate into all the cracks and holes between the teeth, where pieces of meat and sweet buns got into during the day while you were eating them. But the onion will get in there and destroy all the pests that have already begun to inhabit secluded corners and feast on the remains of your meal.

Sometimes small fibers of meat get stuck in the crevices of my teeth and after a couple of hours my gums begin to become inflamed. The feeling is not pleasant and it is not possible to pick out the remains of living creatures. And then a precious comrade comes to my aid - a useful onion. Chewing a small piece relieves inflammation and I no longer remember the misfortune.

Some tricks

    We all know: there are different types of onions - sweet, medium-hot and hot. The sweet one can be eaten like an apple, but you take a small bite of the hot one and everything in your mouth burns. I stew hot onions with water: I take a bite, chew it a little, wash it down with water, then continue chewing. The main thing here is not the juice, but the small pieces of onion that will get stuck between your teeth.

    As I wrote above, you can chew a piece of healthy onion for disinfection during the day, just remember that not everyone in society likes the smell of onions, although it is not as fragrant as garlic.

    Some are afraid of how their spouses will react when the onion man lies nearby. It’s hard for me to judge this, I like the smell of onions and Irunka never complained, on the contrary, she scolds me for not bringing it to her. And in the morning it is a pleasure to wake up and kiss, there is no smell of rotting.

    Although onions disinfect the oral cavity and prevent plaque from growing, they will not eat away the plaque accumulated during the day: you still need to brush your teeth at night if you do not eat onion heads.

    I've met two people in my life who have never brushed their teeth, but their teeth are like children's. The secret turned out to be simple: they did not eat sweets (they were indifferent to them) and loved to eat onions and garlic raw. I'm not a fan of onions, but I drew my conclusions.

This is such a cheap and at the same time effective way to preserve your teeth until old age; the benefits of onions are obvious. Be healthy, live long.
