Take vitamins in spring and autumn, during stress and colds - some say. We all have a vitamin deficiency, everyone needs them every day, others say. Who is right?
The scenario of our relationship with vitamins is as unpretentious as it is typical.. We go to the pharmacy for a pill, say, for a headache, accidentally cast a glance at the shelves with vitamins, hesitate for about ten minutes and. step aside.
Or - we buy a package, accept it for a week, then we forget it and after a year we find the treasured package in the far corner of the kitchen cabinet, safely send it to the trash can.
Apparently, doctors do not convincingly explain to us the importance of these pills.. Or, on the contrary, so obtrusively that the worm of doubt crawls into the soul. Alas, there is some truth in these doubts..
One of the main arguments of supporters of the constant intake of large amounts of vitamins is the low quality of modern food.. Even if a person eats a balanced diet, he still lacks trace elements for several reasons:.
— There are fewer and fewer fresh foods in our diet, frozen, canned, concentrated and processed in other ways predominate.
- After 3 days of storing food in the refrigerator, about 30% of vitamin C is lost. And at room temperature - all 50%.
- If you put peeled potatoes in water, ascorbic acid will leave it in a few hours.
- During cooking, foods lose from 25% to 100% of vitamins.
All this is true, of course, but only in part.. Indeed, if you eat fatty foods and cakes while watching TV, it is not difficult to earn hypovitaminosis.. Yes, and there are seasonal fluctuations in the content of vitamins in vegetables and fruits.. But the increased need for them is highly doubtful..
First, do not forget about the enormous adaptive capabilities of the human body.. Reducing energy expenditure automatically reduces the need for various nutrients, including vitamins..
Secondly, many manufacturers enrich their products with vitamins - primarily juices and dairy products.. The conclusion reached by scientists as a result of hundreds of studies on thousands of volunteers around the world shocked them.. Indeed, large doses of ascorbic acid shorten the duration of a cold by about 20% and somewhat alleviate its symptoms.. But only if you're already sick.
But scientific evidence of the preventive effect of "
Long-term use of high doses of vitamin C can lead to anxiety, insomnia, and feeling hot.; and the “harmless” ascorbic acid does not work in the best way on the kidneys, blood pressure and blood.
Not to mention the fact that ascorbic acid and some B vitamins simply do not get along with each other.. And if you take ascorbic acid in high doses for a long time, you can detect a “leakage” of vitamins B12, B6, and B2.
