With low temperatures in winter, you rarely have cold and seasonal flu under low temperatures.
There are a variety of methods and recipes for fighting colds at home and the number of viruses that cause about 200 viruses.
These therapeutic methods share the very essence of the idea of strengthening the immune system. It is important to note that any virus that enters the human body faces two defenses.
The first is known as "innate immunity" and attempts to expel invasive cells. The second is a system capable of adapting to different variables. It creates memory cells containing details of new diseases so that the body can fight them if they attack them again.
That's why we have an illness like "chicken pox" once in our lives. However, it has been hit by colds dozens of times because the viruses that cause them – which change in appearance as they are transmitted from one person to another – confuse these cells. memory.
Charles Banguam, head of the infectious diseases department at London College Imperial College, may be surprised to see that eating what is called anti-cold foods helps to get by. Bangham says his presence at the dining table will make no difference, according to a report "BBC Future".
Complementary supplements (or dietary supplements) with essential nutrients, such as vitamins, zinc and iron, will not be of any help, unless you miss a particular substance, he said. .
"If you have a balanced diet system, adding more of these substances will not strengthen your immune system."
Food supplement solutions
However, studies of treatment methods and cold prescriptions have shown that the consumption of foods or dietary supplements such as these can make the difference.

In fact, the vast majority of these studies focused on dietary supplements and not on foods. In fact, no reliable scientific research has been conducted to determine whether a common method of treating colds, such as eating chicken soup, is really beneficial or not.
Garlic
Among the supplements that can actually help, garlic is considered a very popular therapeutic remedy. In a small-scale study, 146 healthy adults received a placebo or daily supplement of garlic for 12 weeks in the winter.
Although the placebo group suffered from 65 cold hemorrhages resulting in sick leave, for a total of 366 days, the number of cases among members of the other group did not exceed 24 and 111 days sick leave.
Vitamin C is another dietary supplement used by many when they experience cold symptoms. Some studies have shown that taking this type of vitamin can be beneficial, but not as much.
A study of 29 scientific studies on the benefits of vitamin C as a dietary supplement showed that it did not significantly reduce the risk of colds or even significantly the symptoms. But the study showed that eating reduced the incidence of children by 14% and adults by 8%.
The researchers concluded that it was worthwhile to experiment with this dietary supplement to check whether it is useful or not for the treatment of colds, given the fact that the treatment does not result in any treatment. low risk.
Orange
Orange juice may be less useful because there is no strong evidence that it helps to prevent colds, reduce symptoms, or reduce the duration of suffering.
"It's because the orange juice does not contain enough of this vitamin," says Harry Himele, a public health researcher at the University of Helsinki who is studying the effects of the Vitamin C. "This can have the same effect as eating supplements that it contains every day.
Although the normal size of a small bottle of orange juice contains, according to the US Department of Agriculture, about 72 milligrams of vitamin C, more than the recommended daily dose of only 40 milligrams, less than can be obtained using many supplements.
Zinc
We now come to the zinc material. A study conducted to examine the effectiveness of ingestion of zinc-containing emulsifiers daily indicated that this would reduce by about one-third the duration of nasal discharge or spotting. Nasal obstruction. It also reduced the number of sneezing times by 22% and coughing by almost half.

The study concluded that the consumption of emulsifying tablets containing 80 milligrams of this substance during the first 24 hours following the onset of cold symptoms – and continues daily – can lead to the treatment of this condition.
However, Himmila believes that to obtain accurate results for these studies, one must focus on the problem of complete cold healing, not on its duration.
In a study of 199 patients with colds, people who consumed emulsifiers containing zinc recovered three times faster.
Most often, scientists prefer vitamins and minerals contained in foods to dietary supplements. But for vitamin C, it is often easier to get high doses of vitamin C supplements.
In order to get the most out of zinc to deal with colds, it must be taken, he says, in the form of emulsifying tablets and not in the form of zinc tablets or foods rich in this substance.
"Emulsifying tablets containing zinc dissolve slowly in the throat and are confined to this area," says the researcher. "We do not know what is the biochemical mechanism of this effect, but studies have shown the effectiveness of these tablets (for the treatment of colds) Great, it took up to 30 minutes to dissolve in the mouth. "
Relieve cold problems
Of the problems encountered in this case, researchers do not tend to verify that members of the research sample suffer mainly from a lack of substances such as vitamin C or zinc before the beginning of the treatment system. As a result, the benefits of some of the participants in the studies may be due to the fact that they have overcome the shortage they were causing.
Another problem is what we might call "the power of illusion". While many scientific studies – such as those previously mentioned about the benefits of garlic-based food supplements – have tried to avoid this through a control group with a pseudo-pill placebo and another group that actually supplements, In real life.
Those who swear that food and drinks, such as chicken soup and orange juice, have already recovered from the cold, although the scientific evidence to prove it, if any, is limited.
The power of illusion or illusion
This is what makes us say that what has been said in this regard is the result of an "illusory power" or illusion that has proved effective in alleviating many symptoms, although the reasons for this phenomenon have not yet been fully understood.

The effect of such an illusion – be it vitamin C or chicken soup – may be enough to help us recover from the cold.
A study of people who believe in the health of what has been said about the ability of a herbaceous plant – grown in North America and used as a treatment – to fight colds and others that do not not believe, the first group experienced lighter and shorter cold symptoms when taking daily doses of Plant Therapeutic substance, compared to the second category.
Previous studies in which participants did not know that they were following a treatment derived from the plant, no improvement was associated with cold symptoms.
This can have an effect in the opposite direction. It has long been thought that drinking milk leads to the release of larger amounts of mucus in people with colds, although this has been scientifically proven. However, one study found that those who thought that milk had this negative effect had suffered from respiratory symptoms after feeling a measure of it.
Felicity Bishop, an associate professor of health psychology at the University of Southampton, UK, points out the similarities between the placebo pill administered by researchers and the illusions of real life.
"The effect of the placebo pill comes from the trusting relationship between patients and healthcare professionals, similar to what parents do when we are young," she said. "What matters here is the nature of the relationship, not the identity of the parties."
She adds that the inspiring power of a particular food does not come only from trusted friends or family members, but can be reinforced by the way food is marketed.
Bishop points out that when a doctor follows a transparent approach and tells patients that a drug is only a placebo, this has led to some patients' help and to a improvement of the disease.
On the other hand, there is another benefit for foods that are thought to have a positive effect in the face of colds, namely that it is a common feeling of comfort for some. Sara Schenker, a nutrition expert, says eating chicken soup, for example, can help a little colder feel better.

There are other factors that determine our ability to avoid colds, other than simply eating as much vitamin C as possible. It depends to a large extent on the person and his nature, and the extent to which he believes in the effectiveness of ghost drugs and home remedies, as well as his genetic makeup.
"The genetic makeup of some people makes them particularly vulnerable to certain diseases," Bishop said.
She adds that genes play a role, even partially, in some people with simple diseases such as the flu.
