NU.nl check daily posts on reliability. Assertion: “Red wine helps to have a cold to prevent it.”
Beautify reported in early december that red wine helps to prevent colds. Research would reveal that you are less likely to snottert and cough if you drink red wine. But is it really for this reason a good idea to in the winter more often a bottle of red wine open to draw?
Is it true?
The research, where the message of Beautify is based on, is in may 2016 published. In the study, however, not looked at the effect of drinking red wine on cold. There was, however, looked at a number of the substances in red wine, sitting, namely flavonoids. These contaminants are not only in red wine but also in fruits, vegetables, tea, and chocolate. There are different types of flavonoids, and is not in any of the aforementioned nutrients, the same kind of flavonoids.
The researchers analysed for the research multiple studies that have looked at the effect of flavonoids on infections of the throat, nose, and mouth. Also common cold is such an infection. In the analysed research were the participants in different ways additional flavonoids inside, but in none of the studies drank the participants red wine.
Fact or myth: Is every day a glass of red wine good for you?
Help flavonoids according to this survey, against a cold?
The analyzed studies of the effect of flavonoids on colds viewed were relatively small studies. The investigations jointly, 531 people share. This was half of extra flavonoids, and the other half a supplement without possible active ingredients administered.
It was observed that people who have extra flavonoids binnenkregen a slightly smaller chance to get an infection of the throat, nose, or mouth. Of the people with extra flavonoids were 127 such kind of infection, of the people without there were 164.
But, of course, not directly say that red wine helps to have a cold to prevent. The researchers write that the effect of flavonoids probably depends on the type of flavonoid and the amount of the subjects extra binnenkregen. Here is further research needed. In the analyzed studies was the dose often unclear or higher than you will normally from food can ingest.
Are flavonoids good for you?
Elise Corner, voedselveiligheidswetenschapper at the Wageningen University and Research for her doctoral research looked at the effects of flavonoids on cardiovascular disease. She writes to NU.nl that of flavonoids to various health effects are attributed. These are often positive health effects, but also sometimes negative.
Angle says that it is suggested that flavonoids have a beneficial effect could have on obesity, heart disease, cancer and the immune system. “Or flavonoids in people even really noticeable positive health effects, is still insufficiently proven.”
Angle explains that on the basis of the research that is done, no firm conclusions can be drawn about the effects of flavonoids. She tells them that there are multiple studies done on the effects of flavonoids in mice and isolated cells outside the body. But you can for different reasons not just assume that the effects found in this type of research, also for living people.
Research in people has different limitations. For example, in research with humans according to the Angle often use nutrients that are rich in flavonoids, such as chocolate, red wine or certain kinds of fruit. “If an effect is found, this can also be another ingredient of this diet, such as caffeine or alcohol. If, on the other hand research dietary supplements are used, they have often a higher dose than you are on normal nutrition within would get.”
Helps red wine against colds?
But how about now with a cold, and red wine? Corner writes that it is not likely that red wine will make you less likely to develop a cold. “You get a glass of red wine, a lot of flavonoids, but because of the alcohol you need to make sure not too much of drink. Alcohol has adverse effects on health. In addition, there is no evidence that flavonoids colds at all can prevent or cure.”
Angle also advises to not take supplements with flavonoids to swallow. “Some of the flavonoids would be possible in large quantities can have adverse effects. It is healthy to have varied and balanced food. So you get all the different important nutrients and the risk of high intake of possibly harmful substances to the smallest.”
There are a few small studies found evidence that flavonoids may be infections, such as colds, can prevent. However, there is no evidence that red wine, flavonoids it contains, helps in the prevention of colds. It seems to Corner, partly because of the alcohol in wine, it is not likely that red wine is really going to help against colds.
We rate the statement, “red wine drinking helps a cold to avoid” as implausible.
