"Now it is important to include in the diet those products that contain vitamin C. First of all, these are sea buckthorn and cranberries. An important clarification: drinks made from these berries, such as fruit drinks or compotes, should be drunk without added sugar. Sugar "turns off" the immune system, and in the period after its use, it is enough just to catch some virus. In addition, you should also pay attention to rose hips. It can be brewed and drunk as tea," Stepanova said.

At the same time, the nutritionist advised to diversify the diet as much as possible in the cold season. So, among other things, you can add healthy fats to it, such as oily fish.

"Also, we should not forget about useful supplements, such as omega-3, vitamin D," the RT interlocutor said.

Do not ignore all colored products. They also play an important role in maintaining and strengthening the immune system.

"After all, they contain, among other things, antioxidants, and these are the protectors of our body, to put it simply. Everything that is now on the shelves, everything that is available, should be in the diet," the expert concluded.

Earlier, the head of the medical department of the KDL laboratory network, Olga Malinovskaya, said that the immune system in the fall is affected by a change in the daily regimen.
