Vitamins and trace elements necessary for metabolism and immunity are primarily found in foods. These are not only fruits and vegetables, but also meat, fish and dairy products. However, the greatest amount of vitamins is found in fresh fruits and vegetables. That’s why signs of vitamin deficiency occur most often in the winter and spring, when there is a lack of plant foods. Of course, you do not have to become a vegetarian right away, but it is necessary to eat more vegetables, fruits and herbs. It is recommended to preserve and freeze plant foods, so that you can eat them later and get the necessary vitamins, macro-and micronutrients. Although we should remember that natural products contain more useful substances than those that have been heat-treated.
