\n

The immune system is the body’s main defense mechanism against infections caused by viruses, bacteria and other pathogens. Its effectiveness depends on a number of factors, including diet. Adequate and balanced nutrition contributes directly to the body’s ability to respond, and is especially important during times of increased illness, such as fall and winter. <\/p>\n\n

Knowing how to choose foods to boost immunity is therefore an essential preventative strategy that requires monitoring by a nutritionist.<\/p>\n\n

[vc_row][vc_column][vc_empty_space][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=””]<\/p>\n\n

Diet to boost the immune system<\/strong><\/h2>\n\n

It should be varied, complete and rich in essential nutrients. Fruit and vegetables should be present at every meal, ensuring a supply of vitamins, minerals and antioxidants. <\/p>\n\n

[vc_row][vc_column][vc_empty_space][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=””]<\/p>\n\n

Vitamins for immunity<\/strong><\/h2>\n\n

Citrus fruits, such as oranges, lemons, kiwis and tangerines, are important sources of vitamin C, a key nutrient for the production and functioning of defense cells. Red fruits are also rich in antioxidant compounds and help protect the body from oxidative stress. <\/p>\n\n

Green leafy vegetables such as spinach, broccoli and cabbage provide vitamins A, C and folic acid, which are essential for the proper functioning of the immune system. Carrots, pumpkin and sweet potatoes are rich in beta-carotene, which the body converts into vitamin A, essential for the integrity of the mucous membranes, the first defense barrier against infections. <\/p>\n\n

<\/strong>Vitamin D is particularly important in regulating the immune response. It can be obtained through sun exposure and foods such as oily fish (salmon, sardines, mackerel), egg yolks and some dairy products. In situations of deficit, supplementation may be necessary, always under professional guidance. <\/p>\n\n

Minerals also play a crucial role. Zinc contributes to the normal function of the immune system and is found in foods such as seafood, lean meat, legumes, seeds and nuts. Selenium, found in Brazil nuts, fish and whole grains, helps protect cells against oxidative damage. <\/p>\n\n

[vc_row][vc_column][vc_empty_space][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=””]<\/p>\n\n

Foods with probiotic and prebiotic action<\/strong><\/h2>\n\n

A healthy gut is directly linked to good immunity, since a large part of the defense cells are located in the gastrointestinal tract. Natural yogurts, kefir and other fermented foods provide beneficial bacteria, while foods such as garlic, onions, leeks, bananas and oats feed these bacteria, promoting the balance of intestinal flora. <\/p>\n\n

In addition to the choice of food, it is equally important to maintain adequate hydration. Water is essential for the transportation of nutrients and for the proper functioning of all the body’s systems. Consumption of sugar, alcohol and ultra-processed foods should also be reduced, as these can weaken the immune response when consumed frequently. <\/p>\n\n

The relationship between nutrition and the immune system goes beyond food. Adequate rest, regular physical activity and stress management are complementary factors that contribute to stronger and more balanced immunity. <\/p>\n\n

Each person has specific nutritional needs, which vary according to age, state of health, lifestyle and other medical conditions. For this reason, monitoring by a health professional makes it possible to adapt the diet in an individualized way, guaranteeing an effective and sustained preventive approach throughout the year. <\/p>\n\n
