Immunity and food nutrition

Immunity is an adaptive response that helps defend against attackers and repair damage. It is influenced by diet, in particular by proteins, essential fatty acids, vitamin factors and antioxidant elements. These nutrients determine the ability of the immune system to function properly. A deficiency in one or more of these elements can decrease immune functions. Similarly, certain dietary excesses can have harmful effects on immunity. Immunity and food nutrition are closely linked, let's see this together.

What Foods Boost Antibodies?

The immune system is made up of cells and antibodies. Antibodies are proteins made by white blood cells to identify and destroy infectious agents such as viruses and bacteria. Antibody production is stimulated by the presence of infectious agents, but it can also be enhanced by adequate nutrition.

Foods rich in proteins, essential fatty acids, vitamins and antioxidant elements are the most effective in strengthening antibodies. Foods that contain these essential nutrients include meats, fish, eggs, green vegetables, fruits, nuts, and whole grains. In addition, it is important to drink enough water to maintain a good level of hydration and allow immune cells to function properly. By following these recommendations, you can help your immune system fight infections better.

Studies have shown that certain nutritional supplements can also help boost the immune system. Vitamins C and D, as well as probiotics, are particularly useful for improving the immune response. If you are not getting enough of these nutrients in your diet, you may consider taking nutritional supplements to supplement them. By following these tips, you can help your immune system function optimally and better resist infections.

Also, it is important to maintain a healthy lifestyle to strengthen the immune system. Regular exercise, adequate sleep, and effective stress management are all important factors in improving immune response. By taking care of your body and your health, you can help your immune system work better and fight infections better.

How to rebalance the immune system?

There are three main families of micronutrients involved in immune functions: vitamins, trace elements and fatty acids. Vitamin A is essential for the maturation of T and B lymphocytes; it is present in carotenoids, the orange-yellow pigment of fruits and vegetables.

Vitamin D stimulates the production of T lymphocytes; it is produced from cholesterol under the action of ultraviolet B rays from the sun or it can be provided by food (fatty fish, egg yolk, butter) or even taken in the form of food supplements. Vitamins B and C are antioxidants; they neutralize the free radicals produced during the immune reaction and thus limit cell damage.

Vitamin E protects lymphocyte membranes. It is present in vegetable oils, nuts, seeds and oleaginous fruits.

Iodine stimulates the production of thyroxine (thyroid hormone) necessary for cell metabolism. It is present in iodized salt and certain foods such as seaweed, fish, beef, eggs and milk.

Zinc is necessary for the normal functioning of the immune system; it is involved in protein synthesis, cell division and wound healing. It is present in meat, fish, shellfish, pulses (beans, lentils), wheat germ and certain cereals.

Selenium is an antioxidant; it limits cell damage caused by free radicals. It is present in fish, meat, eggs, cereals and certain vegetables (mushrooms, spinach).

Polyunsaturated fatty acids from the omega-three family (alpha-linolenic acid: ALA, eicosapentaenoic acid: EPA, docosahexaenoic acid: ADH) are essential for immune regulation. They are present in fatty fish, rapeseed oil, soybean oil, flax and chia seeds.

Which dietary supplement to strengthen the immune system?

Vitamins C and D, along with probiotics, are known to boost the immune system. Vitamin C is a powerful antioxidant that helps fight harmful free radicals.

How to boost your immunity naturally?

Foods rich in vitamin C (acerola, blackcurrant, kiwi, red pepper, orange), vitamin E (wheat germ oil, extra virgin olive oil, Brazil nuts) and selenium (fish, offal, meat, whole grains) are allies of choice to strengthen your immunity. Colorful fruits and vegetables (carrot, beetroot, orange, grapefruit) are also very rich in vitamins and trace elements, essential for proper immune function. The probiotics contained in natural yogurts as well as in fermented foods (kimchi, raw sauerkraut, sourdough bread) are also very good allies to strengthen your immunity.

Finally, it is important to drink at least eight glasses of water a day to maintain a good level of hydration and promote elimination. Herbal teas, especially those based on thyme, eucalyptus or ginger, are also very effective in strengthening immunity. However, it is important not to abuse them and to seek advice from your doctor or pharmacist before consuming them.

The elderly, pregnant or breastfeeding women, children and adolescents, as well as people suffering from a chronic or immunocompromised illness must be particularly attentive to their diet and the maintenance of their immunity. If in doubt, do not hesitate to seek advice from your doctor or pharmacist.

How to increase your immune defense?

The immune system is the set of organs, tissues, cells that allow the body to protect itself from viral and bacterial attacks. Immunity is the set of mechanisms that allow an organism to defend itself against elements that are foreign to it, in particular infectious agents, and this thanks to the immune system , which implements in particular lymphocytes and antibody.

To promote the production of antibodies and thus improve the immune defences, it is important to consume foods rich in vitamins A, B, C and E. The foods to be favored are therefore fruits (especially citrus fruits), vegetables ( especially peppers, tomatoes, spinach), whole grains, soybeans, wheat germ and certain oilseeds such as almonds or walnuts.

SIHO offers a list of natural food supplements, resulting from the research and reflection of a specialist in food nutrition: Jean Christophe Gadrat .

A quick reminder: the nutrition specialist is nutritionist , naturopath or doctor.
