Immunity

The immune system is a large network of cells, organs and proteins that protects our body from harmful microorganisms and toxins. When the immune system is functioning optimally, it does an excellent job of protecting the body. However, a weakened immune system can increase the risk of infectious diseases such as colds and other infections. Various vitamins and minerals ("micronutrients" "macronutrients") are essential for a healthy immune system. You can find more information in the article - essential nutrients for the immune system. The main substances that play an important role in the immune system are:

• vitamin A
• vitamin C
• vitamin D
• vitamin E
• vitamin B6
• vitamin B12
• zinc
• iron
• copper

Ideally, we would all get optimal amounts of these elements if we had a good and balanced diet. Otherwise, there is a risk that the necessary nutrients may be lacking. Many people around the world are malnourished. For example: In the United States, nearly 95% of the population do not get the daily requirement of vitamin D, 84% do not get enough vitamin E, 46% do not get enough vitamin C, 45% do not get enough vitamin A, and 15% do not get enough zinc. Research shows that even a small deficiency in one or more of these vitamins and minerals can impair immune function. Many factors, such as stress and infection, can further deplete nutrient stores throughout the body. Meanwhile, aging increases the body's need for micronutrients. People over 50 generally need more of certain nutrients, including vitamin D, calcium, vitamin B6 and vitamin B12.

Food supplements and immunity

To maintain a good immune system and meet nutritional requirements, multivitamins can be taken, or superfood which contain 100% Recommended Daily Allowances (RMVs) for each nutrient. If you are already deficient in nutrients, you probably need to supplement with more than what is in the multivitamin.  

Can probiotics help the immune system?

Many consider probiotics, or "good bacteria," to be another natural way to boost immunity. They are known to play an important role in maintaining a healthy balance of bacteria in the gut, and new research supports the idea that they have a positive effect on immunity.

How to boost your immune system naturally

A healthy lifestyle can help the body's natural protection and well-being:

• Do not smoke
• Avoid excessive alcohol consumption
• Wash your hands often
• Manage stress
