Role of immunity regarding a healthy life

Immunity is a huge network of organs, such as antibodies (proteins), white blood cells, and chemicals that protect you from invading pathogens (viruses, bacteria, parasites, and fungi) that cause diseases and infections. It is an intricate biological mechanism of your body that distinguishes the existing bodily microbe from foreign elements and rejects the latter. Hence it is essential to strengthen the immune system.

The human immune system is made up of tissues, cells, organs, and proteins. Together, they perform physical and biological processes and fight against harmful pathogens like bacteria, viruses, and alien bodies to avoid any severe infections. The immune system releases antibodies that help to kill harmful bacteria and viruses.

Do you wonder how to improve the immune system? Well, then, the answer is Immunity Boosters. Immunity Boosters help augment our immune system naturally. They work by increasing your body’s strength against dangerous pathogens. This strength is achieved by having a balanced diet, regular exercise, stress management, focusing on water intake, and improving sleep quality.

Apart from all these, one of the most important ways to acquire a healthy immune system is to increase nutrient-dense foods in your diet. With that said, let’s discuss some of the top immunity-boosting food items that can be added to your daily diet for good health.

Top immunity-boosting food items for good health

1. Citrus fruits

Citrus fruits such as oranges, lemons, grapefruits, citrus limetta (mosambi), tangerines, pomelos, etc., are packed with vitamin C, which accelerates the production of white blood cells. White blood cells are known to fight infections, remove free radicals, and inhibit cell damage in your body. This, in the long run, lessens the chances of having cancer. Since your body can not produce or store vitamin C on its own, it is essential to consume it daily.

2. Green vegetables

Green Vegetables like broccoli, spinach, and kale are ideal to meet your daily vitamin requirements. While broccoli is an excellent source of vitamins A, C, K, folate, and dietary fibre, spinach and kale are flooded with vitamins A, C, E, K, B6, riboflavin, folate, and other essential minerals and antioxidants.
