Immunity-Boosting Foods
I wrote in my previous blog about things you can do to boost your immunity. In this blog post I focus on vitamins and minerals that are especially important for supporting your immune system. Make sure that you cover these in your daily menu.
Vitamin C (also known as ascorbic acid)
It works to improve everything from your skin health to immune function. Vitamin C protects the health of your heart, repairs and restores tissues in your body, reduces risk for gout, helps to boost the absorption of other nutrients (such as iron) in the body.

Keep in mind:
It’s best to consume foods high in vitamin C raw whenever possible. Cooking methods like boiling, simmering, sautéing, stir-frying and poaching can result in significant nutrient losses in foods containing vitamin C.
Zinc
Zinc is a trace mineral that is essential for many enzymatic reactions in your body. It's important for cell division and acts as an antioxidant. It fights free radical damage, slows down the ageing process, boosts eye health, promotes muscle repair and growth, helps with healing wounds, enhances your immune function and balances hormones. Consume 2-3 servings of zinc containing foods per day. Make sure you soak the nuts, seeds and legumes and cook well before consuming them due to phytates, as these inhibit zinc absorption.

Iron
Iron is a trace mineral present in every living cell in your body. It's a main component in hemoglobin (part of red blood cell carrying oxygen to the tissues and myoglobin (part of muscle cells holding the oxygen). Iron is important for red blood cell production to prevent anemia, energy levels, for good brain function as it carries oxygen to your brain and also for development in children. Iron is also important for properly digesting and absorbing other important nutrients from the food you eat, and it helps to bring adequate amount of oxygen to damaged areas of your body, which include cells, organs and tissues.
Iron deficiency is one of the most common nutritional deficiencies present in people. It's important to consume iron-reach foods on a regular basis. Daily recommendation for iron consumption varies based on age, where pregnant and breastfeeding women need the most.

Vitamin E
Vitamin E has strong antioxidant properties as well as it protects your cells against damage. It helps to prevent chronic diseases, reduces blood clotting, is important for healthy skin, hair growth and healthy vision. Vitamin E is abundant in the foods, so deficiency is rare, but none-the-less it's important that you focus on consuming foods rich in Vitamin E.

Selenium
Selenium is a trace mineral, which means we need to get enough of it from our daily diet. Selenium has both anti-inflammatory and antioxidant effects- it's required for the creation of glutathione, which is considered to be your body's master antioxidants. Selenium rich foods help with live function and detoxification as well as thyroid and hormonal health.
Brazil nuts- it's said it's enough to consume 2 brazil nuts a day to get the recommended daily amount. Please remember to soak them before consuming.

Vitamin D3
It's important to supplement with vitamin D3 as most of us are deficient in vitamin D. Deficiency of this vitamin can increase the risk of infection. Vitamin D help to transport calcium from your intestines as it digests into the bloodstream. When supplementing with D3, it's recommended to use it together with vitamin K2. Vitamin K helps to take then the calcium from the bloodstream and deposit into bones and teeth. So these two vitamins work hand-in-hand.
Vitamin A
Vitamin A is a soluble vitamin important for healthy vision and skin. It's also important for the development of specific immune cells to fight infections and inflammation.

It also helps to form hemoglobin and neurotransmitters and regulation of blood glycose. Vitamin B6 helps to improve the immune function by fighting off the foreign invaders in your body.
