Fill Up Your Plate With The Best Vitamin C Foods And Give Your Immune System Nutrition A Healthy Boost

If you want to give your immune system a helping hand, then eating foods rich in vitamin C could be the key.

Vitamin C, also known as ascorbic acid is a vitamin that our body requires every day and plays many important roles in our body.

Vitamin C Benefits

It is vital we get enough vitamin C for a number of reasons. Firstly, to help support our immune system. This is valid for adults as well as well as infants and children.

Vitamin C also contributes to the normal function of the immune system during and after intense physical exercise.

Vitamin C helps to protect cells from oxidative stress. Oxidative stress occurs when there’s an imbalance between free radicals and antioxidants in the body. Free radicals are produced in excess when we’re exposed to pollution, sunlight, cigarette smoke and other factors that occur in day-to-day life.

Added to this, vitamin C is also useful for normal collagen formation, helping to support the skin, as well as the normal function of bones, teeth, cartilage, gums and blood vessels.

Plus, we need vitamin C to help us absorb iron from food and/or supplements. If you have ever been told to drink orange juice with your iron supplement, or to eat dark leafy greens with your steak, there’s a good reason!

Vitamin C increases the absorption of non-haem iron, which is a crucial mineral needed for the formation of red blood cells, which carry oxygen around the body and provide our cells with energy.

Iron deficiency is one of the most common micronutrient deficiencies globally, with about 30% of the world population being low, so it is important that we maintain healthy iron levels.

Some foods - such as tea and coffee- can have the opposite effect of vitamin C, and actually prevent or slow down iron absorption.

How Much Vitamin C Do I Need Per Day?

According to the NHS, adults aged between 19 and 64 should get 40mg of vitamin C every day, while the NRV (Nutrient Reference Value, which used to be termed RDA) is 80mg. However many experts believe there are times when more may be beneficial.

As vitamin C is a water-soluble vitamin, meaning it comes out in our wee, we need to ensure we get adequate amounts of it every day to maintain our levels.

This is unlike the situation with fat soluble vitamins such as vitamin D, vitamin K, vitamin A and vitamin E, which are stored in the body.

The NHS advise that all children from six months up to five years are given daily vitamin supplements containing vitamins A, vitamin C and vitamin D, as well as foods rich in vitamin C.

Which Foods Are Highest For Vitamin C?
