You may have heard that vitamin A provides the health of your eyes and skin. Are you wondering about your vitamin A intake and the need to take a supplement? Read on what you need to know about vitamin A.

What are the benefits of vitamin A?

Vitamin A is a fat-soluble vitamin that is stored in our liver. It contributes to the natural development and normal growth of the body while maintaining the health of our eyes, skin and immune system. This makes a very important contribution to a healthy vision.

It is usually found in foods of animal origin, but it can also be made from compounds found in foods of plant origin, called carotenoids.

What are carotenoids?

Carotenoids (phytonutrients) found in various amounts in fruits and vegetables. Brightly colored foods such as dark green, orange, yellow and red fruits, and vegetables contain carotenoids.

There are several types of carotenoids that act differently on our bodies. For example, some carotenoids (such as beta-carotene) can be converted by our body into vitamin A.

Health Zigzag recommends eating a dark green fruit or vegetable and an orange fruit or vegetable every day. Why? Because the carotenoids in these foods contribute to our daily intake of vitamin A.

* In retinol equivalents (ER).

What are retinol equivalents? Vitamin A and carotenoids measured differently. It takes a lot more carotenoids to get the same amount of vitamin A from animal sources. Retinol equivalents used to quantify these differences. Here is the formula:

1 μg vitamin A = 12 μg carotenoids = 1 ER

 



Do I need to take a vitamin A supplement?

No. Taking vitamin A supplements not recommended. High doses of vitamin A are toxic. Our liver can acquire vitamin A for very long periods. This means that even if we do not eat vitamin A-rich foods for a few days, we are not at risk of deficiency.

A balanced and healthy diet, which meets the recommendations of Canada’s Food Guide, will provide you with a sufficient daily intake of vitamin A from foods of animal origin or fruits and vegetables rich in carotenoids such as dark green fruits and vegetables.

Can the skin turn yellow if we eat too many carrots? Yes. This phenomenon occurs because the cells that are under the skin store beta-carotene (which is a yellow-orange pigment). Consuming a large amount of beta-carotene from foods can make the skin yellow, however, there is no danger to health.

 



Vitamin A and pregnancy

Pregnant women should not take vitamin A supplements and should limit their liver consumption because of their high vitamin A content. Excess vitamin A can cause birth defects.

Supplements designed for pregnant women contain an adequate and safe amount of vitamin A.

Can taking vitamin A or beta-carotene supplements help prevent cancer?

Not. It is not recommended to take vitamin A or beta-carotene supplements to prevent cancer. Some research has shown that in some cases taking supplements can increase the risk of developing certain types of cancer.
