Spotlight on Vitamin A!
- It is a fat-soluble vitamin (meaning it needs fat to help the body absorb it) stored in the liver.
- It is an essential micronutrient which the body cannot make, so we need to get it from our diet.
- It has an essential role in eye/vision health, body growth, immune function, and reproductive health.
- It is a key part of our immune system, stimulating production and activity of white blood cells.
- Deficiency causes increased chance of infections, hair loss, skin problems, and night blindness.
- There are 2 forms of Vitamin A we can get in our diet:
- Preformed (retinol)
- Pro-vitamin A carotenoids (alpha-carotene & beta-carotene which body turns into retinol)
- Retinol is found in:
- Animal-sourced foods (e.g. fish, liver, eggs, cheese, and butter)
- Fortified foods (e.g. cereals and milk)
- Supplements (NOTE: Upper limit to avoid toxicity is 3,000 iu)
- Carotenoids are found naturally in plant foods (e.g. fruits, vegetables, beans, and whole grains). Naturally RED and ORANGE foods are sources of beta-carotene!
