Vitamin A Health - it's A1 for eyesight!
Let's looka at Vitamin A health facts. Vitamin A is also known as retinol and is supplied mainly from animal based foods, although some plant based foods supply beta carotene which is converted to vitamin A in the body.
Known commonly as the eye vitamin, it helps the eyes adjust to light changes. It also helps keep the eyes, skin and mucous membranes moist. It helps fight against cancer and is a good anti oxidant as it neutralises free radicals, causing cellular damage.
As with all vitamins, only a little is necessary - too much can be positively harmful. Vitamins A, D and E are fat soluble and are stored in the adipose tissue for between a few days and up to six months. An excess will be stored in the liver and sometimes causes problems. Therefore, do not exceed the stated dose. Note too that it can be lost during food preparation and cooking.
Food rich in this vitamin include:
yellow vegetables, broccoli, fruits, fortified milk and cheese, pork, egg yolk and fish
