Thanks to its many benefits, vitamin A helps fight against aging.

Bone health, eye health, cancer risk… We explain how vitamin A can help you live longer in good health.

What are the sources of vitamin A?

The vitamine A is a fat-soluble vitamin, meaning it is soluble in fats. It is absorbed at the same time as lipids from meals by the small intestine.

It is found in foods of animal origin in the form of retinol (active form of vitamin A): red meats, white meats, eggs, fish, dairy products.

It is also found in foods of plant origin but in the form of provitamins (precursors of vitamin A). Beta-carotene is a precursor of vitamin A. It transforms into active vitamin A once absorbed by the small intestine.

The foods richest in beta-carotene are carrots, sweet potatoes, mango, spinach and even pumpkin.

Vitamin A protects the eyes

Vitamin A is essential for eye health. It is necessary for converting intense light into an electrical signal that can be sent to the brain.

Moreover, one of the first symptoms of a vitamin A deficiency is difficulty seeing clearly in the dark, also called nyctalopia.

Good intakes of vitamin A can help combat age-related decline in vision. They help reduce the risk of age-related macular degeneration (AMD).

Reduced risk of certain cancers

Vitamin A plays an important role in the growth and development of our cells. Its possible protective effect against cancer is a subject studied by many scientists.

According to several observational studies, regularly eating foods rich in beta-carotene may help reduce the risk of certain cancers such as Hodgkin’s lymphoma, lung cancer, bladder cancer and cervical cancer.

This reduction in cancer risk is linked to the fact that vitamin A participates in the process of healthy cell division.

An essential nutrient for healthy bones

The nutrients needed to keep bones healthy are protein, calcium and vitamin D. But less talked about is vitamin A, which is just as necessary for bone growth and development.

Indeed, it has been scientifically suggested that poor bone health may be linked to a deficiency of vitamin A. People with low levels of vitamin A in their blood are at greater risk of fractures compared to people who eat a diet rich in vitamin A.

A major advantage when we know that older people are more prone to falls and fractures, but also to osteoporosis.
