Vitamin A Benefit #1

Eye Health
Vitamin A plays an important role in keeping your eyes healthy.
How Vitamin A Helps Vision

Your body gets Vitamin A from your diet. Vitamin a gets converted into rhodopsin. Rhodopsin is used by your rod cells in your retina. The retina turns light into signals for your brain to interpret.

Vitamin A Benefit #2

Cancer Risk
A diet rich in Vitamin A has been linked with a lower risk of breast cancer. However, clinical trial results remain mixed.
Vitamin A Levels & Cancer Risk

A pooled analysis of eight cohort studies found that Vitamin A levels in your blood correlate with your risk of breast cancer. Having a lot of vitamin A in the form of β-carotene correlates with a 17% lower risk of breast cancer. Having a lot of total carotenoids, which includes the pigments found in vegetables, correlates with a 19% lower risk of breast cancer.

Data Source

"In this large pooled analysis with more than 3000 case subjects, we observed statistically significant inverse associations between circulating levels of individual and total carotenoids and breast cancer risk. "
