Vitamin A may reduce the risk of stomach cancer

According to Swedish researchers, taking a lot of vitamin A may help reduce the risk of developing stomach cancer.

Dr. Susanna C. Larsson of Karolinska Institute and colleagues explained in the American Journal of Clinical Nutrition magazine as follows: There are two types of Vitamin A: Vitamin A form like retinol found in foods of animal origin and pre-vitamin A forms like carotenoids in fruits and vegetables.

Researchers looked at records of 82.00 adult Swedes who completed answering questions about eating habits in 1997 and were followed until June 2005.

The average follow-up time is 7 years. During that time, 139 cases of stomach cancer were diagnosed. The group with a rich diet of viatamine A and retinol, and alpha-carotene and beta-carotene are less likely to develop stomach cancer. Compared to the group with the least vitamin A intake, the most vitamin A group had a 50% lower risk of stomach cancer.

Cigarette smoking affects vitamin A's protective effect on stomach cancer, but alcohol seems to make no difference.
