Vitamin A-rich diet may reduce stomach cancer risk
A diet rich in vitamin A (retinol) may cut the risk of stomach cancer by 44 per cent, suggests a prospective study from Sweden.
The study, which analyzed dietary data from over 36,000 women and 45,000 men, also reported that similar risk reductions are obtained from high dietary intake of both alpha- and beta-carotene.
High intakes of vitamin A, retinol, and provitamin A carotenoid may reduce the risk of gastric cancer. Stomach cancer is the fourth most frequent cancer in the world, according to the European School of Oncology, and there are 800,000 new cases every year. It is Japan's most common form of cancer.
Writing in the current issue of the American Journal of Clinical Nutrition, the researchers report that, the relative risk of gastric cancer between people in the highest versus lowest intake groups of total vitamin A was reduced by 47 per cent.
The relative risks between people in the highest versus lowest intake groups of retinol, alpha-carotene and beta-carotene were reduced by 44, 50 and 45 per cent, respectively.
No significant gastric cancer risk reduction associations were found for beta-cryptoxanthin, lutein and zeaxanthin, or lycopene intake, said the researchers
