Can vitamin A turn back the clock on breast cancer?
A derivative of vitamin A, known as retinoic acid, found abundantly in sweet potato and carrots, helps turn pre-cancer cells back to normal healthy breast cells, according to research published this month in the International Journal of Oncology. The research could help explain why some clinical studies have been unable to see a benefit of vitamin A on cancer: the vitamin doesn’t appear to change the course of full-blown cancer, only pre-cancerous cells, and only works at a very narrow dose.
