Women whose mothers consumed canola oil during pregnancy and breast-feeding may be less likely to develop breast cancer than those whose mothers consumed corn oil, a new study suggests.
Researchers fed pregnant and lactating mice a diet high in either corn oil, which contains 50 percent omega-6 polyunsaturated fats, or canola oil, which contains only 20 percent omega-6 polyunsaturated fats. Canola oil also has a much greater percentage of omega-3 polyunsaturated fat -- 10 percent compared with 0.5 percent in corn oil.
The study, expected to be presented Tuesday at the American Association for Cancer Research's annual conference, found that pregnant and lactating mice fed the corn oil diet gave birth to females with a greater risk of developing breast tumors than those who ate the diet higher in canola oil.
