Investigate and measure antioxidant activity of foods.

There is considerable scientific evidence suggesting that diet affects the incidence of breast cancer. Those who consume a lot of fruits and vegetables are believed to have a low incidence of breast cancer. Research sponsored by the U.K. Ministry of Agriculture Fisheries and Food (MAFF, Food and Veterinary Science Div., Room G8, Nobel House, 17 Smith Square, London SW1P 3JR, England, U.K.) at the Patterson Institute of Research (Manchester) is focusing on whether dietary antioxidants and phytoestrogens can inhibit the proliferation of breast cells that may lead to breast cancer.
