Dietary Seaweed and Early Breast Cancer: A Randomized Trial
Abstract
The purpose of this research is to investigate whether eating brown seaweed (Undaria pinnatifida) and soy powder can influence hormone levels that are thought to affect breast cancer risk. Brown seaweeds and soy foods are popular in Japan, where the incidence of breast cancer is about 1/6 the rate of that reported for American women. In several animal studies of diet and cancer, adding seaweed or soy to the normal diet resulted in longer healthy lives. Many studies have found that soy consumption in Asia appears to be linked directly to lower breast cancer risk, and laboratory studies have confirmed that soy reduces tumors in animal models. Constituents of soy have been proposed as antiestrogens and antioxidants, may induce apoptosis, and inhibit topoisomerase and angiogenesis (Zheng, 1999). We want to investigate how eating seaweed and soy together might affect hormone levels predictive of women's health. We will use commercially available seaweed and soy powder. These seaweeds and soy powder are commonly found in health food stores.
