Another New Scientist report states that "New research from Britain and the US, as well as Japan, provides strong evidence that women can substantially reduce the risk of breast cancer by consuming soya bean products, such as soya milk, or tofu."
"Researchers in Cambridge have shown that a diet high in soya protein can alter women's hormones in a way that mimics the anti cancer drug tamoxifen." "Eating soya products can lower the risk of both prostate and colon cancers." "Most natural high fibre foods, such as whole wheat, oats, barley, rye, sesame and flax seeds may have a similar effect."
