The isoflavones in soy products have estrogen-like effects and can stimulate the growth of breast glands, but these phytoestrogens are absorbed less after digestion and therefore have little effect on people. According to a study by Dr. Helen Wiseman, a nutritionist at the Royal College of London, phytoestrogens in soy products can stimulate breast growth. According to research by Dr. Helen Wiseman, a nutritionist at the Royal College in London, soy protein prepared by Oriental cooking methods contains a chemical component that apparently has the same effect as triamcinolone acetonide. Triamcinolone is widely used to treat breast cancer in women. This may also account for the low incidence of breast cancer in people who consume large amounts of soy products. It is thought that triamcinolone also prevents heart disease and osteoporosis. This bioactive substance also acts as an antioxidant, which is probably another reason why soy products can prevent cancer and heart disease. Investigations in Singapore have also demonstrated that normal consumption of soy products can reduce the incidence of breast cancer.
