Phytoestrogens are food sources that provide targeted health benefits over and above the basic nutritional value found in other foods. Some have been shown to preempt aging, particularly in the case of age-related diseases. For example the isoflavones, which are a major class of phytoestrogens and lignans, which are another major class, have been studied and shown to reduce the risks for heart disease, osteoporosis and certain cancers for the folks that consumed them. Lignans are found in significant quantities in a variety of foods including whole grains, vegetables, legumes and berries. Lignans are found in flax seeds and sesame seeds, too. The lignans in sesame seeds provide a synergistic effect with vitamin E to provide an anti-aging effect.
One study in the British Isles found that men with the highest consumption of lignans had the lowest incidence of prostate cancer. Parallel studies in Europe of postmenopausal woman who consumed a greater amount of lignans in their diet showed a reduced risk of breast cancer. A similar result was found in the case of pre-menopausal women; those with the highest consumption of lignans showed the lowest risk for breast cancer. This is good news for seniors, both women and men, who are looking for dietary means to preempt aging and improve their senior health.
