Phytoestrogens
Most of us are familiar with nutritional compounds like carbohydrates, proteins and a variety of vitamins as well as the value of eating nutrient rich vegetables and fruits. Few of us are familiar with phytoestrogens even though they too can yield health benefits and are found in plants consumed by us. More detailed information about phytoestrogens can be found at wikipedia and this website.
A Biocompare article entitled 'Higher Consumption Of Some Soy Products, Grains And Vegetables Linked To Reduced Risk Of Lung Cancer' reveals that increased phytoestrogen consumption could reduce the risk of getting lung cancer. Part of the article, which explains both the compound phytoestrogen and its possible benefits, follows.
"Phytoestrogens are plant-derived nonsteroidal compounds found in soy products, grains, carrots, spinach, broccoli, and other fruits and vegetables, according to background information in the article. They have weak estrogen-like activity. The three main classes of phytoestrogens are isoflavones, lignans, and cumestrans. A fourth group of plant-derived steroidal compounds believed to have estrogenic properties are the phytosterols. Phytoestrogens have been shown to have a protective effect against some solid tumors, but there has been little epidemiologic research focused on dietary intake of phytoestrogens and lung cancer risk.
"Our main findings were that patients with lung cancer tended to consume lower amounts of phytoestrogens than controls, that there were sex-specific differences both in intake and in protective effects, and that the apparent benefits were evident in both never and current smokers but less so in former smokers," the authors report.
Reduction in lung cancer risk tended to increase with increasing phytoestrogen intake. "The highest quartiles of total phytosterols, isoflavones, lignans, and phytoestrogens were each
associated with reductions in risk of lung cancer ranging from 21 percent for phytosterols to 46 percent for total phytoestrogens from food sources only," the authors write."
