Other interesting substances in food

The latest flash in the nutrition sky is caused by phytochemicals. Phyto is the Greek word for plants, so phytochemicals are simply — yes, you’ve got it —chemicals from plants. Although the 13-letter group name may be new to you, you’re already familiar with some phytochemicals. Vitamins are phytochemicals. Pigments such as beta carotene, the deep yellow coloring in fruits and vegetables that your body can convert to a form of vitamin A, are phytochemicals.
And then there are phytoestrogens, hormone-like chemicals that grabbed the spotlight when it was suggested that a diet high in phytoestrogens, such as the isoflavones found in soybeans, may lower the risk of heart disease and reduce the incidence of reproductive cancers (cancers of the breast, ovary, uterus, and prostate). More recent studies suggest that phytoestrogens may have some problems of their own.
