There's good reason for the hype. Soy is rich in high-quality protein. It is also low in saturated or "bad" fats and high in "good" fats such as omega-3 fatty acids - which may reduce the risk of chronic disorders such as heart disease and some types of cancer. Soy is also a vitamin and mineral powerhouse, often containing calcium, iron, fibre and vitamin B. And it is rich in phytochemicals - naturally occurring compounds found in plants. Of particular interest to menopausal women are isoflavones - a group of phytochemicals, which some studies have shown may help regulate fluctuating estrogen levels while reducing the instances of hormonal ailments such as hot flashes, breast cancer and osteoporosis.
