Onions are still considered a modern day preventative. Sweet Onions are a member of the 500-plus allium family. While garlic, another allium, has been highly touted as a cancer preventative, most people consume far greater quantities of Onions. As Americans search for low-fat, low-salt, but tasty meals, they're eating more Onions - almost 18 pounds per person per year, which is 50% more than a decade ago. There is great confidence that the Onion will be a key in producing long-term health benefits. In addition to tasting great, Onions contain 25 active compounds that appear to inhibit the growth of cancerous cells, help combat heart disease, inhibit strokes, lower blood pressure & cholesterol, and stimulate the immune system. Alliums are also antibacterial and anti-fungal, so they can help ward off colds, and relieve stomach upset & other gastrointestinal disorders. What makes them so good for you?
