Studies have shown that people with raised blood cholesterol levels who ate soy products instead of half or all of the animal protein in their diet, reduced their blood cholesterol by 8 to 16 percent in a few weeks. Researchers attribute this to the particular balance of fiber, fatty acids, and phytoestrogens in soybeans, which help deactivate and remove dangerous LDL cholesterol from the body. Soybeans also contain alpha-linolenic acid, an omega-3 fatty acid linked to improved heart health.
High-Fiber Benefits
Soybeans, tofu, tempeh, and other soy products are rich in both soluble and insoluble fibers. Soy fiber improves digestion and can prevent and ease constipation, thereby reducing the risk of colon cancer and other bowel diseases.
Soy fiber also helps regulate blood sugar levels. By slowing down the speed of digestion and absorption, fiber fosters a steadier rise and fall of blood sugar, which benefits diabetics and stabilizes energy levels.
Women and Soy
