There are a lot of health-related phytochemicals in soy. Protein kinase inhibitors help keep cell growth and activity normal. Phytosterols and saponins help regulate cholesterol. Phenolic acid and phytates are antioxidants. Then there are the isoflavones, which are weak phytoestrogens estrogen-like compounds found in plants.

Isoflavone levels vary in different types of tofu and soy milk products. So if the weak soy substance replaces the natural high-strength estrogen in cells, then maybe the soy will protect against cancers that would prefer a stronger estrogen signal.
