Soy is still widely perceived to be a “health food” in the United States, raking in some $4 billion a year. In the United States, every part of the soybean is used for profit, including soy lecithin -- the waste left over after a soybean is processed -- and soy protein isolate, which was initially invented to be used to make cardboard.
Many people consume soy because of claims that it can reduce the risk of heart disease, alleviate symptoms of menopause, lower cholesterol and even cut your risk of cancer.
But in reality, as Mary Vance describes in the important essay linked below, when people consume soy products it can eventually lead to health problems ranging from digestive upset and bloating to hormonal disruption. And among infants, the estrogens in soy formula can be devastating, causing problems in their brains, reproductive systems and thyroid glands.
There are 100 years worth of studies demonstrating that soy products can be hazardous to your health, but soy is nonetheless now everywhere in our food supply, often hidden in processed foods.
