Five Reasons To Avoid Soy
The soybean is heavily consumed all around the world and has been reported as being healthy, including the U.S. Food and Drug Administration claiming it reduces the risk of heart disease; however, new research links soy consumption with potential health dangers.
1. Soy Contains Chemical Toxins
Most soy consumed today is not organic, and contains high amounts of pesticide and herbicides that are used to ensure a good crop yield. Pesticide and herbicides are chemicals designed to kill the bugs and weeds surrounding a crop, but are extremely hazardous to environmental and human health. Research from the University of North Dakota showed a link between pesticide exposure and the development of neurological disease.
2. Soy May Alter Hormone Function
Soy contains a plant compound called genistein that has shown evidence for disrupting the balance and effects of estrogen in the body. The National Institute Of Environmental Health Sciences says too much genistein may reduce fertility in women, trigger early puberty and disrupt development of fetuses and children. A study published in the journal Reproductive Toxicology on female mice found that genistein led to reduced fertility and abnormal embryo development. Another study found that female rats fed high amounts of genistein developed irregular estrogen cycles, experienced early puberty and produced smaller litters. It was also found that male rats fed high doses of genistein developed abnormal breast cell growth.
3. Soy May Promote The Development Of Certain Cancers
A study done in the journal Plant Foods and Human Nutrition found that rats fed raw soy flour developed a growth of pancreatic cells, and eventually tumors on their pancreas. One study conducted by the American Association of Cancer Research found that soy protein consumed by women increased chances for developing epithelial hyperplasia, a small growth of cells containing the risk of developing into cancer. Another study done in the journal Environmental Health Perspectives found that genistein in soy stimulated breast cells to enter into the cell cycle, the process in which they divide, increasing the risk of developing cancer.
4. Soy May Alter Thyroid Function
A study in Japan found that consuming only two tablespoons of soybeans per day for one month caused an increase in a thyroid-stimulating hormone, responsible for regulating the function of the thyroid gland. Another study done by the American Journal Of Clinical Nutrition found that only five grams of soy protein consumed by premenopausal women offset hormones that are required for healthy thyroid function for a total of three months.
5. Soy May Cause Dementia
A study done by the Journal of the American College Of Nutrition found that men who consumed at least two servings of tofu (from soy) a week had reduced cognitive test performance, and a greater indication later in life of Alzheimers disease and dementia.
