Food Additive Jump-Starts Lung Cancer

"Alarming new research shows that inorganic phosphates, which are commonly added to many processed foods, may accelerate the growth of lung cancer tumors and even trigger the development of tumors in people predisposed to lung cancer. Phosphates are routinely added to food products such as cheeses, meats, bakery products, and beverages in order to improve texture and increase water retention.

The research, which was conducted at Seoul National University and appears in the January issue of the American Thoracic Society’s magazine American Journal of Respiratory and Critical Care Medicine, was carried out with mice. Study leader Myung-Haing Cho, D.V.M., Ph.D., said, “Our study indicates that increased intake of inorganic phosphates strongly stimulates lung cancer development in mice, and suggests that dietary regulation of inorganic phosphates may be critical for lung cancer treatment as well as prevention.”
