Smoking causes many kinds of cancer, not just lung cancer.

Why do some people get lung cancer -- even if they never smoke?
According to the Centers for Disease Control (CDC), lung cancer is the number one cause of cancer deaths worldwide. The American Thoracic Society points out that over 75 percent of lung cancers are non-small cell lung cancers (NSCLC) and have an average overall 35-year survival rate of only 14 percent. Previous research has shown that about 90 percent of NSCLC appear to be activated by specific signaling pathways in lung tissue.

New research suggests eating a lot of processed foods containing inorganic phosphates could actually stimulate those same cancer-triggering pathways. In research published in the American Journal of Respiratory and Critical Care Medicine, published by the American Thoracic Society, scientists from Seoul National University conclude that a diet high in inorganic phosphates, which are found in a host of processed foods including meats, cheeses, beverages, and bakery products, might spur the growth of lung cancer. The researchers also suggest the food additive may contribute to the development of malignancies in people predisposed to lung cancer.

While living organisms need a moderate level of phosphate, the use of inorganic phosphates as a food additive to increase water retention and improve food texture artificially has soared over the past decade. That means the average American diet is loaded with excess amounts of phosphates. "In the 1990s, phosphorous-containing food additives contributed an estimated 470 mg per day to the average daily adult diet. However, phosphates are currently being added much more frequently to a large number of processed foods, including meats, cheeses, beverages, and bakery products. As a result, depending on individual food choices, phosphorous intake could be increased by as much as 1000 mg per day," Dr. Cho explained in the media statement. [, Viewzone]
