Lung Cancer Risk May Be Increased By Inorganic Phosphates in Processed Foods

Lung cancer is most heavily linked with smoking, and, increasingly, also to air pollution, which is a worsening problem in most developed cities.

Yet, just like how food, diet and nutrition play a part in the development of skin cancer (and not just sunburn) and other cancers, so it is the case for lung cancer. And a recent study has highlighted a possible link between lung cancer and processed foods, as discussed in Sherry Baker’s article below.

Processed Foods Linked to Lung Cancer

by Sherry Baker

(NaturalNews) Why do some people get lung cancer – even if they never smoke? New research suggests eating a lot of processed foods containing inorganic phosphates could be the explanation. What’s more, the study also suggests that dietary changes to avoid these chemical additives may play an important role in lung cancer treatment.

In research just published in the January issue of 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.

Myung-Haing Cho, D.V.M., Ph.D., and his colleagues studied mice with lung cancer tumors for four weeks. The rodents were randomly assigned to eat a diet of either 0.5 or 1.0 percent phosphate, a range roughly equivalent to what’s found in most modern human diets that contain processed foods. At the end of the study period, the animals’ lung tissues were analyzed to see what effects the inorganic phosphates had on tumors.

“Our results clearly demonstrated that the diet higher in inorganic phosphates caused an increase in the size of the tumors and stimulated growth of the tumors,” Dr. Cho said in a statement to the press. “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.”
