Think processed foods are bad for you? Not sure why exactly? One possibility: inorganic phosphates in food might boost the growth of lung cancer.
New research in an animal model suggests that a diet high in inorganic phosphates, which are found in a variety of processed foods including meats, cheeses, beverages, and bakery products, might speed growth of lung cancer tumors and may even contribute to the development of those tumors in individuals predisposed to the disease.
The study also suggests that dietary regulation of inorganic phosphates may play an important role in lung cancer treatment. The research, using a mouse model, was conducted by Myung-Haing Cho, D.V.M., Ph.D., and his colleagues at Seoul National University, appears in the first issue for January of the American Journal of Respiratory and Critical Care Medicine, published by the American Thoracic Society.
"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," said Dr. Cho.
Of course, if you are eating a diet high in vegetables and fruits and low in processed foods you do not need to know why exactly the processed foods are bad for you. Whether this study has identified a real reason to avoid processed foods or not we already know that drinking colas or other sodas isn't good for us and neither is eating processed cheese spread.
