Inorganic phosphate, a common food additive can significantly affect your exercise habits, reports a new study. The findings of the study are published in the journal Circulation.
Inorganic phosphate, a food additive, and preservative used in up to 70 percent of food in the American diet, may be contributing to couch potato behavior.

What is Inorganic Phosphate?
Phosphates occur naturally in many foods, including dairy products, meat, fish, and baking powder, but it is the consumption of fast foods, processed foods, and bottled drinks that can push phosphate levels up, said Dr. Wanpen Vongpatanasin.

Find out how food additives for almost every food that you consume come with danger signals and make way into your food and impact your health.
For example, a block of Parmesan cheese contains phosphates, but when Parmesan is sold in a grated or shredded form, additional phosphates may be added to keep it from sticking. When examining food labels, look for anything that contains "phos-," such as calcium phosphate, disodium phosphate, or monopotassium phosphate.
"We should not consume more than 700 milligrams of inorganic phosphate per day, but about one-third of people consume three to four times that amount," said Dr. Wanpen Vongpatanasin, Professor of Internal Medicine and Director of the Hypertension Fellowship Program at UT Southwestern Medical Center. "Like any nutritional ingredient, too little phosphate is harmful, but too much is also harmful."
Adding to the problem is the lack of information on inorganic phosphate. Looking at food labels won't help, Dr. Vongpatanasin said. "Currently there are no mandates or regulations for the food industry to label how much inorganic phosphate is in the food chain."
The new study describing the adverse effects of excess consumption of phosphate is published in the journal Circulation.
Phosphate is plentiful in fruits and vegetables in its organic form, which does not cause problems because it is not absorbed. However, the body readily absorbs inorganic phosphate, and most people are consuming far too much of it. For example, cola drinks, processed meats, and prepared frozen foods typically contain this additive.
When the researchers studied mice that were fed a high-phosphate diet, they found measureable changes in their ability to exercise.
"We measured their oxygen uptake during exercise and found that their capacity for the movement was much lower. The mice were unable to generate enough fatty acids to feed their muscles," Dr. Vongpatanasin said. The researchers also looked for gene changes and found that many genes involved in skeletal muscle metabolism had changed levels after 12 weeks of the high phosphate diet.
In addition, the study analyzed data from participants in the Dallas Heart Study who wore physical activity monitors for seven days. The multiethnic participants, ages 18 to 65, had no kidney or heart problems and were not on medications. Researchers examined blood test results in this group and verified that the response to phosphate in humans was similar to that in mice. Higher phosphate levels were linked to reduced time spent in moderate to vigorous exercise, while sedentary time increased as phosphate levels climbed.
Since inorganic phosphate is widely used in the food supply, the UT Southwestern research team concluded that more studies are needed to further define the broader health impact of this substance. The Food and Drug Administration and the U.S. Department of Agriculture establish requirements for food labels in the U.S.
