Smaller Belly, Less Deli May Reduce Kidney Disease Risk, Study Finds11/01/13
FRIDAY, Nov. 1 (HealthDay News) -- Losing belly fat and limiting
processed foods and other sources of dietary phosphorus might help
reduce your risk of kidney disease, a new study finds.
Phosphorus is added to many processed foods to enhance their
flavor and extend their shelf life. High levels of phosphorus are
also naturally found in animal, dairy and vegetable proteins, said
study leader Dr. Alex Chang, of Johns Hopkins University in
The study of nearly 500 overweight or obese adults enrolled in a
healthy-lifestyle program found that a shrinking waistline and
lower consumption of dietary phosphorus were associated with
reduced levels of protein in the urine (albuminuria), which is an
early sign of kidney disease.
After six months, participants' waistlines shrunk an average of
1.7 inches and they had a 25 percent reduction in urine protein.
The researchers also found that a 314-milligram reduction in
phosphorus excretion resulted in an 11 percent decrease in urine
The study appeared in the November issue of the
American Journal of Kidney Diseases.
Other studies have suggested that weight loss may slow kidney
disease progression, but this is the first research study to
support losing belly fat and limiting phosphorus consumption as a
possible way to prevent kidney disease from developing in the first
place, Dr. Joseph Vassalotti, chief medical officer at the National
Kidney Foundation, said in a foundation news release.
"A good rule of thumb is that if the food comes in a package, it's likely to be high in phosphorus," he said. "Approximately 90 percent of phosphorus additives are absorbed by the body."
To limit phosphorus consumption, look for the root letters
"PHOS" on food labels. But phosphorus isn't always listed on food
labels, Vassalotti said, so you need to know likely sources. They
- Processed foods such as dark colas, cereals and flavored
- Dairy products such as cheese, milk, cream, ice cream and
- Animal protein such as deli meats, organ meats, meat
tenderizers, oysters and sardines
- Dried beans, lentils, peas, nuts and seeds (including peanut
butter and other nut butters), cocoa (including chocolate-based
drinks and puddings)
