Older women who take potassium citrate supplements can increase their bone density, reducing the risk of osteoporosis, according to new research appearing in the Journal of the American Society of Nephrology.Dr. Reto Krapf of the University of Basel in Switzerland and colleagues conducted a study of 161 post-menopausal women whose average age was 59. Krapf split the women into two groups: The first received a daily supplement of potassium citrate for up to 12 months, and the second was given a dailysupplementof potassium chloride for up to 12 months.
The researchers hoped to prove thatpotassiumcitrate -- a base chemical -- could raise acidicbodypH in the participants, which is generally caused by poor lifestyle and dietary choices. Potassium chloride was used in the control group because it is a neutral chemical that does not affect body pH.
After six to 12 months, the researchers conductedbone mineral densitytests on the participants' lower spine andhips. The group taking the potassium citrate (base)supplementsexperienced a one percent increase inbonemineral density in the lumbar spine area, as well as a one percent increase inbone densityin the hips. Conversely, the group taking the potassium chloride (neutral) experienced a one percent loss of bone density at both test sites.
"Both the spine and hip are critical regions whereosteoporosisand low bone mass result in debilitating fractures," according to the American Society of Nephrology.
The researchers also found that thewomentaking potassium citrate lost lesscalciumthrough their urine than those taking potassium chloride.
According to Krapf's team of researchers, the typical Americandietis far too high in acidic foods that lower the body's pH, including dairyproducts, refined grains and meat products. An acidic body pH forces the body to pullalkalinecalcium from the bones to help buffer the high levels of acid, which results inbone lossand can cause otherhealthdisorders such as cancer.
Americans also consume too few alkaline foods, such as fresh, raw fruits and vegetables, which raise the body's pH to healthier levels, Krapf said.
Nutritionist and consumer advocate Mike Adams recommendsconsumersavoid processed foods and beverages -- especially colas and other sugary sodas -- to prevent bone loss. Consumers can research healthynutritionoptions on Adams' free online nutrient database,NutrientReference.com.
