Low potassium linked to high blood pressure
Date:11/8/2008

" according to Dr. Hedayati.

Research performed in the laboratory of Dr. Chou-Long Huang, a co-author of this study, has found evidence that a specific gene, called WNK1, may be responsible for potassium's effects on blood pressure. "We are currently doing more research to test how low potassium in the diet affects blood pressure through the activity of this gene," adds Dr. Hedayati.

The conclusions are limited by the fact that people in the Dallas Heart Study weren't following any specific diet. The researchers are currently performing a study in which participants are on fixed potassium diets while measuring the activity of the WNK1 gene to see if WNK1 is responsible for this phenomenon.

Meanwhile, they urge efforts to increase the amount of potassium in the diet, as well as lowering sodium. "High-potassium foods include fruits such as bananas and citrus fruits and vegetables," says Dr, Hedayati. "Consuming a larger amount of these foods in the diet may lower blood pressure."
