Increasing Potassium in Diet Can Lower Blood Pressure

Tagged:  

Potassium and sodium work in opposition to one another in the body. A decrease in potassium levels causes the body to hold onto sodium and water, and this may increase blood pressure. An increase in potassium causes sodium and water to leave the body, and this may decrease blood pressure. Diets high in potassium are linked to a decreased risk of stroke in people with normal and high blood pressure.

POTASSIUM & Alzheimer's Disease

Tagged:  

A recent study in Archives of Neurology provides evidence that antihypertensives, particularly potassium-sparing diuretics, could reduce the risk of dementia, including Alzheimer's disease (AD).

Commonly known as "water pills" diuretics flush excess water and sodium from the body while avoiding excretion of potassium. Interestingly, age, gender, blood pressure, education, and other variables that could affect the onset of AD had no bearing on the benefits conferred by the potassium-sparing diuretics.

POTASSIUM FOR BONES

Potassium citrate--the kind found in fruits and vegetables--appears to build bone.

Scientists randomly assigned 161 postmenopausal women with low bone density to take 390 mg of potassium, either as citrate or chloride, three times a day. After one year, the women who took potassium citrate had higher density in their spine and hip bones, while those who took potassium chloride lost bone in their spines. (Their hip bone density didn't change.)

Sodium-Potassium Ratio Linked to Heart-Disease Risk

Tagged:  

If you're worried about hypertension, a new study warns that the more sodium from salt in your diet and the less potassium, the greater your risk for heart disease. For people with prehypertension, researchers found that every one-unit increase in the ratio of sodium to potassium excretion was associated with a 24% increase in risk of cardiovascular disease.

Previous research has established separately that higher sodium and lower potassium intake both appear associated with high blood pressure, a known risk factor for cardiovascular disease.
