Study questions benefits of reducing sodium in diet
Tuesday, November 15th, 2011Copenhagen, Denmark (AHN) – Health experts have long touted a low sodium diet for the masses, maintaining that reduced sodium lowers the risk for heart disease and stroke.
However, new research published online Nov. 9 in the American Journal of Hypertension, finds that cutting back on salt may increase levels of cholesterol, triglycerides and other risk factors for heart disease. It is not yet clear what the findings mean for long-term health.
The Danish researchers found that less salt did lower blood pressure in whites, blacks and Asians who had either normal or high blood pressure.
But it came with significant increases in levels of cholesterol, triglycerides, the enzyme renin (involved in regulating blood pressure) and the hormones noradrenaline and adrenaline, which can both affect blood pressure and heart rate.
For decades, health experts have advocated reducing sodium consumption. In addition, there has been a powerful new government push to reduce the amount of salt in prepared, processed and restaurant foods.
New U.S. dietary guidelines recommend that people ages 2 and older limit daily sodium intake to less than 2,300 milligrams. People aged 51 and older, blacks and anyone with high blood pressure, diabetes or chronic kidney disease should consider limiting their daily sodium intake to 1,500 mg.
The American Heart Association believes the 1,500 milligrams a day recommendation should be standard for all Americans.
While the new findings are being reviewed, health experts say the recommendation for the general public remains the same when it comes to salt: less is probably better.
