Finally, a study that says it’s OK to lick every grain of salt from the rim of your margarita.
As long as you don’t go overboard.
A massive, four-year research effort by the Population Health Research Institute, McMaster University and Hamilton Health Sciences, Ontario, Canada, supports the accepted doctrine that too much salt is bad for your health.
But it also indicates that too little may be harmful as well.
The four-year study, of more than 100,000 people in 18 countries, confirmed that consuming more than 5,000 milligrams of sodium a day contributes to high blood pressure, increasing the risk of cardiovascular disease and stroke.
But the blood-pressure effects are less at average levels (3,000 mg to 5,000 mg a day) and aren’t evident at levels of consumption below 3,000 mg, the researchers found.
In crunching the numbers, while the researchers found that low sodium intake was not tied to high blood pressure risk, those who consumed more or less than the recommended range saw increased health risks for cardiovascular conditions.
