O sal faz mal

Shaving 3 grams off the daily salt intake of Americans could prevent up to 66,000 strokes, 99,000 heart attacks and 92,000 deaths in the United States, while saving $24 billion in health costs per year, researchers reported on Wednesday.

The benefit to the U.S. population would be comparable to cutting smoking by 50 percent, significantly lowering obesity rates and giving cholesterol drugs to virtually everyone to prevent heart attacks, said Dr. Kirsten Bibbins-Domingo of the University of California, San Francisco and colleagues.

Salt, which contributes to high blood pressure and heart disease, is widely overused in the United States, with 75 to 80 percent coming from processed food. Men typically consume 10.4 grams per day. For women, the average is 7.3 grams. Its use is rising.
