37 The Benefits of Cutting Salt 减少盐分摄取量的益处

①Just when you had figured out how to manage fat in your diet,researchers are now warning against another common mealtime pit-fall—salt.

②A study by researchsers at the University of California,San Francisco(UCSF),Stanford University and Columbia University shows that even a modest decrease in daily salt intake can lead to dramatic health benefits.The authors documented an annual drop of as many as 120,000 cases of heart disease,66,000 instances of stroke and 99,000 heart attacks caused by high blood pressure after a 3-g-per-day reduction in salt.

③The advantage,not surprisingly,were greater for African Americans,who are more likely to develop high blood pressure than other ethnic groups,and for the elderly,since blood vessels stiffen with age,which can lead to higher blood pressure.

④"Everyone in the U.S. is consuming salt far in excess of what is good for them,"says lead author Dr. Kristen Bibbins-Domingo of UCSF."what we are suggesting is that a population-wide effort to reduce salt intake,even slightly,will have health benefits."

⑤The team conducted a computer-based analysis to determine the impact of a 3-g-per-day reduction in salt intake on rates of heart disease and death.They also calculated the cost savings emerging from the amount of disease that would be avoided because of lower blood pressure.The conclusion:by cutting salt intake nationwide,the U.S. could save $10 billion to $24 billion annually in health care costs.
