Most of our serious illnesses and deaths in the U.S. now come from preventable diseases, such as heart disease. But we know what works to improve health.
如今美国出现的严重疾病和死亡大多是可以预防的，例如心脏病 。我们知道怎样有效地改善健康 。
A new report recommends 43 changes that can make big improvements. To arrive at their recommendations, researchers reviewed more than a thousand studies of public health. Their findings are in the American Heart Association journal Circulation.
一项新的研究报告推荐了43种效果显著的改变 。为了验证他们的建议，研究人员审查了一千多项关于公共健康的研究 。研究成果发表在美国心脏协会的期刊上 。
Some of the suggestions, such as tightening restrictions on smoking, are already paying off in many areas. Others, such as increasing taxes for unhealthful foods, might face stiff opposition, but could pay off large dividends in health savings later.
其中一些建议已经在许多地区取得成功，例如严格限制吸烟 。其它的建议可能遭到坚决的反对，例如增加不健康食品的税收，但是却能抵消健康储蓄的大笔利息 。
But some surprisingly simple suggestions could be easiest to institute. Try extending the hours for public parks and schools' recreation facilities. Or improving sidewalks and visual appeal of neighborhoods to make people want to walk, bike or run there more often. The authors of the paper argue that the next step is just for policy makers to put these changes into action.
但是，一些简单得令人吃惊的建议可能最容易着手实施 。试着花更多时间在公园和学校的娱乐设施上 。或者改善社区的人行道和视觉吸引力，让人们愿意经常在这里散步，骑自行车或者跑步 。本文作者认为下一步就是让政策制定者将这些改变付诸实施 。
