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.
如今美國出現的嚴重疾病和死亡大多是可以預防的，例如心臟病。我們知道怎樣有效地改善健康。
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.
一項新的研究報告推薦了43種效果顯著的改變。為了驗證他們的建議，研究人員審查了一千多項關于公共健康的研究。研究成果發表在美國心臟協會的期刊上。
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.
其中一些建議已經在許多地區取得成功，例如嚴格限制吸煙。其它的建議可能遭到堅決的反對，例如增加不健康食品的稅收，但是卻能抵消健康儲蓄的大筆利息。
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，一些簡單得令人吃驚的建議可能最容易著手實施。試著花更多時間在公園和學校的娛樂設施上。或者改善社區的人行道和視覺吸引力，讓人們愿意經常在這里散步，騎自行車或者跑步。本文作者認為下一步就是讓政策制定者將這些改變付諸實施。
