A diet low in salt and meat can dramatically reduce the risk of kidney stones, according to an Italian study that could spell the end for the low-calcium¹ diet that doctors have been recommending for years.

据意大利的一项研究表明，低盐低肉饮食可以显著降低患肾结石的危险，该研究还"终结"了医生已推荐了多年的防肾结石低钙饮食。

About 10% of the U.S. population - and a much larger percentage of men, who make up 80% of sufferers - will have at least one kidney stone sometime in their lives, and it can be excruciatingly painful. Most stones can be excreted, but in about 15% of cases, surgery or shockwave treatment to pulverize² the stones is needed.

美国人口中约有10%至少在一生中某时间患有一侧肾结石，其中男性比例要高得多，占患者的80%，患者有难以忍受的疼痛。大多数肾结石能排掉，但有大约15%的病例，需要动手术或用冲击波治疗才能粉碎肾结石。

Many doctors have told such patients to cut down on calcium because most kidney stones are made of a calcium compound. But recent studies have suggested that such a diet might not prevent kidney stones after all and may even promote them - along with osteoporosis.

许多医生曾告诉这些患者减少钙的摄入，因为大多数肾结石的成份是钙。但是最近的研究已表明，低钙饮食不仅不能预防肾结石，甚至会促使它的生成，还伴有骨质疏松。

The new study "dispelled³ a myth that a low-calcium diet is important in preventing kidney stones," said Dr. David A. Bushinsky, a kidney specialist at the University of Rochester.

罗切斯特大学的肾病专家David A.Bushinsky博士说："这项新研究打破了低钙饮食对防肾结石十分重要的神话。" 

William Keane, president of the National Kidney Foundation, said he is sure the new diet "will become the gold standard."

全国肾脏基金会主席William Keane说他确信新的饮食"将成为金标准"。
