An Apple A Day Keeps Kidney Stones Away: More Fruits And Veggies, Less Salt Prevents Stones From Forming

  ScienceDaily (Aug. 14, 2009) — Researchers have found another reason to eat well: a healthy diet helps prevent kidney stones. Loading up on fruits, vegetables, nuts, low-fat dairy products, and whole grains, while limiting salt, red and processed meats, and sweetened beverages is an effective way to ward off kidney stones, according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN).
  Because kidney stones are linked to higher rates of hypertension, diabetes, increased body weight, and other risk factors for heart disease, the findings have considerable health implications.
Eric Taylor, MD (Maine Medical Center) and his colleagues at Brigham and Women’s Hospital conducted a large study to determine the effects of healthy eating habits on the formation of kidney stones. The investigators collected information from individuals enrolled in three clinical studies: the Health Professionals Follow-up Study (45,821 men followed for 18 years), the Nurses’ Health Study I (94,108 older women followed for 18 years), and the Nurses’ Health Study II (101,837 younger women followed for 14 years).
  Dr. Taylor’s team assigned a score to each participant based on eight components of a DASH (Dietary Approaches to Stop Hypertension) style diet: high intake of fruits, vegetables, nuts and legumes, low-fat dairy products, and whole grains and low intake of salt, sweetened beverages, and red and processed meats. Individuals with higher DASH scores consumed diets that were higher in calcium, potassium, magnesium, oxalate, and vitamin C and lower in sodium.
  A total of 5,645 incident kidney stones developed in the participants in the three studies. In each study, participants with the highest DASH scores were between 40% and 45% less likely to develop kidney stones than participants with the lowest DASH scores. The reductions in kidney stone risk were independent of age, body size, fluid intake, and other factors.
  Because a DASH-style diet may affect the development of hypertension, diabetes, and other chronic diseases associated with kidney stones, the researchers also performed an analysis limited to study participants without hypertension or diabetes. Even among those individuals the DASH diet reduced the risk of kidney stones.
  Many of the medications used to treat kidney stones have unpleasant side effects. This study indicates that adopting a DASH-style diet may be an effective alternative.

一天一个苹果,肾结石远离你:多吃水果与蔬菜,少吃盐可预防结石形成。

  科学日报(20090814):研究者发现了健康饮食的另一好处:健康饮食有助于预防肾结石的形成。据美国肾脏病协会杂志(JASN)的最近一期报道称,多吃水果、蔬菜、糙米,低脂饮食,同时限制摄入钠、红肉或加工过的肉类及甜饮料等,可有效预防肾结石的形成。
  因为肾结石与高血压、糖尿病、肥胖及心脏病的其它高危因素有关。这些发现颇有健康启示。
  Maine医学中心的Eric Taylor博士及其在Brigham and Women医院的同事们进行了大量研究,拟探讨健康饮食与肾结石的关系。他们收集了三项临床研究资料,分别为卫生从业人员的随访研究(45821名男性随访了18年)、护理人员健康研究I(94108名老年女性随访了18年)、护理人员健康研究II(101837名年轻女性随访了14年)。
  Taylor博士基于DASH(降压饮食法)式饮食的以下8种主要评分标准对每一位被调查者进行了打分:高摄入水果、蔬菜、营养素、豆类、低脂食物和糙米;低摄入盐、甜饮料及加工类肉制品。那些高DASH得分个体的饮食中钙、钾、镁、草酸盐、维生素C等含量高,而盐的含量较低。
  三项研究中,参与调查的人中一共有5645例患肾结石。每一项研究中,高DASH分值的人群中肾结石的发生率比低DSAH分值的发病率低40-45%。降低肾结石发生有赖于年龄、体重、水果摄入的多少及其它因素。
  因为DASH式饮食可能影响高血压、糖尿病及与肾结石相关的其它慢性疾病。研究者也对无高血压、糖尿病的个体进行了限制性研究。即使在这些人群中,DASH饮食也降低了肾结石的发病风险。
  过去治疗肾结石的许多方法都有令人讨厌的副作用。这项研究显示,改进的DASH式饮食或许是(治疗肾结石的)另一种选择。
