Previous studies have shown that whole grains can boost bone mineral density, lower blood pressure, promote healthy gut bacteria and reduce the risk of diabetes.

此前的研究显示粗粮能增加骨骼中的矿物密度，降低血压，增加健康的肠道细菌，以及降低患糖尿病的风险。

One particular fibre found only in oats – called beta-glucan – has been found to lower cholesterol which can help to protect against heart disease. A bioactive compound called avenanthramide is also thought to stop fat forming in the arteries, preventing heart attacks and strokes.

一种只有燕麦才有的纤维素——称为β-葡聚糖——能降低胆固醇，从而预防心脏疾病。燕麦中的一种生物活性物质，被称为燕麦生物碱，能防止动脉中形成脂肪，减少心脏病和中风的威胁。

Whole grains are also widely recommended in many dietary guidelines because they contain high levels of nutrients like zinc, copper, manganese, iron and thiamine. They are also believed to boost levels of antioxidants which combat free-radicals which are linked to cancer.

很多饮食指南都极力推荐粗粮，因为其营养价值高，富含锌、铜、锰、铁和维生素B1。粗粮还可以增加身体内的抗氧化物质，来对抗可能引起癌症的自由基。

The new research suggests that if more people switched to whole grains, thousands of lives could be saved each year. Cancer kills around 160,000 people a year while coronary heart disease is responsible for around 73,000 deaths in the UK each year.

此次的新研究表明，如果更多的人选择食用粗粮，每年可能拯救成千上万的生命。英国每年有大约16万人死于癌症，大约7.3万人死于冠心病。

Health experts said the study proved that whole grains were essential for good health.

健康专家称研究证明粗粮对健康非常重要。

The researchers recommend that people choose foods that are high in whole grain ingredients—such as bran, oatmeal, and quinoa—that have at least 16 grams per serving, while reducing consumption of unhealthy refined carbohydrates. Each 16 gram serving lowered the risk of total death by seven percent, and cancer by 5 percent.

研究人员建议人们选择粗粮成分含量高的食物，如米糠，燕麦片，藜麦——每份至少含有16克；同时减少食用不健康的细粮碳水化合物。每吃16克粗粮可降低7%的总死亡率，以及5％的癌症死亡率。英文来源：每日电讯报（中国日报网）
