A new study found that pears are associated with lower body weight. People who consume pears are 35 percent less likely to be obese, scientists discovered.

The study also found that pear consumption is associated with higher diet quality. Pears are an excellent source of fiber, in addition to being a good source of vitamin C.

A single medium pear contains nearly 24 percent the daily fiber recommendations — and is only 100 calories. The fruit is free of fat, cholesterol and sodium and contains 190 mg of potassium.

Researchers from the Louisiana State University looked at data from 2001 to 2010 for the study. They used a nationally representative sample to analyze the association of fresh pear consumption with nutrient intake, nutrient adequacy, diet quality and cardiovascular risk factors in adults.

Dr. Carol O’Neil, who led the study, said, “The association between pears and lower weight is very exciting. We believe fiber intake may have driven the lower body weights that were seen in this study.”

She added, “There was no difference in energy intake or level of physical activity found between the fresh pear consumers and non-consumers.”

Eating one medium fresh pear each day has a positive effect on nutrient intake.

The fruit has higher percentages of fiber, vitamin C, magnesium, copper and potassium.

Consumers of fresh pears also have lower intakes of total, monounsaturated fatty acids, saturated fatty acids and added sugars.

According to the USDA Guidelines for Americans, people who eat more fruit as part of an overall healthy diet are more likely to reduce their risk of chronic diseases.

But, the researchers noted that little has been published on the health outcomes associated with individual fruits — including pears.

The study was published in Nutrition and Food Science.

一项最新的研究称，梨与体重减轻有某种相关性。科学家发现，吃梨的人，其肥胖的概率比不吃的人低35%。

该研究还发现，吃梨可以提高膳食质量。梨除了富含维C，还是非常好的纤维食物。

一个中等大小的梨含有人体每天所需纤维的约24%，而卡路里含量只有100。

梨不含脂肪、胆固醇和钠 — 但含有190毫克的钾。

路易斯安那州立大学的研究人员从2001年到2010年对此进行研究。

他们从全国抽取试验样本，分析成年人食用鲜梨与营养摄入、营养充足性、膳食质量和心血管疾病之间的关系。

卡罗· 奥尼尔博士主持研究。她说：“梨与减重之间的关系让人十分兴奋。我们相信摄入纤维是本项研究中减重的原因。”

她补充道：“在吃梨与没有吃梨的人之间，没有能量摄入或体力活动方面的差异。”

每天吃一个中等大小的鲜梨对营养吸收非常有益。

梨这种水果富含纤维素、维生素C、镁、铜和钾。

食用鲜梨也会降低人体对总脂肪酸、单不饱和脂肪酸、饱和脂肪酸和添加糖的吸收量。

根据美国农业部（USDA）向美国居民发布的饮食指南，多吃水果作为健康饮食一部分的人更不容易得慢性疾病。

但研究人员指出，很少有人发表文章关注人类健康与单一某种水果（包括梨）之间的联系。

该研究成果发表在《营养与食品科

学》期刊上。
