Cranberries have antioxidant properties that can prolong life when taken at any stage of life, suggests a study to be published in the February 2017 issue of Experimental Gerontology.
将于2017年2月发表在《实验老年学》(Experimental Gerontology)上的一篇文章指出,蔓越莓由于具有抗氧化性,无论在人生的哪个阶段食用,都有助于延年益寿。
Studies of antiaging compounds have shown that some are effective at certain stages of life but can be harmful in others, researchers said.
研究人员说,对抗衰老成分的研究表明,有些成分在人生的某些阶段有效,但在另一些阶段可能是有害的。
Experiments at the National Institute on Aging in Baltimore tested cranberry supplements on Drosophila, a type of fruit fly commonly used in biological research studies. Groups of 100 to 200 flies in separate vials were fed a high-sugar diet supplemented with 2% cranberry extract during the flies' three biological stages -- a health span, a transition span and a senescence span, according to the researchers. In humans, the stages correspond to young adulthood, middle and old age. Control flies didn't receive the extract.
位于巴尔的摩的美国国家老龄化研究所(National Institute on Aging)测试了蔓越莓补充剂对果蝇的效果,果蝇是生物学研究常用的实验材料。研究人员说,每组数量在100至200只的果蝇被装在不同的瓶子里,在它们的三个生物期(健康期、过渡期和衰老期)内被饲以高糖饮食并添加2%的蔓越莓提取物。这些时期在人类身上对应的是青年、中年和老年。对照组的果蝇没有接受蔓越莓提取物。
