美国研究人员日前通过改变胡萝卜的某些基因,研制出一种富含钙的转基因胡萝卜,常食用这种转基因胡萝卜可起到“强筋健骨”的效果。美国休斯敦贝勒医学院的研究人员以年龄在21￣29岁的15名男性和15名女性为研究对象,让他们在不同的时段分别食用普通的胡萝卜,以及研究人员培育 A few days ago, American researchers developed a kind of genetically modified carrot rich in calcium by changing some genes of carrot. The carrot can often play the role of strong gluten bone. Researchers at the Baylor College of Medicine in Houston, USA, studied 15 men and 15 women aged 21 to 29 and asked them to eat ordinary carrots at different times and to nurture researchers
