美国宾夕法尼亚州立大学的一项研究显示,经常食用紫薯可能有助降低罹患结肠癌的风险。研究结果刊载于最新一期美国《营养生物化学杂志》月刊。研究人员以消化系统高度类似于人的猪作为实验对象,给第一群猪投喂高热量饮食,第二群猪投喂添加有或生或熟紫薯的高热量饮食,第三群猪正常饮食作为对照组。连续干预13周后,研究人员检查猪的结肠组织。结果显示,与对照组相比,高热量饮食组白细胞介素-6水平显著较高,意味着罹患结肠癌和
A study by Penn State University in the United States shows that regular consumption of purple sweet potato may help reduce the risk of colon cancer.
