我国卫生部等部门2004年10月发布的“中国居民营养与健康调查”表明,当前我国居民膳食方面存在的主要问题是,不能科学合理地把握摄入食物的结构和数量。除了部分维生素和矿物质摄入仍然不足外,在城市乃至一些农村地区,已经普遍出现某些营养素摄入过剩的局面。专家认为,不合理的膳食结构已经成为各种慢性病的罪魁祸首。 China’s Ministry of Health and other departments released in October 2004 “Chinese residents nutrition and health survey ” shows that the current diet of our residents there is the main problem is that science can not be reasonable to grasp the structure and quantity of food intake. In addition to some inadequate intake of vitamins and minerals, certain nutrients have been reported to be in excess in urban and even rural areas. Experts believe that unreasonable diet has become the culprit of a variety of chronic diseases.
