在发展中国家,每5个人中就有一个长期营养不良者,总数已达到7.77亿。由于直接或间接的营养不良或过剩所导致的疾病,全世界每4秒钟就有一人死亡。我国每年因此造成的经济损失占GDP的3％～5％,约合2610亿至4350亿元。因营养、运动知识的匮乏,给国人健康方面带来的问题难以计数,并严重阻碍了我国人均寿命的增长。 In developing countries, one out of every five people has chronic malnutrition, bringing the total to 777 million. One in every four seconds in the world dies as a direct or indirect cause of malnutrition or excess. The annual economic losses caused by China account for 3% -5% of GDP, or about 261 billion to 435 billion yuan. Due to the lack of nutrition and exercise knowledge, the problems brought about by the health of the Chinese people are difficult to count and have seriously hindered the growth of the average life expectancy of our country.
