食物的品种少、进食过多、脂肪和糖摄入过量是美国儿童中最普遍存在的营养问题。一些学者认为改变学生膳食应作为培养良好饮食习惯和针对慢性病的预防(而不是治疗)的一种办法。美国自1946年开始实施“国家学校午餐计划”以来,通过提供富有营养、价格合理的午餐,保证了儿童的健康。1977年又作了修改,促进了把午餐室活动与教室营养教育相结合,进一步改善了儿童营养摄入和饮食习惯。这种把营养教育与学校午餐计划相结合的创新计划称为“学校营养活动计划”(SNAP)。它参照《美国人饮食指南》的规定强调食用低脂肪、低胆固醇、低糖和低盐的食物。据此制订
Fewer species of food, too much food, excessive intake of fat and sugar are the most common nutritional problems among American children. Some scholars believe that changing student meals should be a way to develop good eating habits and prevent (but not cure) chronic diseases. Since the implementation of the National School Lunch Program in 1946, the United States has ensured the health of children through the provision of nutritious and affordable lunches. Revisions were made in 1977 to promote the combination of lunchroom activities with classroom nutrition education to further improve children’s nutritional intake and eating habits. This innovative program that combines nutrition education with a school lunch program is called the School Nutrition Program (SNAP). It refers to the American Dietary Guidelines emphasizing the consumption of low-fat, low-cholesterol, low-sugar and low-salt foods. Formulated accordingly
