背景资料。对儿童和青少年的研究表明，零食的作用大大增加；然而，对年轻人零食行为的变化知之甚少。美国农业部从1977-1978年到1994-1996年进行了具有全国代表性的调查，调查了8,493名19-29岁人群的零食趋势。在1977-1978年和1994-1996年期间，零食流行率从77%上升到84%，零食对总能量摄入量的营养贡献从20%上升到23%，主要是因为每个零食场合消耗的能量增加了26%，每天吃零食的数量增加了14%。零食的日均热量密度(每克食物的卡路里)从1.05卡路里增加到1.32卡路里，高脂肪甜点对零食总卡路里的贡献下降(22%到14%)，但这一食物组仍然是最重要的能量来源。高脂肪咸味零食的能量贡献增加了一倍。含糖和酒精饮料仍然是重要的能量来源。结论，美国年轻人零食总能量和能量密度的大幅增加可能是肥胖流行的原因之一，(C)ZOOL美国健康基金会和学术出版社。
Background. Studies on children and adolescents suggest a large increase in the role of snacking; however, little is know about changes in the snacking behavior of young adults.Methods. USDA's nationally representative surveys from 1977-1978 to 1994-1996 are used to study snacking trends among 8,493 persons 19-29 years old.Results. Snacking prevalence increased from 77 to 84% between 1977-1978 and 1994-1996, The nutritional contribution of snacks to total daily energy intake went from 20 to 23%, primarily because energy consumed per snacking occasion increased by 26% and the number of snacks per day increased 14%. The mean daily caloric density (calorie per gram of food) of snacks increased from 1.05 to 1.32 calories, The energy contribution of high-fat desserts to the total calories from snacking decreased (22 to 14%), however, this food group remained the most important source of energy. The energy contribution of high-fat salty snacks doubled. Sweetened and alcoholic beverages remained important energy contributors.Conclusion, This large increase in total energy and energy density of snacks among young adults in the United States may be contributing to our obesity epidemic, (C) zool American Health Foundation and Academic Press.
