Adolescents need good nutrition, both to grow to their full potential and to decrease their risk of obesity and chronic diseases in adolescence and later life. The Food Habits of Canadians study provides data on the important food sources of energy and nutrients in a sample of Canadian teenagers. One 24-hour recall was obtained for 178 teenagers living in households participating in a national survey of 1,543 adults. Foods were categorized into 51 groups, and ranked according to contribution of key nutrients, energy, and fibre. Top contributors to energy and other nutrients included foods of low nutrient density (cakes/cookies/pastries, carbonated beverages, sugars/jams/syrups, and salty snacks). A high intake of nutrient-poor foods, particularly high-sugar beverages, is a concern for this sample of Canadian teenagers.
青少年需要良好的营养，以便充分发挥生长潜力，并降低在青少年时期及以后患肥胖症和慢性病的风险。《加拿大人的饮食习惯》研究提供了有关加拿大青少年样本中能量和营养素重要食物来源的数据。对参与一项针对1543名成年人的全国性调查的家庭中居住的178名青少年进行了一次24小时饮食回顾。食物被分为51组，并根据关键营养素、能量和纤维的贡献进行排名。能量和其他营养素的主要贡献者包括低营养密度的食物（蛋糕/饼干/糕点、碳酸饮料、糖/果酱/糖浆和咸味小吃）。对于这个加拿大青少年样本来说，高摄入营养匮乏的食物，尤其是高糖饮料，令人担忧。
