澳洲一份新近研究指出，兒童與青少年，長期食入大量的垃圾食物，不僅會變胖，就連認知力 (cognitive performance) 與智力等等，也會一同衰退。此研究來自澳洲 UWA and the Telethon Kids Institute，觀察六百多位青少年，所得出的結果。
青少年時期為大腦發育關鍵 垃圾食物養分不足
研究人員首先在青少年都還在 14 歲時，請他們填寫一份問卷，以此來統計這些青少年的飲食習慣，分為健康飲食與「西化飲食」，直到三年後，再進一步進行認知評估。
It was found that the participants with a western dietary pattern, characterized by high intakes of takeaway food, red and processed meat, soft drink, fried and refined food, scored lower in cognitive tasks, particularly those involving reaction time/psychomotor function, visual attention, learning and memory.
評估發現，長期食入垃圾食物的青少年，他們的認知、智商、記憶力、學習力等等，都較當初填寫健康飲食的青少年，分數來的較低，研究人員認為，青少年時期，為人類大腦的發育關鍵時期，而健康的飲食，能夠幫助孩童攝取更多的養分，有助於大腦的發育。
