和垃圾食物划清界线。
They’re not really foods, anyway. Chips, dips, crunchies, munchies — sounds like something you throw to the animals at the zoo. Junk food is low in nutrition, high in calories and almost guaranteed to pack on the pounds.
反正它们也称不上是真正的食物。洋芋片、沾酱、脆片、脆饼――听起来好象那些你丢给动物园里的动物吃的东西。垃圾食物营养价值低,卡路里高,而且保证几乎全是大包装的。
