Most children in urban areas, for instance, are accustomed to eating food that is more delicately prepared. Their teeth aren't as strong and they don't like to spend a lot of time chewing their food. Schools could serve coarse rice and foods high in fiber and calcium, but what if children turn their noses up at their lunches?
以都會區的孩子為例，多半習慣吃精緻食品，牙齒不夠強壯、不愛咀嚼，學校供應的糙米飯、高纖高鈣食物，孩子覺得不好吃怎麼辦？
