Because most people don't know very much about nutrition, Li Te-wei provides these two simple principles: First, eat grains and beans together, such as red beans and rice, "eight-treasures" congee, and lentil and rice porridge; and second, the more variety in the colors of food eaten, the better.
有鑑於一般人對於食物的營養成分並不太瞭解，李德威提供簡單的兩大參考原則，第一，穀類和豆類混合吃，如：紅豆飯、八寶粥、綠豆稀飯等等；第二，攝取的食物顏色種類越多越好。
