其一、美國人喜歡一日多餐，每餐適量；而中國人傳統習慣一日三餐，每餐食量都較大，且現已開始有不食早餐的風氣。無疑少食多餐會比一日三餐、二餐科學，特別是不食早餐更易患膽石癥。其二、許多中國人習慣每日購買新鮮食品烹飪；美國人往往一次性購買一周的食品貯存在冰箱里，每日食用冷凍食品，且食用的罐頭和腌制品分別為中國人的八倍和六倍，要知道它們含較多的防腐劑和色素等化學品，均對身體不利，這值得生活日趨簡單化的都市白領一族注意的。 其三、中國許多家庭逢年過節時菜肴特別多，應酬也特別多。而美國人宴客或過節，從不鋪張，連總統宴請外國元首也是五菜一羹，更不勸酒。 其四、中國人烹調時喜歡用植物油，美國人則喜歡用含膽固醇較高的動物油。植物油為不飽和脂肪酸，不含膽固醇，因此美國人的心血管疾病發病率特別高。 Diet Culture difference between China and America.（中美飲食文化的差異）這篇可以參考：）~ The main difference between Chinese and America eating habits is that unlike, where everyone has their own plate of food, in China the dishes are placed on the table and everybody shares. If you are being treated by a Chinese host, be prepared for a ton of food. Chinese are very proud of their culture of food and will do their best to give you a taste of many different types of cousin. Among friends, they will just order enough for the people there. If they are taking somebody out for dinner and the relationship is polite to semi-polite, then they will usually order one more dish than the number of guests (e.g. four people, five dishes). If it is a business dinner or a very formal occasion, there is likely to be a huge amount of food that will be impossible to finish. A typical meal starts with some cold dishes, like boiled peanuts and smashed cucumber with garlic. These are followed by the main courses, hot meat and vegetable dishes. Finally soup is brought out, which is followed by the starchy staple food, which is usually rice or noodles or sometimes dumplings. Many Chinese eat rice (or noodles or whatever) last, but if you like to have your rice together with other dishes, you should say so early on. 參考資料：
