其一、美国人喜欢一日多餐，每餐适量；而中国人传统习惯一日三餐，每餐食量都较大，且现已开始有不食早餐的风气。无疑少食多餐会比一日三餐、二餐科学，特别是不食早餐更易患胆石症。其二、许多中国人习惯每日购买新鲜食品烹饪；美国人往往一次性购买一周的食品贮存在冰箱里，每日食用冷冻食品，且食用的罐头和腌制品分别为中国人的八倍和六倍，要知道它们含较多的防腐剂和色素等化学品，均对身体不利，这值得生活日趋简单化的都市白领一族注意的。
其三、中国许多家庭逢年过节时菜肴特别多，应酬也特别多。而美国人宴客或过节，从不铺张，连总统宴请外国元首也是五菜一羹，更不劝酒。
其四、中国人烹调时喜欢用植物油，美国人则喜欢用含胆固醇较高的动物油。植物油为不饱和脂肪酸，不含胆固醇，因此美国人的心血管疾病发病率特别高。
Diet Culture difference between China and America.（中美饮食文化的差异）这篇可以参考：）~ 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 ppared 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.
