其實不難寫，有幾個點給你參考：
1. 歷史，中國歷史5千年，美國不過二三百年，歷史的長短造成巨大的差異
2. 地理，中國和美國地理相隔較遠，物種差異較大，對飲食產生直接的影響
3. 族群，中國以漢族為主，美國則是移民國家，飲食豐富程度各有千秋
4. 關系，中美飲食互相影響，美國有中國餐館，中國有美國快餐
5. 融合，全球化時代，飲食不再受地域限制，可以互相學習，交融

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 cuisine. 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.
