Response to "Our national eating disorder"

According to Michael Pollan, the author of "Our national eating disorder", the eating habits of Americans have changed a lot, and lots of national food are fading away from Americans' tables. The author states two main reasons for this situation. Firstly, the author thinks that the government made great impact on national eating disorder. The author also lists a example to support his opinion, which is that "A scientific study, a new government guideline, a lone crackpot with a medical degree can alter this nation's diet overnight"(1). According to my experience, I agree with  the author. Because people sometimes believe the official nutrition report or the suggestions of professionals and are willing to choose food depending on these. Another example the author mentions is that "Once the federal nutritional guidelines tried to asked people who preferred beef not to eat red meat any more"(1). From this example, I noticed one of the reason why the government nutritional guidelines can alter American national diet habit more or less is that the food the government suggested are mostly substitutes, so most Americans do not need to do complete changes. Secondly, the author claims that as a immigration country, American national eating habit is easily influenced and reshaped by its various immigrants' food cultures and diet habits. 
In terms of myself, I never constrain myself from choosing different types or flavors of food. I am willing to try various new things, get to know different people and get involve in fresh surroundings all the time. However, it still hard to change my stubborn national diet habit. Although I have tried plenty of delicious American style food, the food making me excited the most are still authentically  traditional flavored Chinese dishes.
