Why does the government try to intervene on what we want to eat?

They're slowly trying to take away our every right. I am a healthy eater, because I choose to be. If someone else wants to fill up on burgers and fries, that's their choice, and their right. I think that every restaurant should post their nutritional information so that people who want to eat healthier can make better choices, and those who don't care can ignore it and eat what they want anyway. I don't think the gov't should be able to dictate what the restaurants can and cannot put into their foods. It's our choice whether or not we want to consume them, not the governments!!
