There's tons of healthy food options available to consumers these days, even in regular supermarkets. They all have "organic" food aisles now. Some Americans have become more conscious of this and have adjusted their diets. (Of course, there's also some companies trying to profit off this unfairly, like advertising "gluten free" on foods that would never contain gluten anyway, and also pushing gluten-free foods as "healthier" when there's really no evidence for that, they're healthier of course for people with a gluten allergy or sensitivity but that doesn't extend to everyone.) In a democratic society, it's the people's responsibility to be educated about issues, so they can vote accordingly. Most Americans are making conscious choices to eat bad foods, not exercise, live in suburbs with car-dependent lifestyles, etc. They could move to inner cities and/or push locally for more density and anti-car measures, but they don't, outside of a few select places. Instead, a large chunk of American society "educates" itself about conspiracy theories and the "importance" of guns and religion, and votes accordingly, and what you get is the society you see now.
