> Food we ourselves decide to buy and eat.

Word 'decide' makes all the heavy lifting here. How come Japanese, Koreans and others make so much better decisions? Your decisions are a function of your environment and your education. Why don't Americans get good food environment and good food education?

>Nobody, absolutely nobody is blocking you or anybody else from buying tons of veggies and fruits, raw meat etc. Its cheap, cooking with it is trivial to reach cca average restaurant level of taste and one controls fully what final meal is composed of.

Are you not familiar with the concept of food deserts?

Healthy eating is available at restaurants too (Taco Bell being an amusing example - grilled chicken, beans, vegetables, and leafy greens) but people choose not to avail themselves of it. The straw man "Average American" is conditioned by companies to enjoy textureless, mild food loaded with fat, salt, and sugar so that they're never satiated and always craving more. Fiber and texture fly in the face of this so we end up with generations of people raised to eat chicky nuggies and bacon ranch dressing with a side of iceberg lettuce because onions are icky.
