Not everybody around the world lives in such abundance like here in America. In poor countries, your lucky to eat anything. You don’t get to be picky. The point is, we should be grateful for what we have and not overthink nutrition.
Don’t be too picky when selecting food and don’t spend too much. No matter how advanced the human race gets, vegetables will always be man’s main food stuff.
There is an observable trend in the West that people are trying to be healthier. But remember, at the end of the day, its all about calories in and calories out.
Also, people in the USA tend to overdo animal foods like meat and milk. Previous generations didn’t gorge themselves day in and day out. They also did natural farming and gardening before the invention of the term, ‘organic’.
There is no reason to eat ‘health food’ because it’s just too complicated. Eat less often and less in between meals, and your body will recuperate. That’s the reality of the situation.
