I went to the hospital later that year with a kidney stone, and was told: Stop eating the spinach and cut back on nuts, these foods are way too high in oxalates! Other than that I was healthy as a horse, with a resting pulse of 40 bpm and having lost 100 lbs.
I'm an anecdote, but many people look and feel OK and eat tons of refined sugar. That's part of the reason it's still around. We like it and show no ill effects.
Was processed food in supermarkets a hundred years ago? Humans don't need it. Of course food is safer than 100 years ago, but also processed food has pulled apart healthy and unprocessed food from our diets.
Nestle, Coca-Cola, Unilever, they are in universities, associations, etc... we see plenty of cases here in Spain. They do courses for professionals... and they are the brands with the best public perception. And we say advertising doesn't work?
I generally agree with your point above, but you could have said it much clearer.
Avoid the slang like 'dunno' + 'coz', commas have a space after them and split your posts into paragraphs for readability. Also work on properly capitalising, it's a mistake you're constantly making in your previous posts.
