I don't say everything is toxic and is going to kill them. I talk about a specific list of things that just happen to be in tons of our "normal" foods that are toxic and cause significant health problems, and to get food without them. 

We are the sickest generation ever in the history of this country and we are also one of the unhealthiest populations in the western world. If you hand wave this away with "people just need to exercise but our food is fine" then there isn't much of a conversation to be had because, imo, you aren't even looking for an explanation. You are just trying to find an excuse for what's "normal" by apparently (as you seem to have just done) claiming that "it's normal" and thus not a problem or "too hard."

Ironically seed oils weren't at all normal, and were only used as engine oil back in the "60 years ago" when most of the other things weren't a problem either, and far more of what we consumed were basic real foods and high in animal fats... interesting 🤔
