Sure they do. Let the modern experts tell us the proper diet we've been apparently doing wrong for tens if not hundreds of thousands of years. A little note: pretty sure all of those were not only rolled back but found that 'modern' diets are harmful: what a surprise.

I invite you to eat the bugs and stop bothering other people what to eat. Likewise, the "food pyramid" popularized from the 1990s has been factually wrong and even harmful to males especially, and only recent studies which have been analyzing the problem for 5-10+ years have been able to 'uncover' this.

People are kidding themselves if they don't understand that >most< of the 'eat the bugs' and 'stop animal suffering' aren't schemes and attempts (make no mistake, of the rich and the 'elite') to transition industries because we(as in the west) have been losing the industry apparatus, especially the food one. Does not mean there are no 'legitimate' movements or people who actually care, but most of them don't, they're just made to believe they do. Same goes for the green push, oh but here come the downvotes...
