Bad vs. Good Foods

Metaverseguy: I wish people would make up their mind on what foods are unhealthy. First, there's a book that tells you to eat lots of red meat and protein. Author dies.

Then, eggs are good one year and bad the next. Is there like a calendar that lets us know when foods are good for us or do we just guess?

Because everyone agrees unanimously vegetables, fruit, and fiber is good and that alcohol, tobacco, and fatty snacks aren't.
