We used to have healthy food, until about 50 years ago, but now with all of the GMO and cross-breeding, about the only healthy food we can eat is meat, fish, and animal-derived products (such as eggs, cheese, etc.). The problem with today’s Frankenfoods is that they’re so new that our bodies haven’t had time to adapt to them...hence we get obesity and diabetes epidemics (and no, women didn’t go Planet Fitness 50+ years ago, nor did they need to).
This is a large part of the reason I grow my own and can or freeze as much of it as possible
Best diet is your Grandmother’s “diet” - (not a diet)
small amounts of meat (family of 8 would share one small chicken)
garden vegetables or stuff they canned
butter, cream, cheese, milk
breads
remember when an orange in your stocking was a big deal? (because oranges were out of season..)
