As a society we’ve sold our souls to “science” a bit too much. The reality is that it’s HARD to study how good affects us.
Most research is survey based and guess at outcomes based on correlation.
At the end of the day, intuition may be more important. My body feels great when I have a steak. If I hadn’t grown up in a world that told me red meat is bad, I would have loved it a long time ago.
Heck, based on what everyone told me, I thought it was worse to eat steak than to eat skittles and starburst!
Maybe someday they’ll have a machine that tells us Exactly what we should eat for our health. Until then I’ll place my bets on steak.
