Nutrition. I spent years reading about nutrition to the point of being afraid to eat basically anything, I went to a “nutritionist” school with a strong anti animal product bent.
I don’t want to hear your nutrition “facts.” If it works for you, good for you! If you want my advice about what works for me, I’ll freely give it when asked. But literally every research based bit of nutrition advice can be contradicted with another bit of research based nutrition advice and most people are working with a model of nutrition science from about 1995.
I swear if I have to listen to one more emotional to the point of tears monologue about the perils of soy/dairy/meat/gluten/carbs/cholesterol/saturated fat/vegetables/“modern fruits”/grains/unfermented foods/bioaccumulated whatevers/etc WHILE I’M TRYING TO EAT, I may take advantage of my pointy food weapons.
Eat what makes you feel vibrant and leave everyone else alone.
