What I am pretty disgusted about is what this society has done to food. That much of the grocery store is packaged stuff that isn't food at all, the same for restaurants. It's literally substances that are chemically engineered to appeal to you, engineered precisely to push your buttons to simulate nutrition. They might have about the nutrition of the box they come in, but they are engineered to taste like the real thing (one drop of natural flavoring will do it). That much of conventionally produced food especially animal products is hardly food at all (chickens fed arsenic, chickens that never see the sun, meat treated with chemicals to make it turn red after it has browned, cows doped up on hormones and antibiotics to fatten quicker, yea that's not food).
But if one agrees people should eat real food like people have for time immemorial (yea even after the dawn of agriculture!) then that will drive one to more organic and naturally raised food, and that I believe in. But then there's still a lot of sub-debates about what real food among all the foods out there to eat: mostly plants? should one eat dairy? wheat? legumes? butter? only olive oil? lots of red meat? and frankly I don't think this part is very clear cut.
I think on the one hand there's people spinning tales of what strict diet they hope will keep them perfectly healthy in thier truly old age (90s and so on), and I'm not sure they understand how rare that is, frankly what really old age usually is. And on the other hand there's food companies whose absolute garbage passed off as food contributes to making people not just not model thin (who cares) but more and more extremely obese. So that these people take dangerous diet pills to try to lose weight totally oblivious to the fact that they have been completely played by a corrupt food system (diet pills are still related to amphetamines, half a century, nothing changes). Diet pills that raise blood pressure and cause irregular heart beats and may stop your heart and mcdonalds and packaged meals, in what universe does that make sense (yea talking about someone I worry about).
As for fun I ocassionally have the desire to follow the food restrictions of various religions for a period of time: orthodox lent, ramadan, etc. which is no doubt quite inappropriate as I'm not of those religious traditions but then if that's the case why should anyone care how I eat?
