Basically anything that super processed or refined like sugars, carbs, and especially cooking oils. I feel so much better after cutting that stuff out. I already do low carb due to family history of diabetes but after I read up on how messed up the cooking oil industry is, and how these cooking oils are so extremely refined, I cut those out too. Made a world of difference. I primarily only use cold pressed oil now like coconut, olive, palm, and avacado. When I have carbs it’s primarily from fresh vegetables and occasionally fruits. Basically most of what I eat are things that haven’t undergone a lot of processing and I make a lot of stuff myself. Like the biggest difference between the diets of old humans vs modern, when you look at the global history of diets, is how precessed the food was. Some cultures ate tons of carbs through farming tubers, some eat almost entirely meat and animal products, and tons of cultures that eat a huge mix of everything in-between, and most all of them were healthier than we are now (from a diet health standpoint).

The one big difference that sticks out is we eat a bunch of shit now that we can’t normally get without a ton of crazy processing. Like shit we mine out of a certain rock hundreds of feet below the earth, or something we get through multiple extractions from a plants that then fermented into a sugar substitute after it’s then chlorinated. Or shit like cottonseed and rapeseed oil which comes out of an otherwise inedible seed they have to heat at high temps repeatedly while pressing out the oil, then mix and filter with petroleum solvents to create an oil that doesn’t smell like rancid dogshit. It’s all this processing and crazy shit we do to foods now.
