Eat real food: Steak & eggs.
Saturated (animal) fats are best.
Plants are poverty food & they're mostly trying to kill you. We aren't able to make much use of nutrients wrapped in cellulose, & plants protect themselves by producing toxins that cause inflammation & leech things out of our system.
Grains are not fit for human consumption, we don't eat grass & grains are grass seeds which the plants most want to protect with lectins, oxalates, saponins, etc. And to make matters worse the overwhelming majority now are soaked in herbicides & pesticides. Even before the spraying became a problem farmers were using grains to fatten all kinds of livestock & to produce foie gras. And yet people still wonder why kids stuffing their faces with cereal & corn syrup are getting fatty liver disease.
Nuts are also seeds which are loaded with oxalates & other troublesome things. Drinking nut milks, eating nut butter, & consuming wildly unnatural amounts of nut products will cause inflammation, can cause skin issues, kidney stones, etc.
Seed & Veg oils are industrial lubricants made from crop waste & they were rebranded as edible when companies were trying to cut costs during the inflation of the 70s
Conclusion:
Animal meat should be the primary focus of a healthy diet. Vegetables are completely unnecessary, but won't kill you if they have a minor role in your diet.
