I don't see red meat as an issue, rather processed red meat. Humans evolved around eating meat and that is what the body really needs and is really designed for. Along with certain fats. Red meat is demonized out of ignorance and a misconception that all fats are bad.
Things like high fructose corn syrup, dimethylpolysiloxane, beta hydroxy acid, azodicarbonamide, ect are on orders of magnitude more toxic and carcinogenic even though destination science is trying to say otherwise. Certain pesticide and insecticide are much the same: not very healthy as some always lingers behind.
Hybridization and genetic engineering has taken nutrients out of fruits and vegetables for equalized ripening, uniform yields, plant tolerance, ect. Great for the farmer, not great for the human. If you ever grow heirloom fruits or vegetables they are nothing like the picture perfect all identical looking produce you buy at the store.
Good frying is healthy when done in the right oil at the right temperature. As the food is heated in oil, it boils water out pushing oil away preventing ingress into the food. What residual coating is left behind on the outside is very small, much smaller than what you find in salad dressing, breads, baked goods, cookies, ect which are literally made with cups of vegetable oil.
Only when things are over cooked in oil leaving no internal water within it or the oil is broken down does the food start absorbing said oil. Speaking of broken down oil- broken down oil causes food to be soggy and greasy feeling. Restaurants pushing oil well beyond its useful life began seeing this. So in addition to adding chemicals to stabilize the oil they began using hydrogenated oil. Hydrogenated oils solidify at a lower temperature. So if the food was absorbing oil making it feel greasy before hand, hydrogenated oils solidified after-hand creating the perception the food was not oil logged even though it was.
It was this in part which gave fried foods a bad name- Restaurants cooking in rancid oil and sadly to this day even with all the additives and grotesque chemical engineering way to many restaurants are still pushing oil well past its usual cooking life.
Actually the healthiest substance to fry in IMO is beef tallow. But again because of ignorance of what causes healthy problems beef tallow was switched over to vegetable oils and worse. Much like questionable butter being replaced with what I feel are much worse margarine.
