McD's is very low quality nutrition. There is more to nutrition than macronutrients. There are wayyyy better things you can put into your body with better vitamin and mineral absorption and much better for gut health.

Yes, but nobody likes people who tell them sanctimoniously that their dietary/smoking/drinking/non-exercising/chair-sitting habits are wrong.

"Fries" have basically zero nutritional quality, they're potato deep fried in the cheapest oil that the human body is capable of digesting. There is nothing even remotely nutritious about them. You're able to get usable calories from them. They'll prevent you from starving, but that's about the extent of it. I find it funny that you're accusing me of "elitist signalling". Looking after your health isn't "elitist", but how well you look after your health is definitely a factor that will go a long way to influencing your socio-economic status.
