yes, meat has vitamin C. So does milk, especially sheep and goat but cow to a lesser extent.

put it this way, right now i mainly consume milk, and maybe a litre of beer, and a couple cups of coffee. The beer is taxing my immune system, as is the coffee, and the associated sleep disruptions. But in recent times I have had neither other for as long as a week and zero problems that i can connect to vitamin C deficiency, and that's just UHT cow milk. Fresh meat and raw milk are far more rich in it.

Carbs without an excess of antioxidants is toxic in other ways than respiratory health.
