I agree there's a lot of good nutrients in processed meat
However I wouldn't recommend eating hot dogs without reading the ingredients
I think there are 3 concerns
1) Chemical additives
2) Added sugar (which are sadly quite prevalent in meat)
3) Vitamin C (which is potentially denatured in pre-cooked meats and competes with added sugars for utilization in the body)
It's interesting because I'm from Italy and here nutritionists and doctors are gaslighting us into thinking that all our traditional cured meats that we've been eating for centuries now cause cancer and other diseases.
