Cook your food in water instead of over a fire during a survival situation for the most nutrition
When you need to cook something you have caught, hunted, or foraged, cooking it as a soup in a pot of boiling water is much more nutritionally efficient versus grilling it over an open flame.
By containing the food in the pot, all of the nutrients are infused into the surrounding water which can later be drank as broth. That’s why chicken noodle soup was a common “cure” to being sick, because back in the day the whole chicken was cooked into the soup and the bones, joints, and skin would be broken down into a very nutritionally dense broth. The can of Campbells chicken noodle soup from the store in 2022 does not provide the same benefit.
It’s also easier to make sure that the food is cooked thoroughly if it has been boiling in a pot of water for some time. You can’t burn and char it in water but that can happen over an open flame.
A grilled piece of meat will always taste so much better, but in a survival situation you want the most nutrition as possible in soup form.
