Hi anon
Typically cooking food makes it far easier to digest but will lose some nutritional value.
Chimps have to spend much more energy in their stomachs digesting food than we do, but get slightly more energy out of it.
Your body knows how much something should be cooked. When it looks juicy and right then ts good too eat. If it looks too raw or too cooked, then it's not ideal. Your brain knows a lot that you dont know.
