Humans don't need to chew their food at all. If there is enough moisture, you can swallow most foods whole in chunks. Chewing is part of the digestive process (especially for plant material) to increase the surface area of the food. Even carnivores with huge throats and few or no molars can be observed chewing certain foods.
