In Ayurveda it is suggested that such and such food items are to be chewed so many times - 32 times or 16 times etc. All the medical systems insist proper chewing before taking in . No system allow swallowing unless it is liquefied or powdered.

True that chewing food before swallowing is good for digestion. Because it takes more saliva with it to the intestine. There is a video in Youtube, "Drink your food and chew your water" by Actor Madhavan. It is in English only. So, people whoever watches it, will get to know how to intake the food and why it is important to have food in such a way.
There are some animals which eat fast and later on they bring them back to the mouth and chew them sufficiently and then again swallow. It's called regurgitating. This facility is given to some animals but not to human beings.
That is why many times we see these cows chewing always something in the mouth. The food swallowed will be sent back to the mouth by the digestive system slowly in portions like a controlled vomiting. This will be chewed by the cow further and then swallow the food.
If not chewed properly then the same would lead to indigestion or stomach pain. Adding in to the author's query, the cow & buffalo & may be the camel which can often be seen with continuous chewing.
