Question

I want to know what are the effects of not using your teeth togrind foods but preparing it before eating with blending andgrinding them into a liquid.

Here I am not talking about any weight loss or fitness industryprepared drinks. I mean the ordinary raw and cooked foods likemeat, vegetables, cereals, and fruits that one would normally eatin classic meals.

Would this decrease of work done by teeth and digestion systemhave positive or negative health effects?
