ORIGINAL: youngitalianbabe Which problems are you referring to? Because the last time I checked - the 'problems' were justified..
In answer to your second question, perhaps the word 'efficiently' was a little innaccurate, but I should think more easily digested. Since chewing does not completely puree food, further breaking down processes are used in the stomach. By eliminating the need for these processes it could be concluded that the body has to do less in order to make the nutrients ready for absorbtion. However, since these processes, and chewing, require calories to be expended, and liquidised meals do not require such calorific usage, it can be said that digestion of a liquidised meal is more efficient (in the strict sense of the word. Sorry for sounding so ****y.
