Is it healthy to eat with hands??

Few days back i was thinking that how can it be health to eat with hands as our Prophet Muhammad(PBUH) always ate with his right hand's three fingers. So i went through several websites and asked different people and at last got satisfying answers. The most interesting reason i heard is:
When you eat with your fingers certain digestive enzymes are released by the fingers which aid in the digestion process.This also inhibits the deficiency of insulin, in addition to aiding the diabetics. Licking the fingers clean after eating insures that digestive enzymes are properly consumed and swallowed into the stomach which helps the eyes, the brain and the stomach. This is a great cure for various stomach ailments, brain diseases and heart problems.
Others are:
1.It promotes cleanliness. If you know that you will be eating with your hands you will be more likely to wash them before and after you eat.

2. Eating with your hands and using three fingers limits the amount of food you eat and it helps with being aware of the food you are eating, and it is helpful in preventing overeating.

3. By using your hands you can tell if the food is hot or not and prevent burning oneself, instead of just digging in with a fork. 

While there is a talk about eatig with forks and spoon you will see that lots of food get wasted while eating with hands you wipe off all the food and nothing get wasted.

I rather like to eat with hands and what do you prefer??!!
