Doing at least these to remain healthy!

       For our growth and getting energy, many parts of our digestive system having multitude of functional capacities are being kept ready and waiting to take in the food items provided through our mouth. Shouldn’t we do at least the duty of selecting good quality food items, making them clean and softer for easier digestion by them and check the foods' quality by tasting before swallowing? 

Those parts do not directly inform us about our taking-in of bad quality food. Instead, they intimate us indirectly by showing the discomfort or pain that develops - to alert and warn us not to take such bad food at the next instant. We must understand such communication, avoid bad quality food-intake and control ourselves in eating food items excessively to remain healthy.
