Mark 7:5-9 - Then the Pharisees and scribes asked him (Jesus), Why walk not thy disciples according to the tradition of the elders, but eat bread with unwashed hands? (6) He (Jesus) answered and said unto them, Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with [their] lips, but their heart is far from me. (7) Howbeit in vain do they worship me, teaching [for] doctrines the commandments of men. (8) For laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do. (9) And he (Jesus) said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition. See - Fountain of Living Waters vs. Cisterns and The Ten Commandments.
Mark 7:14-16 - And when he (Jesus) had called all the people [unto him], he said unto them, Hearken unto me every one [of you] and understand: (15) There is nothing from without a man that entering into him can defile him: but the things which come out of him, those are they that defile the man (person).
After Jesus was finished talking with the people and went into the house, his disciples asked him concerning the parable.
Mark 7:18-23- And he (Jesus) saith unto them, (the disciples), Are ye so without understanding also? Do ye not perceive, that whatsoever thing from without entereth into a man (person), [it] cannot defile him; (19) Because it entereth not into his heart, and goeth out into the draught, purging all meat? (20) And he (Jesus) said, That which cometh out of the man, that defileth the man. (21) For from within, out of the heart (soul or mind) of men (people) proceed evil thoughts, adulteries, fornication, murders, (22) Thefts, covetousness, wickedness, deceit, lasiviousness, an evil eye, blasphemy, pride, foolishness; (23) All these evil things come within, and defile the man (person).

In other words, it is not the food that you put into your mouth which destroys a person but that which comes out of your mouth---the words that you say, or what is in your mind--the bad thoughts you have, and bad deeds or things that you do---these are the things which destroy a person.
REMEMBER:- Your body is a temple.
I Cor.3:17 - If any man (person) defile the temple of God, him shall God destroy; for the temple of God is holy, which [temple] ye are. See - Temple(s) of God.
the temple (#2485) - metaphor - the spiritual temple consisting of the saints (holy) of all ages joined together by and in Christ
In this parable, Jesus is using a comparison between having unclean hands to receive the food into your body and which goes out from the body, in the form of speech, thoughts and the things which you do. The Pharisees thought that is was a sin not to wash your hands and/or your utensils, but what Jesus is trying to tell them---the bigger sin is that which you say, think and do.
However, Jesus would not tell us to do something/or not do something which would make ourselves unhealthy. So it really is important to wash your hands before you eat, to get rid of the germs which could make you (or your body), very sick.Fountain of Living Waters vs. Cisterns
