Sorry it appears that way in false world... but for those seekers not trapped in false world...
The point is that the Lord’s command frees Peter from any scruples about going to a Gentile home and eating whatever might be set before him. It would be a short step from recognizing that Gentile food was clean to realizing that Gentiles themselves were ‘clean’ also.
The Savior had already spoken declaring all foods clean.
" ... there is nothing outside the man which can defile him if it goes into him; but the things which proceed out of the man are what defile the man.... "And He said to them, “Are you so lacking in understanding also? Do you not understand that whatever goes into the man from outside cannot defile him, because it does not go into his heart, but into his stomach, and is eliminated?” (Thus He declared all foods clean.)"
And The Apostle Paul also confirmed this.
"For Christ is the end of the law for righteousness to everyone who believes... "I know and am convinced in the Lord Jesus that nothing is unclean in itself; but to him who thinks anything to be unclean, to him it is unclean."
And again from the Apostle Paul stating all foods are good and can be eaten.
"But the Spirit explicitly says that in later times some will fall away from the faith, paying attention to deceitful spirits and doctrines of demons, by means of the hypocrisy of liars seared in their own conscience as with a branding iron, men who forbid marriage and advocate abstaining from foods which God has created to be gratefully shared in by those who believe and know the truth. For everything created by God is good, and nothing is to be rejected if it is received with gratitude; for it is sanctified by means of the word of God and prayer." 
Eat Hearty Believers!
” ... there is nothing outside the man which can defile him if it goes into him; but the things which proceed out of the man are what defile the man.... “And He said to them, “Are you so lacking in understanding also? Do you not understand that whatever goes into the man from outside cannot defile him, because it does not go into his heart, but into his stomach, and is eliminated?” (Thus He declared all foods clean.)”
3. Jesus statement in Mark 7:19b katharizon panta ta bromata
(“cleansing all the food”) can be understood as an IRONY. Christ is
contrasting the tradition of the elders with the biblical law and
demonstrates the difference between spiritual and physical defilement.
Many scholars recognize today that Jesus and the apostles were not
against the dietary laws, but against their misuse. Since their original intent
was distorted He had to restore their true meaning. Jesus’ teaching does not
diminish the validity of the dietary regulations. Danger to the purity of the
mind and the heart is more important than what goes into the stomach.
Modern translators often fail to reflect that Jesus is referring in Mark
7 to food that is koinos—desecrated/polluted by association—and not to
food that is akathartos (“unclean”), because the word “unclean” does not
appear in this pericope. The same can be said about Matt 15:11, 17–20.
It has nothing to do with Levitical laws. And very importantly, (thus he declared all foods clean) was added by the translators. It is NOT in the KJV bible. (Oh, you don’t use the KJV bible?)
Mark 7 has absolutely nothing to do with Levitical food laws. It has everything to do with TRADITIONS OF MEN. The Irony is that you can’t see it.
1Then came together unto him the Pharisees, and certain of the scribes, which came from Jerusalem.
2And when they saw some of his disciples eat bread with defiled, that is to say, with unwashen, hands, they found fault.
3For the Pharisees, and all the Jews, except they wash their hands oft, eat not, holding the tradition of the elders.
4And when they come from the market, except they wash, they eat not. And many other things there be, which they have received to hold, as the washing of cups, and pots, brasen vessels, and of tables.
5Then the Pharisees and scribes asked him, Why walk not thy disciples according to the tradition of the elders, but eat bread with unwashen hands?
AGAIN, you do not know how to rightly divide the word of God.
4. When I ask my audience what kind of animals were in the sheet Peter saw in his vision according to Acts 10, the typical answer is a “variety of different kinds of unclean animals.” However, this answer is wrong, because the biblical text shows that in the sheet were unclean as well as clean animals. This observation leads to a crucial question: What was then the problemfor Peter? He could pick up the clean animal and “kill and eat,” but he refused. Bruce is right when he asserts that Peter “was scandalized by the unholy mixture of clean animals with unclean; this is particularly important when we recall the practical way in which he had immediately to apply the lesson of the vision.” Thus, the real problem for Peter was association of clean animals with the unclean animals otherwise he could pick up a cow, sheep, or goat from the shown creatures and prepare it for food. Peter felt he could not eat anything, because even the clean animals became unclean by association with the unclean animals, a concept which is not supported by the Hebrew Scriptures (a living unclean animal is not a source for uncleanness!), but only by rabbinic tradition.
God asked Peter to stop calling the clean animals koinos, i.e., defiled by association with the unclean animals. This meant that he (a Jew) had to stop considering himself unclean by associating with Gentiles. This goes along with a different concept which was also developed during the intertestamental period—the symbolic interpretation of animals into two categories: clean animals represented the Jews and unclean animals symbolized the Gentiles/pagans. This had tremendous implications for their social life, because they needed to be constantly watching not to become defiled by association with unclean pagans. If a Jew was in close contact with a pagan he thus became polluted. In the time of Jesus and the apostles, there were huge social barriers between Jews and Gentiles. They could not eat together or visit each other in their homes for a variety of reasons (food could have been offered to idols; connected with unclean animals; prejudices). Through the vision, Peter was taught that the social barriers between Jews and Gentiles had fallen down (he was now free to socialize with them and visit the house of a pagan Cornelius), and not that a biblical distinction between clean and unclean animals was no longer valid (see Acts 10:28; 11:12).
