When you read Paul's account of his meeting with the Jerusalem leadership, you get a very different picture to that which is given in Acts.
Paul, who was based at Antioch, had little regard for those Judaising persons. He reported that all he was told at the meeting was to care for the poor. Further, his attitude towards food was completely at odds to the position taken in the report in Acts.
How can Paul's report be so totally different to the Acts account? It's very simple really. The book Acts of the Apostles (there was a number of writings called Acts) was the creation of a writer who lived some 40 years after Paul died, and is generally recognised as religious fiction. Its accounts of Paul's travels, for example, do not accord with Paul's record. Several supposedly historical events are incorrect.
In Acts, the writer told stories of how he thought things should have been, rather than what actually happened.
There was a deep division between the Pauline party based at Antioch and the Petrine party based at Jerusalem (see "Crisis of Conscience" -- I cannot remember the page number). (The reference from Galatians by Fernando provides a great insight into that sharp division.) So read Acts keeping in mind the internal politics at the time and the points each group was trying to make.
