Law? - Acts 16:28, 29

"For it seemed good to the Holy Spirit and us to lay no greater burden on you than these requirements: You must abstain from eating food offered to idols, from consuming blood or eating the meat of starngled animals, and from sexual immorality. If you do this, you will do well. Farewell. Acts 16:28, 29

OK, I am confused. How are the requirements to follow part of Mose's Law different from requiring circumcision? I thought God told Peter, "If God says something is acceptable, don't say it isn't." Isn't this just like what the Judaizers were doing? Adding law to Christ's work on the cross as a requirement for salvation? I thought the message was, "CHRIST PLUS NOTHING"? All the apostles seemed to be in agreement, so I must be missing something (maybe it wasn't a salvation issue?). Maybe someone more learned than I will comment?

Jesus, make your message crystal clear, free from confusion.
