Always found this passage interesting
St. Paul is referring to sects which ban marriage and certain foods outright. The Catholic Church does neither - no Catholic is compelled to be celibate and no Catholic is compelled to avoid any foods.
St. Paul himself was a celibate and recommended it to others, so celibacy is not wrong or unScriptural - only compulsive celibacy is.
Likewise abstaining from certain meats - which St. Paul admits to be permissible and which St. Peter and St. James recommended - is likewise an acceptable disciplinary measure.
No Catholic is forbidden marriage or food of any kind, so as interesting as this Scriptural passage is, it simply does not apply to the Catholic Church. It applies to the groups (most likely Gnostics and Ebionites) whom St. Paul is warning his fellow Catholics against.
