Jamieson, Fausset & Brown, on Heb 13:9

“Be not led away with various and strange doctrines. For it is best that the heart be established with grace, not with meats; which have not profited those that walk in them.”

“about--rather, as oldest manuscripts read, "carried aside"; namely, compare Eph 4:14. divers--differing from the one faith in the one and the same Jesus Christ, as taught by them who had the rule over you (Heb 13:7). strange--foreign to the truth. doctrines--"teachings." established with grace; not with meats--not with observances of Jewish distinctions between clean and unclean meats, to which ascetic Judaizers added in Christian times the rejection of some meats, and the use of others: noticed also by Paul in Co1 8:8, Co1 8:13; Co1 6:13; Rom 14:17, an exact parallel to this verse: these are some of the "divers and strange doctrines" of the previous sentence. Christ's body offered once for all for us, is our true spiritual "meat" to "eat" (Heb 13:10), "the stay and the staff of bread" (Isa 3:1), the mean of all "grace." which have not profited--Greek, "in which they who walked were not profited"; namely, in respect to justification, perfect cleansing of the conscience, and sanctification. Compare on "walked," Act 21:21; namely, with superstitious scrupulosity, as though the worship of God in itself consisted in such legal observances.”
