Sforno on Deuteronomy 12:25/ספורנו על דברים י״ב:כ״ה

1'לא תאכלנו....כי.תעשה הישר בעיני ה, when you refrain from eating it this shall not be because you despise it, i.e. it repels you; you must not eat it in order to thereby do what is right in the eyes of the Lord. Our sages in Torat Kohanim on Kedoshim 9,10 phrase it thus: “one must not say: ‘I am revolted by pig’s meat,’ but one should say: ‘I am perfectly capable of enjoying pig’s meat; the only reason I do not is in order to comply with G’d’s prohibition of it.’”
