Whether gluttony is a capital vice?

Objections

Objection 1 : It would seem that gluttony is not a capital vice. For capital vices denote those whence, under the aspect of final cause, other vices originate. Now food, which is the matter of gluttony, has not the aspect of end, since it is sought, not for its own sake, but for the body's nourishment. Therefore gluttony is not a capital vice.
Objection 2 : Further, a capital vice would seem to have a certain pre-eminence in sinfulness. But this does not apply to gluttony, which, in respect of its genus, is apparently the least of sins, seeing that it is most akin to what is in respect of its genus, is apparently the least gluttony is not a capital vice.
Objection 3 : Further, sin results from a man forsaking the food of virtue on account of something useful to the present life, or pleasing to the senses. Now as regards goods having the aspect of utility, there is but one capital vice, namely covetousness. Therefore, seemingly, there would be but one capital vice in respect of pleasures: and this is lust, which is a greater vice than gluttony, and is about greater pleasures. Therefore gluttony is not a capital vice.
