俱舍論記 10.193

10.193

「彼說且依至皆有四食」者，通。彼前四句及品類說，且依一向能資益者說名為食。以實而言，初益後損、或初損後益皆名為食，故不相違。熱鐵丸等初益後損，又孤地獄段食如人，故通五趣皆有四食。

"What they say is provisionally based on... all have the four nutriments" resolves the objection. Those previous four alternatives and the statement in the Prakaraṇa were provisionally spoken based on what is solely able to nourish and benefit being called nutriment. In truth, benefiting first and harming later, or harming first and benefiting later, are all called nutriment; hence there is no contradiction. Hot iron pellets and the like benefit first and harm later, and furthermore, solid nutriment in the solitary hells is like that of humans; therefore, universally, the five destinies all possess the four nutriments.
