若依正法念經說。修羅衣食自然。冠纓衣服純以七寶。鮮潔同天。所餐飲食隨念而生。悉皆百味與天同等。如大論說。彼之衣食雖復勝人。其若喫時。是則不如人也。謂彼凡所食時。末後一口要變作青泥。亦如龍王雖食百味。末後一口要當變作蝦蟇。是故經說不如人也。

According to what is taught in the Saddharmasmṛtyupasthāna-sūtra: Asuras' clothing and food are spontaneous; their caps, ribbons, and robes are made purely of the seven precious substances, fresh and pure like those of the devas. The food and drink they consume appear according to their thoughts, all possessing the hundred flavors and identical with those of the devas. As the Mahāprajñāpāramitā-śāstra states: Although their clothing and food surpass those of humans, when they eat, it is not as good as humans'. That is to say, whenever they eat, the very last mouthful must turn into blue mud. Just as when a nāga king, although eating the hundred flavors, finds that the very last mouthful must turn into a toad, therefore the sūtras state that it is not as good as humans'.
