《人间食粮》是纪德游历北非和意大利之后，以抒情方式，糅合传统的短诗、颂歌、旋曲等形式写成的一连串富有诗意的断想。他以炽热的灵魂感应生命的花果，并将这赤诚之爱整个地化作颂歌、凝成诗语。此书可谓纪德本人最激越的精神独白，被奉为"不安的一代人的《圣经》"。(Fruits of the Earth is a series of poetic imagery written in a lyrical manner with a blend of traditional short poems, carols, revolutions, etc. after Gide travels to North Africa and Italy. He senses the breath of life with his blazing soul, and turns this sincere love into carols and poems. This book can be described as the most radical mental monologue of Gide himself, regarded as "Bible of unease generation".)
