有些果食主義者只吃會從植物上自然掉落的食物，也就是不用傷害植物就能收割的食物 ，這些食物主要包括水果、堅果與種子。根據作者Adam Gollner，有些果食主義者只吃已經掉落的果實  。也有一些不吃榖物的人，他們相信這是不自然的作法 。有些人則認為不應食用會長成植物、堅果、種子及水果之前的一切植物的種子  。還有人相信應該只吃會在被吃掉後散播種子的植物。一些果食主義者採用植物學的定義食用包括豆科植物在內的果實。也有包括生果、果乾、蜂蜜、橄欄油在內，或食用水果、堅果、種子及巧克力的人。

The mild climate and the wonderful fruits improved my condition and gave me more faith in Nature's methods and an understanding of them, and I gained courage to try short fasts to assist the cleansing properties of fruit and climate, with such results that one morning of a well feeling day I chanced to notice in my mirror that my face had taken on an entirely new look", p. 15, "Arriving home again.... I gradually took up the ordinary diet.", p. 15, "My experience, tests, and experiments as well as cures, all showed that grape sugar of fruits was the essential material of human food, giving the highest efficiency and endurance, and at the same time was the best eliminator of debris and the most efficient healing agent known for the human body", p. 16, "To test our efficiency at exhaustive labor, we took a trip through northern Italy, walking for 56 hours continuously without sleep or rest or food, only drink.
