orange, kiwi, guava, watermelon, cherries, apricots, papaya, and mango
bananas and apples usually fall pretty short. I avoid berries 'cause of the seeds and low sugar content, and grapefruit flavonoids are estrogenic so I stay away from them(plus they're gross imo). bananas are said to elevate serotonin, but I don't see how it could possibly make any sort of substantial difference at all, so I eat a lot of bananas because they're so cheap and tasty, but cause of their cultivation they could be allergenic and cause bloating for some along with the serotonin irritating the gut.
also, unripe fruits are to be avoided at all costs.
