> Bananas and jack-fruit are strong allergens, possibly because of their cultivation methods. Mangos, apples, and pears are allergenic to some people. Poorly ripened fruits of all sorts should be avoided. > [Safe fruits] Corossol, lychee, longan, guava, papaya, pawpaw, sapota, guanabana. Some frozen and canned fruits are good; applesauce, corossol, guanabana, longans, and lychees for example. [Forum Discussion](https://archive.ph/o/OJZkW/https://raypeatforum.com/community/threads/rp-email-advice-discussion-papaya-estrogenic.13799/) > [Salicylic acid intolerance] The fruits you mention all seriously increase [[serotonin]]. A sore throat is a quick effect, but some people get migraines from them. The pectin in raw apples causes the intestine to release [[serotonin]] into the blood, so well cooked apples have much less effect. Fruits contain almost no salicylic acid. [(Reference)](https://archive.ph/o/OJZkW/https://raypeatforum.com/community/threads/ray-peat-email-advice-depository.1035/page-6%23post-25447) > [I think you have stated that the best fruits, if properly grown, are oranges, watermelons, and grapes. Is guava close to them in quality?] Yes, they rank with oranges for their protective qualities. [I know you have mentioned that berries are not an ideal fruit because the seeds are more difficult to avoid. Do you think berries are still preferable to starches, or would the seeds in, say strawberries, be likely to make them more problematic than a starch like potatoes?] If they are eaten without pulverizing the seeds I think they are o.k.
