To be precise, all fruits with soft skins are edible. There are more vitamin C, pectin and cellulose in fruit skin than in pulp, so it was once advocated not to peel fruit. But in recent years, with the development of agriculture and forestry, pesticides have been widely used. Some highly toxic pesticides will penetrate into the fruit when sprayed on it, and most of them will remain in the peel. So the fruit should be washed and peeled before eating.
