Can orange peel be eaten directly by biting into it?
Generally speaking, whether orange peel can be eaten directly by biting into it depends on the source and processing of the orange, as well as an individual's physical condition. If discomfort occurs, medical advice should be sought promptly. The detailed analysis is as follows:

If the orange comes from a pollution-free environment, its peel is unwaxed and free of pesticide residues, and it has been thoroughly washed with the bitter white pith removed, then the peel can be eaten directly. Such orange peel is rich in dietary fiber and essential oils, offering a crisp texture with a subtle fruity fragrance. Moderate consumption can bring certain health benefits.
However, if the orange peel has been waxed, shows visible signs of pesticide residue, or has not been adequately cleaned, it should not be eaten directly. Chemical substances on these peels are difficult to remove through simple rinsing, and consuming them may irritate the gastrointestinal tract and potentially impose unnecessary strain on the body.
It is important to maintain oral hygiene before and after eating orange peel to prevent small fragments from irritating the throat. When selecting oranges, opt for varieties with clean, unwaxed peels. Wash them thoroughly under running water with gentle rubbing, using a soft-bristled brush if necessary. Consumption should be moderate—avoid excessive intake, especially for individuals with sensitive digestive systems, who should further reduce the frequency of consumption.
