Can I eat watermelon after eating a nectarine?
Generally speaking, it is acceptable to eat a moderate amount of watermelon after consuming nectarines. The detailed explanation is as follows:
For most people, eating watermelon immediately after consuming nectarines will not cause noticeable adverse reactions. Both nectarines and watermelons are fruits rich in water and vitamins; their consumption helps replenish fluids and nutrients and promotes digestion. If an individual has normal gastrointestinal function and no history of allergies or other health issues, eating watermelon after nectarines is acceptable.

Although eating nectarines and watermelon together typically does not cause adverse reactions, excessive consumption may lead to some discomfort. Nectarines contain abundant dietary fiber, while watermelons contain large amounts of water; therefore, moderation is important.
In daily life, it is recommended to consume both nectarines and watermelon in moderation, maintain healthy lifestyle habits, and pay attention to one's physical and mental well-being.
