Nora PatelBananas are nature’s perfect snack—portable, sweet, and packed with nutrients. But is eating one before bed always a good idea?
While many swear by this bedtime habit for better sleep, doctors and nutritionists caution that bananas at night aren’t universally beneficial. For some, they bring calm. For others, they bring bloating, blood sugar spikes, or reflux.
So—should you keep that banana on your nightstand… or move it to breakfast?
