Raisins may provide some relief from morning sickness due to their natural sugars and fiber content, but individual experiences may vary. While some pregnant women find relief from morning sickness by nibbling on raisins, others may not experience the same benefits. Morning sickness can be triggered by various factors, and what works as a remedy can vary from person to person. If you're struggling with morning sickness, consider trying different approaches, such as consuming small, frequent meals or ginger-based remedies, in addition to incorporating raisins into your diet.
