Bland, dry foods are recommended for morning sickness because they are less likely to irritate the stomach and are easier to digest. These foods help minimize nausea and vomiting by preventing stomach upset and reducing acid reflux. Spicy, high-fat, or large meals tend to exacerbate symptoms by stimulating gastric acid secretion and delay gastric emptying. Small, frequent intake of bland foods like crackers or toast can help maintain nutritional status without worsening discomfort. This approach helps improve tolerance and symptom management during morning sickness.
