Brussels sprouts are not known to be a common trigger for heartburn. However, individual sensitivities can vary, and certain factors like overeating, consuming them in large quantities, or combining them with other heartburn-triggering foods or spices may contribute to heartburn symptoms in some people. Additionally, the high fiber content in Brussels sprouts could potentially cause digestive discomfort or gas in some individuals. If you experience heartburn or digestive issues after consuming Brussels sprouts, it's best to listen to your body and consider reducing your intake or trying different cooking methods to see if it helps alleviate the symptoms. Consulting with a healthcare professional can provide personalized advice regarding your specific dietary concerns.
