Can people with high blood sugar and poor heart health eat onions?

People with high blood sugar and poor heart health can consume onions. Onions have a very low sugar content and are rich in dietary fiber, which helps slow down sugar absorption. They also contain quercetin, a compound that enhances capillary resistance, lowers blood pressure and blood lipid levels, and helps prevent cardiovascular disease. Thus, consuming onions offers significant benefits for individuals with elevated blood sugar and compromised cardiac function. However, excessive intake should be avoided, as it may lead to excess caloric intake—potentially raising blood sugar—and may also irritate the stomach.
