Chewing Gum May Boost Heart Health Benefits of Vegetables, New Study Suggests

ISLAMABAD: A new study has suggested that chewing gum after eating nitrate-rich vegetables such as beetroot, spinach, and kale may help lower blood pressure and improve heart health.

Leafy greens and root vegetables are rich in nitrates, compounds known to provide significant cardiovascular benefits. Once consumed, nitrates trigger a process in the body that helps widen blood vessels, improve blood circulation, and enhance the efficiency of energy production in muscles.

Researchers say these effects can contribute to a noticeable reduction in blood pressure, potentially lowering the risk of serious conditions such as heart attacks and strokes.

However, for nitrates to deliver these benefits, they must first be converted into another chemical called nitrite. This conversion is carried out by specific bacteria naturally present in the mouth.

Scientists from King’s College London and the University of Reading have been investigating ways to make this process more effective. During their research, they found that sweetened chewing gum may help enhance the conversion of nitrates into nitrites.

Cardiovascular specialist Andrew Webb explained that previous studies had shown that drinking grapefruit juice alongside beetroot juice reduced the acidity of saliva, which in turn affected the nitrate-to-nitrite conversion process.

“We wanted to investigate whether increasing the acidity of saliva could speed up the conversion of nitrate into nitrite,” Webb said.

As part of the study, volunteers were given a shot of beetroot juice and then asked to chew gum for several hours. Some participants received chewing gum containing higher levels of sugar, while others were given sugar-free gum.

Researchers are continuing to analyze the findings to better understand how chewing gum may influence the body’s ability to process dietary nitrates and support cardiovascular health.
