One of guava’s main advantages lies in its low glycemic index (GI). Foods with a low GI release sugar slowly into the bloodstream, preventing rapid spikes in blood sugar. In addition, guava is packed with dietary fiber, particularly soluble fiber, which further helps slow down sugar absorption during digestion. This process not only stabilizes blood sugar but also enhances digestion and keeps you feeling full longer — aiding in weight control, which is a crucial part of managing diabetes.

Beyond fiber, guava is rich in vitamins, minerals, and antioxidants that play a key role in maintaining healthy blood sugar levels. Nutrients such as vitamin C, potassium, and flavonoids like quercetin may improve insulin sensitivity and reduce inflammation — both of which are important for overall metabolic health. These compounds help the body use insulin more effectively, reducing the risk of long-term complications related to high blood sugar.

Interestingly, it’s not just the fruit that offers benefits — guava leaves have also been traditionally used to help control blood sugar. When brewed into tea, guava leaves may help lower blood glucose after meals, slow carbohydrate conversion into sugar, and support better insulin function. To enjoy guava’s benefits safely, choose fresh fruit over processed juices, enjoy guava leaf tea, and always consult a healthcare professional before making dietary changes or using herbal remedies alongside prescribed treatments.
