Guava is a sweet tropical fruit that may also help with blood sugar management, making it useful for people with diabetes or those trying to prevent it. The article explains several ways guava supports healthier glucose levels.

First, guava has a low glycemic index, meaning it “little leads to rapid spikes in blood sugar levels.” This makes it a safer fruit choice compared to many others. It’s also high in dietary fiber, which can “slow down sugar absorption,” improve digestion, and prevent blood sugar spikes after meals. Fiber also increases fullness, which helps with weight control — an important factor in managing diabetes.

Guava is also rich in nutrients and antioxidants. The fruit contains vitamin C, potassium, and flavonoids like quercetin, all of which may help improve insulin sensitivity and reduce inflammation, both linked to better blood sugar balance.

The article also highlights guava leaves, traditionally used as a natural remedy. Studies show that guava leaf extract may “lower blood glucose after meals,” block enzymes that turn carbs into sugar, and support insulin function. Guava leaf tea is made by boiling dried leaves for about 10 minutes.

For best results, the article suggests eating raw guava, drinking guava leaf tea, and avoiding sugary guava juices or canned versions. It also recommends moderate portions, reminding readers that even healthy fruits contain natural sugar.

Finally, the article notes that guava can support blood sugar control but does not replace medication or doctor-prescribed treatment.
