2. High in Fiber
Guava is high in dietary fiber, especially soluble fiber, which helps:

– Slow down sugar absorption

– Improve digestion

– Prevent blood sugar spikes after meals

The fiber also promotes satiety, helping with weight control — another key factor in managing blood sugar.

3. Rich in Antioxidants & Nutrients

Guava is loaded with important compounds like:

Vitamin C

Potassium

Flavonoids (like quercetin)

These may help improve insulin sensitivity and reduce inflammation, which is linked to better blood sugar control.

4. Guava Leaves: Traditional Remedy
Guava leaves, used in tea form, have been studied for their anti-diabetic properties. Research suggests guava leaf extract can:

Lower blood glucose after meals

Inhibit certain enzymes that convert carbs into glucose

Improve insulin function

How to Use Guava for Blood Sugar Control
Eat the fruit raw (with the skin, if pesticide-free)

Drink guava leaf tea (boil dried leaves in water for 10 minutes)

Avoid sugary guava juices or canned varieties

Stick to moderate portions — even healthy fruits contain natural sugars

Note:
While guava can support blood sugar control, it does not replace medication or doctor-recommended treatment.
