Guava isn’t just a delicious tropical fruit — it may also offer powerful blood sugar control benefits, making it a smart choice for people with diabetes or those looking to prevent it.
Here’s how guava can help lower blood sugar:
1. Low glycemic index (GI)
Guava has a low glycemic index, meaning it does not cause rapid spikes in blood sugar, making it a suitable fruit for people with diabetes.
2. Rich in fiber
Guava contains a large amount of dietary fiber, especially soluble, which helps to:
– slow down the absorption of sugars
– improve digestion
– prevent sudden increases in blood sugar after meals
Fiber also increases the feeling of fullness, which aids in weight control – an important factor in blood sugar regulation.
3. Rich in antioxidants and nutrients
Guava is loaded with valuable compounds such as:
– vitamin C
– potassium
– flavonoids (e.g. quercetin)
These substances can improve insulin sensitivity and reduce inflammation, which is directly linked to better blood sugar control.
4. Guava leaves – a traditional remedy
Guava leaves, when used as a tea, have been studied for their antidiabetic properties. Studies have shown that guava leaf extract can:
– lower blood sugar after meals
– inhibit certain enzymes that convert carbohydrates into glucose
– improve insulin function
