Insoluble fiber adds bulk to stool and speeds up intestinal movement
Soluble fiber (like pectin) forms a gel that helps stabilize digestion
Together, they support smoother bowel movements, reduce constipation, and promote a healthier gut environment. Many people notice improved regularity after eating guava consistently.
3. Lower Post-Meal Blood Sugar — due to pectin + guava leaf compounds
The pectin in guava slows the absorption of glucose in the gut. This helps prevent sharp spikes in blood sugar after meals.
Guava leaf extracts, rich in flavonoids and other bioactives, have been shown in some studies to:
Improve insulin sensitivity
Lower post-meal glucose levels
Support metabolic health
Important: These effects are supportive, not a replacement for prescribed diabetes medications.
4. Heart-Health Benefits — from fiber, potassium, and antioxidants
Guava supports cardiovascular health in several ways:
Its fiber can help reduce LDL (“bad”) cholesterol
Its potassium helps regulate blood pressure and maintain normal heart rhythm
Its antioxidants reduce oxidative damage to arteries
Together, these nutrients may help lower the risk of heart disease when guava is part of a balanced diet.
5. Anti-Inflammatory & Antimicrobial Effects — due to plant phytochemicals
Guava leaves and peel contain compounds such as:
Polyphenols
Flavonoids
Tannins
