In addition, guava contains antioxidants and important nutrients such as vitamin C, potassium, and plant flavonoids. These compounds are linked to reduced inflammation and improved insulin sensitivity, which may support healthier long-term blood sugar regulation.
Not only the fruit itself but also guava leaves have attracted interest. Traditionally used in herbal teas, guava leaf extracts are now being studied for their potential to reduce post-meal blood sugar spikes and support better glucose control over time.
Some research suggests that compounds in guava leaves may slow enzymes responsible for breaking down carbohydrates into glucose. This could help minimize sharp increases in blood sugar after eating, especially when combined with a balanced diet.
