The fruits also contains ‘jambosine’, a type of alkaloid that has had positive results in blocking or regulating the conversion of starch to sugar. Research is currently underway to determine the effect of jambosine on blood sugar levels. There has also been evidence to show that jambu has antimicrobial and antifungal effects as well, and its richness in vitamin C allows for a stronger immune system, and prevention of various skin infections. The high fibre content of the fruit also helps in preventing serious health conditions in the digestive system.
