Contributing to blood sugar control
Star fruit contains fiber such as cellulose and pectin. Fiber in the diet in general can contribute to slowing down the digestion and absorption of carbohydrates, thereby limiting the rapid increase in blood sugar after meals.
Some laboratory and animal studies have also recorded compounds or extracts from star fruit that can affect mechanisms related to glucose and insulin metabolism. However, these results are not enough to confirm that eating star fruit has the effect of lowering blood sugar in humans.
People with diabetes or high blood sugar still need to follow a diet, exercise, monitor blood sugar and use medication according to the instructions of medical staff.
Star fruit and blood fat
Star fruit contains vitamin C, gallic acid and some antioxidant compounds. Some preclinical studies have noted that fiber or components from star fruit can affect cholesterol and lipid metabolism.
Supplementing fiber from star fruit contributes to increasing cholesterol excretion and reducing fat accumulation in the liver.
However, there is not enough clinical evidence to confirm that eating star fruit can reduce cholesterol, triglycerides, or fat accumulation in the liver.
Therefore, people with dyslipidemia should not use star fruit as a substitute for the recommended diet, exercise or medication.
