This vitamin stimulates the production and activity of white blood cells, enhancing the body’s ability to fight off infections and diseases. Vitamin C also supports the skin’s barrier function, the body’s first line of defense against pathogens.
The fruit contains other antioxidants like gallic acid and quercetin, which further strengthen the immune system by neutralizing harmful free radicals. These compounds may help reduce inflammation and oxidative stress throughout the body.
Promotes Digestive Health
Carambola is an excellent source of dietary fiber, promoting healthy digestion and regular bowel movements. A medium-sized fruit contains about 3 grams of fiber, contributing to the daily recommended intake.
The insoluble fiber in star fruit adds bulk to stool, preventing constipation and supporting gut health. Soluble fiber acts as a prebiotic, feeding beneficial gut bacteria and promoting a balanced microbiome.
Star fruit’s high water content (about 90%) combined with its fiber helps maintain proper hydration and supports the digestive process. This can aid in preventing digestive issues like bloating and indigestion.
Contributes to Weight Management
With its low calorie content and high fiber, carambola can be a valuable addition to a weight management diet. A medium-sized fruit contains only about 30 calories, making it a satisfying low-calorie snack.
The fiber in star fruit promotes feelings of fullness, potentially reducing overall calorie intake. This can help control appetite and prevent overeating.
Carambola’s natural sweetness can satisfy sugar cravings without the addition of refined sugars. Its high water content also contributes to a feeling of fullness, supporting weight management efforts.
Aids in Skin Health
The vitamin C in carambola plays a crucial role in collagen synthesis, essential for maintaining skin elasticity and a youthful appearance. Collagen is a protein that provides structure to the skin and helps prevent sagging.
Carambola’s antioxidants protect skin cells from damage caused by UV radiation and environmental pollutants. This may help prevent premature aging and maintain a healthy complexion.
The fruit’s high water content helps keep the skin hydrated, which is essential for maintaining its barrier function and preventing dryness. Proper hydration can also give the skin a plump, healthy appearance.
