Rambutan: A Nutritional Powerhouse
Rambutan, a tropical fruit, boasts a spiky exterior that conceals a juicy, sweet flesh. A 100-gram serving offers approximately 75 calories, making it a low-calorie yet nutrient-rich option.
Vitamins and Minerals
Rambutan is a source of essential nutrients.
- Vitamin C: This powerful antioxidant helps protect cells from damage caused by free radicals. It also supports the immune system by promoting white blood cell production.
- Copper: This trace mineral is essential for maintaining cells in the bones, brain, and heart.
- Iron: Rambutan contains a modest amount of iron, important for red blood cell production and oxygen transport.
- Other Minerals: The fruit also contains smaller amounts of phosphorus, potassium, magnesium, and zinc.
Fiber's Role in Digestion
Rambutan provides both soluble and insoluble dietary fiber.
- Insoluble fiber: Aids in preventing constipation and promoting regular bowel movements.
- Soluble fiber: Acts as a prebiotic, nourishing beneficial gut bacteria and reducing inflammation.
Antioxidants and Plant Compounds
Rambutan contains antioxidants and beneficial plant compounds. Flavonoids, tannins, and phenolic compounds in the flesh, peel, and seeds show potential anti-inflammatory and anti-cancer properties. Consuming the edible flesh is the safest way to obtain these benefits.

- Weight Management: Low in calories and high in water and fiber, rambutans promote fullness and can reduce food intake.
- Immune Function: The high vitamin C content supports the production of white blood cells, strengthening the body's defenses.
- Digestive Health: The combination of soluble and insoluble fiber supports gut health and can alleviate constipation.
- Heart Health: Potassium in rambutan helps regulate blood pressure, while the fiber can help lower cholesterol levels.

Safe Rambutan Consumption
Consume only the ripe fruit's flesh. Avoid eating unripe fruit, peel, and seeds. The peel and seeds may contain toxic compounds.
A moderate intake of 4-6 fresh rambutans daily is considered safe. Pregnant women with gestational diabetes should be mindful of the fruit's sugar content and consult with their doctor. Canned rambutans often contain sugary syrup, increasing calorie and sugar intake.
