Rambutan (Nephelium lappaceum L.): The nutritional and functional properties

Rambutan (Nephelium lappaceum L.) is a tropical fruit that grows naturally in Southeast Asia, most especially in the Philippines, particularly in Visayas and northern Luzon regions. This fruit has a special outer skin and a sweet, delicious core, which people like not just the taste, but also because of its health and medicinal benefits. Rambutan contains essential nutrients such as glucose, potassium, calcium, fiber, and B vitamins, which help keep the body healthy. The peel also has useful substances such as tannins, carbohydrates, flavonoids, and phenolic compounds, thereby helping protect the body from damage and reduce inflammation. The seeds possess some good properties, such as antibacterial, antifungal, and other pharmaceutical benefits. In addition, rambutan could help with diabetes, cancer, and other diseases. Some chemicals found in rambutan such as ellagic acid, corilagin, and geraniin, have shown potential in medicine. However, there are some problems to overcome, including the outer coating of the seeds which may be harmful, and getting certain active ingredients from the fruit is difficult and expensive. Despite these, rambutan remains a potential source of both food and medicine. Further studies are needed to make full use of all its benefits.
