What is Rambutan?
Rambutan is a flavorful, bright-red, exotic, grape-like fruit offering an array of potential health and wellness perks.
The Origins of Rambutan
Rambutan originated in the Malay Peninsula and Indonesia. It's native to Malaysia and cultivated in Puerto Rico, Central America, Thailand, Mexico, Indonesia, Australia, South China, and other Asian countries.
Rambutan grows on trees, ripening about three months after the rambutan tree flowers.
Appearance and Taste
Rambutans are bright red (sometimes yellow) with a translucent white center, resembling (and tasting like) grapes —- and its cousin fruit, lychee. Rambutan is also similar in appearance to lychee, covered in an outer peel with a seed in its center.
But what makes rambutan unique is its soft, flexible outer spines, called spinterns, which resemble hair. Depending on its growing stage, rambutan could taste sweet or mildly sour.
You can enjoy rambutan raw, cooked, or served in nutritious, mouth-watering recipes. To enjoy it raw, tear off the outer skin of a rambutan and pop out the fleshy fruit. Spit out the bitter-tasting seed or consume the seed in its baked form.
Rambutan Availability
Fresh rambutans are increasingly imported into the United States and available in grocery stores and supermarkets nationwide. They're also available fresh and canned in syrup in South East Asian and Chinese markets.
Rambutan varieties that are darker in color (vs. light-colored or pale) are the most ripe.

Health Benefits of Rambutan

The abundance of vitamin C and other antioxidants in rambutan helps support strong immune function, possibly reducing the risk of becoming ill and feeling worn down.

The seeds may also promote diabetes prevention. However, more human studies are needed to understand its potential role in metabolic health.

Medicinal Uses of Rambutan

This nutrient-dense tropical fruit has been used to diminish diarrhea, other digestive problems, and fever. Its leaves were also used as a bandage to help ease headache pain.
However, traditional use does not always equate to scientifically validated health benefits.
