What does rambutan look like? Rambutan is quite the interesting fruit. It looks very much like an extremely hairy lychee fruit or a pink-red sea urchin with incredibly soft spines. Most cultivars bear small, oval, pink-red fruit with soft pink and bright green hairs covering the entire skin. When ripe, the skin may turn a darker red. Yellow-orange varieties exist as well. The flesh is whitish, shiny, almost see-through, very similar to that of litchi. Each fruit contains one rather pale, soft brown seed.

After 6-10 years, rambutan trees start bearing greater amounts of fruit and the view of a tree heavy with fruit is truly lovely. Rambutan fruit hang in beautiful bunches of vivid colors, sagging lazily, awaiting to be picked.

What does rambutan taste like? Again, very similar to lychee. Rambutan fruit are sweet and fragrant with a slightly acidic after-flavor. Are rambutan seeds edible? Answer: yes. Raw seeds are soft and very bitter, hence their unproven reputation as being poisonous. However, if you cook them well, they should lose most of their unpalatable bitterness. Roasted rambutan seeds taste somewhat like roasted, bitter chestnuts or like slightly bitter popcorn.

How to eat ripe rambutan? Simply put pressure on the skin of a ripe fruit and it should break easily, allowing you to take out the flesh and enjoy it. You can also cut them around the middle with a knife, pull one half of the skin and then squeeze the fruit out. If you are too eager to try them, just take a bite out of one rambutan to crack the soft skin and enjoy its delicious inside.

Rambutan

The rambutan is one very popular fruit in Southeast Asia, comparable to apples in Europe and America. For this reason it is important to know as much as possible about its nutritional value and health benefits. So here is a list of the top 5 nutrition facts and health benefits of rambutan:

1) Natural energy booster. Rambutan fruit have a high carbohydrate content (around 20%) thus contributing to boosting energy levels. Carbohydrates regulate blood sugar levels, providing energy for the body to use to perform various physical and cognitive activities. If there is a sufficient carbohydrate intake, the body does not make use of proteins for making energy. Instead, it uses them to perform essential cellular functions such as catalyzing biochemical reactions of vital importance.

2) Helps prevents constipation. With around 3 g of dietary fiber/100 g pulp, rambutan contributes to relieving constipation. Dietary fiber adds bulk to stools, encouraging their elimination. Also, the fruit has a high water content which helps us stay hydrated, preventing constipation. According to traditional Chinese medicine, eating rambutan can help kill and expel intestinal parasites, probably due to the fruit having antifungal properties.

3) Contributes to maintaining a steady weight. Rambutans have around 78 kcal/100 g. If you are looking to maintain a steady weight, you can substitute candied sweets with sweet fruits such as rambutan or lychee and significantly reduce your calorie intake.

4) Good vitamin C and manganese content. Eating a handful of rambutan fruit can supply our body with good amounts of vitamin C and manganese, two potent antioxidants which protect against oxidative stress, premature aging and chronic disease. Vitamin C in particular promotes collagen production, collagen being a protein that helps maintain the structure of our blood vessels and skin.

5) Boasts antioxdant and anticancer activity. The antioxidants in rambutan fruit were found to protect against free radical damage that can alter cells and DNA causing mutations that lead to cancer, neurodegenerative diseases and so on. In addition to vitamin C and manganese, rambutan also contains p-Coumaric acid, caffeic, ellagic and gallic acid, four polyphenols which exhibited excellent in vitro anticancer activity.

P-Coumaric acid, for instance, is suggested to help lower stomach cancer risks, while gallic acid, also found in grape seeds, may help prevent and delay the progression of neurogenerative diseases such as dementia. Caffeic and ellagic acid were also shown to be potent anticarcinogens which can help stop cancer cell proliferation. However, further studies are needed before promoting any substance as a sure and valid cancer treatment-proper.

Rambutan may not be the most nutritious fruit, yet it still provides a good addition to one’s diet. It is sweet, juicy and contains good amounts of vitamin B3 as well as antioxidants such as manganese and vitamin C. It provides good energy levels as a result of its moderate carbohydrate content. Moreover, seen that it practically has no fat, it is safe for anyone suffering from cardiovascular disease. Overall, rambutan is a good fruit to eat on a hot day when you are feeling thirsty and craving for something naturally sweet.
