Quais são os benefícios de comer Rambutan?

O Rambutan é rico em antioxidantes que combatem os radicais livres e previnem qualquer doença que eles possam causar. Isso inclui câncer, inflamação e até doenças cardíacas. A abundância de certas vitaminas e o sabor delicioso tornam esta fruta obrigatória no prato.

1. Pode ajudar no tratamento da diabetes

Um estudo chinês fala sobre como as cascas de rambutan possuem propriedades antidiabéticas. Camundongos diabéticos induzidos com extrato fenólico de cascas de rambutan mostraram redução nos níveis de glicose no sangue em jejum (1).

2. Pode prevenir o ganho de peso

Não há pesquisas específicas que sugiram como o rambutan, por si só, pode prevenir o ganho de peso. Porém, frutas, em geral, conforme estudos, podem prevenir o ganho de peso por apresentarem baixa densidade energética (2). As frutas também contêm certa quantidade de fibra que pode ajudar na perda de peso, ajudando você a ficar satisfeito por mais tempo.

3. Melhora a saúde do coração

O alto teor de fibra no rambutan pode reduzir potencialmente o risco de doença cardíaca coronária (3). Também ajuda a aliviar a hipertensão e pode reduzir os níveis de colesterol - ambos os quais podem causar danos ao coração.

4. Melhora a saúde óssea

The phosphorus in rambutan has a role to play here. The fruit contains good amounts of phosphorus, which aids in the formation of bones and their maintenance.

The vitamin C in rambutan also contributes to bone health.

5. May Help Prevent Cancer

Rambutan is one of those fruits with a high antioxidant content, which is reason enough to say that it can prevent cancer. These antioxidants can fight inflammation and protect the cells in the body from getting affected.

The vitamin C in the fruit also aids in this regard. It neutralizes the harmful free radicals and offers protection against different forms of cancer.

According to one study, rambutan peels can alter and disturb the growth of cancer cells and can even be used for the treatment of liver cancer (4). And as per another report, eating five rambutans every day can drastically cut the risk of cancer (5).

6. Has Antibacterial And Antiseptic Properties

Studies suggest that rambutan has been used since the ancient times for its antibacterial properties (6). Certain studies also speak of the antiseptic properties of the fruit, which protect the body against numerous infections. The fruit accelerates wound healing and also prevents pus formation.

7. Boosts Energy

Rambutan contains both carbohydrates and protein, both of which can offer an energy boost when required. The natural sugars in the fruit also aid in this aspect.

8. Improves Digestive Health

The fiber in rambutan might help improve digestive health. It can aid digestion and also help prevent digestive issues like constipation. And the antibacterial properties might help kill intestinal parasites. Thus treating diarrhea as well.

However, we have less research in this regard. Please consult your doctor.

9. Works As An Aphrodisiac

Certain sources say that the leaves of rambutan work as an aphrodisiac. Simmering the leaves in water and then consuming them is said to activate the hormones that boost libido.

Rambutan is also believed to enhance fertility, though there is no research to back this up. Check with your doctor before using it for this purpose.

10. Promotes Scalp And Hair Health

The antibacterial properties of rambutan might treat dandruff and other scalp issues like itching. And the vitamin C in the fruit can nourish the hair and scalp.

The copper in rambutan treats hair loss. It also intensifies hair color and prevents premature graying.

Rambutan also contains protein, which can strengthen the hair roots. Vitamin C can also give your hair that added shine. You can simply apply rambutan juice to your hair and let it sit for about 15 minutes before shampooing as usual.

As there is little research in this aspect, we recommend you consult your doctor before you use rambutan for your scalp/hair health.

11. Enhances Skin Health

The seeds of the rambutan fruit are known to enhance your skin’s health and appearance. Mash the seeds into a paste and apply it to your skin for a clearer and even complexion. Using the seed paste regularly can soften and smoothen your skin and improve its texture.

Rambutan also hydrates your skin. The manganese in the fruit, along with the vitamin C, aids collagen production and also acts as an antioxidant that damages the free radicals. All of this keeps your skin healthy and young for a long time.

That’s pretty much the list of benefits. But there is a big question running around. Did you ever wonder if rambutan is the same as lychee? Let’s find out.

Rambutan Vs. Lychee – What’s The Difference?

Firstly, the two are different. Let’s accept that.

Rambutan

The rambutan is about the size of a golf ball. It has a red outer skin and yellowish green spikes all over. The flesh of this fruit is white and has a big seed at its center. It has a sweet, creamy, rich taste.

The skin is really thick and hard to peel.

Lychee

The lychee is a little smaller than rambutan. It also has a red outer skin but minus the spikes. And the skin is rough. The flesh looks similar to that of the rambutan, but it tastes different. It is not as rich and creamy. It is crisper. And yes, this one also has a seed at the center.

The skin is not as thick, and you can peel it as you do with a hard boiled egg.

So, is that all? Is that all there is to rambutan? Well, no. There’s a host of other things you can do with the plant.

How Else Can You Use Rambutan?

We already saw how to use the fruit and its benefits. But that’s not it. There are other parts of the plant that are quite useful as well. These include the leaves, seeds, peel, and the bark. And here, we look at each of them.

The Leaves

The leaves of the fruit contain healing juices. They possess analgesic properties, which basically means they act as an effective painkiller. It is said that drinking the juice works on your nerve centers and heals pain.

The juice from the leaves also offers great scalp health. You can also get rid of frizzy hair – just squeeze the juice from the leaves and apply to your scalp and hair. Rinse after an hour. Repeat 3 times in a week.

The Seeds

The seeds also have numerous beneficial properties, but we suggest never to eat them raw. They contain saponins, compounds that can be extremely poisonous.

The seeds are full of proteins and carbs. Adding them to your snack can be a good idea. They also have oxidative properties, which can help remove blemishes from your skin. You just have to crush the seeds to make a fine paste and apply to your skin.

The Peel

The peel contains flavonoids and gallic acid – these contain anti-cancer and anti-inflammatory properties. You can simply wash the peels and eat them raw. And don’t worry about the spines – they are just soft and tender.

The peel can also cure dysentery and fever. Just boil the peel and strain the liquid. Drink this twice or thrice a day.

The Bark

The bark of the rambutan plant has astringent properties and can treat canker sores.

See? We told you. Not just the fruit, even the plant and its parts have some use. Now that’s cool, isn’t it? What’s even better are the facts about the fruit.

Selection

While buying rambutans, look for the fresh ones that are bright red or yellow. The spines should be firm. Never choose a rambutan with bruises as it may be a sign of a damaged or overripe fruit.

Any Tips For Cooking?

• Before you even use rambutan for cooking, make a cut through the skin all the way round. Post which you can peel off the skin and use it.
• In case you are serving the fruit to your guests, you can retain half of the skin on the platter. This enhances the look of the fruit. Your guests can then peel the fruit and eat.

How To Eat Rambutan Properly?

We know it’s a tricky task, but we have you covered.

• The first step is to choose a ripe rambutan. A ripe rambutan is bright red with green spikes.
• Place the fruit on a cutting board, and using a kitchen knife, just cut through the tough rind. Don’t try to cut the fruit in half because, well, you can’t. There is a large seed at the center.
• Hold the knife stationary and slowly rotate the fruit. This will ensure some part of the ring is peeled off.
• Squeeze out one half of the rind with your fingers.
• You can either squeeze out the other half of the rind, or if you are worried about the loss of juice, just peel the rind.
• Ensure you dispose the seed before eating the fruit.

Okay. So now, you are relishing the fruit. You are happy. But wouldn’t it only get better if you add this fruit to some delicious recipe(s)?

Does Rambutan Have Any Side Effects?

Most of the side effects come from the fact that the fruit is sweet.

Diabetes

Yes, we did speak of rambutan for its anti-diabetic properties. But there is another side to it. Rambutan contains fructose, and this can promote insulin resistance, worsening diabetes. It can cause a spike in the blood sugar levels when taken in excess.

Note: The fiber in rambutan regulates blood sugar release, making it a great choice (in moderation) for those with blood sugar imbalances.

Hypertension

In case you let the fruit ripen too much, the sugar in the fruit can turn into alcohol. And this can pose harm to people with blood pressure problems.

Toxicity

This is with the seeds. Eating them can be fatal. Hence, don’t eat them.

The fruit is harvested between July to September and December to January – July to September being the main period.
