Rambutan is a tasty tropical fruit that is gaining popularity around the world. With a sweet and creamy taste, rambutan is a delicious snack or addition to fruit salads. But how many of these exotic fruits should you eat in one day?
What are rambutan?
Rambutan are a type of fruit that grow in tropical areas, primarily Southeast Asia. The name “rambutan” comes from the Malay word for hair, “rambut,” referring to the hairy outer shell of the fruit. Underneath this shell is a soft, opaque white fruit with a seed in the middle. The flavor is sweet and creamy, similar to a grape. Rambutan are closely related to lychee and longan.
Fresh rambutan fruit contains about 82% water and also provides fiber, vitamins C and B3, iron, copper, potassium, magnesium, manganese, and antioxidants. The hairy shell and seed are not eaten.
Some potential health benefits of rambutan include:
- Hydration from the high water content
- Fiber for digestion and heart health
- Vitamin C for immune function and iron absorption
- Antioxidants for reducing inflammation and oxidative stress
- Potassium as an electrolyte for nerve signaling and blood pressure
Therefore, rambutan can be a healthy part of your diet when consumed in moderation.

Recommended Serving Size
There is no official recommended serving size for rambutan. Since it is a fruit, the serving size can vary based on your nutritional needs and diet. A few recommendations for rambutan serving sizes include:
- 1/2 cup or about 4-5 fruits – Good for a snack or side
- 1 cup or about 7-10 fruits – Appropriate for a light meal or dessert
- 1.5 cups or 15-20 fruits – High if you eat this amount in one sitting
The number of fruits in a cup depends on their size, which can vary. Smaller rambutan may have closer to 15 per cup, while larger ones could be 5-7 per cup.
Daily Recommendations
There are no official recommendations for how much rambutan to eat per day. However, general fruit intake recommendations can provide a guide.
The USDA Dietary Guidelines suggest the following daily amounts of fruit:
- 1 cup equivalent for children ages 1-3
- 1 – 1.5 cups for children ages 4-8
- 1.5 – 2 cups for ages 9-13
- 1.5 – 2 cups for ages 14-18
- 2 cups for adult women
- 2 cups for adult men
One rambutan fruit is about 1/2 cup equivalent. So if you eat a varied diet of different fruits, 0.5 – 2 cups of rambutan could fit into your daily recommendation.
For example, here are some daily rambutan serving ideas by age group:
- Ages 1-3: 1-2 rambutan fruits
- Ages 4-8: 2-3 rambutan fruits
- Ages 9-18: 3-4 rambutan fruits
- Women: 4-5 rambutan fruits
- Men: 4-5 rambutan fruits
Keep in mind your personal calorie needs. The above are general suggestions, but eating 5 fruits versus 2 fruits changes the calories you consume. You can adjust your portion sizes accordingly.
Weight Loss Benefits
Rambutan may support weight loss in a few ways:
- Low in calories – A one cup serving only has 75 calories
- High fiber – The 2.6 grams of fiber promotes feelings of fullness
- High water content – The hydration can help reduce overeating
- Source of manganese – This mineral is needed for metabolizing carbs and fat
By displacing higher calorie foods and providing satiety, rambutan can help reduce overall calorie intake to create a calorie deficit for weight loss.
One study in overweight adults found the following:
- Eating a pre-meal snack of lychee fruit (similar to rambutan) led to eating roughly 100 fewer calories at the meal afterwards compared to not eating a pre-meal snack.
- Feelings of fullness were stronger in the group that ate lychee compared to the control group.
Research has also shown fruits like rambutan that are high in polyphenol antioxidants may reduce obesity-related inflammation, support metabolic health, and decrease fatty liver disease.
So incorporating rambutan into a balanced, low-calorie diet can contribute to overall weight management.
Tips for Weight Loss
Here are some tips for eating rambutan as part of a weight loss diet:
- Add rambutan to a fruit salad with low-sugar fruits like berries or grapefruit sections
- Replace high-calorie desserts with a bowl of fresh rambutan
- Eat 3-4 rambutan as a mid-morning or mid-afternoon snack
- Pair rambutan with protein like yogurt or nuts to make a balanced snack
- Drink water before or after eating rambutan to increase feelings of fullness
- Measure your portion to stay within your calorie needs for the day
Diabetes Benefits
Rambutan may also benefit people with diabetes. Research suggests rambutan and similar fruits may:
- Help regulate blood sugar levels due to fiber content
- Provide antioxidants like vitamin C that are deficient with diabetes
- Reduce inflammation from the antioxidant gallic acid
- Decrease oxidative stress that can worsen diabetes complications
One human study found that eating lychee fruit significantly reduced post-meal blood sugar spikes in type 2 diabetics.
However, moderation is still important since rambutan does contain natural sugar. Following the serving size tips above can allow you to incorporate rambutan into your diet while managing your blood sugar.
Tips for Diabetes
Here are some ways to add rambutan to your diet with diabetes:
- Pair rambutan with a source of protein or healthy fat like nuts or cheese to prevent blood sugar spikes
- Time your rambutan intake by eating it as a snack between meals rather than dessert after a meal
- Monitor your portion sizes and stay within the recommended daily amounts
- Select smaller rambutan which will have less natural sugar than larger fruits
- Talk to your doctor or dietitian about fitting rambutan into your meal plan
Potential Side Effects
For most people, eating a few servings of rambutan daily is likely safe. However, there are a few considerations:
- Allergies – Rambutan come from the same family (Sapindaceae) as mangos, lychee, and pistachios. So allergies to those foods may mean an allergy to rambutan as well.
- Pesticides – Non-organic rambutan may contain pesticide residues. Opt for organic when possible or wash thoroughly before eating.
- Sugar content – While the natural sugar in fruit is generally healthy, eating a lot of rambutan may be unhealthy for diabetics or those limiting sugar.
- Bloating or gas – The fiber in rambutan may cause digestive upset like bloating, gas, or diarrhea when overeaten.
If you experience any negative side effects, stop eating rambutan. See a doctor immediately for food allergy symptoms like swelling, itching, or difficulty breathing.
During Pregnancy
Rambutan can be a healthy addition to your diet in moderation during pregnancy. Potential benefits include:
- Vitamin C for immune health
- Fiber to prevent constipation
- Potassium to reduce leg cramps
- Hydration from the water content
However, pregnant women should take precautions with rambutan including:
- Avoid eating the peel or seed which may harbor toxins
- Thoroughly wash the outer spines before eating
- Avoid eating large amounts which may cause gas or diarrhea
- Consult your OBGYN about any dietary concerns or restrictions
The fruits themselves appear to be safe for pregnant women based on research to date. But use caution and moderation when adding any new food to your diet during pregnancy.
Tips During Pregnancy
Here are some tips for eating rambutan fruit while pregnant:
- Eat only 1-2 servings daily in the first trimester when nausea is common
- Time intake between meals to prevent sugar spikes
- Pair rambutan with yogurt or cottage cheese for a balanced snack

For Children
Rambutan can also be part of a healthy diet for children in moderation. Benefits include:

In particular, the creamy sweet taste often appeals to picky eaters. However, some precautions for kids include:
- Choking hazard from the seed for very young children
- Sugar content could cause hyperactivity
- Allergies are more common in children
- Higher pesticide risk from small body size
Introduce rambutan slowly and watch for any allergic reactions. Opt for organic when possible. And follow age-appropriate serving sizes.
