Side Effects, Nutritional Content
and Proper Processing
for Optimal Results


Duku (Lansium domesticum) is a tropical fruit native to Southeast Asia, widely loved for its sweet, slightly tangy flavor and refreshing juice. Beyond its small size, duku is packed with essential nutrients that support overall health and well-being.

A. Nutritional Profile of Duku
Duku is a powerhouse of vitamins and minerals. Every 100 grams of duku fruit typically contains:
  • Energy: Approximately 63–70 kcal.
  • Fiber: Essential for a healthy digestive system.
  • Vitamin C: A potent antioxidant for the immune system.
  • B Vitamins: Specifically Vitamin B1 (Thiamine) and Vitamin B2 (Riboflavin).
  • Minerals: Potassium, calcium, phosphorus, and iron.
  • Antioxidants: Contains flavonoids that combat oxidative stress.

B. Health Benefits of Duku
Consuming duku in moderation can provide several significant health advantages:

1. Supports Digestive Health
The high fiber content in duku promotes regular bowel movements and prevents constipation. This fiber also acts as a natural prebiotic, fueling the good bacteria in your gut.

2. Boosts the Immune System
Rich in Vitamin C, duku strengthens the body’s defense against viruses and bacteria while accelerating the healing process for wounds and infections.

3. Promotes Skin Health
The antioxidants in duku help prevent premature aging by neutralizing free radicals that damage skin cells. The combination of Vitamin C and trace Vitamin E helps maintain a natural glow.

4. Regulates Cholesterol and Heart Health
The soluble fiber in duku helps bind bad cholesterol in the digestive tract. Furthermore, its potassium content is vital for maintaining stable blood pressure levels.

5. Enhances Energy Metabolism
The B-complex vitamins found in duku assist the body in efficiently converting carbohydrates into energy, helping to prevent fatigue during daily activities.

C. Side Effects of Consuming Duku
While duku is healthy, overconsumption or improper intake can lead to certain issues:
  • Bloating and Gas: Due to its fiber and fructose content, eating too many duku fruits at once can cause flatulence or abdominal discomfort.
  • Weight Gain: Duku contains natural sugars. Excessive consumption can lead to an unintentional increase in daily calorie intake.
  • Diabetes Considerations: People with diabetes should limit their intake, as the natural sugar content can cause a rapid spike in blood glucose levels.
  • Sap Sensitivity: Unripe duku contains sap that may cause itching or irritation in the throat or on the lips for sensitive individuals.
D. Proper Processing and Consumption
for Optimal Results
To get the most out of duku while avoiding side effects, follow these tips:
  1. Eat Fresh: The best way to consume duku is raw and fresh. Since Vitamin C is heat-sensitive, eating it raw ensures you get the full nutritional value.
  2. Avoid Biting the Seeds: Duku seeds contain alkaloid compounds that are extremely bitter and can cause nausea or stomach upset if consumed in large amounts.
  3. Choose Fully Ripe Fruit: Select duku with a clean, yellowish-tan skin. Avoid fruits with soft, soggy black spots. Ripe fruit has lower acidity, making it gentler on the stomach.
  4. Wash the Skin Before Peeling: Even though the skin isn't eaten, washing the fruit prevents dirt or residues from transferring to the flesh during peeling.
  5. Practice Portion Control: A recommended serving is about 10–15 pieces per day to enjoy the benefits without consuming excessive sugar.
Important Note: If you have specific medical conditions such as diabetes or kidney issues, it is advisable to consult your doctor regarding the safe portion of duku for your diet.
