RRI.CO.ID, Jakarta - Snake fruit, better known as “Salak” in Indonesia, is a unique tropical fruit native to Java and Sumatra. The fruit is packed with essential nutrients, making it a fruit that offers a variety of health benefits.

According to medical information from Halodoc.com, here are some of the potential health benefits of Salak:

1. Supports Digestive Health

One of the most common myths about salak is that it causes constipation. In fact, salak is unlikely to cause constipation as long as you eat the thin edible membrane covering the fruit's flesh. This membrane is rich in dietary fiber and tannins.

Dietary fiber adds bulk to stool and stimulates intestinal peristalsis, helping food move smoothly through the digestive tract. Meanwhile, the tannins in salak have natural anti-diarrheal properties that may help relieve mild diarrhea by reducing inflammation in the intestinal lining.

However, if you experience severe digestive problems, persistent abdominal pain, or prolonged diarrhea, it is important to seek medical evaluation rather than relying solely on dietary remedies.

2. May Help Regulate Blood Sugar Levels

For people who are genetically predisposed to or at high risk of developing type 2 diabetes, salak may be a suitable fruit choice.

Salak has a relatively low glycemic index. In addition, studies have found that salak peel contains a compound called pterostilbene, which has mild blood sugar-lowering (hypoglycemic) properties.

The antioxidants in salak may also help regenerate damaged pancreatic beta cells, which are responsible for producing insulin. Improved insulin production may help the body regulate blood glucose levels more effectively.

3. Supports Heart Health

Cardiovascular health depends heavily on maintaining proper electrolyte balance, particularly potassium.

Salak is an excellent source of potassium, a mineral that acts as a natural vasodilator by relaxing blood vessels and reducing tension in arterial walls.

As blood vessels widen, circulation improves and blood pressure may decrease. This helps reduce the heart's workload and may lower the risk of hypertension, heart attack, and stroke.

4. Helps Maintain Eye Health

Although carrots are often associated with eye health, salak also contains a meaningful amount of beta-carotene.

Beta-carotene is an antioxidant pigment that the body converts into vitamin A, an essential nutrient for maintaining a healthy cornea and producing rhodopsin—the protein that enables vision in low-light conditions and helps prevent night blindness.

The antioxidants found in salak may also help slow age-related macular degeneration and reduce the risk of cataracts.

Tips for Getting the Most from Salak

• Do not remove the thin edible membrane, as it contains the highest concentration of fiber and nutrients.

• Wash the outer skin thoroughly before peeling to prevent dirt and bacteria from contaminating the fruit.

• Consume in moderation. Eating two to three fruits per day is generally sufficient to enjoy the benefits without potentially irritating the stomach.

5. May Support Brain Function and Memory

Salak is sometimes referred to by nutrition researchers as the "memory fruit."

This nickname comes from its high potassium and pectin content. Potassium helps improve oxygen delivery to the brain through healthy blood circulation, which may enhance concentration, alertness, and memory.

Meanwhile, pectin and other antioxidant compounds help protect nerve cells from oxidative stress, a contributing factor in neurodegenerative diseases such as Alzheimer's disease.

6. May Aid Weight Loss

If you're following a calorie-controlled diet, salak can be a satisfying snack option.

Its high fiber content slows digestion, helping you stay full for longer and reducing hunger and sugar cravings.

In addition, the carbohydrates in salak provide a gradual release of energy, helping maintain energy levels even while reducing daily calorie intake.

7. Strengthens the Immune System

Salak is rich in vitamin C and polyphenol antioxidants, making it a valuable addition to an immune-supportive diet.

These antioxidants help neutralize free radicals generated by air pollution, unhealthy foods, and ultraviolet (UV) radiation.

Vitamin C also promotes the production of white blood cells (leukocytes), which play a key role in defending the body against bacterial and viral infections. As a result, regular consumption of salak as part of a balanced diet may help strengthen the immune system, particularly during seasonal changes.

For the best results, these benefits should be combined with an overall healthy lifestyle, including a balanced diet, regular exercise, adequate sleep, and proper hydration.
