Most people associate the coconut tree with its fruit, from the refreshing water to the versatile oil and fiber-rich meat. However, a lesser-known but equally beneficial part is the tender inner core of the stem, commonly referred to as the 'heart of palm' or 'ubod' in some regions. While the outer, woody trunk is not edible, this soft, delicate core has a nutritional profile that deserves recognition.
What is Coconut Heart of Palm?
Heart of palm is a vegetable harvested from the center of certain palm trees, including the coconut palm. It consists of the innermost parts of the growing bud, young leaves, and stem tissue. It is often compared to artichoke hearts, white asparagus, or water chestnuts due to its subtle flavor and texture. Fresh heart of palm is crisp, juicy, and slightly nutty, and its taste can be influenced by how it is prepared. The practice of harvesting single-stemmed palms has faced sustainability issues in the past, but responsible and cultivated farming practices now ensure a more eco-friendly supply. This delicacy is a staple in many cuisines, often used in salads, stir-fries, and as a low-carb pasta alternative.
Nutritional Profile of Coconut Heart of Palm
Heart of palm is packed with nutrients despite being low in calories and carbohydrates. A 100-gram serving of raw heart of palm offers a significant percentage of the daily value for several essential minerals.
- High in Fiber: Provides a substantial amount of dietary fiber, which is crucial for digestive health and promotes feelings of fullness.

Health Benefits of Heart of Palm
Digestive Wellness
The high dietary fiber content aids in maintaining regular bowel movements and can help prevent constipation. A healthy intake of fiber also supports a balanced gut microbiome, contributing to overall digestive health.
Cardiovascular Support
Heart of palm is exceptionally rich in potassium, an electrolyte that plays a vital role in regulating blood pressure and heart function. A potassium-rich diet can help counteract the effects of sodium and ease tension in blood vessel walls, potentially reducing the risk of heart disease.
Weight Management
With its low-calorie and high-fiber profile, heart of palm can be a strategic food for weight loss. The fiber and water content promote satiety, helping to reduce overall calorie intake by making you feel full for longer.
Blood Sugar Control
The fiber in heart of palm can help stabilize blood sugar levels by slowing the absorption of glucose. This makes it a suitable and beneficial food for individuals managing diabetes or those looking to control their sugar intake.
Immune System Boost
The vegetable contains antioxidants, such as polyphenols, which help combat oxidative stress and neutralize harmful free radicals in the body. Additionally, it provides minerals like zinc and copper that are important for proper immune function.

Risks and Considerations
While fresh heart of palm is generally very healthy, there are a few factors to consider. Canned or jarred versions, which are the most common in stores, can be high in sodium due to the brining liquid. It is recommended to rinse canned hearts of palm thoroughly to reduce sodium content. As with any high-fiber food, a sudden increase in consumption can lead to digestive discomfort such as bloating or gas, so it's best to add it to your diet gradually. Additionally, historical concerns about unsustainable harvesting practices leading to the death of the palm tree are now largely addressed by cultivated, multi-stemmed palm farms.
