Quick Answer: What Is the Nutrition of Hearts of Palm?
Hearts of palm are a low-calorie vegetable (about 28 kcal per 100 g) that provide roughly 2.5 g of protein, 4.6 g of carbohydrates (including 1.5–2.4 g of fiber), and less than 0.5 g of fat. They are naturally cholesterol-free, low in sugar, and supply potassium, zinc, phosphorus, copper, vitamin B6, and folate. Their protein-to-calorie ratio is notably high for a vegetable, and their mild flavor makes them versatile across many dishes. Canned versions are the most common form and should be rinsed to reduce added sodium.
What Is the Nutrition of Hearts of Palm?
Hearts of palm come from the inner core—or apical meristem—of certain palm trees. The harvested cylinder is sweet-tasting and tender, and when sourced from cespitose (clumping) palm species such as Bactris gasipaes or Euterpe oleracea, the harvest does not kill the tree, making it a more sustainable source of this vegetable. From a nutritional standpoint, hearts of palm sit in a unique category: they behave like a starchy vegetable in texture but carry a nutritional profile closer to a fibrous, low-energy-density vegetable.
The nutrition of hearts of palm centers on three standout traits: low caloric density, meaningful protein for a vegetable, and a solid micronutrient package. Unlike many vegetables that offer either fiber or protein in isolation, hearts of palm deliver both. This makes them especially appealing for people following plant-based diets, low-carbohydrate meal plans, or anyone looking to increase vegetable intake without adding substantial calories.
Most commercially available hearts of palm are sold canned or jarred in brine. The preservation process can influence the final sodium content, but the core nutritional values—protein, fiber, minerals, and B vitamins—remain largely intact. Fresh hearts of palm are harder to find outside tropical regions but offer the same nutritional benefits with naturally lower sodium.
Hearts of Palm Nutrition: Complete Macronutrient Profile
Understanding the macronutrient breakdown is essential for anyone tracking intake for weight management, athletic performance, or medical reasons. Here is the full macronutrient profile per 100 grams of raw hearts of palm:
| Nutrient | Amount per 100 g | Significance |
|---|---|---|
| Calories | 28 kcal | Very low; suitable for calorie-controlled diets |
| Protein | 2.5 g | High for a non-starchy vegetable |
| Total Carbohydrates | 4.6 g | Primarily complex carbs with minimal sugars |
| Dietary Fiber | 1.5–2.4 g | Supports digestion and satiety |
| Sugars | < 1 g | Naturally very low in sugar |
| Total Fat | 0.4 g | Minimal; virtually fat-free |
| Saturated Fat | < 0.1 g | Negligible |
| Water | ~90 g | High water content supports hydration |
Protein Content in Hearts of Palm
Few non-starchy vegetables deliver more than 2 grams of protein per 100-gram serving, yet hearts of palm do exactly that. The 2.5 grams of plant protein per serving may seem modest, but it adds up quickly when hearts of palm are used as a pasta replacement or salad topper. For individuals on plant-forward diets, every gram of protein from whole-food sources matters, and hearts of palm provide it without the higher caloric load of legumes or grains.
The protein in hearts of palm contains a range of amino acids, though—like most plant proteins—it is not considered a complete protein on its own. Pairing hearts of palm with complementary protein sources such as quinoa, legumes, or nuts rounds out the amino acid profile across a meal.
Carbohydrates and Fiber
With roughly 4.6 grams of total carbohydrates per 100 grams—of which about half comes from dietary fiber—hearts of palm fit comfortably into low-carbohydrate eating patterns. The net carbohydrate count sits around 2–3 grams per serving, making this vegetable a staple for keto and paleo enthusiasts who use it to create noodle alternatives and rice substitutes.
The fiber fraction includes both soluble and insoluble types. Soluble fiber forms a gel-like substance in the digestive tract and may help modulate cholesterol levels, while insoluble fiber adds bulk to stool and promotes regular bowel movements. This dual-fiber benefit is one reason the nutrition of hearts of palm deserves attention beyond the calorie count.
Fat Profile
Hearts of palm are naturally almost fat-free, with less than half a gram of total fat per 100-gram serving. The trace fats present are primarily unsaturated. This makes them an ideal base for dishes where you control the fat source—drizzling olive oil, adding avocado, or tossing with nuts—without worrying about hidden saturated fat from the vegetable itself.
Essential Vitamins and Minerals in Hearts of Palm
Beyond macronutrients, the micronutrient density of hearts of palm is where they genuinely shine. The following table summarizes the key vitamins and minerals found in a standard 100-gram serving:
| Micronutrient | Approximate Amount per 100 g | Primary Function |
|---|---|---|
| Potassium | ~180 mg | Fluid balance, nerve signaling, blood pressure regulation |
| Zinc | ~0.5 mg | Immune function, wound healing, DNA synthesis |
| Phosphorus | ~65 mg | Bone mineralization, energy metabolism |
| Copper | ~0.1 mg | Iron metabolism, connective tissue formation |
| Vitamin B6 | ~0.1 mg | Protein metabolism, neurotransmitter synthesis |
| Folate | ~10 mcg | DNA synthesis, red blood cell formation |
| Riboflavin (B2) | ~0.1 mg | Energy production, cellular function |
| Calcium | ~18 mg | Bone health, muscle contraction |
| Iron | ~0.5 mg | Oxygen transport, energy metabolism |
| Magnesium | ~10 mg | Muscle relaxation, enzymatic reactions |
Potassium stands out as one of the most meaningful minerals in hearts of palm. A 100-gram serving contributes roughly 180 milligrams toward the recommended daily intake of 3,500–4,700 milligrams. While this is not a massive amount compared to potassium-rich foods like bananas or potatoes, it adds meaningful variety to the dietary potassium pool—especially for individuals who struggle to consume enough potassium-rich vegetables.
Zinc and copper, though present in smaller amounts, play critical roles in immune defense and enzymatic activity. The combination of B vitamins—particularly vitamin B6, folate, and riboflavin—supports energy metabolism at the cellular level, helping the body convert food into usable fuel efficiently.
Palm Hearts Benefits for Health
The nutrition of hearts of palm translates into several evidence-supported health benefits. While hearts of palm are not a miracle food, their consistent inclusion in a balanced diet can contribute meaningfully to overall wellness. Here are the key palm hearts benefits worth knowing.
Supports Digestive Health
The fiber content in hearts of palm—roughly 1.5 to 2.4 grams per 100-gram serving—promotes regular bowel movements and feeds beneficial gut bacteria. Dietary fiber acts as a prebiotic, meaning it serves as fuel for the microbiota residing in the colon. A well-nourished gut microbiome is linked to improved immune function, reduced systemic inflammation, and better nutrient absorption. Including fiber-rich vegetables like hearts of palm regularly helps maintain this delicate ecosystem.
Aids Weight Management
With only 28 calories per 100 grams, hearts of palm rank among the least energy-dense vegetables available. The combination of low calories, meaningful fiber, modest protein, and high water content makes them exceptionally filling relative to their energy contribution. Replacing higher-calorie ingredients—such as pasta, rice, or starchy side dishes—with hearts of palm can reduce the total caloric load of a meal without shrinking portion sizes, a strategy supported by volumetrics-based approaches to weight management.
Promotes Heart Health
Hearts of palm contribute to cardiovascular wellness through multiple mechanisms. The potassium content helps counterbalance dietary sodium and supports healthy blood pressure regulation. The fiber fraction—particularly soluble fiber—may assist in maintaining healthy cholesterol levels when consumed as part of a diet low in saturated fat. Additionally, hearts of palm are naturally free of cholesterol and contain negligible saturated fat, making them a heart-friendly food by default. While palm oil itself contains compounds that have been studied for potential cardiovascular effects, it is important to distinguish palm oil from hearts of palm—they come from entirely different parts of the palm and have vastly different nutritional profiles.
Supports Bone Strength
Calcium, phosphorus, magnesium, and copper—all present in hearts of palm—are integral to bone mineralization and maintenance. While the amounts per serving are moderate, regular consumption of a diverse array of mineral-containing vegetables contributes to the total dietary mineral pool that bones depend on. Phosphorus, at roughly 65 milligrams per 100 grams, is particularly noteworthy because it works alongside calcium to form the hydroxyapatite crystals that give bones their rigidity.
May Help Blood Sugar Regulation
The low glycemic impact of hearts of palm—thanks to minimal sugars and the presence of fiber—makes them suitable for individuals managing blood glucose levels. Fiber slows the rate at which carbohydrates are digested and absorbed, blunting post-meal blood sugar spikes. For people with insulin resistance or type 2 diabetes, substituting hearts of palm for higher-glycemic foods like white rice or regular pasta can be a practical dietary adjustment.
How the Nutrition of Hearts of Palm Compares to Other Vegetables
Placing hearts of palm alongside other commonly consumed vegetables highlights their unique nutritional positioning. The table below compares key nutritional parameters across several vegetables, including artichokes—a vegetable with a similarly tender texture and culinary versatility. For more detail on artichoke nutrition, you can explore the nutritional facts about artichokes profile.
| Vegetable (per 100 g) | Calories | Protein | Fiber | Carbs | Notable Strength |

| Hearts of Palm | 28 | 2.5 g | 1.5–2.4 g | 4.6 g | Protein-to-calorie ratio |
| Artichoke Hearts | 47 | 3.3 g | 5.4 g | 10.5 g | Fiber density |
| Asparagus | 20 | 2.2 g | 2.1 g | 3.9 g | Lowest calorie density |
| Celery | 14 | 0.7 g | 1.6 g | 3.0 g | Ultra-low calories |
| Green Beans | 31 | 1.8 g | 2.7 g | 7.0 g | Balanced macro profile |
What sets the nutrition of hearts of palm apart is the protein-to-calorie ratio. At 28 calories with 2.5 grams of protein, they offer roughly 0.089 grams of protein per calorie—higher than asparagus (0.11, slightly better) but far ahead of celery (0.05) and comparable to artichokes (0.07). This ratio makes hearts of palm a strategic addition for anyone aiming to increase protein intake without adding substantial energy.
Potential Risks and Considerations
Hearts of palm are generally well tolerated, but a few considerations deserve attention before making them a dietary staple.
Important Considerations
- Sodium in canned varieties: Canned hearts of palm are often packed in brine containing significant sodium—sometimes exceeding 400 milligrams per serving. Always drain and rinse thoroughly to reduce sodium by 30–40%.
- Allergenicity is rare but possible: Reports of allergic reactions to hearts of palm are extremely limited, and the peach palm fruit has a long history of safe consumption in Latin American diets. However, anyone with known palm or coconut allergies should exercise initial caution.
- Sustainability concerns: Not all hearts of palm are harvested sustainably. Single-stem palm species die after harvest, contributing to deforestation. Look for products labeled as sourced from cultivated or multi-stem palm species.
- Digestive adjustment: A sudden large increase in fiber intake from any source may cause temporary bloating or gas. Introduce hearts of palm gradually if your diet is currently low in fiber.
Practical Tips for Maximizing the Nutrition of Hearts of Palm
Getting the most out of the nutrition of hearts of palm is as much about how you prepare and pair them as it is about the vegetable itself. These practical strategies will help you integrate hearts of palm into your meals while preserving their nutritional integrity.
- Always rinse canned hearts of palm. Draining and rinsing under cool running water for 30 seconds removes excess sodium without leaching water-soluble vitamins significantly.
- Choose jars over cans when possible. Glass jars often use a lighter brine and let you see the product quality before purchasing. Some brands pack hearts of palm in water with minimal salt.
- Use them raw when you can. Hearts of palm are fully cooked and ready to eat straight from the can or jar. Using them raw in salads preserves heat-sensitive B vitamins.
- Pair with a fat source. The fat-soluble vitamins present in your meal—especially if you serve hearts of palm alongside leafy greens—are better absorbed when consumed with healthy fats like olive oil, avocado, or nuts.
- Try hearts of palm pasta. Pre-cut hearts of palm linguine or angel hair offers a nutrient-dense alternative to grain-based pasta. A quick search for hearts of palm pasta reveals several convenient options that cook in minutes.
- Incorporate into meal prep. Sliced hearts of palm hold their texture well for days when stored in an airtight container, making them ideal for batch-prepped salads and grain bowls.
- Experiment with cooking methods. Briefly sautéing, grilling, or air-frying hearts of palm enhances their natural sweetness while retaining most minerals. Avoid prolonged boiling, which can leach water-soluble nutrients into the cooking water.
Common Mistakes When Buying and Using Hearts of Palm
Even health-conscious shoppers and home cooks can make missteps that reduce the nutritional benefit of hearts of palm. Avoid these common errors:
- Skipping the rinse. Pouring canned hearts of palm straight into a dish without rinsing loads the meal with unnecessary sodium—sometimes turning an otherwise heart-healthy ingredient into a high-sodium one.
- Assuming all brands are equal. Sodium content varies widely between brands. Some contain as little as 50 milligrams per serving, while others exceed 400 milligrams. Check the nutrition label before buying.
- Overcooking. Hearts of palm are already tender. Prolonged cooking turns them mushy and may degrade some B vitamins. A quick 2–3 minute sauté or brief warming is usually sufficient.
- Ignoring sustainability labels. Choosing hearts of palm without verifying the source can inadvertently support ecologically damaging harvesting practices. Look for products labeled as sustainably harvested or sourced from cultivated palms.
- Treating them only as a salad ingredient. Limiting hearts of palm to cold salads overlooks their versatility. They perform beautifully in stir-fries, soups, casseroles, tacos, and even as a stand-alone grilled side dish.
- Storing opened cans improperly. Once opened, canned hearts of palm should be transferred to a sealed container with fresh water and refrigerated. Storing them in the opened can may impart a metallic taste and reduce quality.
Evidence-Based Recommendations
Based on the nutritional profile and available evidence, here are core recommendations for incorporating hearts of palm into a health-focused diet:
- For weight management: Replace one starchy side dish per day with hearts of palm—either as a pasta alternative, salad base, or sautéed side. The caloric savings can reach 150–200 calories per meal compared to rice or wheat pasta.
- For plant-based eaters: Use hearts of palm as a complementary protein source alongside legumes, whole grains, or nuts to build complete amino acid profiles across meals.
- For heart health: Choose low-sodium or no-salt-added varieties and pair hearts of palm with potassium-rich foods like spinach, sweet potatoes, and avocado to support blood pressure regulation.
- For digestive health: Gradually increase intake to allow the gut microbiome to adapt to the additional fiber, aiming for 2–4 servings per week as a starting point.
- For blood sugar control: Substitute hearts of palm noodles for traditional pasta in favorite dishes. The reduction in digestible carbohydrates can meaningfully lower post-meal glycemic response.
- For general wellness: Rotate hearts of palm with other nutrient-dense vegetables such as artichokes, asparagus, and leafy greens to ensure a broad spectrum of phytonutrients and minerals across the week.
