Yes, you can eat hearts of palm raw. Fresh hearts of palm have a mild, slightly nutty flavor and a tender crunch that works well in salads, sliced into dips, or eaten straight. The catch is finding them fresh, since most hearts of palm sold worldwide come canned or jarred, already cooked and preserved during processing.
Why Fresh Hearts of Palm Are Hard to Find
Hearts of palm are the soft inner core of certain palm tree species, harvested from the growing tip of the trunk. Once cut, the exposed core begins to deteriorate quickly. Even in tropical countries where palms are cultivated, the vegetable is usually boiled and processed shortly after harvest because of how fast it spoils. This is why the canned version dominates grocery store shelves in the U.S. and Europe.
If you do find fresh hearts of palm at a specialty grocer or farmers market, refrigerate them immediately. They should be sealed tightly and used within a few days. Fresh hearts of palm are pale, cylindrical stalks wrapped in several layers of fibrous outer sheaths. To prepare them, you peel away those tough outer layers (typically two or three) until you reach the smooth, tender core inside. That core is the part you eat.
Raw vs. Canned: Key Differences
The nutritional profile of raw hearts of palm is impressive for such a mild-tasting vegetable. A 3.5-ounce (100-gram) raw serving contains just 36 calories, along with 4 grams of protein and 4 grams of fiber. It also delivers 38% of your daily potassium needs, putting it in the same league as bananas for this mineral.
One of the biggest practical differences between fresh and canned is sodium. Canned hearts of palm are packed in brine, which significantly raises their sodium content. If you’re watching your salt intake, fresh hearts of palm give you all the nutritional benefits without the added sodium. When using canned, draining and rinsing them helps reduce sodium somewhat, but it won’t eliminate the difference entirely.
How to Use Raw Hearts of Palm
Fresh hearts of palm have a texture somewhere between an artichoke heart and a water chestnut, with a clean, faintly sweet taste. Sliced thin, they’re a natural fit for salads, adding a satisfying crunch without overpowering other ingredients. You can also dice them into ceviche, shave them into ribbons with a vegetable peeler, or simply eat them in rounds with a squeeze of lemon.
Canned hearts of palm, while already cooked, are also commonly eaten without further cooking. People toss them into salads, pasta dishes, and grain bowls straight from the jar. So whether your “raw” question is about fresh or about eating canned hearts of palm cold, both are perfectly safe. The canned version has simply been precooked during the canning process, so it’s ready to eat as-is. You can also add either version to soups and stews if you prefer them warm.
Sustainability Worth Knowing About
Not all hearts of palm are harvested equally, and this matters if you care about where your food comes from. Traditional harvesting targets species like the juçara palm, native to Brazil’s Atlantic Forest. That palm dies after its heart is removed, and decades of demand have pushed the species toward endangerment.
The more sustainable option is the peach palm, which produces new shoots after harvesting and begins yielding hearts of palm just 18 months after planting. It can keep producing new shoots for about 10 years. In Brazil, peach palm cultivation has grown significantly as a way to take pressure off wild juçara and açaí palm populations. Many brands now label their products as sustainably sourced from cultivated peach palms, so look for that distinction when shopping. About 90% of Brazil’s palm heart production still comes from extractive harvesting of wild açaí and juçara palms, so choosing cultivated peach palm products makes a real difference.
Fiber and Digestive Benefits
Those 4 grams of fiber per 3.5-ounce serving are notable for a vegetable this low in calories. Fiber supports regular digestion by adding bulk to stool and feeding beneficial gut bacteria. For context, most adults need 25 to 30 grams of fiber daily, so a serving of hearts of palm covers roughly 13 to 16% of that goal. Pairing them with other vegetables in a salad can easily push a single meal’s fiber content into a meaningful range.
The high potassium content also makes hearts of palm useful for people managing blood pressure, since potassium helps counterbalance the effects of sodium. This is one more reason fresh hearts of palm (with no added salt from canning brine) are worth seeking out if you can find them.
