Hearts of Palm's Protein Content: Raw vs. Canned
Understanding the protein content of hearts of palm requires looking at its preparation. Canned and raw versions have slightly different nutritional profiles, mainly due to the canning process and the liquid they are packed in. A 100-gram serving of raw hearts of palm can contain about 2.7 to 4 grams of protein, a figure that is higher than many other common vegetables on a per-calorie basis. For instance, a cup of canned hearts of palm provides around 3.7 grams of protein. While this is not comparable to high-protein sources like meat or legumes, for a low-calorie vegetable, it is noteworthy.
The amino acid profile of hearts of palm is also significant, containing all nine essential amino acids. This makes it a more complete protein source than many other plant foods, supporting various bodily functions like tissue repair and synthesis. This aspect is especially beneficial for those on vegetarian or vegan diets who seek varied sources of complete protein.
