Ann Louise Gittleman, in her book "Radical Metabolism," states that hemp seeds are a complete protein, providing all essential amino acids, and that a 30-gram serving (2 to 3 tablespoons) contains 11 grams of protein [4]. The book also notes that the fiber in hemp seeds is mostly in the hull, so hulled seeds, or hemp hearts, have relatively little fiber [4].
Angela Liddon, in" The Oh She Glows Cookbook," writes that three tablespoons of hulled hemp seeds contain 10 grams of protein and provide an ideal ratio of omega-6 to omega-3 fatty acids of 4:1 [6]. This ratio, according to Liddon, helps reduce inflammation in the body [6].
Hemp hearts are also a source of minerals including calcium, magnesium, iron, manganese, phosphorous, and potassium, according to Gittleman [4]. These seeds are considered a nutrient-dense food that can be added to smoothies, salads, and other dishes [6].
Hemp hearts are noted for their protein content and digestibility. Gittleman states that hemp seeds have protein "equal to beef or lamb but in a more digestible, bioavailable form" [4]. Unlike many plant proteins, hemp contains all nine essential amino acids, making it a complete protein, according to Liddon [6].
In comparison to other seeds such as chia and flax, hemp hearts provide more protein per serving. A news report on NaturalNews.com reviewing six types of seeds listed hemp among those recommended for their nutrient density, including protein and healthy fats [7]. The same report advised that because seeds are often high in fiber, it is best to drink plenty of water when consuming them [7].
Nutrition experts cited in another article stated that seeds are a source of fiber, healthy fats, essential amino acids and antioxidants, and that they support digestion and cardiovascular function [9]. Hemp hearts, being hulled, contain less fiber than whole seeds, but their protein content remains substantial, as noted by Gittleman [4].
The fatty acid composition of hemp hearts is a focus of research. Liddon reports that the ratio of omega-6 to omega-3 fatty acids in hemp seeds is 4:1, which she states helps reduce inflammation [6]. Eric Helms, in his book "The Juice Generation," describes hemp seeds as "one of the most well-rounded nutritional profiles of any plant food" and notes they are low in allergens and easily digestible [5].
General cardiovascular benefits associated with seeds are cited in recent reports. A NaturalNews.com article on seed health benefits stated that seeds, including hemp, "support cardiovascular function" [9].
Another report mentioned that hemp seeds "boost brain health and fight inflammation," attributes linked to their omega-3 content [8]. The fatty acids in hemp hearts are primarily polyunsaturated, which contributes to their reported anti-inflammatory effects [8].
Several accounts indicate potential benefits of hemp hearts for skin health. A NaturalNews.com article describes hemp seeds as "nature's skin superfood," citing an example of a woman who experienced reduced acne and redness after adding hemp seeds to her diet [3]. The same article highlights the anti-inflammatory and nutrient-rich properties of hemp seeds [3].
For digestion, while hulled hemp hearts contain less fiber than whole seeds, the fiber present in whole hemp seeds is known to aid digestion, according to Gittleman [4]. The mineral content in hemp hearts, including magnesium and zinc, may support immune function, as noted in various nutritional profiles [4, 1]
Hemp seeds offer antioxidant properties [1]. A recent article on hemp seeds as a superfood indicates they are "packed with plant-based protein, essential fatty acids, fiber and minerals" and that they support overall wellness without psychoactive effects [8].
Available evidence from multiple sources positions hemp hearts as a nutrient-dense food. They provide complete protein, a favorable fatty acid profile, and essential minerals. Authors such as Gittleman and Liddon emphasize their versatility and ease of incorporation into a balanced diet [4, 6, 1].
While reports support benefits for skin health, inflammation, and cardiovascular function, the provided sources do not include long-term human clinical trials. Consumers seeking to improve their nutrient intake may consider hemp hearts as a complementary food. Further research is needed to confirm specific health outcomes in broader populations.
