Organic Hemp Hearts

Also known as: Hemp hearts, Shelled hemp seeds, Hempseed kernels, Hemp seeds, Cannabis sativa L.

Overview

Hemp hearts, derived from *Cannabis sativa* L., are dehulled hemp seeds valued for their nutritional profile. They are rich in protein (25-30%), polyunsaturated fatty acids (PUFAs, 30-35%), and fiber. Hemp hearts are utilized as a functional food and nutritional supplement, primarily for cardiovascular support, protein supplementation, and dietary mineral enrichment. They contain all essential amino acids and boast an optimal 3:1 omega-6 to omega-3 fatty acid ratio, along with γ-linolenic acid (GLA). Research on hemp hearts is still emerging, with limited long-term randomized controlled trials (RCTs). Current evidence suggests moderate cardiovascular benefits and preliminary metabolic effects. They are available in various forms, most commonly as the raw, dehulled seed.

Benefits

Hemp hearts offer several potential health benefits. They may support cardiovascular health by reducing platelet aggregation, as indicated in animal studies. Preliminary human trials suggest potential blood pressure management benefits from hemp protein. Hempseed consumption has shown promise in improving intestinal permeability and glucose homeostasis in animal models. Furthermore, hemp hearts are a rich source of essential nutrients, with a 50g serving providing over 100% of the Recommended Daily Intake (RDI) for vitamin E and 50-100% of the RDI for magnesium and zinc. However, more extensive human clinical trials are needed to confirm these benefits.

How it works

The mechanism of action of hemp hearts involves several pathways. Their high PUFA content increases plasma ALA and LA concentrations, influencing eicosanoid production. Hemp hearts can modulate the endocannabinoid system through N-acylethanolamines, affecting CB1/CB2 receptor activity. Additionally, bioactive peptides from hemp protein hydrolysates may inhibit ACE enzymes, potentially contributing to blood pressure regulation. Hempseed protein is highly digestible, with a digestibility rate of 91-98%, facilitating efficient nutrient absorption.

Side effects

Hemp hearts are generally recognized as safe (GRAS) at food-level doses. Common side effects include mild gastrointestinal discomfort at intakes exceeding 50g per day. There is a theoretical risk of bleeding due to the antiplatelet effects of hempseed, warranting caution for individuals on anticoagulant medications. Hemp hearts may have additive effects with anticoagulants, increasing the risk of bleeding. It is advisable to discontinue hemp heart consumption two weeks prior to any surgical procedures. Individuals with cannabis allergies may experience cross-reactivity.

Dosage

The minimum effective dose of hemp hearts is around 15g per day to realize protein and fatty acid benefits. Optimal dosages, based on human trials, range from 25-30g per day. It is not recommended to exceed 50g per day due to limited safety data at higher doses. Hemp hearts should be consumed with meals to enhance the absorption of fat-soluble nutrients. While no strict upper limit has been established, exceeding recommended dosages may increase the risk of gastrointestinal discomfort.

FAQs

What is the THC content of hemp hearts?

Hemp hearts from compliant products contain less than 0.3% THC, which is considered non-psychoactive and will not produce any psychoactive effects.

Are hemp hearts allergenic?

Hemp hearts have low allergenicity, but there is a possibility of cross-reactivity for individuals with existing cannabis allergies. Those with known allergies should exercise caution.

Are hemp hearts sustainable?

Sustainability varies. Look for verification through certifications. Organic certification does not automatically guarantee sustainability, so check for broader environmental practices.

How long does it take to see results from consuming hemp hearts?

Acute changes in fatty acid levels can occur within hours of consumption. However, noticeable metabolic effects may require consistent intake for 8 weeks or longer.

Research Sources

https://pmc.ncbi.nlm.nih.gov/articles/PMC7891210/ – This is a protocol for an ongoing parallel-group trial (n=35) investigating the effects of 25g of hemp protein versus casein on blood pressure and endothelial function. The study aims to assess the potential cardiovascular benefits of hemp protein supplementation in humans.
https://pmc.ncbi.nlm.nih.gov/articles/PMC2868018/ – This rodent study investigated the effects of dietary hempseed intake (5-10%) over 12 weeks. The findings indicated a dose-dependent increase in PUFAs and a reduction in platelet aggregation (p<0.05), suggesting potential cardiovascular benefits. However, the results need to be translated to human studies to confirm these effects.
https://www.frontiersin.org/journals/nutrition/articles/10.3389/fnut.2022.1039180/full – This metabolic study examined the impact of hempseed supplementation in mice fed a high-fat, high-sugar (HFHS) diet for 8 weeks. The results showed improvements in gut permeability (p<0.05) and glucose homeostasis. This preclinical model suggests potential metabolic benefits of hempseed, but further research is needed to validate these findings in humans.
https://www.mdpi.com/1420-3049/29/9/2097 – This review article discusses the nutritional and health benefits of hemp seeds, highlighting their rich content of protein, essential fatty acids, and minerals. It summarizes the current evidence supporting the use of hemp seeds for various health conditions, including cardiovascular disease and metabolic disorders, while also acknowledging the need for more human clinical trials to confirm these benefits.
https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2022.882455/full – This study investigates the impact of hempseed on intestinal permeability and immune response in mice. The results suggest that hempseed supplementation can improve gut barrier function and modulate the immune system, potentially contributing to the prevention and treatment of inflammatory bowel diseases. However, these findings are based on a preclinical model and require further validation in human studies.
