What nutrients are in hemp seeds?

Hemp seeds contain 161 kcal per 28g serving with 9.5g of protein providing all nine essential amino acids, 12.3g of healthy fats (including omega-3 and omega-6), and 1.2g of dietary fiber. According to USDA FoodData Central, hemp seeds provide approximately 210mg of magnesium (50% DV), 3.9mg of iron (22% DV), 3.1mg of zinc (28% DV), and 2.8mg of manganese (122% DV) per serving, making hemp seeds exceptionally rich in essential minerals compared to most plant-based foods.

What are the health benefits of hemp seeds?

Hemp seeds provide cardiovascular protection, muscle recovery support, hormonal balance, support for healthy inflammatory balance, and digestive health improvement through their unique combination of protein containing all essential amino acids, omega fatty acids, and mineral content.

1. Cardiovascular Health: The 2.6g of omega-3 ALA per 28g serving supports heart health by helping maintain healthy inflammatory responses and supporting lipid profiles, while arginine content promotes nitric oxide production for healthy blood vessel function.
2. Complete Amino Acid Profile: Hemp seeds provide all nine essential amino acids with 9.5g of protein per serving; however, lysine content is relatively lower compared to soy or pea protein, making hemp seeds complementary when combined with other protein sources in plant-based diets.
3. Supports Healthy Inflammatory Balance: The approximately 1:3 omega-3 to omega-6 ratio in hemp seeds provides a balanced fatty acid profile favorable for typical Western diets, with gamma-linolenic acid (GLA) content helping modulate inflammatory responses.
4. Mineral Support for Bone Health: With approximately 210mg of magnesium and 405mg of phosphorus per serving, hemp seeds support bone density and calcium metabolism, with magnesium also regulating over 300 enzymatic reactions in the body.
5. Hormonal Balance: The gamma-linolenic acid (GLA) content in hemp seeds helps regulate prostaglandin synthesis, potentially supporting reproductive health and reducing PMS symptoms.

For a detailed breakdown of healthy fats in various seeds, hemp seeds rank among the top sources of balanced omega fatty acids.

What types of hemp seed varieties exist?

Hemp seeds are available in two primary forms: hulled hemp seeds (hemp hearts) and whole hemp seeds with shells intact.

Hulled Hemp Seeds (Hemp Hearts): These are shelled seeds with the outer hull removed, appearing creamy white to light green. Hulled hemp seeds contain higher concentrations of protein (9.5g per 28g) and fat, with a softer texture ideal for direct consumption, smoothies, and baking.

Whole Hemp Seeds: These retain the crunchy outer shell, providing approximately 3g of fiber per 28g serving compared to 1.2g in hulled varieties. Whole hemp seeds offer a nutty crunch and higher fiber content but require more chewing and have slightly lower digestibility.

Hemp Seed Products: Hemp seeds are also processed into hemp protein powder (50-70% protein content), hemp seed oil (cold-pressed for omega-3 supplementation), and hemp seed additions to trail mixes for enhanced nutritional diversity.

How do you choose and store hemp seeds?

Select hemp seeds that appear uniform in color (creamy white for hulled varieties), have a fresh nutty aroma without rancid odors, and are packaged in opaque, sealed containers to protect the delicate omega-3 fatty acids from light and oxygen degradation.

Selection Tips:

• Choose organic, non-GMO certified hemp seeds to ensure pesticide-free cultivation
• Check packaging dates and select products within 3 months of processing
• Avoid seeds with moisture, discoloration, or off-smells indicating oxidation
• Prefer vacuum-sealed or nitrogen-flushed packaging for maximum freshness

Storage Guidelines:

1. Store unopened hemp seeds in a cool, dark pantry for up to 12 months
2. Refrigerate opened hemp seeds in airtight glass containers for 3-4 months
3. Freeze hemp seeds in freezer-safe containers for extended storage up to 12 months
4. Keep hemp seeds away from heat, light, and moisture to prevent rancidity
5. Always smell hemp seeds before use; discard if they develop a bitter or paint-like odor

Who should eat hemp seeds and who should avoid them?

Hemp seeds are beneficial for vegans seeking complete amino acid profiles, individuals with cardiovascular concerns requiring omega-3 supplementation, athletes needing muscle recovery support, and people supporting healthy inflammatory balance, while those with hemp allergies, individuals on anticoagulant medications, or people with digestive sensitivities should exercise caution.

Ideal Consumers:

• Plant-based dieters requiring protein sources with all 9 essential amino acids
• Individuals with magnesium deficiency or muscle cramps (approximately 210mg per serving)
• People managing cardiovascular risk factors (omega-3 for lipid profile support)
• Those supporting healthy inflammatory responses through dietary omega-3 intake
• Athletes and active individuals seeking digestible protein for recovery

Cautions and Contraindications:

• People with hemp or Cannabis family allergies may experience allergic reactions
• Individuals on anticoagulant medications should consult their clinician, as high-dose omega-3 fatty acids can interact with blood clotting pathways
• Those with digestive disorders may need to start with small amounts (1 teaspoon) due to fiber content
• Food-grade hulled hemp seeds are effectively THC-free; false positives on drug tests are unlikely but depend on manufacturing quality and potential cross-contamination during processing
• People with compromised immune systems should choose reputable brands with quality testing

What are interesting facts about hemp seeds?

• Hemp cultivation dates back over 10,000 years, with archaeological evidence showing hemp seed consumption in ancient China as early as 8000 BCE for both nutrition and medicinal purposes.
• Hemp seeds contain rare gamma-linolenic acid (GLA), an omega-6 fatty acid found in only a handful of food sources including evening primrose oil and borage oil, which supports prostaglandin production.
• The hemp plant is highly sustainable, often requiring less water than cotton, minimal pesticides, and improving soil health by returning nutrients during growth, making hemp seeds one of the most environmentally friendly protein sources.
• According to historical records, hemp seeds were used as emergency food during World War II rationing due to their complete nutritional profile and long storage stability.
• Hemp seeds contain higher levels of arginine than most nuts, with arginine serving as a precursor to nitric oxide, which helps relax blood vessels and supports healthy blood pressure levels.
