Hemp hearts are one of the most versatile seeds you can keep in your kitchen. These small, soft, cream-colored kernels (hemp seeds with the crunchy outer shell removed) have a mild, nutty flavor that blends into almost anything. With nearly 10 grams of protein and 15 grams of healthy fats in just three tablespoons, they pack serious nutrition into a tiny serving. Here’s how to actually use them.
Eat Them Straight or Sprinkle Them On
The simplest way to use hemp hearts is to treat them like a topping. Their soft texture and subtle nuttiness work well scattered over oatmeal, yogurt, smoothie bowls, or avocado toast. Unlike flax seeds, which need to be ground for your body to access their nutrients, hemp hearts are ready to eat as-is. Toss a few tablespoons onto a salad for a protein boost, stir them into overnight oats, or mix them into granola. They’re mild enough that they won’t overpower other flavors.
Blend Them Into Smoothies and Sauces
Hemp hearts dissolve beautifully when blended, making them a natural protein add-in for smoothies. Three tablespoons give you roughly the same protein as a hard-boiled egg. Blend them with banana, berries, and your milk of choice for a filling breakfast drink.
You can also blend hemp hearts with water to make a quick plant-based milk (about a quarter cup of seeds to one cup of water, strained or not). For something richer, blend them into creamy salad dressings, pesto, or dipping sauces. They work especially well as a base for dairy-free “parmesan” when pulsed with nutritional yeast, garlic powder, and salt.
Use Them in Baking and Cooking
Hemp hearts hold up to moderate heat. Research on roasted hemp seeds found that roasting at 140 to 160°C (roughly 285 to 320°F) for up to 35 minutes kept the fats well within safe oxidation limits. Roasting at 180°C (356°F) stayed safe for about 15 minutes. In parts of eastern Turkey, roasted hemp seeds are a traditional snack food.
This means you can fold hemp hearts into muffin batter, pancake mix, energy balls, or homemade bread without worrying about destroying their nutritional value, as long as you’re not blasting them at high heat for a long time. They add a subtle crunch to cookies and work well pressed into the crust of baked fish or chicken. For no-bake options, stir them into energy bites made with oats, nut butter, and honey.
Why They’re Worth Adding to Your Diet
Hemp hearts stand out nutritionally compared to other popular seeds. A two-tablespoon serving has about 7 grams of protein, compared to roughly 3 grams in the same amount of chia or flax seeds. They contain all nine essential amino acids, though lysine is present in lower amounts relative to the others. They’re lower in fiber than chia (8 grams per two tablespoons) or flax (5 grams), which is actually an advantage if high-fiber seeds tend to upset your stomach.
Most of the fat in hemp hearts is polyunsaturated, with a 2.5:1 ratio of omega-6 to omega-3 fatty acids. That ratio is considered favorable for heart health. Hemp hearts are also notably high in arginine, an amino acid that helps your body produce nitric oxide, a molecule that relaxes blood vessels and supports healthy blood pressure.
A clinical study on patients with eczema found that dietary hempseed oil significantly improved skin dryness and itchiness, likely because of its balanced supply of omega-3, omega-6, and gamma-linolenic acid (a less common fatty acid with anti-inflammatory properties). Participants also reduced their use of skin medication during the study period.
Storage Tips to Prevent Rancidity
Hemp hearts are high in delicate polyunsaturated fats, which makes them prone to going rancid when exposed to heat, light, and air. An unopened bag stored in a cool, dark place will last for months, but once you open the package, transfer the seeds to an airtight container and keep them in the refrigerator. For the longest shelf life, store them in the freezer, where they’ll stay fresh for up to a year. Research on hempseed oil found that refrigerated, dark storage provided far better protection against oxidation than room-temperature storage in clear containers.
Give your hemp hearts a sniff before using them. Fresh ones smell mildly nutty. If they smell sharp, bitter, or like oil paint, they’ve oxidized and should be tossed.
A Note on Drug Testing
Hemp hearts come from the same plant species as marijuana but contain only trace amounts of THC. In one study, volunteers who ate hemp seed food products produced urine specimens that initially screened positive on a standard marijuana immunoassay test, particularly at lower cutoff thresholds. However, when those same specimens were tested with the more precise method used to confirm positive results (gas chromatography), none met the reporting criteria for marijuana. The risk is low, but if you face regular drug screening, it’s worth knowing that eating large quantities of hemp products could potentially trigger an initial screening flag, even though confirmatory testing should clear it.
