Hemp Seeds (Hemp Hearts) Guide: Protein, Healthy Fats and How to Eat Them

Hemp seeds come from the hemp plant, a variety of Cannabis grown for food and fiber that does not have the intoxicating effect of marijuana. The part most people eat is the soft inner kernel, called hemp hearts. They have a gentle, nutty, slightly grassy flavor and a tender texture, a bit like a cross between pine nuts and sunflower seeds.

What makes hemp special?

Hemp hearts are one of the more protein-rich seeds. Three tablespoons (about 30 grams) give roughly 9 to 10 grams of protein, along with healthy unsaturated fats, some iron and a useful amount of magnesium and zinc. Hemp contains the plant omega-3 fat ALA and also an omega-6 fat in a balance many nutrition writers describe as favorable. Hemp hearts have much less fiber than chia or flax, because the fibrous hull has been removed.

Hulled or whole?

Hemp hearts are hulled seeds, soft and ready to eat. Whole hemp seeds still have their crunchy shell. The shell is edible and adds fiber, but it is chewy and a little gritty. Most people prefer hearts for everyday use, and whole seeds are better ground into a powder or added to baking.

Easy ways to use hemp hearts

Sprinkle them straight onto salads, soups, avocado toast or roasted vegetables. Stir them into oatmeal and yogurt, or blend three tablespoons into a smoothie for extra body. Mix them into homemade energy balls, granola bars or veggie burgers. You can even blend hemp hearts with water to make a quick creamy seed milk, then strain it or leave it as it is. They do not need soaking or cooking.

Storage matters

Hemp is high in delicate polyunsaturated fats, so it can go rancid more quickly than some other seeds. Keep opened packs tightly sealed in the fridge, and use them within a few months. If they smell fishy, bitter or sharp, throw them out.

How much should you eat?

One to three tablespoons a day fits easily into most diets. Hemp hearts are calorie-dense, at roughly 170 calories for three tablespoons, so they work best as a topping or boost rather than something eaten by the cupful.

Who should check first?

Hemp foods contain only trace amounts of THC, but if you are drug tested for work or sport, it is sensible to ask about hemp products first, as rare positive results have been reported. People on blood thinners or medicines for blood pressure should check with their doctor, because hemp's fats may add to those effects. Anyone with a seed allergy, kidney disease or who is pregnant or breastfeeding should also ask their healthcare provider before making hemp a regular food.

Hemp is a good example of why variety matters: used alongside chia, flax and pumpkin seeds, it helps you cover a wider range of nutrients.
