A serving of hemp heart (3 tablespoons) has 166 calories but just 2.6 grams of carbohydrates. Nearly half of the carbs (about 1.2 grams) come from fiber. Only a half gram of carbs come from sugar and the rest comes from starch.
Hemp hearts are a low glycemic food with the glycemic load of a single 3-tablespoon serving estimated to be 0. A serving of 3 tablespoons has almost 15 grams of fat, of which 1.4 grams are saturated, 1.6 grams are monounsaturated, and 11.4 grams are polyunsaturated (omega-3 and omega-6 fatty acids). That’s more of the good fats than you’ll find in a similar serving of chia or flax seeds. Since hemp hearts are plant-based, they are also cholesterol-free. These little seeds pack a huge plant-based protein punch. A serving of 3 tablespoons has nearly 10 grams of protein, about double what you’ll find in a similar serving of flax seeds or chia seeds (about 5 grams each). Hemp seeds also contain all nine essential amino acids, and they are well digested, especially for a plant-based protein.
In general, animal sources such as eggs, milk, and whey have a protein digestibility-corrected amino acid score (PDCAA) of 1.00, which means they’re well digested. Soy leads the plant category with a score close to 1.00, followed by beans, pulses, and legumes (score of 0.6 to 0.7), and grains and nuts (0.4 to 0.5). Not only are hemp hearts loaded with healthy fats and proteins, but they’re also packed with nutrients. Hemp is an excellent source of magnesium, providing about 210mg or about 50% of your daily needs. A serving of seeds also has 13% of the daily iron requirements for adults (2.4mg). Hemp hearts are also a good source of zinc, providing about 3mg per serving or about 20% of your daily needs. By including hemp seeds in your diet, you may take advantage of certain health benefits. Many research studies investigating hemp benefits have been performed on animals. Like other seeds (and nuts), hemp seeds are heart-healthy. Studies have shown that they are high in both omega-3 fatty and omega-6 fatty acids. A healthy omega-3 to omega-6 intake is crucial for the prevention or reduction of many diseases, including cardiovascular disease. Authors of one research review concluded that there is enough evidence to support the hypothesis that hemp seeds have the potential to beneficially influence heart disease, but they added that more research is needed. You'll get a healthy dose of magnesium when consuming hemp seeds. Magnesium is needed by the body for maintaining healthy blood sugar levels. According to the National Institutes of Health, magnesium helps the body break down sugars and might help reduce the risk of insulin resistance—a condition that can lead to diabetes. Magnesium also helps your body to build stronger bones. The NIH reports that people with higher intakes of magnesium have a higher bone mineral density, which is important in reducing the risk of bone fractures and osteoporosis. And studies have shown that a proper level of magnesium in the body is important for maintaining healthy bones. Hemp seeds may provide some relief to those with constipation due to the fiber they provide. Researchers have found that increasing your fiber intake helps to increase stool frequency in patients with constipation. Preliminary research has also found that hemp seeds may help with constipation. One animal study found that consuming hemp seed soft capsules helped relieve constipation compared to the control group. However, more research needs to be conducted to understand the full benefit in humans. Another recent, preliminary animal study was conducted on the potential benefit hemp seeds might have on issues with memory and neuroinflammation. Researchers found that the hemp seed extract prevented the learning and spatial memory damage from inflammation and improved damage from the induced inflammation in the hippocampus. More studies need to be conducted to see if this benefit extends to humans.
Allergic reactions to Cannabis sativa have been reported, although many studies investigate the part of the plant used for marijuana use (not hemp seeds).
There have been reports of sore throat, nasal congestion, rhinitis, pharyngitis, wheezing, and other problems including anaphylactic responses. There have also been reports of hemp workers involved in processing hemp fibers at a textile mill showing a significantly higher prevalence of chronic respiratory symptoms. Recent reports of allergy to hemp seed are lacking. But at least one older study was published indicating that the condition is possible. When consumed as a food, hemp seed is generally recognized as safe (GRAS) by the FDA.
