Hemp protein is packed with benefits. Research shows that hempseeds have a nutty taste and can provide essential amino and fatty acids, along with other minerals, fibers, and vitamins. The risk of hemp protein side effects is low, but it’s also possible to have a hemp allergy. Read to learn more about the effects of hemp protein. Hemp Seed Allergy For people with Cannabis sativa allergies, adding hemp protein to their diet can be dangerous. Researchers note that allergic reactions to hemp have been reported. Although some foods are known for being common allergens, such as nuts and shellfish, any food can potentially cause an allergic reaction in a susceptible person. According to the Mayo Clinic , common food allergy symptoms include: Wheezing Nasal congestion Difficulty breathing Tingling or itchy mouth Hives Itching Eczema Swelling of lips, tongue, throat, face, or other areas of the body Abdominal pain Diarrhea Nausea and vomiting Dizziness, lightheadedness, or fainting Research shows that a hemp allergy, specifically, can cause severe anaphylaxis, which can be life-threatening. According to StatPearls , signs of anaphylaxis include: Shortness of breath Wheezing Stridor (a harsh whistling sound when air flows through the upper airways) Low blood oxygen levels Persistent throat clearing or coughing Hives Painful cramps or vomiting that are persistent If you develop any symptoms of anaphylaxis after eating hemp protein powder, seek emergency medical attention immediately. Excess Fiber Side Effects Fiber is crucial in a healthy diet, but according to the Cleveland Clinic , too much of it at one time can cause bloating, cramping, gas, and constipation. And this includes hemp fiber. Additionally, if you haven’t previously been eating a lot of fiber, even a single serving could cause digestive distress if your body simply isn’t used to it. To avoid these unwanted effects, increase your intake gradually over time and stick to a single serving, unless you know your body is able to handle more. Excess Mineral Intakes Research shows that hemp seeds are an especially rich source of the minerals manganese and iron. As such, there is a risk of side effects and toxicity when consumed in large amounts. For example, the National Institutes of Health warn that high-dose iron supplements can also cause gastrointestinal side effects. But the risk of excess iron side effects from protein powder is much lower than from iron pills, because it is ingested along with other macronutrients that help buffer its impact on the gastrointestinal system. Dangers of Hemp Supplements All protein powders are considered supplements, and the U.S. Food and Drug Administration doesn’t regulate them in the same way as food. Because of this, you can’t always trust that what’s on the label is actually in the supplement, warns Harvard Health Publishing . A supplement may contain added sugars, artificial ingredients, or other allergenic ingredients or contaminants that are not easily detectable by the consumer.
