Hemp

Studies in people

• Benefit

  Vegetarian nutrition²

  Hemp seeds are rich in protein, essential fatty acids and minerals, making them a useful extra option in vegetarian diets.

• Open question

  Heart and blood sugar health⁴

  In adults, eating hemp products raised some blood fatty acids but did not change cholesterol, blood sugar, blood pressure or body fat.

• Benefit

  Hunger and blood sugar hormones⁵

  In people, a hemp-rich meal raised a gut hormone and lowered insulin and hunger hormone levels.

• No harm found

  Gut health after exercise⁶

  In cyclists, two weeks of hemp fiber bars did not change how leaky their guts were after hard riding.

Animal and lab studies only

• Benefit

  Antioxidant effects in the body¹¹

  In lab studies, hemp proteins showed antioxidant activity, but the authors say more research is needed.

• Benefit

  Gut inflammation¹²

  In animal studies, hemp seed eased gut inflammation and helped protect the gut lining in mice with colitis.

Study type not stated

• Benefit

  Nutritional value of seeds⁷

  Hemp seeds pack complete protein, healthy fats, and fiber, though scaling up supply and keeping quality steady remain hard.

• Benefit

  CBD health benefits⁸

  Scientists say hemp and CBD in food may help health, but more research is needed to confirm this.

• Benefit

  Seed and sprout nutrients⁹

  Hempseed provides protein, fats, minerals, vitamins and fiber, and hemp sprouts are rich in antioxidants.

• Benefit

  Pain and inflammation relief¹⁰

  Hemp contains CBD, which studies suggest may help with pain and swelling, but scientists still need more proof.

Single cases of misuse or overdose

One person or one incident, such as an accidental overdose or a mistake in a kitchen or factory. They are real, but a single case does not show what happens at normal amounts, so the signal does not count them.

• Child poisoning from a supplement³

  A preschool boy on hemp seed oil for three weeks got mild cannabinoid poisoning, with symptoms that cleared up in hospital.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted.
