Study type not stated

• Benefit

  Inflammation and metabolism⁹

  Pine nuts contain pinolenic acid, which studies suggest may help calm inflammation and affect how the body handles fats.

Allergies and intolerances

These are about people with an allergy, an intolerance or coeliac disease. The signal is about the ingredient itself, and these are about the person eating it, so the signal does not count them.

• Food allergy symptoms²

  Two people had allergic reactions after eating pine nuts, with skin tests showing a reaction.

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.

• Severe allergic reaction³

  A person had a serious allergic reaction right after eating pine nuts and needed emergency care.

• Food allergy reaction⁵

  A woman had an allergic reaction to pine nuts, even though pine pollen never made her sneeze.

• Severe allergic reaction to food⁷

  Two young girls had a severe allergic reaction to pine nuts, and a protein in them may be the cause.

• Allergic reaction to food⁸

  A woman had a severe allergic reaction after eating pine nuts from her parrot's food.

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.
