Pectin

Studies in people

• Benefit

  Fiber and gut bacteria²

  Pectin, a fiber, feeds gut bacteria and may help digestion, immunity and cholesterol, though scientists are still working out the details.

• No harm found

  Gut bacteria and digestion³

  Pectin is fermented by gut bacteria rather than absorbed whole, and human studies found no bad effects.

• Benefit

  Peach allergy tolerance⁴

  In people with peach allergy, pectin increased how much peach they could handle.

• Open question

  Cholesterol levels⁵

  Eating citrus pectin with meals lowered cholesterol in nine people, though it also increased fat passed in stool.

Animal and lab studies only

• Benefit

  Liver damage from alcohol¹⁰

  In animal studies, pectin eased liver fat and inflammation from alcohol, but no human studies exist yet.

• Open question

  Gut barrier and immunity¹¹

  In lab studies, calcium made low and medium DM pectins block TLR2 less, but barely changed high DM pectin.

• Benefit

  Gut barrier and pancreas inflammation¹²

  In animal studies, okra pectin lessened pancreas inflammation and helped keep the gut lining intact.

• No harm found

  Tooth enamel erosion¹³

  In lab studies on human tooth enamel, pectin did not significantly reduce enamel softening from citric acid solutions.

• Benefit

  Gut inflammation¹⁵

  In mice, pectin stopped gut inflammation by blocking a body receptor, not by feeding gut bacteria.

• Benefit

  Gut cell growth¹⁶

  In lab studies, pectin from persimmon made gut cells grow faster, and its sugar branches seemed to matter.

Study type not stated

• Benefit

  Gut health and blood sugar⁶

  Pectin is a fibre that gut bacteria break down into substances that may help gut health and blood sugar.

• Benefit

  Blood sugar after meals⁷

  Pectin in food can slow starch digestion and help flatten the rise in blood sugar after eating.

• Benefit

  Immune and anti-inflammatory benefits⁸

  RG-I pectin, found in foods like potato, sugar beet and okra, may support the immune system and fight inflammation, obesity and cancer.

• Benefit

  Blood fat levels⁹

  Hawthorn pectin is a fruit substance that may lower the risk of high blood fats.

How it’s made and used

• Fat digestion¹⁴

  In lab studies, emulsions with more citrus pectin broke down fat more slowly than those with less.

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.
