Pectin prebiotics in peach allergic patients

What it found

In people with peach allergy, two pectins increased allergen tolerance in more than 50% of patients and changed gut bacteria and immune markers.

The authors say pectin treatment is a promising option for LTP allergy.

What they found

Studies in people

Allergen tolerance

Both pectins led to a significant clinical increase in allergen tolerance in more than 50% of patients.

Immune response

Both pectin groups showed a drop in various inflammatory cytokines compared to placebo.

Gut bacteria changes

Citrus pectin increased Bacteroides_H and Roseburia intestinalis. Apple pectin increased Bifidobacterium, Succinivibrio, and Faecalibacterium prausnitzii.

Short-chain fatty acids

Both pectins reduced levels of branched short-chain fatty acids compared to placebo.

Bile acids

Pectin supplementation changed fecal levels of microbial-derived secondary bile acids.

What the authors conclude

“This study suggests that pectin treatment is a promising and safe option for LTP allergy.”

Also in their conclusions

  • They suggest that pectin treatment is a promising and safe option for LTP allergy.

How it was done

There is great interest in using pectins as prebiotic treatment for food allergy.

Peach allergic patients sensitised to lipid transfer proteins were given low methoxyl citrus pectin, high methoxyl apple pectin, or a placebo. The study looked at immune response, gut bacteria, and microbial products including short-chain fatty acids and bile acids.

What it can’t tell you

  • We summarised it from the abstract only.
  • The study only looked at peach allergic patients sensitised to lipid transfer proteins, so the results may not apply to other allergies or other groups.
  • It does not show whether these changes last beyond the study period.
