Carrageenan
The question

Is Carrageenan safe in salad dressing?

AvoidSalad dressing

Red seaweed-derived thickener. While "natural," research suggests it promotes intestinal inflammation and may be contaminated with degraded carrageenan (poligeenan), which is carcinogenic.

What the research flags

  • Promotes intestinal inflammation and increases intestinal permeability in animal and cell studies
  • Contamination with degraded carrageenan (poligeenan) — a definite carcinogen (IARC Group 2B for poligeenan)
  • National Organic Standards Board voted to remove it from certified organic foods (2012) — decision later reversed
  • Linked to worsening of IBD symptoms in some patients

Regulatory
EU removed degraded carrageenan from permitted food additives
