Carrageenan (E407)
Definition
A thickener and stabilizer extracted from red seaweed, used to improve texture and prevent separation in dairy and plant-based products.
Why It Matters
While food-grade (undegraded) carrageenan is classified as safe by the FDA, research published in Environmental Health Perspectives shows it can trigger intestinal inflammation and may exacerbate inflammatory bowel conditions. Degraded carrageenan (poligeenan) is a recognized carcinogen. The Cornucopia Institute has petitioned for its removal from organic food standards.

Natural Flavors
CautionAccording to the FDA (21 CFR 101.22), 'natural flavor' is any flavoring derived from a plant or animal source — including fruits, vegetables, herbs, bark, roots, meat, seafood, poultry, eggs, or dairy — through heating, distillation, or fermentation. A single 'natural flavor' listing can contain dozens of individual chemical compounds, solvents, emulsifiers, and preservatives.
Maltodextrin
CautionA highly processed white powder made from corn, rice, potato, or wheat starch. Despite being classified as a complex carbohydrate, it is broken down so aggressively during processing that its glycemic index (GI 85-105) often exceeds that of table sugar (GI 65).
