Why Sodium Nitrite (E250) is More Than Just a Preservative

Sodium nitrite is a common preservative used in processed meats to prevent bacterial growth and maintain colour, but it carries significant metabolic risks. This article explores how E250 converts into carcinogenic nitrosamines and the implications for long-term health.

Carrageenan (E407): The Seaweed Derivative Linked to Gut Inflammation

Carrageenan is a common thickening agent derived from red seaweed, found in everything from almond milk to ice cream. Despite its 'natural' origins, evidence suggests it may trigger significant intestinal inflammation and disrupt gut barrier function.

Aspartame (E951) and the Excitotoxicity Debate

Aspartame is one of the world's most widely used artificial sweeteners, but its impact on brain health and metabolic function remains highly controversial. This article examines the science behind excitotoxicity and the recent WHO classification of E951.
