Ban the Use of E171 (Titanium Dioxide) in Food Products in the UK

Background
These risks are especially troubling because E171 provides no nutritional value and is used only for colouring and whitening foods such as sweets, chewing gum, and sauces.
Given the uncertainty surrounding its long-term health effects, we urge the Government to take a precautionary approach and remove this additive from all food products sold in the UK.
