E143 Fast Green

What is E143 Fast Green?

E143, also known as Fast Green FCF, is a synthetic green dye often used in food products, cosmetics, and pharmaceuticals. It provides a bright green color and is added to items like jellies, ice cream, and salad dressings. This dye is valued for its stability in acidic environments and its strong coloring properties.

Why do I have an intolerance?

Fast Green intolerance may result from the synthetic nature of the dye. Individuals sensitive to artificial food additives might experience symptoms such as stomach cramps, headaches, or skin rashes. As with other artificial dyes, the immune system may recognize Fast Green as a foreign substance, triggering an adverse reaction.

What can I do about it?

If you suspect an intolerance to E143, eliminate foods and products that contain this dye. Reading ingredient lists carefully and choosing naturally colored foods will help avoid symptoms. Look for foods that use plant-based colorants, like matcha or parsley extract, as a safer alternative.
