Artificial Colours Part 2

The food industry has a long history with food dyes, both synthetic and nature-derived. They are widely used because humans eat with their eyes. It’s important, however, to question and evaluate the safety of these synthetic food dyes. There are examples of food dyes widely used for years, then banned due to negative health effects, such as Orange 1. Today TellSpec is sharing the research on six synthetic food dyes possibly present in your food; with the exception of Orange 1, these are dyes that are currently approved as safe for use in noted nations.
