A critical review of the food colourants effects on Human Health and Environment

Food colour is a common food additive. Colour is essential for food which enhances the specific appearance of the food product and freshness. Hence, the use of artificial food colourants has increased tremendously during the past decades. Studies have reported that usage of synthetic food colouring in food products leads to severe health issues. The continuous use of synthetic food colourants causes behavioural changes like attention deficit, hyperactivity disorder in children and allergic reactions. Several researchers have reported that food-borne diseases are mainly caused by non-permitted colours. Synthetic food colours not only affect individuals, but They are also a potential cause of water contamination and much more environmental effects. Taking this into account, this study reviews the effect of synthetic colourants on humans and environment.
