Yellow 5 or Tartrazine is is a lemon yellow dye used mostly as a food colorant. Also known as E102.
There are many food products in the market using Tartrazine as a yellow colorant, also can be mixed with other substance to produce other color shades as green or brown.

Yellow 5 has been related to different health issues as:
1. Allergies.
Allergic reaction have been reported in people consuming Tartrazine. The reaction can present as asthma, urticaria, or rhinitis. This occurs mostly in aspirin sensitive patients.
2. Hyperactivity:
"In one study of 76 children diagnosed as hyperactive, the food color Tartrazine combined with the food preservative benzoate caused abnormal reactions in 79 % of the group" (1). Tartrazine also has shown to increase excretion of zinc and therefore deterioration in behavior.
3. Zinc deficiency:
Zinc, an essential trace mineral, is required for the metabolism of protein, carbohydrate, fat and alcohol. Zinc is also needed for a correct wound healing, sense of taste and smell, immune system function, bone strength, thyroid function, blood clotting, cognitive functions, prenatal development, and sperm production. Even a mild deficiency can produce a wide range of physical and mental problems.
Even though many companies have decided to remove this coloring from their product, Yellow 5 dye still listed as a permitted food coloring in Canada. https://www.canada.ca/en/health-canada/services/food-nutrition/food-safety/food-additives/lists-permitted/3-colouring-agents.html.
It can be named on the list of ingredients under its name or under "color". Tartrazine is one of many food colorants and/or additives that are under study. It is good practice to review the ingredients on the packages before purchasing. After all our kids are the most affected by this.
