Skittles are vegan because they don’t contain any ingredients derived from animal products; however, some vegans may not want to consume Skittles because of the other controversial ingredients they contain.
Skittles Ingredients
Contrary to what many people think, Skittles do not contain gelatin or any other animal based ingredients. However, Skittles sold in the U.S. did contain gelatin up until 2009, which is why many people still think they do today.
The ingredients in Skittles as of 2009 are:
Sugar, Corn Syrup, Hydrogenated Palm Kernel Oil, Apple Juice from Concentrate, Less than 2% Citric Acid, Dextrin, Modified Corn Starch, Natural and Artificial Flavors, Coloring (Includes Yellow 6 Lake, Red 40 Lake, Yellow 5 Lake, Blue 2 Lake, Yellow 5, Red 40, Yellow 6, Blue 1 Lake, Blue 1), Ascorbic Acid (Vitamin C).
Controversial Food Colorings
The chemicals used in Skittles to add coloring, including Red 40, Yellow 6, and Yellow 5 have been the subject of much controversy surrounding their alleged adverse health effects. While no conclusive evidence has been produced, many professional and independent researchers suspect their may be a link between these chemicals and certain illnesses, such as cancer.
