I spent a few weeks on social media posting about artificial food colorings and why you should avoid them. I've compiled the posts together for you here!
RED 40 & RED 3
First up is the big guy, RED 40 or RED 3. It goes by other names, but just remember RED. This one has been specifically labeled as a known carcinogen, linked to infertility and ADHD in kids and is a hormone disruptor. What's alarming is how many products that might be on your shelves it is found in.
Here are some:
Cereals: Trix, Fruity Pebbles, Fruity Cheerios to name some.
Condiments: pickled items, some BBQ sauce, cherry pie fillings
CANDY: Skittles, M&M's, Jelly Beans, Starburts, among others...
Drugs: Children's Motrin, Flinstones chewable, many many many kids chewables....
Drinks: Gatorade, Powerade, Kool-Aid and most recently seen for all my fitness girls...BCAA powders, specifically XTEND. 
Cosmetics: eye shadow, lipstick, nail polish...
BLUE 1 & 2
BLUE 1 & 2 also known as Brilliant Blue and Indigo Blue. Sounds like paint colors to me. These 2 dyes have been linked to gastrointestinal symptoms, ADHD, asthma and allergies. There are MANY skin care products that have these blues in them which we can't ignore because the dyes are now absorbed in through our skin. Here are some products that contain the blues....but the real lesson here is to READ LABELS!
Cereals: Apple Jacks, Fruity Pebbles, Trix,
Condiments: gum
CANDY: Jelly beans, Starbursts, Jolly Ranchers, Skittles, Nerds, Gummy Bears...ANYTHING BLUE.
Drinks: Grape Drinks (Fanta), Hawaiian Punch

Skin Care/Cosmetics: there are over 900 cosmetic products that contain this dye. Oh em gee.
YELLOW 5 & 6
Lastly, YELLOW 5 and 6, also known as TARTRAZINE which is derived from coal tar is the 2nd most popular food dye. In Europe, there is a warning label on products that contain this and other artificial dyes. C'mon U.S.! This is another one of the most common dyes and is also a known to cause cancer, cause asthma, cause mutations and decreased sperm count in men. Did you know how many foods contain this yellow color? Here are some:
