To enhance the colors of foods, they may be dyed. Methods vary—from chemicals and petroleum-based ingredients to animal products and even plants. Common artificial dyes include Red 40, Yellow 5, and Yellow 6, and one of the most widely used red food colorings come from crushed cochineal beetles.

Artificial Food Colors and Our Health

A randomized, double-blind, placebo-controlled food challenge published in the most prestigious medical journal in the world found that consumption of artificial colors increased impulsivity, inattentiveness, and hyperactivity among young children, and there are cancer concerns for individuals of all ages. In fact, Red 1 was banned in 1961 in the United States and Red 2 in 1976, for instance. Red 3, which may be found in products like sausage and maraschino cherries, has been shown to influence kids’ behavior, interfere with thyroid function, and cause DNA damage in human liver cells in vitro, comparable to the damaged caused by a chemotherapy drug whose purpose is to break down DNA, yet it remains in our food supply. Industry pressure looms large despite repeated calls to better regulate or outright ban artificial colors.

Dyeing Foods with Plants

Should you want to make your cherry popsicles red, how about adding some cherries? Spinach and mint can make food green, and beets turn dishes a beautiful pinkish-red. Raspberries, too, can offer a pinkish hue. Turmeric or saffron, two spices, aren’t only health-promoting, but they can add a yellow color to dishes.

What About Annatto?

Annatto is a food dye derived from the seeds of the achiote tree. Although there have been case reports of severe allergic reactions and irritable bowel syndrome-type symptoms, there haven’t been any comprehensive studies performed on humans to date.
