Tattfoo Tan, a Malaysian-born artist who lives in Staten Island, New York, takes regular trips to the Union Square Greenmarket. After photographing his purchases, he started using Photoshop's eyedropper tool to extract 88 colors that would best represent 88 different fruits and vegetables. He called it the Nature Matching System.
If the 15 million pounds of artificial dyes approved for food use in the United Sates—some of which were derived from coal tar and petroleum—are being implicated in behavioral problems, especially for those kids already diagnosed with ADHD, should we eliminate foods containing added food coloring altogether?
Presumably, you'd have fewer kids bouncing off the walls. As early as the 1970s, Dr. Benjamin Feingold, whose organization has been lobbying the FDA to change its labeling rules, advanced this hypothesis. Forty years later, there's still no scientific consensus on the benefits of eliminating food coloring.
