Caffeine is showing up in more and more snack foods and candy, and now the Food and Drug Administration is taking a closer look.
FOX News Radio's Jared Halpern reports from Washington:
Food companies are producing and marketing potato chips, and jelly beans with caffeine. Wrigley the latest company to unveil an Alert Energy Chewing Gum.
The FDA's Deputy Commissioner of Foods believes caffeine now deserves a closer inspection of safety concerns.
The FDA approved caffeine for colas in the 1950's, but now the agency warns proliferation of caffeine in foods has spread beyond anything the FDA envisioned.
A Wrigley spokesperson says the chewing gum is labeled for adult use only, adding millions of Americans consume caffeine responsibly and in moderation.
