NEW YORK (WABC) -- There are concerns that a new brand of peanut butter could make children too caffeinated.
"Steem Peanut Butter", just launched last year, with sales mostly online and at a few small shops in the Northeast. One serving contains 170 milligrams of caffeine.
Senator Charles Schumer says that is five times more caffeine than a single can of Coke.
The developers say the caffeine is released slowly because peanut butter takes longer to digest than coffee.
Senator Schumer says he wants the FDA to investigate.
