Popcorn was found to have a high level of concentrated antioxidants because it is made up of just four percent water while they are more diluted in fruits and vegetables because they are made up of up to 90 percent water.
Researchers discovered one serving of popcorn has up to 300mg of antioxidants - nearly double the 160mg for all fruits per serving.
They also found that the crunchy hulls of the popcorn have the highest concentration of antioxidants and fiber.
The scientists from the University of Scranton in Pennsylvania unveiled their discovery at a meeting of the American Chemical Society in San Diego.
Researcher Joe Vinson said: 'Those hulls deserve more respect. They are nutritional gold nuggets.'
