Marijuana was a major political trend in 2014, and now it's moving to the food world.

Hemp will become more mainstream and sought after as the popular seed next year, said Badaracco.

Hemp, which is a good source of fiber and protein, has a nutty flavor and also has Omega-3 fatty acids.

"We expect to see hemp hearts in more cereals and other foods, obviously there is no intoxication effect, but its popularity has to be tied to the marijuana culture explosion," said McCauley.
