In the last six months, at least a dozen food companies and restaurant businesses have announced plans to reformulate products to eliminate ingredients. “To me, this has gone way beyond anything that could even be remotely considered a fad and become a powerful trend,” said Carl Jorgensen, director for global consumer strategy focusing on wellness at Daymon Worldwide, a consulting firm.
