Only about 3-percent of the nation is vegan, but big business sees a growth opportunity. Nina Guilbeault is cofounder of Plant Futures, a nonprofit affiliated with UC Berkeley’s Haas School of Business. She joins host Krys Boyd to discuss companies working to make vegan foods more accessible to the general public, and how food movements catch on. Her book is “The Good Eater: A Vegan’s Search for the Future of Food.”
