How to fly off the supermarket shelves with Tessa Stuart

3 food challenger brands to watch: 

1. Caulirice - For setting bigger ambitions than only going up against niche products like quinoa. Instead, took their rice alternative right into the rice category. 

2. Ugly Drinks - For their counter-intuitive brand name and with an aim to change the nation's drinking habits by going up against the most loved and heavily marketed soft drink, Coke. 

3. Rude Health - For taking healthy products, making them in a better way than the dreary big brand 'wellness' alternatives and making them mainstream. And for not being po-faced about it either.
