Avocado toast, unicorn frappuccinos, and kale salads. Taking photos of your food and putting them on Instagram is a now a huge trend that's transforming markets in more ways than one. In this edition of the Odd Lots podcast we talk about how photogenic foods are impacting commodities prices, and how the retail market is actively courting Instagram 'influencers' who can promote their business. We speak with Amanda Topper, a food blogger who works as associate director of foodservice research at Mintel, as well as Julie Verhage, a Bloomberg reporter who's written about the impact of Instagram on commodities prices.
