McDonald’s went from hating on foodie ingredients to opening a hipster café. Now, it plans on incorporating the one vegetable it mocked in its Big Mac ad into new products – kale. Is McDonald’s having an identity crisis? Has it lost its fast food soul by trying to be all things to all people?

With McDonald's challenged by fast food chains like Chipotle and Subway – which emphasise fresher ingredients and let people choose what goes into their products – the burger chain is expanding the "create your own taste" option. But can it boost sliding sales?

People want big brands to consider the planet as well as their patrons. Chipotle is ahead in this game, with the recent release of their app-game hybrid campaign The Scarecrow demonstrating the power of emotional storytelling.

The American appetite for fast food is waning. Instead, people are hungry for experiences. In response, fast food chain Taco Bell has launched an upmarket Mexican-American restaurant brand, aimed at a Millennial demographic demanding fresh, gourmet food in a casual setting.
