Phil Lempert, known as the Supermarket Guru, has released his annual list of top 10 trends. He indicates supermarkets are changing to respond to customers' demands. As consumers look to save money and time, while improving health, grocers are adding protein-packed breakfast choices and healthful snacks. They are also making it easier to shop using mobile applications. Lempert sees supermarkets as a gathering place or a community center as a top trend.
