Consumers are going nuts for almond milk, as it became the fastest growing non-dairy milk alternative in 2011 at the expense of soy milk. According to the latest figures from Packaged Facts, sales of almond milk increased 79 percent in the US last year, while sales of soy milk -- though still the most popular non-dairy milk alternative -- fell 15 percent between 2008 and 2010, reported online trade publication FoodNavigator.com last week.
