Dan Kittridge, farmer and entrepreneur, really cares about the declining nutritional value in most foods found even in the finest grocery stores. That's because most farmers today don't realize that decades of growing the same crop in the same fields gradually depletes the soil of minerals and micro nutrients that are essential for human health. They think that putting back one or two of the minerals is enough when, in truth, there are scores of natural components of good soil that are completely missing on corporate farms today. And some of them look gorgeous in the stores. Dan found a way to stop being fooled by appearances. He produced a portable meter that can be taken to the store and measure for yourself yourself just how nutritious - or not so nutritious - those veggies really are.
