Pricey Protein

On my quest to eat good quality protein I am faced with information such as this from The Week Magazine and Bloomberg:

Protein is getting pricey. The cost of beef, beans, bacon, and nine other protein sources jumped 28 percent in the last five years. In 2014 alone, protein prices have risen roughly 5 percent—twice the pace of increase for any other food group.

I suppose this can assist in the general population also eating more vegetables which will help everyone with their overall health. I just read somewhere that planting a garden is like printing money - for what might be very little effort, you can feed yourself and thereby save the outlay of cash. "A penny saved is a penny earned", after all.
