This has been on my mind a lot in recent years. Dr. Mercola outlines some of the high level concerns of mass-produced food here in his article about vegetable nutrition. It may surprise a lot of folks to know how little nutrition they are getting from their “healthy” foods, as he points out here:
“In fact, the average vegetable found in today’s supermarket is anywhere from 5 percent to 40 percent lower in minerals such as magnesium, iron, calcium and zinc than those harvested just 50 years ago.
Today’s vegetables are larger, but do not contain more nutrients. Jumbo-sized produce actually contains more “dry matter” than anything else, which dilutes mineral concentrations.”
This is not a Mercola endorsement, but I’m reading this same information in multiple sources lately and thought it worth sharing. Some interesting, related information can be found in the recent book, Eat This, Not That
While on the topic – I’d love to know from anyone in Knoxville if they endorse/recommend any local growers? When I moved, my trusted farmer’s market got too far away and I’d like to find some local sources for fresh, organic foods. Please comment here.
