I’ve written a lot about the benefits of shopping entirely at farmers markets, the difference between organic/GMO/seasonal, and how food is more important than working out. These topics have interested many people with many asking for more data.
Here is one piece, possibly the most important in explaining our obesity epidemic. The findings reveal farming practices and seed choice that have led to lower quality food. Compared on a nutrient-nutrient basis it can be a 1/3 drop in nutrient level for some foods.
This means that the typical person will need to eat 3x as much to obtain the proper nutrients. If true, that would provide the ideal explanation for our overweight problems. It’s not so much our sedentary lifestyle or even our poor choices in food, but our simple desire to get the nutrients our bodies need.
The report is worth a read and I will be sharing several more like it over the coming days.
“High yields and jumbo produce deliver more water, starch, and sugar per serving, but less vitamins, minerals and antioxidants.”
“Farmers have doubled or tripled the yield of most major grains, fruits and vegetables over the last half-century. They have done so by capitalizing on the work of plant scientists, crop breeders and companies manufacturing a wide range of inputs—from fertilizer to water, pesticides, sophisticated machinery and diesel fuel.
But American agriculture’s single-minded focus on increasing yields over the last half-century created a blind spot where incremental erosion in the nutritional quality of our food has occurred. This erosion, modest in some crops but significant in others for some nutrients, has gone largely unnoticed by scientists, farmers, government and consumers.”
