I recently learned of a study that shows we are getting fewer nutrients in our vegetables & fruits. Compared to studies from the 1950’s, today’s vegetables and fruits contain less protein, iron, calcium, and vitamin C. At the same time, carbohydrate levels have increased, and here’s why scientists think this is happening.
Rising Levels of CO2
Scientists believe that rising levels of carbon dioxide in the atmosphere are causing the loss of nutrients. More carbon dioxide equals lower levels of essential minerals in the soil. The higher CO2 levels are causing the plants to produce more carbohydrates at the expense of other essential nutrients. So plants are growing just fine with these higher CO2 levels, but they now have lower levels of minerals. Nice looking plants, little nutritional value.
