| Came across this interesting wire article about lower nutrients in modern vegetable varieties this morning -- thought it would interest some of the readers on this forum: Nutrient content in veggies declines amid bigger yields.
Here's one quote from the article:
"The tradeoff is that the faster-growing plants aren't able to acquire the nutrients that their slower-growing cousins can, either by synthesis or from the soil. He said there also are differences in the amounts of nutrients lost in differing varieties of wheat and broccoli."
