"How to Get More Vitamins from Your Produce"

Fascinating post:

"Last year, a USDA research plant physiologist by the name of Dr. Gene Lester conducted a fascinating study on the phytochemical metabolism of two types of spinach. He wondered if, since spinach growing in the field relies so heavily on visible sunlight exposure for producing the phytochemicals that make humans want to eat it, perhaps exposing the spinach to light post-harvest continued to affect its phytochemical composition. And so he found out."

A good argument for going to the market every day for your produce, rather than buying a bunch and letting it sit in the fridge...
