WSU Researchers Say Organic is More Nutritious

"Organically grown foods generally hold more nutrition value than conventionally grown foods, according to a study co-authored by three WSU researchers.

According to the study, organic plant-based foods contain higher levels of eight of 11 nutrients studied, including significantly greater concentrations of the health-promoting polyphenols and antioxidants.

The study, co-authored by professor Neal Davies of the WSU College of Pharmacy, horticulture professor Preston Andrews and Jaime Yanez, Davies’ graduate student, is the first in-depth review of the published scientific literature on the nutritional benefits of organic food completed since 2003, Andrews said.

“Where there were overall combined results, there was a bigger difference more frequently in favor of organic foods,” Andrews said.

The study concluded that organically grown plant-based foods are on average 25 percent more nutrient dense, thus delivering more essential nutrients per serving or calorie consumed."
