GMOs are not harmful. That’s the conclusion from Ruth MacDonald, a professor at Iowa State who holds a Ph.D. in human nutrition. She’s the source in a recent article by Holly Spangler on farmprogress.com, a sister site to Corn+Soybean Digest.

"There's never been any illness associated, and there's no evidence of long-term effects on human health," MacDonald says. "Consumption of foods with GMO technology are as safe as those grown without. There's no nutritional difference and no risk in genes expressed."

"People are much more likely to say they are willing to pay a premium for a product," he says. "People will tell you they're willing to pay twice as much as they actually are."
