Bud Light’s Super Bowl commercial pointing out that its competitors – Coors Light and Miller Lite – use corn syrup in their products while Bud Light doesn’t was not appreciated by many in the corn industry.

Shortly after the commercial aired, the National Corn Growers Assn., which represents 40,000 corn farmers nationwide, tweeted:

Mark Recker, president of the Iowa Corn Growers Assn., said, “As a family farmer, I am disappointed that Bud Light chose to denigrate corn in their Super Bowl ad as part of a marketing scheme to attack their competition.”

Recker added, “I am proud of the generations of farmers that grow corn that is used in over 4,000 everyday products, from corn-fed beef to ethanol to bourbon to makeup. Iowa is the number-one corn-producing state, and [corn is] the top crop grown in our country. This attack especially hits home at a time when farmers are hurting due to challenging economic conditions. Corn is a homegrown renewable crop that feeds and fuels my family and yours.”

Recker concluded, “Please leave us out of the beer wars. Support your local corn farmers by standing with us and choosing products that include corn.”

Also on Twitter, farmer Kevin Ross showed himself dumping out his Bud Light.
