You may not taste the diesel, but diesel is having an impact on products sold in the grocery store. Diesel fuel prices are significantly higher this year, and most if not all the products in your grocery store get there by truck. Iowa Department of Natural Resources energy analyst Jennifer Moehlmann says the trucking industry is feeling the pinch. “When their fuel costs more, they have to pass that cost along to their customers, so part of the increase in, say, milk prices can be attributed to higher fuel prices,” Moehlmann says. According to the latest state survey, diesel was selling for an average price of a-dollar-51 a gallon on November 15th. A gallon of skim milk is selling for around 2-40 while whole milk runs around three-dollars a gallon.
