+ AI supercharges data center energy use; bull sharks thrive in warming Gulf US Edition - Today's top story: Nutrition Facts labels have a complicated legacy â a historian explains the science and politics of translating food into information [View in browser]( US Edition | 17 July 2024 [The Conversation]
[The Conversation]( Which sounds more objective: Nutrition Facts, Nutrition Values or Nutrition Guide? Does 2,000 calories meet your daily energy needs, or would 2,350? Such are a few of the consequential decisions the FDA, USDA and other agencies pondered when designing that staid, black-and-white label gracing the side of your cereal box and countless other food items. You might have glanced at the Nutrition Facts label while deciding between two similar products at the grocery store â a little more fiber here or a little less salt there might have cinched your choice. But, as historian Xaq Frohlich of Auburn University notes, this label does much more than just provide consumers with nutritional information. âWhile envisioned as an education tool, I believe the [Nutrition Facts label in practice has worked more like a market infrastructure](,â he writes, âreshaping the food supply to meet shifting dietary trends and public health goals long before consumers find those foods at the supermarket.â Frohlich unpacks some of the political and technical choices behind the daily values percentages and serving sizes, among others â exploring how the way food is translated into information shapes the health of the nation.
