Summary:
- The article discusses a study by scientists that has identified the genetic origins of humans' preference for carbohydrate-rich foods.
- Researchers found that a genetic variant associated with the ability to better digest starch and other carbohydrates likely evolved in early human populations as they transitioned to an agricultural lifestyle.
- This genetic adaptation may have provided a survival advantage by allowing our ancestors to better utilize the energy-dense carbohydrates in the starchy foods that became a staple of the human diet.
