Potato freaks rejoice: Eating potato puree is just as effective as carbohydrate gels for boosting exercise performance in trained athletes, reveals a new study.
- Athletes can choose potatoes as the best race-fueling option for a quick carbohydrate boost during exercise
- Eating potato puree during prolonged exercise promotes carbohydrate availability during exercise
- Potatoes can be used as a savory alternative to sweetened commercial gels for athletes to improve their exercise performance

Is Potato Good for Athletes?
"Potatoes are a promising alternative for athletes because they represent a cost-effective, nutrient-dense and whole-food source of carbohydrates," the researchers reported in the Journal of Applied Physiology. "Furthermore, they serve as a savory race fuel option when compared (with) the high sweetness of (carbohydrate) gels."
Consuming potato puree during prolonged exercise works just as well as a commercial carbohydrate gel in sustaining blood glucose levels and boosting performance in trained athletes, scientists report.
Details of the Study
Participants were randomly assigned to one of three conditions during the experiments: They would consume either water alone, a commercially available carbohydrate gel or an equivalent amount of carbohydrates obtained from potatoes.
Findings of the Study
"We found no differences between the performance of cyclists who got their carbohydrates by ingesting potatoes or gels at recommended amounts of about 60 grams per hour during the experiments," Burd said. "Both groups saw a significant boost in performance that those consuming only water did not achieve."
Plasma glucose concentrations went up by a similar amount in those consuming potatoes and gels. Their heart rates increased by a similar amount over the water-only cyclists, and they were speedier on the time trial.
Those consuming potatoes experienced significantly more gastrointestinal bloating, pain and flatulence than the other groups, however. This may be a result of the larger volume of potatoes needed to match the glucose provided by the gels, Burd said.
"Nevertheless, average GI symptoms were lower than previous studies, indicating that both (carbohydrate) conditions were well-tolerated by the majority of the study's cyclists,"the researchers wrote.
"All in all, our study is a proof-of-concept showing that athletes may use whole-food sources of carbohydrates as an alternative to commercial products to diversify race-fueling menus,"Burd said.
