Association of Consumption of Higher Quality Carbohydrate Foods with Physiological Parameters and Health Risk Factors
Nutrition Impact
An NHANES analysis to assess whether quality measures of carbohydrate-based foods provide differentiations such that consumption of more higher quality carbohydrate-based foods are associated with improved health parameters/lower risk factors than consumption of lower quality carbohydrate-based foods. NHANES 2013-2018 data will be used, as well as four approaches to assess quality of carbohydrate foods: 10:1:1 (ratio of carbohydrate:dietary fiber:added sugars); Carbohydrate Food Quality Score (CFSQ)-4 for non-grain foods; CFSQ-5 for-grain based foods; and a combination of CFSQ-4 and CSFQ-5.
Long-Term Effects of a Potato-Based Food Pattern vs a Rice/ Pasta-Based Food Pattern on Fasting and Postprandial Cardiometabolic Health
Maastricht University
A clinical trial assessing the effect of a potato-based, carbohydrate-rich, healthy eating pattern, compared to the same meal with white rice or pasta in overweight and obese healthy adults. The study will measure changes in blood sugar concentration, along with glucose and lipid metabolism endpoints, all of which are considered well-established markers for cardiovascular disease.
HEALTHY LIFESTYLES
ATHLETIC PERFORMANCE
White Potatoes as an Optimal Recovery Strategy from Exercise in Active Females
Liverpool John Moores University
A clinical trial evaluating whether a white potato-based diet is as effective as a traditional high-carbohydrate diet for recovery from aerobic exercise in active females. The potato-based diet will include various preparations of potatoes, including roasted and fried. The study will also investigate if the effects of a white potato-based diet on recovery can be further improved using exogenous ketone esters, a cutting-edge sports nutrition aid used to enhance adaptation to training.
Effect of Pre-Exercise Carbohydrate Feeding Source on Mtabolic Response and Exercise Performance
University of Manitoba
A clinical cross-over trial among healthy, active adults investigating the effect of pre-exercise carbohydrate feeding using three different carbohydrate sources—potato, pasta and a sport supplement—or no carbohydrate control on exercise performance. Performance measured during the time trial will include heart rate, average power (watts), and time to completion (minutes).
A Short-Term Potato-Enriched Diet to Support Muscle Accretion and Promote Substrate Metabolism Adaptations in Recreationally Active Individuals
Swinburne University of Technology, Australia

The study will measure differences in muscle protein response to exercise in healthy, young males and will include potatoes in various forms (e.g., mashed, baked, chips), with 50% of daily protein derived from potatoes in the non-animal protein diet for a two- week period.
White potatoes as an effective dietary source during weight loss by energy restriction and exercise training
Liverpool John Moores University
A clinical trial investigating if energy restriction, using a potato-based diet plus aerobic exercise, can enhance skeletal muscle quality. Participants will follow an energy balance (EB) diet for 5 days followed by an energy deficient (ED) diet for another 5 days; the percentage of total energy from potato-based sources will be >60% during EB and >65% during ED diets The rates of protein synthesis, abundance and degradation will be analysed to determine skeletal muscle metabolism and function.
Potato-based whole-foods versus designer sports nutrition; how potatoes and potato-based products can accelerate recovery following exercise
Maastricht University
A randomized crossover trial in 10 well-trained endurance ahtletes investigating whether potato-based food products are as effective as designer sports supplements to replenish energy stores post-exercise in endurance athletes. Athletes will be given multiple forms of potatoes/potato products (e.g., baked potatoes, potato gnocchi, potato croquettes, etc.) for two weeks, and the ability of potatoes versus designer sports supplements to replenish muscle and liver glycogen stores throughout 24 hours of post-exercise recovery will be measured. Results could potentially reinforce that potato-based food products are an effective whole-food source to improve post-exercise recovery, as compared to commercially available supplements.
