Factors Influencing Food Choices in Different Sports: Importance of Sustainability, Performance and Health: A Cross-Sectional Study
Abstract Background: This study investigates food preferences among individuals active in different sports. Since food intake affects the carbon footprint, it is of interest to investigate influencing factors of food choices regarding sustainability. Physically active individuals are in need for high intakes of energy and protein in order to maintain their performance. Little is known about what influence food choices in this population. Method: A survey of a sample of 367 individuals was conducted in German and Swedish gyms, climbing halls and CrossFit boxes. Therefore, a questionnaire was developed to capture information about factors influencing food choice and consumed protein sources. Kruskal-Wallis-test tested significant differences between sport groups and physical activity levels.Results: The most frequently consumed animal-based protein were dairy-products, and the most frequently used plant-based source were grains. Taste and health were the main influences on food choices. Significant differences were observed between sport groups and physical activity levels. Sustainability was ranked as moderately important, with the highest importance in people active in the outdoor sports running and climbing. Participants with high physical activity levels and active in CrossFit rated performance more important than the rest of the sample and consumed protein supplements, eggs and poultry more frequently. Conclusion: Differences in food choices between various sports and physical activity levels were identified. Understanding the underlying influences on food choices might help to motivate a shift towards a more sustainable diet in athletes.
