Dietary restrictions, such as those for food allergies, gluten intolerance, or veganism, can significantly influence nutrition for athletes. These restrictions may limit certain food groups, potentially creating nutrient gaps essential for performance and recovery. Athletes must strategically include alternative sources of protein, carbohydrates, vitamins, and minerals to ensure adequate intake. For instance, a vegan athlete might need to focus on plant-based protein sources like beans, lentils, and quinoa. Proper planning is crucial for meeting energy needs while adhering to dietary restrictions, ensuring optimal performance and health.
