What are the key nutrients for enhancing athletic performance?.

To enhance athletic performance, key nutrients include:

1. Protein: Vital for muscle repair and growth, athletes should aim for about 1.2 to 2.0 grams per kilogram of body weight per day.
2. Carbohydrates: The primary energy source for athletes; complex carbs like whole grains provide sustained energy.
3. Fats: Essential for long-duration activities, healthy fats should make up about 20-35% of total daily calories.
4. Vitamins and Minerals: Micronutrients like vitamins B, C, D, and minerals such as calcium and iron support energy metabolism and muscle function.

Incorporating a balanced diet with these nutrients can lead to improved endurance, strength, and overall performance.
