For high school athletes, performance isn’t just about showing up to practice or lifting in the gym. What happens in the kitchen and at the dinner table plays a huge role in strength, endurance, and recovery.
Unfortunately, most young athletes—and parents—overlook one of the most controllable factors in performance: nutrition.
The right fuel can help athletes:
- Stay energized during games and training
- Build strength and muscle more effectively
- Recover faster and reduce soreness
- Perform consistently, not just on their best days
Let’s break down exactly what high school athletes should be eating to stay ahead of the competition.
Why Nutrition Impacts Performance So Much
Training creates demands on the body—energy is burned, muscles break down, and hydration levels drop. Without proper fuel, it’s harder to:
- Keep energy high during practices and games
- Gain strength and speed
- Recover between sessions
- Stay focused, sharp, and injury-free
Athletes who skip meals, rely on junk food, or neglect hydration often feel sluggish, fatigued, or inconsistent. Over time, this can stall progress and limit performance.
If the goal is to improve—nutrition can’t be an afterthought.
What High School Athletes Should Be Eating
Think of nutrition as having three key pillars: carbohydrates, protein, and healthy fats. Balance these well, and the body will have the fuel it needs to perform.
1. Carbs = Energy for Training and Competition
Carbohydrates provide the body’s quickest and most accessible energy source, especially for athletes doing speed, power, or endurance work.
Smart carb choices include:
- Rice, oats, whole grain bread, potatoes, fruit, pasta
Athletes should include carbs:
- At every main meal
- 1-2 hours before practice or games for extra energy
2. Protein = Muscle Recovery and Strength Gains
Protein helps repair muscles after workouts and supports building strength. Without enough protein, athletes may struggle to recover or gain lean muscle.
Best protein sources:
- Eggs, chicken, turkey, beef
- Fish
- Greek yogurt
- Protein shakes
Quick tip: Aim for protein at every meal and snack to support consistent recovery.
3. Healthy Fats = Long-Lasting Energy and Joint Health
Fats support endurance, hormone health, and joint recovery—essential for athletes in demanding sports seasons.
Good fats include:
- Avocado
- Nuts and seeds
- Olive oil
- Fatty fish like salmon
Skip greasy fast food or heavily processed snacks—they often slow athletes down instead of fueling them properly.
4. Hydration = The Performance Difference Maker
Even slight dehydration can impact:
- Strength and power output
- Focus and decision-making
- Endurance
Athletes should:
- Drink water consistently throughout the day
- Include electrolytes during long practices or in hot weather
- Monitor hydration—clear to pale yellow urine is ideal
