The Basics of Nutrition

Macronutrients: The Building Blocks of Nutrition

1. Carbohydrates

   • Primary source of energy for the body.
   • Found in foods like fruits, vegetables, grains, and legumes.
   • Aim for complex carbohydrates that provide sustained energy, such as whole grains and starchy vegetables.

2. Proteins

   • Essential for muscle repair, growth, and maintenance.
   • Found in foods like meat, poultry, fish, dairy, eggs, and plant-based sources like beans and tofu.
   • Include a variety of protein sources in your diet to ensure you're getting all essential amino acids.

3. Fats

   • Provide energy, support cell growth, and help absorb vitamins.
   • Choose healthy fats like avocados, nuts, seeds, olive oil, and fatty fish.
   • Limit saturated and trans fats found in processed foods and fried foods.

Micronutrients: Essential for Health and Performance

1. Vitamins

   • Support various bodily functions, including immunity, energy production, and bone health.
   • Found in fruits, vegetables, dairy, meat, and fortified foods.
   • Aim for a colorful variety of fruits and vegetables to ensure you're getting a wide range of vitamins.

2. Minerals

   • Crucial for bone health, fluid balance, and muscle function.
   • Found in dairy products, leafy greens, nuts, seeds, and whole grains.
   • Pay attention to key minerals like calcium, magnesium, and potassium to support overall health.

Practical Tips for Fueling Your Body

1. Eat Balanced Meals

   • Include a combination of carbohydrates, proteins, and fats in each meal to provide sustained energy and support muscle recovery.

2. Time Your Meals and Snacks

   • Eat a balanced meal or snack containing carbohydrates and protein 2-3 hours before exercise to fuel your workout.
   • Refuel within 30 minutes to an hour after exercise with a combination of carbohydrates and protein to support muscle recovery.

3. Stay Hydrated

   • Drink plenty of water throughout the day to stay hydrated and support optimal bodily functions.
   • Hydrate before, during, and after exercise to replace fluids lost through sweat.

4. Choose Whole, Nutrient-Dense Foods

   • Opt for whole, minimally processed foods that provide essential nutrients and fuel your body efficiently.
   • Limit processed foods high in sugar, salt, and unhealthy fats, which can negatively impact performance and health.

5. Experiment and Listen to Your Body

   • Pay attention to how different foods make you feel and adjust your diet accordingly.
   • Experiment with meal timing, portion sizes, and food combinations to find what works best for your body and performance goals.

Supplements: Do You Need Them?

While a well-balanced diet should provide most of the nutrients your body needs, certain supplements can be beneficial for athletes and active individuals. Consider consulting with a registered dietitian or sports nutritionist to determine if supplements are necessary for you. Some commonly recommended supplements include:

• Protein powder: Helps meet protein needs, especially for athletes with higher protein requirements.
• Creatine: Supports muscle strength and power output during high-intensity exercise.
• Omega-3 fatty acids: Aid in reducing inflammation and supporting heart health.
