PROTEINS

Functions of Proteins

1. Muscle Repair and Growth: Proteins are made up of amino acids, which are the building blocks of muscle tissue. After intense workouts, muscles undergo tiny tears that require repair. Protein intake helps in rebuilding these muscles stronger and larger.

2. Enzyme Production: Proteins are involved in the creation of enzymes that catalyze biochemical reactions within the body, including those that convert food into energy and repair tissues.

3. Hormone Regulation: Certain proteins function as hormones that regulate various bodily functions, such as growth hormone and insulin.

4. Immune Function: Antibodies, which are proteins, play a crucial role in the immune system by identifying and neutralizing pathogens like bacteria and viruses.

5. Structural Support: Proteins like collagen provide structural support to tissues such as skin, hair, and connective tissues, maintaining the integrity and function of organs.

Sources of Protein

• Animal-Based Sources: These include meat (beef, chicken, turkey, pork), fish (salmon, tuna, mackerel), eggs, and dairy products (milk, cheese, yogurt). Animal proteins are considered complete proteins as they contain all essential amino acids.

• Plant-Based Sources: These include legumes (beans, lentils, chickpeas), nuts (almonds, walnuts), seeds (chia, flaxseeds, hemp seeds), whole grains (quinoa, brown rice), and soy products (tofu, tempeh, edamame). Some plant proteins may be incomplete but can be combined to provide all essential amino acids.

• Protein Supplements: Whey protein, casein protein, and plant-based protein powders (pea, hemp, rice) can help meet protein needs, especially for those with higher protein requirements.

Optimizing Protein Intake for Fitness

1. Determine Your Protein Needs: The average adult needs about 0.8 grams of protein per kilogram of body weight. However, for those involved in regular intense exercise, this can increase to 1.2-2.0 grams per kilogram. For example, a 70 kg person may need between 84-140 grams of protein daily, depending on their activity level.

2. Distribute Protein Intake Throughout the Day: Aim to consume protein at each meal to ensure a steady supply of amino acids for muscle repair and growth. This also helps in maintaining satiety and energy levels.

3. Post-Workout Protein: Consuming protein within 30 minutes to 2 hours after exercise can maximize muscle protein synthesis. This can be achieved through a protein-rich meal or a protein shake.

4. Combine Protein with Carbohydrates: Post-workout, combining protein with carbohydrates can help replenish glycogen stores and improve recovery. A ratio of 3:1 carbs to protein is often recommended for optimal recovery.

5. Quality Over Quantity: Focus on high-quality protein sources that provide a complete profile of essential amino acids. Diversify your protein sources to ensure you get a broad range of nutrients.

Examples of Protein-Rich Meals

• Breakfast: Greek yogurt with mixed berries and a sprinkle of chia seeds.

• Lunch: Grilled chicken breast with quinoa and steamed vegetables.

• Snack: A handful of almonds or a protein smoothie made with whey or plant-based protein powder.

• Dinner: Baked salmon with a side of sweet potatoes and sautéed spinach.

• Post-Workout: A protein shake with a banana or a turkey sandwich on whole grain bread.
