When it comes to repairing muscles, protein is the most important nutrient. Protein helps repair tissue damaged by exercise, and it can also be used to produce energy for muscle contractions when other sources of energy are not available. Carbohydrates are also key to supporting muscle growth and repair, as they help fuel workouts and rebuild muscles post-workout. In addition, zinc, calcium, magnesium, and vitamin D are important nutrients for muscle repair and recovery.

Carbohydrates for energy and glycogen restoration
Carbohydrates are essential for energy and glycogen restoration. Carbohydrates are a macronutrient that provides the body with its main source of energy. Glucose, which is derived from carbohydrates, is the primary source of energy for the brain. Carbohydrates are converted into glucose, which is either used immediately by the body for energy or stored in the liver and muscles as glycogen for later use.
Glycogen is the most important energy substrate during exercise, particularly at higher intensities. The body stores three-quarters of its total glycogen in the skeletal muscles to ensure a consistent supply of energy during exercise. The rate at which muscle glycogen is used is directly related to the intensity of physical activity. High-intensity exercise, such as sprinting, can quickly deplete glycogen stores in active muscle cells. Therefore, it is crucial to consume enough carbohydrates to restore muscle glycogen.
The post-exercise carbohydrate recommendation is 1 g/kg/BW per hour for four hours, followed by matching activity needs. However, it may not always be feasible to ingest such large amounts of carbohydrates. In such cases, combining a small amount of protein with fewer carbohydrates can stimulate endogenous insulin release, resulting in similar muscle glycogen repletion rates as higher carbohydrate ingestion.
Additionally, consuming carbohydrates during exercise can help maintain glycogen stores. Examples include energy drinks, bars, and gels. Long-term strategies to maintain glycogen stores include increasing fitness levels, which increases the maximal amount of glycogen stored per kilo of muscle mass, and decreasing exercise intensity, which reduces carbohydrate combustion.

Protein-rich foods for muscle repair
When it comes to repairing muscles, protein is an essential nutrient. It helps repair tissues damaged by exercise, and it can also be used to produce energy for muscle contractions when other energy sources are not available.
Protein-rich foods are a priority for building and repairing muscles. Here are some protein-rich foods that can help support muscle repair and growth:
Lean meats
Meats such as chicken, turkey, beef, and pork are excellent sources of high-quality protein and also provide important nutrients like iron and zinc.
Dairy
Greek yogurt, in particular, is a good source of protein and can be beneficial when consumed after a workout or before bed due to its mixture of fast- and slow-digesting proteins. Dairy protein powders, such as whey and casein, are also popular options for those looking to increase their protein intake.
Eggs
Eggs contain large amounts of the amino acid leucine, which is important for muscle building.
Plant-based sources
For those who avoid animal proteins, plant-based sources such as soy, quinoa, and edamame (immature soybeans) are complete proteins, meaning they contain all the essential amino acids needed by the body.
In addition to protein-rich foods, staying hydrated is crucial for muscle repair. Water regulates body temperature, lubricates joints, and transports nutrients.
It is also important to note that while supplements can be beneficial, it is always a good idea to consult with a doctor or healthcare professional before adding them to your daily regimen.

Healthy fats to minimise inflammation
Healthy fats are an important component of any diet, offering a range of health benefits. They are particularly useful in minimising inflammation, which is believed to play a central role in many chronic diseases, such as cancer, heart disease, diabetes, arthritis, depression, and Alzheimer's.
Inflammation is the body's natural response to illness, injury, or infection, and usually resolves on its own. However, sometimes inflammation persists, even when there is no foreign invader, and this is when it can become harmful. Dietary fats can affect inflammatory responses, with both the amount and type of fat consumed influencing the effect.
Healthy fats that minimise inflammation include fatty fish, such as salmon, herring, mackerel, sardines, tuna, striped bass, and anchovies. These are rich in omega-3 fats, which have been shown to help speed up recovery by preventing excessive or prolonged inflammation. Omega-3 fats can also be sourced from plant-based foods, such as nuts and seeds, and cooking with canola oil or extra-virgin olive oil.
In addition to omega-3 fats, vitamin C, also known as ascorbic acid, is a powerful antioxidant that can help to reduce inflammation. A diet rich in fruits and vegetables is a good way to increase vitamin C intake.
It is also important to consider how you cook your food. Baking, steaming, or stir-frying are preferable to deep frying or grilling, as grilling meat, especially red meat, can create compounds associated with cancer.
By incorporating these healthy fats and cooking methods into your diet, you can help to minimise inflammation and support overall health.

Zinc-rich foods for tissue repair
While protein is the primary nutrient that helps repair muscle tissue, zinc is a component of many enzymes and proteins, including those needed for tissue repair and growth. Consuming zinc-rich foods can help speed up wound healing and tissue repair.
Zinc is a top mineral for boosting immunity. A healthy amount of zinc in your diet has been linked to an improved immune system and faster wound healing. It may also help shorten the common cold. Research has found that zinc supplementation could reduce the length of the common cold by 2.25 days.
Zinc is commonly found in animal products, and the body absorbs zinc better from animal-based foods than plant-based foods. Vegetarians, vegans, and people on restricted diets are therefore more likely to experience zinc deficiency.
- Meat: Meat is an excellent source of zinc. A 100-gram serving of raw ground beef provides 44%–60% of the Daily Value (DV).
- Shellfish: Shellfish are healthy, low-calorie sources of zinc. Oysters are particularly rich in zinc, with six medium oysters providing 300% of the DV for males and 413% for females. Alaska king crab and smaller shellfish like shrimp and mussels are also good sources.
- Poultry: Chicken and turkey are good sources of zinc.
- Seafood: Crab and lobster are both zinc-rich foods.
- Pulses and legumes: Legumes are a good source of zinc. Peanuts, while technically a legume, also provide zinc.
- Seeds: Hemp, pumpkin, squash, and sesame seeds contain significant amounts of zinc.
- Nuts: Pine nuts, cashews, almonds, and peanuts are good sources of zinc.
- Whole grains: Zinc is found in whole grains, including breakfast cereals.
- Dairy products: Milk and yogurt are good sources of zinc.
- Vegetables: Vegetables like mushrooms, spinach, broccoli, kale, and garlic contain zinc.
- Dark chocolate: Chocolate also contains zinc, but it is best to consume it in moderation as part of a balanced diet.
It is important to note that while supplements are available, it is best to speak to a doctor before taking them, as high doses of zinc from supplements can increase the likelihood of copper deficiency and interfere with the absorption of other nutrients.

Calcium and magnesium for muscle relaxation
Calcium and magnesium are essential nutrients for muscle relaxation and repair. Calcium is involved in muscle contractions and nerve signalling, while magnesium helps the muscles relax after contracting.
Calcium is an important component of bones and teeth, and it plays a crucial role in muscle contractions and nerve signalling. It binds to proteins such as troponin C and myosin, changing their shape and generating a contraction. This process is essential for our muscles to function properly, allowing us to flex, move, and pump blood through our hearts.
Magnesium, on the other hand, acts as a natural calcium blocker and helps muscles relax. It competes with calcium for binding spots on muscle cell receptor proteins. When magnesium binds to these proteins, it blocks the sites for calcium, allowing the muscles to relax. This balance between calcium and magnesium is vital for proper muscle function. If the body does not have enough magnesium, the muscles may contract too much, leading to cramps or spasms.
Magnesium is involved in over 600 cellular reactions and is essential for muscle relaxation and recovery. It is recommended for people who engage in regular exercise as it helps prevent and relieve muscle soreness and tension. Magnesium can be found in whole grains, beans, dark chocolate, nuts, and leafy green vegetables like spinach. However, it is important to note that magnesium deficiency is common, and supplements are available to ensure adequate intake.
In addition to calcium and magnesium, other nutrients play a role in muscle repair and recovery. Protein is crucial for repairing damaged muscle tissues and synthesizing new satellite cells. Carbohydrates and healthy fats are also important for restoring energy and minimizing inflammation. Zinc-rich foods, such as meat, fish, shellfish, pulses, seeds, nuts, and whole grains, can aid in wound healing and tissue repair.
