What You'll Learn
A balanced diet provides essential vitamins and minerals
A balanced diet is key to an athlete's performance and overall well-being. It provides the essential vitamins and minerals that the body needs to function properly. Vitamins and minerals are micronutrients, which means that the body only needs small amounts of them to support bodily functions. However, meeting these needs is crucial for athletes to unlock their full potential.
Vitamins and minerals play a pivotal role in providing energy, supporting bodily functions, and facilitating recovery. For example, B vitamins, including thiamin, riboflavin, and niacin, are essential for producing energy from the fuel sources in our diet. Carbohydrates and protein foods are excellent sources of these vitamins. Calcium, found in dairy foods such as milk, yogurt, and cheese, is another important mineral for athletes as it helps build and protect the strong bones that athletes depend on.
Fruits and vegetables are also a great source of vitamins and minerals. A range of colours, including tomatoes, watermelons, carrots, mangoes, apricots, chickpeas, and eggplant, provide a wide range of vitamins and minerals such as vitamin C, B6, and B12. These vitamins and minerals are not only needed during a competition but also aid in the recovery process afterward.
In addition to vitamins, athletes need to ensure they are consuming adequate amounts of minerals. Iron is one such mineral that is particularly important for athletes, especially females and distance runners, as it is commonly depleted due to diets poor in meat, fish, and poultry. Iron-rich foods include eggs, leafy green vegetables, fortified whole grains, and lean meat.
While a balanced diet typically provides the essential vitamins and minerals in the recommended doses, athletes often resort to micronutrient supplementation to meet their increased needs. Research indicates that exercise intensity, duration, and character influence an athlete's micronutrient requirements. Thus, athletes should strategically examine the timing, amount, and nutritional value of their food consumption to ensure they are meeting their vitamin and mineral needs.

Carbohydrates are the body's main source of energy
Carbohydrates are necessary for the body's energy needs because they are converted into glucose, which is the body's preferred source of fuel. During exercise, the body breaks down stored glycogen and converts it back into glucose to be used for energy. The body can only store a limited amount of carbohydrates as glycogen, so it is important for athletes to ensure they are consuming enough carbohydrates to meet their energy requirements.
A balanced diet for athletes typically consists of around 60% carbohydrates, with the remaining intake comprising proteins and fats. Good sources of carbohydrates include fruits, vegetables and grains, especially whole grains like brown rice, oatmeal and whole-wheat bread. These foods provide not only the necessary fuel for athletic performance but also the fibre and other nutrients that contribute to overall health.
In the days leading up to a competition or high-intensity training, it is beneficial for athletes to focus on carbohydrate loading. This involves increasing carbohydrate intake to ensure optimal muscle glycogen storage. For events lasting longer than two hours, a high-carbohydrate diet in the preceding days can help to maximise energy levels and enhance performance.
While carbohydrates are crucial for energy, it is important to note that they should not be the sole source of fuel. Athletes also need to consume adequate amounts of protein, fats, vitamins and minerals to support their bodies and optimise their performance. A well-rounded, balanced diet is key to ensuring athletes have sufficient energy and the necessary nutrients to excel in their sport.

Proteins help build and repair muscles
A balanced diet is key to an athlete's performance and overall well-being. It provides the body with the right nutrients to function and grow, and this is especially important for athletes who exercise or lead very active lives.
Protein is one of the three macronutrients, along with carbohydrates and fats, that are the primary sources of energy from food. Protein helps to maintain and build muscle mass. Dietary protein is digested into amino acids, which are used as building blocks for the different tissues, enzymes, and hormones that the body needs to function.
Protein is important for muscle building and repair after exercise. While it contributes minimally to the body's energy needs, it is still crucial for athletes to consume enough protein as it supports the bodily functions that enable physical activity. For example, protein helps to produce the hormones that regulate metabolism and other physiological processes.
Athletes may need more protein than less-active individuals, but most get plenty through a healthy diet. Good sources of protein include fish, lean meats, and poultry, eggs, dairy, nuts, soy, and peanut butter. It is a myth that athletes need a huge daily intake of protein to build large, strong muscles. Muscle growth comes from regular training and hard work.
The recommended diet for athletes consists of about 60% carbohydrates, 20% protein, and 20% fat, although this may vary depending on the sport and the individual's specific needs. It is important to work with a dietitian to determine the right balance of macronutrients, as needs may change daily based on the level of physical activity.

Fats are crucial for nutritional needs
For athletes, a balanced diet is key to optimal performance. It ensures the body has the right nutrients to function at its best, both mentally and physically, and supports the immune system.
Fats are an essential part of a healthy diet, providing the body with energy and contributing to overall health. Fats are a highly efficient energy source, with 1 gram of fat providing 9 calories, more than double that of proteins and carbohydrates. This energy is stored for longer periods compared to other sources. While carbohydrates are the body's preferred energy source, during endurance activities, fat stores are used once glycogen stores are depleted.
The body requires a minimum fat intake of 20% of total energy to preserve athletic performance. This fat intake is crucial for meeting nutritional needs, providing essential fatty acids and fat-soluble vitamins A, D, E, and K. These vitamins are typically found in plants within fibrous cell walls, and the addition of dietary fats helps release them for absorption. For example, the bioavailability of lycopene in tomatoes increases from 6g to 28g when consumed with fat.
Monounsaturated and polyunsaturated fats, found in nuts, seeds, avocados, olive oil, and fatty fish, are particularly beneficial. These healthy fats help lower bad cholesterol and boost good cholesterol, reducing the risk of heart disease. They are also excellent sources of vitamin E, which is important for vision, brain function, and skin health. Omega-3 and omega-6, types of polyunsaturated fats, are essential fatty acids that the body cannot produce and must be obtained from the diet. Omega-3 fats have also been linked to enhanced female fertility.
While fat is crucial for nutritional needs, it is important to be mindful of the type and amount consumed. Trans fats, often found in processed foods, are manufactured and unhealthy and should be avoided. Saturated fats, found in fatty meats, high-fat dairy, and tropical oils, are not considered beneficial for health and should be consumed in moderation. Most health authorities recommend they comprise no more than 6% of daily calories.
In summary, fats are an essential component of an athlete's diet, providing energy and supporting the absorption of vital nutrients. However, it is important to prioritise healthy fats, such as monounsaturated and polyunsaturated fats, over saturated and trans fats, and to consume them in appropriate portions.

These include macronutrients (carbohydrates, proteins, and fats) and micronutrients (vitamins and minerals). Carbohydrates are an excellent source of fuel for athletes, and whole grains provide the energy, fiber, and other nutrients to keep them healthy. For events lasting longer than two hours, a high-carbohydrate diet is recommended in the days leading up to the event to ensure sufficient glycogen storage.
Protein is important for muscle building and repair, and while athletes may need more protein than less-active individuals, most get plenty through a healthy diet. Good sources of protein include fish, lean meats, poultry, eggs, dairy, nuts, soy, and peanut butter. Fat consumption should be at least 20% of total energy intake to preserve athletic performance and meet nutritional needs for essential fatty acids and fat-soluble vitamins.
Vitamins and minerals are essential for bodily function and athletic performance. B vitamins, including thiamin, riboflavin, and niacin, are important for producing energy, and calcium is crucial for protecting athletes' bones from stress fractures. Fruits and vegetables provide a wide range of vitamins and minerals, and their colours indicate different benefits: for example, a diet including tomatoes, watermelons, carrots, and mangoes will provide vitamin C, while apricots, chickpeas, and eggplant are a source of vitamin B6.
In addition to a balanced diet, athletes should ensure they are drinking enough fluids to stay hydrated during an event.
