Planning An Athlete's Diet: The Foundation Stones

Planning an athlete's diet is a complex process that requires careful consideration of several factors. The diet should be tailored to the individual athlete, taking into account their specific sport, goals, food preferences, and practical challenges. The foundation of an athlete's diet should be foods rich in unrefined carbohydrates, such as wholegrain breads and cereals, which provide a good source of long-lasting energy. Additionally, athletes should ensure they are meeting their vitamin and mineral needs, as well as consuming enough protein to support muscle growth and repair.

Carbohydrates

The amount of carbohydrates an athlete should consume depends on their exercise level and intensity. For example, those who participate in light-intensity exercise for 30 minutes per day may require 3 to 5 grams of carbohydrates per kilogram of body weight, while those undertaking extreme endurance exercise for more than four hours daily may need up to 12 grams per kilogram. It is important for athletes to adjust their carbohydrate intake to match their activity level, ensuring they have sufficient energy to perform at their best.

Athletes can also include more refined carbohydrate foods in their diet, such as white bread, jams, and lollies. These foods can help boost overall carbohydrate intake, which is especially beneficial for very active individuals. However, it is important to note that these refined carbohydrates are often processed and high in added sugars, so they should be consumed in moderation as part of a balanced diet.

To ensure they are meeting their carbohydrate needs, athletes can refer to guidelines based on grams of carbohydrate intake per kilogram of body weight. Additionally, seeking guidance from a sports nutritionist can help athletes tailor their diet to their specific needs, taking into account their sport, goals, and individual preferences. By carefully planning their carbohydrate intake, athletes can optimise their energy levels and enhance their performance.

Proteins

A well-planned, nutritious diet is key to an athlete's performance. The basis of an athlete's diet should be foods rich in unrefined carbohydrates, like wholegrain breads and cereals. Carbohydrates are important for fuelling and recovery, and athletes should adjust their intake according to their exercise level. For example, athletes who exercise strenuously for more than 60 to 90 minutes every day may need to increase their carbohydrate intake.

In addition to carbohydrates, athletes should also ensure they are consuming enough protein to promote muscle growth and repair. Protein is essential for athletes as it helps to build and maintain muscle mass. It is particularly important for strength and power athletes, such as weightlifters and sprinters, who require a lot of muscle power for their sport.

There are two main types of protein: complete and incomplete. Complete proteins contain all the essential amino acids that the body needs but cannot produce itself, while incomplete proteins are missing one or more of these amino acids. Animal sources of protein, such as meat, poultry, fish, eggs, and dairy, are complete proteins. Plant sources of protein, such as beans, legumes, nuts, and seeds, are incomplete proteins. However, by combining certain plant foods, such as rice and beans, it is possible to create a complete protein.

Athletes should aim to include a variety of protein sources in their diet to ensure they are getting all the essential amino acids. Good sources of protein for athletes include lean meats, poultry, fish, eggs, dairy, beans, legumes, nuts, and seeds. Protein supplements, such as whey protein powder, can also be useful for athletes who need to increase their protein intake. However, it is important to note that whole food sources of protein are generally preferable as they provide additional nutrients, such as vitamins and minerals.

Vitamins and minerals

The basis of an athlete's diet should be foods rich in unrefined carbohydrates, like wholegrain breads and cereals. Athletes should also eat plenty of fruits, vegetables, whole grains, seafood, low-fat dairy, and legumes, while minimising high-fat foods such as biscuits, cakes, pastries, chips and fried foods.

Vitamins are organic compounds that are essential for the proper functioning of the body. They are involved in a wide range of metabolic processes, including energy production, bone health, immune function, and more. There are two main types of vitamins: water-soluble vitamins and fat-soluble vitamins. Water-soluble vitamins, such as vitamin C and the B vitamins, are easily absorbed by the body and are necessary for energy production and nervous system function. Fat-soluble vitamins, such as vitamins A, D, E, and K, are stored in the body's fat tissues and are important for maintaining healthy skin, bones, and vision.

Minerals are inorganic compounds that are also essential for the proper functioning of the body. They are typically divided into two categories: macrominerals and trace minerals. Macrominerals, such as calcium, magnesium, and potassium, are needed in larger amounts and play a role in bone health, muscle function, and fluid balance. Trace minerals, such as iron, zinc, and selenium, are needed in smaller amounts but are still crucial for processes like oxygen transport, immune function, and metabolism.

Athletes may have specific vitamin and mineral requirements depending on their sport, training intensity, and individual needs. For example, endurance athletes may require additional vitamin C to support immune function, while those who train outdoors may need more vitamin D due to its role in bone health. It is important for athletes to work with a sports nutritionist to ensure their diet is tailored to their specific needs and provides adequate vitamins and minerals.

In addition to a well-planned diet, athletes may also benefit from taking targeted vitamin and mineral supplements to ensure they are meeting their nutritional requirements. However, it is always best to prioritise obtaining nutrients from whole foods whenever possible, as they provide a more bioavailable form of these compounds.

Tailoring to the individual

Sports nutrition plans should be tailored to the individual athlete, taking into account their specific sport, goals, food preferences and practical challenges. For example, athletes who exercise strenuously for more than 60 to 90 minutes every day may need to increase their energy intake, particularly from carbohydrate sources. Carbohydrates are important for fuelling and recovery, and the amount an athlete needs will depend on their exercise level. For instance, an athlete doing light intensity exercise for 30 minutes a day will need 3 to 5 g/kg/day, while an athlete doing extreme endurance exercise for more than 4 hours a day will need 8 to 12 g/kg/day.

Athletes should also consider their protein and fat intake. Protein is important for muscle growth and repair, and guidelines for protein intake are also available based on grams per kilogram of body weight. Most athletes should follow similar recommendations for fat intake as the general community, with a preference for fats from olive oils, avocado, nuts and seeds. High-fat foods such as biscuits, cakes, pastries, chips and fried foods should be minimised.

Athletes should also ensure they are getting adequate vitamins and minerals to protect their body from injury. This means planning meals ahead and always having snacks on hand, as well as eating foods rich in vitamin C, vitamin D, magnesium, zinc and calcium.

Fats

An athlete's diet should be based on foods rich in unrefined carbohydrates, like wholegrain breads and cereals. Foods such as these should form the basis of an athlete's diet, with the addition of other foods to boost carbohydrate intake, particularly for very active people. An athlete's diet should also be rich in vitamins and minerals, and protein to promote muscle growth and repair.

The current recommendations for fat intake are for most athletes to follow similar recommendations to those given for the general community. This means that athletes should aim to get their fats from olive oils, avocado, nuts and seeds. Foods such as biscuits, cakes, pastries, chips and fried foods are high in fat and should be minimised in an athlete's diet.

The Nordic diet, which is based on the traditional diets of Nordic countries, emphasises local, sustainably sourced foods like fruits, vegetables, whole grains, seafood, low-fat dairy, and legumes. It restricts foods that are processed, refined, or high in added sugar. As this diet permits many foods that are rich in carbohydrates, it can provide plenty of long-lasting energy for endurance athletes.

Athletes who exercise strenuously for more than 60 to 90 minutes every day may need to increase their energy intake, particularly from carbohydrate sources. However, they should still follow the general recommendations for fat intake.
