Supports effective nutrient breakdown -
Athletes who exercise strenuously for more than 60 to 90 minutes every day may need to increase the amount of energy they consume, particularly from carbohydrate sources. The current recommendations for fat intake are for most athletes to follow similar recommendations to those given for the general community, with the preference for fats coming from olive oils, avocado, nuts and seeds.
Athletes should also aim to minimise intake of high-fat foods such as biscuits, cakes, pastries, chips and fried foods. After absorption, glucose can be converted into glycogen and stored in the liver and muscle tissue. It can then be used as a key energy source during exercise to fuel exercising muscle tissue and other body systems.
Athletes can increase their stores of glycogen by regularly eating high-carbohydrate foods. If dietary protein intake is insufficient, this can result in a loss of protein muscle tissue, because the body will start to break down muscle tissue to meet its energy needs, and may increase the risk of infections and illness.
Current recommendations for carbohydrate requirements vary depending on the duration, frequency and intensity of exercise. More refined carbohydrate foods such as white bread, jams and lollies are useful to boost the total intake of carbohydrate, particularly for very active people.
Athletes are advised to adjust the amount of carbohydrate they consume for fuelling and recovery to suit their exercise level. For example:. A more recent strategy adopted by some athletes is to train with low body carbohydrate levels and intakes train low. There is accumulating evidence that carefully planned periods of training with low carbohydrate availability may enhance some of the adaptations in muscle to the training program.
However, currently the benefits of this approach to athletic performance are unclear. The GI has become of increasing interest to athletes in the area of sports nutrition. However, the particular timing of ingestion of carbohydrate foods with different GIs around exercise might be important.
There is a suggestion that low GI foods may be useful before exercise to provide a more sustained energy release, although evidence is not convincing in terms of any resulting performance benefit. Moderate to high GI foods and fluids may be the most beneficial during exercise and in the early recovery period.
However, it is important to remember the type and timing of food eaten should be tailored to personal preferences and to maximise the performance of the particular sport in which the person is involved. A high-carbohydrate meal 3 to 4 hours before exercise is thought to have a positive effect on performance.
A small snack one to 2 hours before exercise may also benefit performance. It is important to ensure good hydration prior to an event. Consuming approximately ml of fluid in the 2 to 4 hours prior to an event may be a good general strategy to take.
Some people may experience a negative response to eating close to exercise. A meal high in fat, protein or fibre is likely to increase the risk of digestive discomfort. It is recommended that meals just before exercise should be high in carbohydrates as they do not cause gastrointestinal upset.
Liquid meal supplements may also be appropriate, particularly for athletes who suffer from pre-event nerves. For athletes involved in events lasting less than 60 minutes in duration, a mouth rinse with a carbohydrate beverage may be sufficient to help improve performance.
Benefits of this strategy appear to relate to effects on the brain and central nervous system. During exercise lasting more than 60 minutes, an intake of carbohydrate is required to top up blood glucose levels and delay fatigue.
Current recommendations suggest 30 to 60 g of carbohydrate is sufficient, and can be in the form of lollies, sports gels, sports drinks, low-fat muesli and sports bars or sandwiches with white bread. It is important to start your intake early in exercise and to consume regular amounts throughout the exercise period.
It is also important to consume regular fluid during prolonged exercise to avoid dehydration. Sports drinks, diluted fruit juice and water are suitable choices. For people exercising for more than 4 hours, up to 90 grams of carbohydrate per hour is recommended.
Carbohydrate foods and fluids should be consumed after exercise, particularly in the first one to 2 hours after exercise. While consuming sufficient total carbohydrate post-exercise is important, the type of carbohydrate source might also be important, particularly if a second training session or event will occur less than 8 hours later.
In these situations, athletes should choose carbohydrate sources with a high GI for example white bread, white rice, white potatoes in the first half hour or so after exercise. This should be continued until the normal meal pattern resumes.
Since most athletes develop a fluid deficit during exercise, replenishment of fluids post-exercise is also a very important consideration for optimal recovery.
It is recommended that athletes consume 1. Protein is an important part of a training diet and plays a key role in post-exercise recovery and repair. Protein needs are generally met and often exceeded by most athletes who consume sufficient energy in their diet.
The amount of protein recommended for sporting people is only slightly higher than that recommended for the general public. For athletes interested in increasing lean mass or muscle protein synthesis, consumption of a high-quality protein source such as whey protein or milk containing around 20 to 25 g protein in close proximity to exercise for example, within the period immediately to 2 hours after exercise may be beneficial.
As a general approach to achieving optimal protein intakes, it is suggested to space out protein intake fairly evenly over the course of a day, for instance around 25 to 30 g protein every 3 to 5 hours, including as part of regular meals.
There is currently a lack of evidence to show that protein supplements directly improve athletic performance. Therefore, for most athletes, additional protein supplements are unlikely to improve sport performance.
A well-planned diet will meet your vitamin and mineral needs. Supplements will only be of any benefit if your diet is inadequate or you have a diagnosed deficiency, such as an iron or calcium deficiency.
There is no evidence that extra doses of vitamins improve sporting performance. Nutritional supplements can be found in pill, tablet, capsule, powder or liquid form, and cover a broad range of products including:. Before using supplements, you should consider what else you can do to improve your sporting performance — diet, training and lifestyle changes are all more proven and cost effective ways to improve your performance.
Relatively few supplements that claim performance benefits are supported by sound scientific evidence. Use of vitamin and mineral supplements is also potentially dangerous. Water is probably the most important essential nutrient that a person needs.
A person can only survive a few days without consuming water. Even slight dehydration can cause headaches and impaired physical and mental functioning. The human body is made up of mostly water, and every cell requires water to function.
Water helps with several functions, including:. The best source for water is to drink natural, unsweetened water from the tap or bottled sources. For people who do not like the taste of plain water, they can add a squeeze of lemon or other citrus fruits.
People should avoid getting their water intake from sugary drinks. Sugary drinks include sweetened teas, coffees, soda, lemonade, and fruit juices. Find out how much water to drink to avoid dehydration.
A person needs to consume all six types of essential nutrients to ensure the best possible health. These nutrients support vital functions, including growth, the immune, the central nervous system , and preventing disease.
Typically, a person who eats a healthful, balanced diet that includes lean proteins, vegetables, fruits, complex carbohydrates, and water will get the nutrients they need. An individual should speak to their doctor about any medical conditions and the medications they are taking before they start to take any supplements.
Also, they may want to see a dietitian or nutritionist to discuss their nutritional intake before they begin taking any supplements. Read the article in Spanish. What are macronutrients?

Typically, the term "net carbs" is used to mean the amount of carbs in a product excluding fiber or excluding both fiber and sugar alcohols. You probably have also heard talk about the glycemic index. The glycemic index classifies carbohydrate-containing foods according to their potential to raise blood sugar levels. Weight-loss diets based on the glycemic index typically suggest limiting foods that are higher on the glycemic index. Foods with a relatively high glycemic index ranking include potatoes, white bread, and snack foods and desserts that have refined flours. Many healthy foods are naturally lower on the glycemic index. Examples include whole grains, legumes, vegetables, fruits and low-fat dairy products. So if you get 2, calories a day, between and 1, calories should be from carbohydrates. That translates to between and grams of carbs a day. You can find the carbohydrate content of packaged foods on the Nutrition Facts label. The label shows total carbohydrates — which can include fiber, total sugars and added sugars. Carbohydrates are the body's main fuel source. During digestion, sugars and starches are broken down into simple sugars. They're then absorbed into the bloodstream, where they're known as blood sugar blood glucose. From there, glucose enters the body's cells with the help of insulin. Glucose is used by the body for energy. Glucose fuels your activities — whether it's going for a jog or simply breathing and thinking. Extra glucose is stored in the liver, muscles and other cells for later use. Or extra glucose is converted to fat. Some evidence suggests that whole grains and dietary fiber from whole foods help lower your risk of heart disease and stroke. Fiber may also protect against obesity, colon and rectal cancers, and type 2 diabetes. Fiber is also essential for optimal digestive health. Evidence shows that eating plenty of fruit, vegetables and whole grains can help you control your weight. Their bulk and fiber content aids weight control by helping you feel full on fewer calories. Despite what proponents of low-carb diets claim, few studies show that a diet rich in healthy carbs leads to weight gain or obesity. Carbohydrates are an essential part of a healthy diet, and they provide many important nutrients. Still, not all carbs are equally good for you. So choose your carbohydrates wisely. Limit foods with added sugars and refined grains, such as sugary drinks, desserts and candy. These are high in calories but low in nutrition. Instead, select fruits, vegetables and whole grains.

It provides insulation to vital organs and works to maintain body temperature. Vitamins Regulate body processes and promote normal body-system functions. Minerals Regulate body processes, are necessary for proper cellular function, and comprise body tissue. Water Transports essential nutrients to all body parts, transports waste products for disposal, and aids with body temperature maintenance. macronutrients Nutrients that are needed in large amounts are called macronutrients. There are three classes of macronutrients: carbohydrates, lipids, and proteins. These can be metabolically processed into cellular energy. The energy from macronutrients comes from their chemical bonds. This chemical energy is converted into cellular energy used to perform work, allowing our bodies to conduct their basic functions. A unit of measurement of food energy is the calorie. A kilocalorie Calorie is the amount of heat generated by a particular macronutrient that raises the temperature of 1 kilogram of water 1 degree Celsius. Water is also a macronutrient in the sense that you require a large amount of it, but unlike the other macronutrients, it does not provide calories. Carbohydrates are molecules composed of carbon, hydrogen, and oxygen. The major food sources of carbohydrates are grains, milk, fruits, and starchy vegetables, like potatoes. Non-starchy vegetables also contain carbohydrates but in lesser quantities. Carbohydrates are broadly classified into two forms based on their chemical structure: simple carbohydrates, simple sugars, and complex carbohydrates. Simple carbohydrates consist of one or two basic units. Examples of simple sugars include sucrose, the type of sugar you would have in a bowl on the breakfast table, and glucose, the type of sugar that circulates in your blood. Complex carbohydrates are long chains of simple sugars that can be unbranched or branched. During digestion, the body breaks down digestible complex carbohydrates into simple sugars, mostly glucose. Glucose is then transported to all our cells, stored, used to make energy, or used to build macromolecules. Fiber is also a complex carbohydrate, but digestive enzymes cannot break it down in the human intestine. As a result, it passes through the digestive tract undigested unless the bacteria that inhabit the colon or large intestine break it down. As mentioned, glucose can be stored in the body for future use. In humans, the storage molecule of carbohydrates is called glycogen, and in plants, it is known as starch. Glycogen and starch are complex carbohydrates. Proteins are macromolecules composed of chains of subunits called amino acids. Amino acids are simple subunits composed of carbon, oxygen, hydrogen, and nitrogen. Food sources of proteins include meats, dairy products, seafood, and various plant-based foods, most notably soy. Proteins provide structure to bones, muscles, and skin and play a role in conducting most of the chemical reactions that take place in the body. Scientists estimate that greater than one-hundred thousand different proteins exist within the human body. The genetic codes in DNA are basically protein recipes that determine the order in which 20 different amino acids are bound together to make thousands of specific proteins.
