What is Nutrition?

Nutrition is essentially the nutrients we eat in order to fuel our body. The body cannot function without these nutrients. The nutrients that are consumed are turned into energy for the body to use. This energy is used for functions such as basic breathing, digestion, etc., but is also essential for our athletic activity.

Probably one of the most popular words associated with nutrition is diet. The actual definition of diet per Webster’s New World Dictionary is “ what a person or animal usually eats and drinks; daily fare”. When you examine this definition, diet is essentially the food and beverages a person consumes each day, hence why an athlete’s diet should consist of plenty of nutrients to fuel their peak athletic performance.

Everywhere we look there are new dieting gimmicks and supplements that promise increased energy, which translates into increased athletic performance. It is sometimes hard to discern what is proper nutrition for athletic performance and what are erroneous, unproven and harmful marketing techniques.

Through scientific studies we know there are six essential nutrients, carbohydrates, fats, protein, vitamins, minerals and water. The body will not function properly without all of the six nutrients. Finding a balance between all these nutrients will not only have a positive impact on your overall health, but also optimize your athletic performance. For instance, muscle cells are made up of 75% water and will not function efficiently if they are dehydrated. As these cells become dehydrated they induce cramping in the muscles and inhibit an athlete’s ability to perform. The Gatorade Sport Science Institute has proven that 1-2% dehydration can decrease one’s performance by 2-5%. This decrease in performance can be the difference between a win or loss.

Three of the essential nutrients carbohydrates, fats and proteins, are considered energy nutrients, meaning they contain calories that are converted into energy in the body. For more information on  these follow each of the links;
