When you are preparing to undertake a new fitness regimen and get stronger and healthier, having a solid understanding of the role of nutrition and diet may help you achieve your goals much faster. A healthy diet that contains adequate amounts of protein, carbohydrates and fat will promote muscle growth and development and also provide you with the energy you need to get through your workouts.

Asker E. Jeukendrup and Michael Gleeson highlighted the importance of understanding the six essential categories of nutrients in the book "Sport Nutrition: An Introduction to Energy Production and Performance". According to Jeukendrup and Gleeson, these nutrients are needed by the body to function optimally. They also stressed the significance of water, vitamins, and minerals in the body's performance levels.

The nutrients obtained from food help to provide energy, regulate the metabolism and promote healthy growth and development of muscle tissues and all cells in the body. Without the right nutrition program, you may be compromising your health and your performance levels. The six different categories of nutrients are defined as: carbohydrates, fats, proteins, vitamins, minerals and water. These are all necessary for providing the organs and muscles with enough energy to perform basic metabolic functions such as repairing damaged cells, protecting the organs and maintaining healthy blood circulation.

Protein is perhaps one of the most important components of any athlete's nutritional program because it helps build the cell structure throughout the human body. Without enough protein, your body will not be able to heal or repair itself properly after an intensive workout, and may resort to breaking down valuable muscle tissue just to perform all necessary functions. If you are involved in heavy weight lifting or other resistance exercises, you may need to increase your protein intake to ensure that your cells have enough energy to recover and repair themselves after any damage.

Water is another essential for every athlete or fitness enthusiast. About 60% of the body is made up of water, and the water content varies in different tissues of the body. Muscles are made up of about 75% water, while adipose tissue (fat) is just 5% water. Since it's very easy to become dehydrated after exercise, it's essential to drink water throughout the day, during and after a workout. Dehydration can result in confusion, disorientation, depression and excessive muscle fatigue.

Nutritional supplements with vitamins and minerals act in the development of healthy cells in the body. Said nutrients are typically found in different food groups. However, people cannot consume foods with all these nutrients in fresh vegetables, fruits, whole grains and protein all at the same time. Maintaining a healthy body requires getting all of these nutrients and the best way to do this is through a nutritional supplement.

Finally, looking carefully through food labels and keeping a food log can be a good way to enhance your nutrition and fitness programs. Energy is well maintained and your performance may reach its peak levels if you ensure a healthy diet containing all the six essential nutrients. Further, the body can have enough fuel to heal itself after rigid exercise routines.
