First off, there are six classes of nutrients: carbohydrates, fat, protein, vitamins, minerals, and water. The energy-yielding nutrients are carbohydrates, fats, and protein. These nutrients provide the body with energy, such as doing work, moving or heating something. Most importantly, a Calorie, is the unit used to measure energy.
Carbohydrates, proteins, and fats yield out different amounts of calories.
Carbohydrates - 4 calories/gram
Protein - 4 calories/gram
Fat - 9 calories/gram
Alcohol - 7 calories/gram (nonessential nutrient)
Vitamins and Minerals
Don't provide calories, but are essential, regulates the release of energy from carbohydrates, fat and protein and are involved in many other metabolic activities.
Water
Provides the medium for life processes. Water keeps the body hydrated. Your body needs water to regulate body temperature and to provide the means for nutrients to travel to all your organs. Water also transports oxygen to your cells, removes waste, and protects your joints and organs.
Next time, I'll go over calories and what can be an ideal diet.
