Diet: Everything that a person eats. A balanced and complete diet is based on the scientific principles that healthful foods and appropriate nutrients must be consumed each day.
Calorie/Calorie: One calorie is the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius. One Calorie, or kcal, is equal to 1,000 calories, the amount of energy required to raise 1 kilogram of water (about 2.2 pounds) 1 degree Celsius. Nutrition is measured in Calories.
Metabolism: The number of calories burned at any given moment. An individual’s basal metabolic rate (BMR) is a measure of the number of calories burned to keep the person’s heart, lungs, and muscles working while the body is at rest. An individual’s actual metabolism is higher when the person is active than it is when the person is at rest.
Nutrients: Substances found in foods that people need to stay healthy. Proteins, carbohydrates, vitamins, minerals, and fiber are essential elements of a nutritious diet. Proteins make the cells, while carbohydrates provide energy. Vitamins regulate chemical processes in which the body converts food into energy and tissues. Minerals such as calcium are essential for building strong bones and teeth. Fiber helps keep the digestive system functioning smoothly.
