Glossary - Nutritional Terms
Calorie
A calorie is a basic unit used to measure the energy contained in food. More specifically, it is
the amount of energy needed to raise the temperature of 1 litre of water by 1 degree
Celsius. When you eat food, you are consuming the energy that is stored within the protein,
carbohydrate and fat molecules of that food.
1 Calorie = 1 kilocalorie = 1,000 calories = 4.184 kilojoules = 4,184 joules
Salt
Salt contains sodium, a naturally occurring mineral needed by the body to maintain life.
Sodium occurs in many forms such as sodium chloride (table salt), sodium bicarbonate
(baking soda) and monosodium glutamate (MSG). Sodium is especially important in the diet
because of its effect in conserving water. Certain foods are naturally higher in sodium, such
as celery, buttermilk, and some cheeses. Others, like canned or processed foods, have
higher levels due to the salt added in processing. High intakes of dietary salt may contribute
to high blood pressure or to your body retaining too much water.
Protein
Protein contains complex chains of amino acids necessary for conducting a variety of body
functions, such as building tissues, making important body chemicals
(e.g. enzymes and hormones) and maintaining growth and repair processes. While many
plant-based foods contain some protein, including beans, peas, vegetables, nuts and seeds,
these foods do not contain all the essential amino acids. Other protein sources from
animals such as meat, fish, poultry, eggs, and dairy products (milk, cheese and yogurt) are
considered higher in protein content since they contain all essential amino acids. Each gram
of protein provides four calories of energy.
Fat
Fats occur naturally in foods and play an important role in nutrition. Fats, oils and some
foods like nuts (e.g., peanuts, walnuts and almonds) are a concentrated source of energy for
the body. Fats store energy in the body, protect tissues and transport fat-soluble vitamins in
the blood. Fat is found in meats, fish, and meat substitutes, breads, starches and some dairy
products. Fat supplies nine calories per gram, twice as many as protein or carbohydrate.
Carbohydrate
Carbohydrates are the body's primary source of readily available energy. The main forms of
carbohydrate are sugars and starches. Sources of simple carbohydrates include table sugar,
candy and refined flour products. Complex carbohydrates include starches like oatmeal,
high fibre cereals and whole wheat flour products. Together simple and complex sugars are
broken down in the body into glucose. Glucose is the preferred type of energy used by vital
organs and, especially, the brain. Each gram of carbohydrate provides four calories of
energy.
Sugar alcohol is a type of carbohydrate that is used to sweeten foods and can come from
natural and manufactured sources. They include sorbitol, mannitol and glycerol found
when a small range of foods including fruit and vegetables, snack bars and confectionery
were analysed.
