Nutrient Sources Important for:


KEY CONCEPTCells require many different nutrients.


The six types of nutrients are water, carbohydrates, proteins, fats, minerals, and vitamins.

• Water makes up 55% to 60% of your body. – involved in nearly every cell and body process– need 2 liters (8 cups) a day to replace fluid lost


• Carbohydrates are the main source of energy for the body.– simple and complex carbohydrates supply glucose– fiber from plant foods helps elimination

Simple and Complex Carbohydrates


• Proteins are necessary for growth and repair of the body’s cells.– body makes 12 out of 20 amino

acids – other eight essential amino acids

come from food• Fats provide energy and key

building components.– fats are saturated and

unsaturated – essential fatty acids come from

food

Proteins and Fats


Meeting nutritional needs supports good health.

• During puberty, you require more nutrients and Calories.– One Calorie equals one

kilocalorie, or 1000 calories. – 1g of protein or carbohydrate

equals 4 Calories. – 1g of fat equals 9 Calories.


• Minerals are inorganic materials.– help to build or repair tissues– replenished by eating variety of foods


• Vitamins are organic molecules that work with enzymes.– vitamins are fat-soluble and water-soluble – regulate cell functions, growth, development – replenished by eating variety of foods

• Diet- the type of food eaten each day. Needs to be balanced.


• Fat- high energy food that contain twice as much energy as equal amounts of carbohydrates. One of the three basic food types. High in calories and can lead to weight gain.

• Protein-a naturally occurring substance made of amino acids found in animal products, and some plant products. Nuts, meats, fish, egg whites, grains


• Saturated fats-fats that are solid at room temperature, Some raise cholesterol level. Ex. butter, vegetable shortening, margarine.

• Trans fats- created by turning unsaturated fats into saturated fats in a process called hydrogenation. All raise cholesterol levels

• Unsaturated fats- fats that are liquid at room temp. (vegetable oils, olive oil, peanut oil). Tend to decrease a person’s cholesterol level.


• Cholesterol-a waxy food substance produced by the liver and found in animal sources. Too much clogs arteries.

• Trans fats-created by turning unsaturated fats into saturated fats through a process called hydrogenation


Calories and Metabolism
