NUTRIENTS

• Carbohydrates●Are the body’s main source of

energy.●An important and unique example is

dietary fibre . It is a mixture of plant materials that is not broken down in the digestive system.

●All forms of carbohydrates, except fibre, provide energy .

●Examples: Sugar, and starch.

SIMPLE CARBOHYDRATES

• Are a natural part of many foods.• Also provides other nutrients such as

proteins, vitamins, and minerals.• Includes:

● Fructose found in fruits● Maltose found in grain products●Lactose found in milk products●Sucrose found in plants such as

sugar cane or sugar beets. Do not supply nutrients other than simple carbohydrates.

COMPLEX CARBOHYDRATES

• Are broken into two categories: dietary fibre and starches.

• Found in legumes, lentils, peas, potatoes, pasta, rice, breads, and corn.

FIBRE

• Insoluble Fibre●Will not dissolve in water.●Absorbs water and helps to move

food through the large intestine at a normal rate.

●Promotes regular bowel movements and prevents constipation.

●Lowers the risk of colon cancer.●Found in fruit and vegetable skins

and in whole wheat or bran products.

FIBRE

• Soluble Fibre●Dissolves in water.● Increases the thickness of the

stomach contents.●May reduce blood cholesterol levels.●Found in fruits, vegetables, legumes,

peas, lentils, and oat products.

NUTRIENTS

• Fat●Are a reserve supply of energy

and act as a cushion to protect your heart, liver and other vital organs.

●Promote healthy skin and normal cell growth.

●Carries vitamins A, D, E, and K to wherever they are needed.

CHOLESTEROL

• Is not a fat.• It is a fat-like substance present in all

body cells.• Needed for many essential body

processes.• Contributes to the digestion of fat and

the skin’s production of vitamin D.• Adults manufacture all the required

amount in the liver.• Transported by lipoproteins (LDL and

HDL).

CHOLESTEROL

• LDL

●Moves cholesterol from the liver to wherever it is needed by the body.

●Too much can lead to a build-up on artery walls. Therefore heart disease and stroke.

• HDL

●Picks up excess and returns it to the liver, to prevent harm.

NUTRIENTS

• Protein●Are nutrients that help build,

repair, and maintain body tissues.

●Also are a source of energy.●Examples: Complete and

incomplete

PROTEIN

• Complete proteins●Supply all nine essential amino acids

include meat, poultry, fish, eggs, milk products, and soy products.

●Most Canadians get the largest amount of their protein from animal sources.

●Health experts recommend that people get more of their protein from plant sources due to the fact they have less fat.

PROTEIN

• Incomplete proteins●All foods from plant sources supply

incomplete proteins (exception soybeans).

● Incomplete proteins are lacking one or more essential amino acids.
