the human organism and the importance of nutrition
DESCRIPTION
The Human Organism and the importance of Nutrition. Ch 6. Black = Notes Red = Just read/discuss or write it if you need it. WHAT DO YOU KNOW ABOUT NUTRITION?. Food and its use by the body. Follow along in workbook pg. 89. Food. any substance ingested that sustains life. - PowerPoint PPT PresentationTRANSCRIPT
SYSTEMS THAT WORK WITH NUTRITION
Digestive system= breakdown food nutrients Respiratory system = bring in oxygen to burn
nutrients Cardiovascular system = carries nutrients and
oxygen to cells Urinary system = discard wastes
FOOD IS BROKEN INTO CLASSES OF NUTRIENTS
Nutrients are essential dietary factors used by the body to meet important needs.
There are 6 main groups.
DETECT PROTEINS LAB #44Dwayne Johnson, “The
Rock”, sidelines in cat rescue.
He needs to learn how to find out which drink would give him the most proteins to help his muscles.
CARBOHYDRATE SOURCESPolysaccharides (Starch)
(longer to digest) -in grains, vegetables, legumes
Monosaccharides (Sugars)(faster to digest) - in pop, candy, sweets,
fruit
EXPLAIN THE TREND AND SUGGEST WHY IT IS HAPPENING.

FAT SOURCES Dairy products (milks, butter), veg. oils, fatty
meats/fish, deep fried food, eggs, nuts
DETECT FAT LAB #43 Jennifer Hudson is on a
low fat diet since winning “American Idol”
She needs to learn how to detect fats in her foods so that she can monitor how much fat she is consuming in a day.
LIST WAYS THAT YOU CAN REDUCE YOUR FAT CONSUMPTION
Low fat cooking methodsMinimize processed foodsUse better cuts of meatsUse low fat alternativesDecrease use of condimentsWhite rather than red meat
WATER FUNCTIONSTransports nutrients and wasteRegulates body temperatureEssential for chemical reactions
VITAMIN FUNCTIONSHelp with chemical reactionsHelp with E productionHelp fight off infectionsRepair damaged tissue
MINERAL FUNCTIONS
Building tissues (bones and teeth)Maintaining fluid balanceHelping muscles contractTransport Oxygen (O2) in the blood
MINERAL SOURCES
Dairy products, legumes, seafood and fish, fruits, vegetables
e.g. Calcium, Potassium, Sodium, Phosphorus, Iron
DETECT CALCIUM AND VITAMIN C LAB #45 & 47
Ellen DeGeneres just landed a contract promoting vitamin drinks for big money.
She needs to learn how to detect calcium and vitamin C in her drinks so that she knows which products to promote.
teen girls =7 200- 9 600 kJ of E per day (1800-2400 calories)teen boys =8 800- 12 800 kJ of E per day (2200-3200 calories)
ALL-BRAN ANYONE?
Fibre = from complex carbohydrates, fruits and vegetables
can’t digest it cleans out intestines (this helps to prevent
cancer)
HOW CAN YOU GET MORE FIBRE INTO YOUR DIET?
white flour whole wheat flour e.g. Pasta, bread
Don’t peel vegetables (most fibre is in the skins e.g. Potatoes)
breakfast cereals less refined kinds ( Froot loops (notice the spelling of fruit = no fruit at all) to muesli or granolas)
NUTRITION LABEL
Gives nutritional information contained in one serving of a product
in grams and % RDI (Recommended Daily Intake)
NUTRITION LABEL LOOKS LIKE THIS
Size of recommended portion
Number of servings per package
Calories per serving
Amount of nutrients by weight and % of RDI
% of RDI for vitamins
FOOD LABEL ACTIVITY
Go to the food package stations and collect information from the food labels onto your chart.
DO NOT MOVE THE FOOD PACKAGESWe will discuss the results on the board.
CANADA’S FOOD GUIDE
If Canadians can be taught to eat healthy foods and exercise mildly, it will reduce the strain on the Socialist Health Care System that is in place (Medicare)
