Recommended Daily Intakes
How much (of what) do you need?
CAUTION
• Do not get hung up on numbers! People have different body types, metabolisms, and activity levels.
• Obsessing about calories can be harmful, and may sometimes lead to unhealthy eating patterns and psychological distress.
There are guidelines….
• It is wise, however, to follow some guidelines about how much nutrition you need in a day.
• Learning about which nutrients your body needs to function and grow will help you make good foodchoices.
CaloriesA calorie is a unit of measurement — but it doesn't
measure weight or length
A calorie is a unit of heat energy. When you hear something contains 100 calories, it's a way of describing how much energy your body could get from eating or drinking it.
Most teens don't have to worry about not getting enough calories because the body — and feelings of hunger — help regulate how many calories a person eats.

Calorie Intake Again: Individual calories needs vary according to size and
activity level.
• Girls aged 14 to 18 need between 1,800 and 2,400 calories daily.
• Boys aged 14 to 18 need 2,000 to 3,200 calories daily.
• Teenagers who are inactive will need fewer calories, and would usually stay within the lower ranges.
• Teenagers who participate in sports, high-intensity activities, or manual labour will need to maintain a caloric intake in the higher ranges.
Dietary Reference Intakes• Health Canada, along with U.S partners, issue nutrient
recommendations based on the latest information. These are called Dietary Reference Intakes (DRI).
• Recommended Dietary Allowance (RDA) is the average daily dietary intake of a nutrient that is sufficient to meet the requirement of nearly all (97-98%) healthy persons. This is the number to be used as a goal for individuals.
• The % Daily Value (% DV) can help you make informed food choices. Look for it in the Nutrition Facts table on food packages.
Keep in mind: 5% is a little, 15% is a lot

ASSIGNMENT• Create a day’s worth of meals from one of the three
nutrition guides located on your desk. • The meals are intended for yourself. So, if you are a 15
year old male who is very active, you would follow the caloric recommendations specific to that demographic (see notes).
• Compare your meals to those your group members came up with. Of the three restaurants, which do you think has the most nutritional value? Why? Discuss.
• Pass in the following:– A breakdown of each meal (items, calories, nutrients)– A total calorie count and a total nutrient count (represented by
DV%)
