Calories
 Calories: number of calories in 1 serving
 Calories provide a measure of how much energy you get
from a serving of the food.
 The General Guide to Calories provides a general
reference for calories when you look at a Nutrition Facts
label. This guide is based on a 2,000 calorie diet.
Look at Fat, Cholesterol,

saturated fat, trans fat,
cholesterol, or sodium
may increase your risk of
certain chronic diseases,
like heart disease, some
cancers, or high blood
pressure.

running, playing an instrument, even sleeping.
 You need energy to maintain your body temperature
and keep your heart beating
 Energy nutrients provide calories
 Energy nutrients include carbohydrates, proteins
and fats
 Calorie: unit for the amount of energy released
when nutrients are broken down
Energy Nutrients:
Carbohydrates
Recommended daily intake: 45-65% of
daily calories
 Two Types:
 Simple
 Complex
Simple & Complex
Carbohydrates
 Simple Carbohydrates
 Sugars that naturally occur in fruits, vegetables and
milk
 Added sugars to manufactured foods such as
cookies, candies, soft drinks
 Complex Carbohydrates
 Starches, found in plant foods, such as potatoes,
grains, rice, oats, corn, and wheat products
 Complex carbohydrates take longer for your body to
metabolize than simple carbohydrates

 Fiber: a type of complex carbohydrate that can
not be broken down by the body
 Fiber passes through your body without being
digested
 Benefits of a high fiber diet include
 Helps prevent constipation
 May reduce risk of colon cancer
 May help prevent heart disease
 Fiber is found in whole grain breads and
cereals, vegetables, fruits, nuts, beans and
seeds
Fats
 Fats supply your body with energy, form
your cells, maintain body temperature,
and protect your nerves.
 Recommended Daily Intake 20-35% of
daily calories
Fats
