What is Nutrition ?

Nutrition is the science which looks at food , the nutrients they contain and the impact they have for overall health and growth.

How does the body use protein?

• Growth

• Muscle Development

• Chemical reactions involving Enzymes

• Provide body structure ; hair , nails, skin

How does the body use fats?

• Warmth

• Protects Organs

• Dissolve nutrients such as Vitamins

• Provides Energy

How does the body uses Vitamins/Minerals

• Teeth

• Bones

• Helps Immune System

​

ENERGY

How is the energy consumed in food used?

• 10% of the energy used by the body is used to digest and process (oxidize) food

• 20% of the energy used by the body for physical activities

• 70 % of the energy from the food we consume is used for BMR

What is BMR?

• BMR stands for Base Metabolic Rate

• This is the Energy needed to maintain Life when at rest

• Breathing , heart beating ,cell production, healing

• The term metabolism is used to describes the set of chemical reactions involved in storing fuel (food) molecules and converting fuel (food) molecules into energy

BMR differs according to

• Gender :generally, men have faster metabolisms because they tend to be larger

• Height

• Weight : larger adult bodies have more metabolising tissue and a larger BMR. 

• Age : metabolism slows with age due to loss of muscle tissue

• Higher BMR is the more calories will be burned

• Muscles burn more calories

Multiple Choice

What percent of the energy we consume we use for physical activity ?

• 10%

• 20%

• 60%

• 90%

Multiple Choice

What percent of the energy we consume we use for digestion ?

• 10%

• 30%

• 60%

• 90%

Multiple Choice

What percent of the energy we consume we use for BMR ?

• 10%

• 30%

• 70%

• 90%

Multiple Choice

What is metabolism?

• A condition that occurs if the person does not get enough iron in their diets

• They supply energy for your body's functions

• Supplies your body with energy

• The rate at which you burn calories while at rest

Multiple Choice

This is the rate at which a person uses energy when the body is at rest.

• Basal Metabolism

• BMI

• Calories

• Fiber

Multiple Choice

The measurement for the amount of energy released from food is called ......

• Fiber

• Fat

• Carbohydrates

• KCalories

Multiple Choice

The measure of energy in food is:

• fiber.

• nutrients.

• calories.

• BMR.

Multiple Choice

Which of the following does not affect BMR?

• Age

• Weight

• IQ

• Gender

• The amount of each of the nutrients that we need to consume will vary from individual to individual

Open Ended

Who do you believe would require more calories , a teenager or an 50 year old adult ? Give reason for you answer

Teenagers

• As teenagers you are still growing and developing

• More food energy must be consumed beyond that required for BMR or Physical activities

• Insufficient Energy will retard growth and development

At Your Table discuss the following questions

• How do you believe the energy requirement would differ between a middle schooler who play sports and one who does not?

• What do you believe would happen to a person who is not very active and consume too much carbohydrate, protein or fat?

• If one consumes more calories than the body uses, the excess is stored and weight is gained.

• Weight loss occurs when fewer calories are taken in than the body needs.

• Fats, protein and Carbohydrate when not burned will be stored as fat

• In order for energy balance to occur, Energy In = Energy Out.

• This means that caloric intake equals caloric output

Open Ended

What will happen if more calories are taken in other than what meet BMR requirement , that for exercise and body processes?

Having a Balanced Diet

Problems with not having balanced diet

• High Cholesterol

• Diabetes

• Poor Growth

Open Ended

What are some things that we can do to ensure that Caloric intake is equal to caloric output ?

Reducing Caloric Intake
