Lesson 1 “Carbs, Fats, and Proteins”Pages 155-161

What is nutrition?Nutrition is the science or study of food and

the ways in which the body uses food.Nutrients are substances in food that provide

energy or help form body tissues and are necessary for life and growth.

What are the six classes of nutrients?Carbohydrates, fats, proteins, vitamins,

minerals, and waterMake sure to eat a balanced diet!

All about carbohydrates…What are the two types of carbohydrates?

Why do we need carbs?

-Provides major source of energy to the body- Essential for digestion (fiber)- May help prevent certain cancers and heart disease

All about fats or lipids or triglycerides… Why do we need fat?-Cushions your body’s

organs -Helps keep your body’s

temperature under control

- Need to make hormones

- Forms coating on nerves

-Makes food taste better

All about proteins… Proteins are made up of chains of molecules called

amino acidsTwenty different amino acids make up the body

9 of the amino acids cannot be made by our bodies (essential amino acids)

Protein comes from both animal and plant foodsAnimal proteins contain all the essential amino acids

so animal proteins are called complete proteinsMost plant proteins have smaller amounts of some of

the essential amino acids so these proteins are called incomplete proteins

You must have all the essential amino acids to be healthy

Why do we need proteins?

-Your muscles, skin, hair and nails are mostly made up of protein - Makes hormones-Makes enzymes- Makes antibodies

Identifying Proteins, Fats and Carbs activityGet out a piece of paper

and number it to 10You will see a food on the

following 10 slidesIf you think a food is more

than one nutrient group, you might be right!

It is your task to label it correctly using the following key
