1. We Are What We Eat: Food Labels and Nutrition

2. Macromolecules Macromolecules make up all the food we consume!
Carbohydrates
Lipids
Proteins
These macromolecules give us energy to live!

3. How do we get energy?
The food we consume give us energy in the form of Calories.
Calorie: the quantity of heat required to raise the temperature of 1 gram of water by 1°C
Remember: heat=energy

4. Food Labels
All manufactured foods are required by law to have a food label.
What information can we get from a food label?
Total calories in the food
How much Fat, carbohydrates and protein the food contains
Essential vitamins
Daily percent

5. Using Food Labels
Each macromolecule provides our bodies with a certain amount of calories.
Carbohydrates: 4 calories per gram
Protein: 4 calories per gram
Fats: 9 calories per gram
We can use these values to calculate the breakdown of calories!

6. How?
You multiply the number of grams by the amount of calories it provides.
Add them together to get the total amount of calories for the food your eating.

7. Carbohydrates Total Carbohydrates: 19.66 grams
Calories provided: 4 per gram
19.66 X 4 = Calories

8. Fats Total Fat: 0.56 grams Calories provided: 9 per gram
0.56 X 9 = 8.64 Calories

9. Proteins Total Protein: 1.24 grams Calories provided: 4 per gram
1.24 X 4 = 4.96 Calories
