Goal:

Understand nutritional labels and compare the nutritional value of different foods

Macronutrient Facts:

Macronutrients are the main nutrients that make up the food we eat:

Fats → Break down to fatty acids

provides the most energy per gram and are needed for cells to work and grow

Stored in cells to provide energy between meals

Proteins → Break down to amino acids

provides energy and are needed for cells to work and grow

Carbohydrates: Starches → break down to Sugars

Sugars provide quick energy

Too much sugar at a time can cause major health problems

Fiber can’t be broken down, but helps slow the absorption of sugars

1: Find out which foods have fat (and how much protein, carbs, sugar)

Record the amount of calories, fat, proteins and carbohydrates for the following:

Copper Canyon - 4 common foods

⁠

Corn⁠

(White Corn Flour - Masa) Change the serving size to 1 oz

⁠

Squash⁠

⁠

Beans⁠

⁠

Lard⁠

⁠

SAD - 4 common foods

⁠

Snacks/Desserts⁠

⁠

Bread⁠

⁠

Chicken⁠

⁠

Sprite⁠

⁠

Optional Extra: Use atom models to build nutrient molecules

Fatty Acids (shortest ones) - Use the order of elements written below as a guide

⁠

HCOOH

CH3COOH

CH3CH2COOH

Can you link three to make a fat?

⁠
⁠
⁠

Amino Acids - use the pictures as a guide and then write the formula.

⁠

Sugars - use the picture as a guide and then write the formula

2. Start setting up our circulation game

Put your names on the top sheet

Label the lungs, heart, kidneys and femur

Shade arteries, going away from the heart bright red

Shade veins, going toward the heart dark red
