UNIT 3: Carbohydrates - Macronutrients I

Overview (including Survey)

Seminar

DiscussionConsider how having diabetes could affect your life and how our eating habits affect risk for the disease.

Lesson 1Substitute healthier foods based on carbohydrate (simple vs. complex) 1-2 hrs.

Lesson 2Decide if daily intake meets recommended calorie percentage from carbohydrates 1-2 hrs.

Lesson 3Look up articles and summarize evidence that dietary fiber helps prevent disease 3-4 hrs.

12

UNIT 3: Lesson 1 Prepare

1. Substitute healthier foods based on carbohydrate (simple vs. complex)

On useful method for analyzing carbohydrate content in a food is to compute the percent of carbohydrate from sugars.

Step 1: Find the amount of sugarsStep 2: Find the amount of total carbohydrateStep 3: Divide sugars by total carbohydrateStep 4: Multiply by 100

The percent of carbohydrate from sugars will be a number between 0 and 100. •A higher number indicates a higher amount of simple carbohydrates. •A lower number indicates a higher amount of complex carbohydrate.

Percent of Carbohydrate from Sugars

If Percent of Carbohydrate from Sugars is… Then we would say the food is…

70 or greater

30 or lower

High in simple carbohydrates

High in complex carbohydrates

13

UNIT 3: Lesson 1 Practice (Item 1)

Simple

Complex

Classify each carbohydrate-source food as high in simple or complex carbohydrates. Compute the percentage of carbohydrate from sugars if needed.

You have volunteered to help with a Nutrition Fair at the local elementary school. Having been assigned to work in the Carbohydrates Booth, your job is to help people attending the fair identify foods high in simple and complex carbohydrates.

Is this food higher in simple or complex carbohydrates?

1. Substitute healthier foods based on carbohydrate (simple vs. complex)

Sample exercise

14

2 g sugar / 29 g carbohydrate = 0.0689

0.0689 x 100 = 6.9% (7%)

Less than 30% - Complex carbohydrate

15


2. Decide if daily intake meets recommended calorie percentage from carbohydrates

These steps can be used to compute the percent of calories from carbohydrates for a single food item, for a meal, or a daily intake.

Find the total amount of carbohydrates

If needed, convert grams of carbohydrate to calories by multiplying the total carbohydrate grams by 4

Divide the number of calories from carbohydrate by the number of total calories and multiply by 100

Find the number of total calories

UNIT 3: Lesson 2 Practice (Set 2)

Your friend has been tracking the foods she eats and wants your opinion. She tells you that her recommended daily calories is 2200, and yesterday she consumed 120 grams of carbohydrates.

Decide if your friend’s intake from yesterday meets the guidelines for percent of calories from carbohydrate.

2. Decide if daily intake meets recommended calorie percentage from carbohydrates

120 grams x 4 kcal per gram = 480 kcal from carbohydrate

480 / 2200 = 0.218

0.218 x 100 = 22 %

Answer

Is your friend’s diet from yesterday within the guidelines for percent of calories from carbohydrate?

Yes or No

17

What is the reason for your answer?

_____ Her percent of calories from carbohydrate is below 45%. _____ Her percent of calories from carbohydrate is between 45-65%

_____ Her percent of calories from carbohydrate is above 65%

UNIT 4 Preview: Fats - Macronutrients II

Overview

Seminar

DiscussionNo discussion in this unit.

Lesson 1Substitute healthier foods based on amount and type of fat content 1-2 hrs.

Lesson 2Decide if daily intake meets recommended calorie percentage from fats 1-2 hrs.

Lesson 3Analyze fat content and create a healthier diet plan within dietary guidelines for amount and type of fat 4-7 hrs.

23

UNIT 4 Preview: Lesson 1 Prepare

1. Substitute healthier foods based on amount and type of fat content

Because saturated and trans fats are the most likely types of fats to increase one’s risk of heart disease, professionals recommend reducing intake of saturated fats and keeping trans fat out of one’s diet as much as possible.

Saturated and Trans Fats

Healthier Foods: Lower Saturated FatFoods High in Saturated Fat

24

UNIT 4 Preview: Lesson 1 Practice (Set 1)


Rank order these snack chips by amount of saturated fat from least to most.

26


2. Decide if daily intake meets recommended calorie percentage from fats

NOTE: To convert the number from Step 3 to a percentage, multiply it by 100.)

This procedure can be used to compute the percent of calories from fat for a single food item, a meal, or a daily intake.

Computing Percent of Calories from Fat

Find the number of calories from fat

Divide the number of calories from fat by the number of total calories

STEP 1

Find the number of total caloriesSTEP 2

STEP 3

27


What percentage of calories are from fat?

2 grams of fat x 9 kcal per gram = 18 kcal from fat

18 / 157 total calories = 0.12

0.12 x 100 = 12% calories from fat

Maple & Brown Sugar Instant Oatmeal


28


Yes

No

Is your friend’s daily intake within the guidelines for percent of calories from fat?


Her percent of calories from fat is between 20-35%

Her percent of calories from fat is below 20%

Her percent of calories from fat is above 35%

A friend has been tracking her calorie intake and wants your help. She tells you that her recommended daily intake is 2000 calories, and yesterday she consumed 620 calories from fat.

Decide if your friend’s intake is within the guidelines for percent of calories from fat.
