Detailed Lesson Notes
Understanding Portion Sizes
Portion size is the amount of food served or eaten at one time. When eating out, especially at fast food restaurants, portion sizes can be larger than what is healthy. Large portions can lead to eating more calories than the body needs, which can cause weight gain and health problems. Teaching students to recognize appropriate portion sizes helps them make better food choices.
How to Determine Appropriate Portion Sizes
Students should learn to compare the portion sizes they are served to recommended serving sizes. For example, a healthy portion of meat is about the size of a deck of cards, and a serving of vegetables is about half a cup or the size of a fist. Using visual comparisons helps students estimate portion sizes when nutrition labels are not available.
Added Sugar and Its Health Effects
Added sugars are sugars added to foods and drinks during processing or preparation. Consuming too much added sugar can cause dental cavities because sugar feeds bacteria in the mouth that produce acids that harm teeth. Excess sugar also contributes to obesity by adding extra calories without nutrients. Students should learn to identify foods and drinks high in added sugars and understand why limiting sugar is important.
Making Healthy Choices at Fast Food Restaurants
Fast food meals often contain large portions and high amounts of added sugars. Students should practice choosing smaller portion sizes, selecting healthier side options like fruit or vegetables instead of fries, and drinking water instead of sugary drinks. Role-playing ordering meals can help students apply these skills.
Common Misconceptions
Some students may think that larger portions are always better or that fast food is always unhealthy. It's important to explain that portion size matters more than the place food is eaten and that some fast food options can be part of a healthy diet if chosen carefully. Another misconception is that sugar only affects teeth; explaining its role in overall health helps broaden understanding.
Worked Examples
Worked Example 1
Scenario
Look at this fast food menu item: a burger meal with large fries and a soda. The nutrition label shows the burger is two servings, fries are three servings, and the soda contains a high amount of added sugar. How can you choose a healthier meal with appropriate portion sizes and less sugar?
Explanation
The student should recognize that the burger and fries are larger than one serving each, so choosing a smaller burger or a single serving size is better. They should also choose a smaller side like a salad or fruit instead of large fries and select water or a low-sugar drink instead of soda. This reduces calorie intake and added sugar, supporting healthier eating.
Answer Guide
Choose a smaller burger or one serving size, replace large fries with a side salad or fruit, and choose water or a low-sugar drink instead of soda.
Engage
Teacher Activity
Begin by asking students if they have ever eaten at a fast food restaurant and what kinds of foods they ordered. Show pictures of different portion sizes of the same food and ask which looks like a healthy amount to eat.
