This is a really great app recommended by health educators. Frequently MyFitnessPal is used for tracking food in health lessons, this app is honestly easier to use. I always remind students that while these applications can help guide you to lose weight you should always talk to a doctor before planning any major life changes.
While this is on a website that sells lesson plans, this one is free. I really like the PowerPoint that is with this lesson for when I teach this lesson in the classroom rather than having students read about nutrition labels.
I use this worksheet with general guiding questions to help students really see the differences between different foods based on their nutrition labels. This is a fun in class group activity for them to see examples of nutrition labels before they go home and start looking in their own pantry.
This is something new I recently found to integrate into my lesson on nutrition labels. I will probably use it as a supplemental resource alongside the Reading Nutrition Labels PDF and the Nutrition Facts Label video for students who want the content outlined in the infographic format.
This is an excellent concise resource that describes how to read nutrition labels. This, pared with one of the videos on reading nutrition labels is often more than enough for high school students to be ready to jump in and apply these concepts.
