I really like the Buy Better Groceries interactive graphic from the Washington Post.
It lets you choose from a variety of grocery sections. Then, you choose brand names from that product category. You’re then shown the different nutritional values of your choice, and you can compare that with other options. You can then fill-up a virtual grocery cart with your “purchases” and see a total nutritional information for everything you’ve “bought.”
It’s a great exercise for Intermediate English Language Learners to gain nutritional information and vocabulary development.
I’ve placed the link on my website under Food.
