Yes. On the Nutrition Tracker page of the website, scroll down to the "Tools & Settings" section. Click on "Remove Multiple Foods". You will then get another window where you can select multiple foods (or check one box to select all foods or all foods for a specific meal) to delete.
Hope that helps!
