                                According to the Heart and Stroke Foundation of Canada, canned tuna is indeed classified as a processed food, but not an ultra-processed one. The key distinction lies in the level of alteration and added ingredients, which shows that not all processing is created equal and that a food can be processed while still being a healthy part of a balanced diet.
