Example of why counting calories is just a guessing game even if you are using the labels.
Here are 2 labels from Asia Farm Spinach that Costco sells. They used to sell 500g bags, but now they sell 1kg bags. Both frozen and packaged the same as far as I can tell.
The 500g bag showed 32 calories per 100g. The 1kg bag shows 17 calories per 100g.
