I know that Heinz soups are higher in sugars, but not sure on the cards. As an alternative, I have been using Morrisons own Classic brand of soups, as they are both lower in fat and sugars, and the carbs are not too high, compared to many other foods. I also find Morrisons soups just as good as Heinz.
Thanks to the people and messages on here, as long as you are not eating the same things on a constant basis, you will lower your sugars, it's about variation and seeing where you can use alternatives that are low carb as well as low sugar, something as simple as celery with a small dollop of philly garlic and herb cheese is such a nice alternative, just don't over do it with the Philly soft cheese, even though it's lower in carbs and sugars.
