That's sort of a 'how long is a piece of string' question.... Just because it does not say sugar does not mean there is no added sugar as there are dozens of other names for sugar iyswim. Also it depends on how the fruit is packed - packed in water, syrup, juice, own juices, etc. Different things are better/worse. So I would look for a product that has been packed in own juices or in water, with nothing else at all added.
