Great tip from Redditor Dibblah “I have read that hard cheeses can be ok – if you read the labels and they have 0g sugar, that means no lactose so they ought to be fine.”
So I looked into it and it does seem to be true! If you want to know if a cheese is lactose free then you need to check the nutritional label and see how much sugar is listed. Lactose is a sugar so if it has none – then it has no lactose either. Legally it can have up to half a gram of sugar and still be “Sugar Free” so it will depend on your tolerance it may also say “trace”. If you can handle a little you should be fine. But in general it should be fine with most people. This is especially good if you need to know if a Feta Cheese or Halloumi Cheese contains lactose. A lot of goat’s cheeses are lower in lactose so this is a great way to check how little it contains.
As a guide – Most aged hard cheeses are more likely to be lactose free. Mozarella may also be lactose free too. – I can’t wait to get out there and see which cheeses don’t contain lactose!
One other word of warning I noticed around the web – if it doesn’t list the sugar content – don’t trust it.
Enjoy your new world of cheese!
