Was this article written by someone who is lactose intolerant? I feel I should add these points as when I first found out I was lactose intolerant I would have been really sad to read this article as it skips some important cheese-related things!! 1- If you are lactose intolerant you can eat yoghurt which is greek style/natural/bio as the bacteria in it produces lactase (which digests the lactose).
2- Often people who are intolerant to cow’s milk can tolerate some sheep or goats milk and their derivatives. Therefore cheese can be had!
3- Hard cheeses contain less lactose than soft cheeses, or cream or milk. So many lactose intolerant people can have some cheeses. (the wiki page on lactose intolerance has a useful table on this)
4- Sodium caseinate is a protein and does not contain lactose so it’s safe for lactose intolerant people.
5- In the UK and Europe you can buy lactose-free milk (it has lactase added) and other lactose free products.
