No idea! I think the Tesco thing was last year and they are in to British Heart Foundation now? We’ve only got tiny Tesco’s near us so we almost never use them. That plain low fat yoghurt seems weird though doesn’t it, alongside the others.
This Tesco one seems more standard:

7g per 100g.
The other one you found is a mystery!
When you originally brought it up, and asked Hannah about how low fat (with extra carbs) fit into the newer low carb suggestion from DUK, I may have misunderstood, but I thought you said you had compared various products in the past and found several to be problematically loaded with carbs. I’ve seen that mentioned by several people over the years, but I’ve not seen any actual examples - I was just intrigued as to what you’d found when you looked.
