A better description would be "lactase treated" milk.
In any case, I found consuming it regularly for breakfast still lead me to feel unwell over time.
However I can periodically consume dairy when I take a strong dose of lactase supplements.
From some literature it does appear that manufacturers can use "lactose free" even for non-zero amounts of lactose (10mg per 100g).
This is actually higher lactose density than many cheese varieties, especially considering I would be consuming say 150-200g of yogurt, whereas if I am eating cheese its in small careful quantity.
Its a reference to the previous comment's 'specially engineered cows' quip - these cows do exist and produce a milk that is easier to digest (but still contains lactose).
Yes. I can find everywhere on labels the carb amount. I use 2 app too. And after a lot of errors I acquired a six sense (that try to kill me everyday ;-D)
