I’m lactose intolerant; gives me really bad IBS. Took ages to work out what it was that was causing it & was annoying cutting out lactose to start with, but don’t really miss it now.
Goat’s & Sheep’s milk are both fine, as is double or clotted cream (all fat, no sugar), most hard cheeses are fine in moderation, as is yoghurt & I use whey isolate powder at the gym rather than whey concentrate. I drink black tea, eat dark chocolate, religiously check ingredients if out for a meal & really miss lasagne.
Not experienced it stunting growth though. I’m 5’11” & my sister (who also has it) is 6′
