One of my kids is lactose intolerant.... then I discovered that milk powder is in SO many products as it's a cheap way to add a rich flavour to foods.

The net result is that through a genetic accident (the kid is half chinese half european and it's likely the intolerance comes from the chinese side) we all eat more healthily.

Referring to the article: When you have to be more careful about what you eat you tend to have to make more of your own food and, for me at least, the act of making food suppresses my appetite resulting in me eating less. I think this is because it effectively lengthens the time my brain is in 'eating' mode and it feels satiated after less food. I basically made that up though but I'm happy to live with that.

I wouldn't say I am any healthier but I have maintained my current level of unhealthiness with less food :)
