I'm not sure if this is the right place to ask as this also related to science and health in a way, but here goes anyway. This is a bit on the long side, so feel free to skip right to the last paragraph if you don't feel like reading.

I stay away from dairy products and by-products, so I drink soymilk and other "milks". Last year I discovered I have a slight sensitivity to soy, which means if I eat too much of it I get bloated like you wouldn't believe.

Because of this I used to dose my intake of soymilk, like having a glass of it (cold) only once every two days or so, and everything was fine. Now recently I discovered the wonders of oatmeal (porridge), and I've been having it every morning (cooked with soymilk) for the last three weeks or so. And guess what, no bloating whatsoever.

Until a couple of days ago I decided to add some extra soymilk (cold) to my bowl and - you guessed it - I was bloated and feeling miserable the rest of the day.

So this got me wondering. Could the heat actually destroy/alter something in the soymilk thus making it more digestible? What say you, food experts?

Heat destroys/alters all food nutrients, vitamins and minerals.
You are probably better off with lactose intolerant milk
It could also be the type of soy. Natural soy is good for you but processed soy can lead to health problems in some.

Well, as far as I know this is good soy - no-gmo et al. Cow's milk wouldn't do for me, I really do not think anyone would be better off with it, lactose intolerant or not, to be honest. And as long as I don't eat soy for every meal it doesn't hurt me at all.
