Too much fat in soya milk?

i've just started using soya milk, for all the goodness of it, reducing cholesterol etc. i know there are many different types, but either with loads of sweeteners and additives, or too much fat. tried another one today: i read the label, it contains water, 5% hulled soya beans and natural flavourings, nothing else.1 liter contains 17 grams (!)(not mg) of fat though.how can that be? where does that fat come from?doesnt sound too good, does it? and it wasn't even cheap cr*p either. any ideas on that?
