Cold Water

I've been reading a lot lately on the negative effects of cold water.  Now, most nutritional studies seem to just be poorly constructed data sets bent to find something 'interesting', but I think this one might hold water.  To main points:

1) Cold water may trigger your body to think that it is getting cold and you should store fat, thus slowing down your metabolism.
>Now, I'm not sure how much I buy that.  In many places, spring glacier runoff actually keeps water cold well into spring, and bodies of water take a long time to cool. I don't know that drinking cold water would be a signal of winter for your body.  But I thought it worth noting because you can see that water would cool toward winter in the majority of places. That may be enough to have an evolutionary effect.

 2) Cold water solidifies oils, grease and such from foods you've just eaten.  This makes the food harder to digest.  This added trouble to digest will cause the release of more acid, and still not all gets broken down properly. Well, there are a litany of problems involved, but you get the idea.

IMO, this is enough info to at least consider.
