[The Legend of Zelda] How do Gorons get their calories/calorie equivalent from rocks?

I get that they're made mostly of rock, with the small amounts of non biogeological matter coming from hot springs mineral water, but how do they get energy from the rocks?

Their digestive tract is different.  You might as well ask a Goron how Hyleans get their calories from plants and meat.  Rocks contain plenty of energy if you can break them down properly.  Gorons can.
