House Foods Shirataki noodles?

Hi everyone, came by with a quick question!

So, here at my Staterbros I pick up these Shirataki noodles time to time, mainly cause they're pretty cheap compared to the miracle noodles that are the other option, and just whenever I have a little noodle fixation.

But is this thing really 0 calories? Because I can't really seem to believe it. And it makes it a little difficult to log not knowing the true value.

I'm not sure what product in the case of it not being 0 calories to compare to either when logging, so maybe some insight on what you guys think is best may be helpful. Thanks!
