Do sprats need to be gutted? Do you need to gut sprats before cooking &amp; eating them?

i.e.


is it safe to eat them (so long as they're cooked).
do they taste ok (to the average non-squeamish person happy with a bit of fish offal).


Research so far

I've searched online but can mostly find the question asked without answer, or with people stating that they've only had them gutted; but with no advice on whether ungutted is acceptable.

e.g. There's a recipe for Grilled Sprats about halfway down the page here where it's advised that you can eat the heads, but the recommendation to remove the guts and gills remains (gills so they don't get stuck in your teeth; guts aren't explained).  Since this chef is known for eating most things, I assume there's a good reason to avoid the guys; though perhaps he's tweaked his recipe for the paper's audience: http://www.theguardian.com/environment/2006/oct/07/features.food7
It is safe to consume the guts.
Many people do.


More Info:

After digging deeper into the above article I spotted it contains the answer.
http://www.theguardian.com/environment/2006/oct/07/features.food7


  They're so small (only up to 12cm long) that they're often cooked whole - head, guts and all. If you prefer, however, you can open up the belly with your thumb and rinse out the innards, and prise out the gills with your thumb and forefinger.


Regarding their association with brisling, it seems that the two terms are synonymous (though somewhat contextual):


  Sprats are sometimes also known by their Scandinavian name, brisling, especially if they've been smoked and canned.
