If you are referring to oil slicks, that has happen to me when I eat something that really fatty like ox tails or something to that effect. Or if I had a lot of red sauce.
It's undigested fat that happens if you eat too much fat. For me cheese and ice cream are the usual culprits. I eat both everyday but I'd I OD, the oil slicks kick in.
I get that when I eat too much fat and also...red sauce
If you have a specific question for me, PM me or I will not see it, as I don't check responses on the forums and don't have anything forwarded to my email.
