My sister's friend died from it.
The man was at a BBQ where he asked if any peanut oil was used in the BBQ sauce. The cook said no. It turned out otherwise.
Folks with nut allergies have the same obligation diabetics have ~ namely, READ THE LABELS. And if there are no labels, don't take the risk!
I read every label. If it says as much as 2g carbohydrates per "serving", I don't eat it!
