This is meant to be a fun topic about foods you enjoy(ed) but wouldn't go near now. There are other threads about current guilty pleasures - but this is about food that's just too hard for your "grown-up" gut to handle.
Some of mine:
-International Coffees (the General Foods powder mix - loved it when I was 20!)
-huge servings of red licorice
-meals with no fruit or vegetables
-rock hard, cigarette smoke infused muffins at the doughnut shop (ugh...)
