I'm quite partial to Sandies shortbread cookies with pecan and vanilla. I suppose they just about count as junk food. Most of the ingredients look harmless enough but they probably contain too much sugar and fat. I often eat 8 in a day, so that's half the daily value for fat and about the same for carbohydrate. And I don't suppose the sugar does my teeth much good.
I also eat a few Great Value multigrain crackers and Saltine crackers (unsalted tops variety). Not enough to do me much harm, but with the Sandies it all adds up.
Beyond those vices, no junk food at all. I prepare everything else myself from basic simple ingredients. Last time I looked, my daily nutrient, vitamin, mineral and fibre intake seemed healthy enough, but that was before I got addicted to the Sandies and crackers. I don't like most junk food so I have to search quite hard to find any that I do like. I don't know how people can eat and drink a lot of the crap that gets sold. Still, they say you like what you're used to.
