I love Perfect Bars (the blueberry cashew is my favorite) — they can be found in the refrigerated section, but are fine out of the fridge for a week before eating them. I used to be an RX Bar person, but when I was opening my business I had WAY too many of them and haven't been able to look at them since. If I'm at the airport or something, I'll try to find the Dark Chocolate Nuts & Sea Salt KIND bar, which are fairly easy to come by (in California at least)!
Well - I'm not really a bar person - I make my own trail mix and carry a big bag (literally - lol) around with me. I add raw pepitos, pistachios, almonds, cacao chips and sometimes I throw in some dried apple slices or cranberries - I just eat a handful or two!! My husband loves that I bring it when we travel - it's our go-to. BUT - I do always get stopped by TSA - they want to look at what's in the bag and then I start a healthy eating conversation - LOL!! ***Disclaimer - if I do buy a bar it's the RX Bar or low sugar Kind Bar.
Unpopular nutrition opinion: I think the healthiest bar is the one that 1) you like! 2) is affordable for you and 3) meets *your* needs! Processed food gets a bad rep, but honestly, it's a subjective term -- there's no one way that folx think about what is or isn't "processed". /end rant. 😉
That said! A few bars that either I enjoy and/or will recommend to clients (based on their needs/preferences):
The only thing I'd recommend steering clear of, or not having as often, is an artificially sweetened bar. No shame in the carb game, but more importantly, I think the taste is really unsatisfying. 😉
