Something I’ve found useful on low-carb dieting is seaweed (Don’t Laugh!)
There are lots of seaweed ‘snacks’ out there now that satisfy the desire to crunch something a little salty; and the good ones are healthy, low-carb, and very nutritious. They are full of minerals, as well as B-12, important to us as we get older.
My favorite has always been dulse; but lately I’ve been enjoying some of the Nori snacks. Like anything, don’t overdo it - it’s not something you want to eat a lot of. I use it like the occasional bonbon, a few leaves a day as a special treat; and some people use it flaked, instead of salt, or as a sprinkle on top of a salad. Check the nutrient content if you have issues with sodium, potassium, etc.

My sister gives me the *junk* from some packaged food service she gets. She's a very picky eater.
The last big fail was a packet of BBQ'd Kelp. I can't see anybody in their right minds trying to market the stuff as snack food, but they did.
Overly fishy, dry, with led to a horrible texture. Makes the dried kale she got look great by comparison.
