Timing matters in my case. I regularly incorporate almonds or walnuts, hazelnuts, pecans or macadamias and occasionally cashews, pistachios, brazils or peanuts into our meals, except my own breakfast when my insulin resistance is at its perishing worst.
I hardly ever snack between meals, but we all have to keep that inner fire stoked. If hungry, I would go for cheese and celery, rather than reach for the peanuts.
When on the hoof, salted peanuts may be all that's available in a pub, say, that doesn't do food. It's as well to test as others have suggested, so you're aware of the likely effects. In my case, woe would definitely betide!
