Yes, nuts are high in carbs. They are also very good for you. The best way to go, provided you are in Ongoing Weight Loss and have reached the nuts/seeds rung, is to weigh them before nibbling. I eat nuts most days.
I found that too many - and not as many as I would have liked - slowed and even stalled my weight loss. I have to be strict about the quantity I eat. Not everyone has this problem but it is wise to take care, just in case.
