Hi foodiesue, welcome to Social Slimmers
Best of luck on SW, there are lots of people here who also follow the plan, so there's usually always someone who knows the answer!
With regards to nuts, they are not a free food of any form.
You can have some nuts as your healthy extra B choice, or use them as part of your syns.
Almonds:
16 almonds can be used as your B choice.
25g almonds varies between 7 to 8 syns, depending on brands... Sainsburys Whole almonds are 7 syns per 25g, as are Tesco Whole Foods almonds, and Waitrose Love Life almonds
Hazelnuts:
23 hazelnuts can be used as your B choice.
25 g almonds are a minimum of 8 syns, with a couple of brands being 8.5 syns per 25g.
Personally, I use fruit as my snack food. Snacking on speed food is a great way to help boost your losses. But then again I don't like nuts so I'd never choose them
