T, congratulations on your NutriBullet and your new wellness journey.
Yes I think any seeds would be a great replacement for nuts. In many cases seeds may be more nutritious. You can also make milk like almond milk from seeds as well. Check out this recipe for sunflower milk!
Keep us informed of your progress and any tips you learn along the way please share them with us.
Healthy Wishes, Wally Bishop C.N.C.
