Sunflower seeds are high in mold content and can set back your recovery from my experience.
We can brainstorm some other snacks you can have on the diet. I would explore celery sticks and almond butter or eating fruit as you transition from a high sugar diet to a low sugar diet.
Other examples include the breads, pumpkin pie muffin bread, etc. If you get a dehydrator you can make homemade crackers and eat it with guacamole.
