I LOVE shellfish and eat shrimp at least a couple times a week as well as crab and a mix of other things. I wish I could throw lobster in a at least one a week. lol
Pumpkin seeds? I didn't think of that. I have a couple pounds drying at home right now I just took out of our pumpkins due to Halloween. I mostly planned on saving some for re planting and drying some to eat but didnt think about the zinc.
