Seaweed grows in the ocean and absorbs minerals from seawater, but biologically it is algae rather than an animal.
1. Why this topic matters
In everyday language, some people group it with sea products. In vegetarian or allergy contexts, it is usually treated differently from animal seafood.

2. Practical benefits and usage
Seaweed is popular because it is rich in iodine, vitamins, minerals and antioxidants.

3. Important notes
People with seafood allergies or thyroid conditions should still read labels carefully and ask a professional when needed.
Conclusion
Used in the right way, seaweed can be a friendly, convenient and nutritious choice for everyday meals. The most important thing is to choose clean products and enjoy them in a moderate amount.
