Hapi Hot Wasabi Peas, 9.9-Ounce Tins (Pack of 4)

Are these vegetarian? I know some brands include powdered shrimp as an ingrediant.

Gluten free?

Are there any brand of Wasabi peas that are just crunchy and not so hard that they break your teeth?

Why does it say may have an adverse effect in activity and attention in children?!
