When you discover, most of those are vegetation which have a really skinny pores and skin, or that we eat with the pores and skin on. I’m extra involved about these meals than I’m about one thing like a banana or an avocado—due to the thick outer pores and skin, it’s unlikely they’d be as affected by pesticides.”
