Can you show me a quality metric where American fruits or vegetables are consistently different compared to other countries? These are commodities, after all, so there is little differentiation. Is it visually, callorically, or nutritionally different somehow? I immediate went to visually, because one does notice this in the US compared to Latin America. Everyone is jumping on me about tomatoes, but Europe has the same bland greenhouse tomatoes in my experience.
