Potatoes improved the European diet nutritionally.

Step-by-step explanation:

Potatoes didn´t exist outside of South America before 1500. During the Columbian exchange traders brought maize, potatoes, and tomatoes to Europe, all of which became fundamental crops by the 18th century in that region.

Potatoes and maize provided caloric and nutritional improvements in Europe´s diet and generated a more diverse and rich food production.
