Explanation
The period between 700 and 1750 CE witnessed significant economic and cultural exchanges in the Indian subcontinent. A major aspect of this exchange was the introduction of new crops, fruits, and vegetables, primarily facilitated by the arrival of European traders (especially the Portuguese) and the movement of people across borders.

Key Takeaway:
The medieval period, particularly the 16th and 17th centuries, saw the Columbian Exchange bring New World crops like potatoes, maize, chillies, tomatoes, and tobacco to India, fundamentally altering the region's dietary habits.
