Yes, There Is A Difference Between Sweet And Field Corn - Tasting Table
Briefly

Sweet corn is cultivated for human consumption, featuring higher sugar content and harvested early for juicy kernels, while field corn, intended for livestock, is starchier and serves diverse industrial purposes.
The difference between sweet corn and field corn lies in cultivation: sweet corn is tender, sugary and harvested quickly, while field corn is dried and hard, suitable for animal feed and food products.
Despite its less appealing taste for humans, field corn is vital for food products like corn meal, tortillas, and even bourbon production, showcasing its versatility.
U.S. farmers devote over 90 million acres to corn annually, with sweet corn being a small fraction, highlighting the predominance of field corn in agriculture and industry.
