SUBWAY was established in 1965 in the United States by Fred DeLuca and Peter Buck. It has grown to more than 40,000 shops across 111 countries worldwide, making it the largest franchise in the world. While SUBWAY sandwiches can provide a quick, reasonably priced meal with variety, they also contain high amounts of fat, sugar, and sodium which poses some health issues. However, SUBWAY remains popular as an alternative to other fast food restaurants like McDonalds.
