Friday marks National Fast Food Day, just days ahead of the Thanksgiving national holiday.
Last month the Centers for Disease Control and Prevention released a four-year study that revealed that 1 in 3 adults in the U.S. consume fast food on a given day. With men and the young eating more fast food than women and the elderly.
Flying in the face of conventional wisdom, people with higher incomes were more likely to consume fast food than those with lower incomes, according to the survey.
Americans spent more than $208 billion on fast food in 2017, compared to just $6 billion in 1970, and are expected to spend $225 billion annually by 2021, according to Holidays Calendar.
