/ˈdʒʌŋk fuːd//ˌdʒʌŋk ˈfuːd/
The term "junk food" originated in the 1950s, likely coined by nutritionists or food writers. It emerged as a way to describe food items high in calories, sugar, fat, and salt, but low in nutritional value. These foods were often perceived as "empty calories" providing little to no health benefits. The term's popularity increased in the 1970s, alongside the rise of processed food and fast-food chains. It became a widely recognized label for commercially produced, often unhealthy, food options.
