WHAT IS JUNK FOOD 

"Junk food" refers to food that is rich in calories from macronutrients like sugar and fat, and is often high in sodium, which makes it very appealing, while being low in dietary fiber, protein, or essential micronutrients such as vitamins and minerals.

It is also referred to as "high in fat, salt and sugar food" . The term junk food has a negative connotation that dates back to the 1950s.

Definitions can vary based on context and over time. Some foods that are high in protein, such as meat cooked with saturated fat, might be classified as junk food. Fast food and fast-food establishments are frequently associated with junk food, although not all fast foods can be strictly labeled as junk food. Items like candy, soft drinks, and heavily processed foods, including certain breakfast cereals, are typically categorized as junk food; much of this falls under the ultra-processed food category.

Worries about the adverse health impacts of a diet rich in junk food, particularly obesity, have led to public health initiatives and limitations on advertising and sales in various countries. Recent research suggests that a diet high in junk food can elevate the risk of depression, digestive problems, heart disease and stroke, type 2 diabetes, cancer, and premature death.

In straightforward terms, junk food signifies food that is rich in calories (from sugar, fat, and salt) but deficient in essential nutrients like fiber, protein, vitamins, and minerals.

They are commonly known as HFSS foods – High in Fat, Salt, and Sugar – or ultra-processed foods due to their frequent composition of refined ingredients, artificial colors, preservatives, and flavor enhancers.

To summarize, junk food delivers a rapid influx of taste and energy — but provides little nutritional benefit in return.
