Junk food is a term applied to some foods which are perceived to have little or no nutritional value, or to products considered unhealthy to consume at all. They are typically ready-to-eat convenience foods containing high levels of saturated fats, salt/ sugar and little or no fruit, vegetables or dietary fibre.
Junk Foods thus have little or no health benefits. Nevertheless, the Junk Foods are popular because of their simplicity to manufacture, consume and of course their taste. People prefer to eat them while watching TV and also save themselves a lot of hassles and time.
