Junk food refers to food items that are high in calories but low in nutritional value.
These foods often contain high levels of sugar, salt, and unhealthy fats, and are usually processed or pre-packaged.
Common examples include chips, candy, soda, fast food, and baked goods like cookies and pastries.
While they might be tasty and convenient, they typically offer little in terms of vitamins, minerals, and other essential nutrients your body needs to function well.
