Junk food refers to food items that are typically high in calories, sugar, salt, and unhealthy fats, but low in nutritional value. These foods are often highly processed and include items such as candy, chips, soda, fast food, and certain baked goods like cookies and doughnuts. Junk food is popular for its convenience, taste, and affordability, but regular consumption can lead to health issues such as obesity, heart disease, diabetes, and other chronic conditions.
