Junk food is defined as “any food, which is low in essential nutrients and high in everything else – calories and sodium”. Junk foods contain little or no proteins, vitamins or minerals but are rich in salt, sugar, fats and are high in energy (calories). Junk food is popular because it is tasty; but it is unhealthy. It is low in fiber, high in fat, and sugar in liquid form. Studies have shown that despite being unhealthy, junk food induces gorging that leads to obesity.
