Junk food

 Junk food is unhealthy food that has a lot of fat, salt and sugar in it.

Many people are overweight and don’t understand why. The role of fast food in putting on weight is very important.

Food has a lot of additives if it is not home-cooked. Foods like pastas, pizzas, burgers look nice and taste nice because of:

 artificial colours,

 flavourings 

 preservatives

Fast food is highly unhealthy and can never give the nutrients and vitamins of a healthy home-cooked meal. Fast food is inexpensive because it is usually made with cheaper ingredients such as

 high-fat meat, 

 refined grains,

 and added sugar and fats,

 instead of nutrients.
