Junk food is a term used generally to mean any food that has no or very little nutritional content. These foods are commonly considered unhealthy most nutritionists. Pizza, burgers, sodas, etc. are typical examples of junk foods (Bhatti, at al, 2015). These foods among other junk foods are considered to have much sugar, salt, and fats are known for instant kicking of energy in teenagers. However, research points out junk foods to be addictive and highly challenging to overcome. The paper covers the causes and effects of eating junk foods.

Causes of junk foods

Junk foods are caused fundamentally by their ingredients which are contained in them. Some of the critical objectives of junk food include:

Excess Sugars, most of the junk foods that are highly preferred by teenagers, have their most prominent content of ingredients as excess sugars. These sugars have various hazards to the human body. Among them include brain inflammation and fatigue.


Excess calories, junk foods are also caused the excess calories with less or no dietary fibers, proteins vitamins or even minerals. Fast foods mostly sold in restaurants are often junk foods loaded with high contents of rats and sugar.

Excess fats, junk foods are also caused by much fat in the foods we eat. Such foods may be fried meat, pizza, snatches, etc.

Effects of Junk Food

Memory Defects, Consumption of junk foods causes memory and learning problems. Research, as published in the American Journal of clinical nutrition 2011, proves that consumption of junk foods would lead to reduced cognitive tests, lack of moods and deteriorated memories. The high sugars and fats ion junk foods lower brain appetite which leads to unhealthy memory formation.


Loss of Appetite, Too much consumption fats in fried and processed foods produce varied signals to the brain that makes it hard to handle and realize when starving and need to eat. Consequently, one may end up overeating (Neupane, at al, 2017). Moreover, junk foods consumption may cause inflammation in the hypothalamus part of the brain that controls body weight.

Uncontrolled Cravings and Depression, Excess sugar and fats in junk foods, adversely affect the chemical activity of the brain where it tends to depend much on such diets. Also, the consumption of too many fast foods leads to a lack of amino acids tryptophan which may increase the feeling of depression.




In summary, junk foods contain the excess of sugar and fats which are profoundly harmful to our body. Some of the hazards of these foods are weak growth and development, dental problems, obesity, high blood pleasure, depression, etc. Foods with excess sugars and fats should, therefore, be avoided to prevaricate the dangers associated with them all.
