All fast foods are not junk foods. Junk foods are classified as hamburgers, pizzas, french fries & tacos. Whereas fast foods can be high or low in nutritional value. For example – Salads are considered to be high in nutritional value. Junk Food does not provide any nutrients that are required by the body for a healthy lifestyle. Processed foods are mostly junk food, as they have high sugar content present in them.

The UK Advertising Standards Authority uses nutrient profile to classify it as a junk food. Foods are scored from A to C, depending upon their nutritious value. The difference between A & C defines whether it is a junk food or not.

The junk food label is described as nutritionally meaningless: food is food, and if there is zero nutritional value, then it isn’t a food. Co-editor Vincent Marks explains, ‘To label a food as ‘junk’ is just another way of saying, ‘I disapprove of it.’ There are bad diets – that is, bad mixtures and quantities of food – but there are no ‘bad foods’ except those that have become bad through contamination or deterioration.

Why Are Junk Food Bad for You?

According to Dr. Sharma, the red flags that you should look out for and avoid bringing home include trans-fats, refined grains, salt and high fructose corn syrup. Avoid foods that say corn sweetener, corn syrup, corn syrup solids, partially hydrogenated, fractionated, or hydrogenated on their label. So next time you want to know if what’s on your plate is junk or not, ask yourself these 3 crucial questions:

  1. How many calories am I consuming in this one serving?
  2. What are the nutrients that I should be taking with every meal that will fulfill my nutrition requirements?
  3. How fresh are the food items that I am intaking in my meal?

Calories from Snack Foods

Popular snack foods are usually commercially prepared and packaged, like chips, cheese puffs, candy bars, snack cakes, and cookies. Snack foods have a high amount of unwanted calories that one must avoid or atleast keep in check. Between the years 1977 and 1996 snack food contributed a 3o% increase in the total calorie intake in children aged 2 to 5.

Why Junk Food Is so Popular?

Junk food is very popular because it is cheaper, convenient, taste good, takes less time to prepare & is served quickly. Now a days you can find numerous restaurants serving burgers, pizzas, french fries, ice-creams, waffles, cakes etc. They have become very popular now a days. Every other person is seen consuming this food. Junk food is made from cheaper quality ingredients like high fat meat, refined grains, sugar & trans-fat. They have high amount of salt, oil, calories present in them.

Is Fast Food Bad?

An individual cannot say food is good or bad. But there are some foods that you should consume on daily basis. Fast foods are one of them, which should not be consumed on a daily basis. Fast foods contain high amount of salt, sugar, trans-fat, cholesterol etc. which is not healthy for a human body. You can consume fast food, but once in a week or month depending upon an individual. Consuming excessive amount of fast food over a longer period of time can lead to health-related problems which are not good for your body. Eating these foods affects your body a lot & can lead to high blood pressure, heart diseases, kidney failure, obesity etc.

  4. Junk food is high in sugar. Due to consuming such a large amount of sugar in a meal your metabolism comes under stress. These foods lack in proper nutrients, which are required by the body.
  5. Recent researched has shown that consuming bad fats present in junk foods replaces the healthy fats present in the body which results in improper brain signaling mechanism.

Advantage of Junk Food

  • Junk food is cheaper than healthy foods & is easily available in the market.
  • They are made quickly & saves preparation time.
  • These are easy to carry & can be eaten anywhere & anytime.
  • These satisfy your cravings.
  • When an individual’s cravings are fulfilled he or she likes that food a lot.

Disadvantage of Junk Food

  • Junk food increases your weight rapidly.
  • Increase in weight lead to obesity.
  • High presence of fats results in health-related problems.
  • High amount of sugar junk food (ice-creams, chocolates etc.) lead to diabetes.
  • High amount of salt in fries lead to kidney problems.
  • Junk foods have additives, preservatives & trans-fat in them which are very harmful for a human body.

Fast Food and Overeating

of course, junk food is also readily available at restaurant chains across the country in the form of French fries, chicken nuggets, shakes, soda, etc. Not only are most fast foods not terribly healthy, one study indicates that there may be something about fast food that actually encourages gorging.

In the study, from the Children’s Hospital in Boston, teens Age 17 were given three types of fast food meals (all including chicken nuggets, French fries, and cola). In one meal, the teens were served a lot of food at once. In another, a lot fast food was served at the same time, but in smaller portions. And in the third test meal, a lot of food was served, but in smaller portions over 15-minute intervals.

Health Effect

When junk food is consumed very often, the excess fat, simple carbohydrates, and processed sugar found in junk food contributes to an increased risk of obesity, cardiovascular disease, and many other chronic health conditions. A case study on consumption of fast foods in Ghana suggested a direct correlation between consumption of junk food and obesity rates. The report asserts that obesity resulted in related complex health concerns such upsurge of heart attack rates. Studies reveal that as early as the age of 3o, arteries could begin clogging and lay the groundwork for future heart attacks. Consumers also tend to eat too much in one sitting, and those who have satisfied their appetite with junk food are less likely to eat healthy foods like fruit or vegetables.

Testing on rats has indicated negative effects of junk food that may manifest likewise in people. A Scripps Research Institute study in 2oo8 suggested that junk food consumption alters brain activity in a manner similar to addictive drugs like cocaine and heroin.

Eating junk food multiple number of times creates pleasure centers in rat’s brains which makes them desensitised to the enjoyment associated with junk food, which makes them want more food to satisfy the craving. When the junk food is replaced in the rat’s diet with nutritious food, the rat’s chose to starve themselves rather than taking in any food.

Anti-Junk Food

Since junk food consumption is a major concern globally, most governments encourage a healthy lifestyle and are adopting various forms of legislative actions, some minor and some major to make sure its citizens are healthier. A 2o14 UN report by Anand Grover, talked about various effects of unhealthy eating. It called on governments to take strict action in order to develop nutritional habits. It called for rigorous advertising of nutrition and the ill effects of junk food.


So, I would like to conclude that fast food or junk food is mouth-watering & cravings for them doesn’t stop for an individual. Consuming junk food once in a week or month is fine but consuming regularly is very harmful for your body as it brings you a lot of health problems. The amount of sugar, salt, trans-fat, cholesterol present in the food are not fir for the body & body can’t handle that much pressure.

Don’t eat fast food, but if you want to eat make them at your home. Making them at home is more better than eating from outside.
