Junk Food - Is this Good?

I believe all of us ever tasted all sorts of food that normally known as junk food. Common known definition of junk food is something which is consumable but not necessary.

Little did we know that the fried 'keropok' that we used to buy is called 'junk food' for a reason. Why?

Basically, the word 'junk' means something useless, something bad and no benefits. Here's what junk means in dictionary.com:

Isn't this means that junk food is actually something which is not suppose to be consumed but instead discarded? But why is it that we likes this food so much?
　
What about definition of junk food? Wikipedia defines junk food as "Junk food is a common term used for any food item that is perceived to be unhealthy and has low or poor nutritional value". Not only that, junk food actually contains too much calories and fats which are useless and may cause health problem such as obesity.

Junk food is loveable in-spite of the name "junk" given to it. The sweetness or sourness of the taste makes human just gets attach to it. One of the factor that makes us link to junk food is the conveniency. We can find junk food at anywhere; the mall, small shops, five-foot stall and even our office/school canteen. As I'm creating a blog about health, so this time I'll stress on the effect causes by junk food.

There are two types of effect ; the short term & the long term:
Short term:
Reduce energy - as junk food contains little or no nutritional value, therefore, our body will weakens due to the lack of nutritions.
Reduce our concentration - without energy, there's no concentration as blood circulation decreases.

Long term:
Heart disease & high cholesterol- as junk food contains very high amount of fats and calories, over consuming it will cause heart disease and high cholesterol level.
Obesity - consuming junk food daily can lead to obesity

So, stop eating those unhealthy food and let's get on with healthy lifestyle!
