2. TERM
Junk food is an informal term applied to some
foods which are perceived to have little or no
nutritional value, or to products with nutritional
value but which also have ingredients
considered unhealthy when regularly eaten, or
to those considered unhealthy to consume at all.

3. The term ‘JUNK FOOD’ was aptly coined by Michael
Jacobson, director of the Centre for Science in the
Public Interest, in 1972 as slang for foods of useless
or no nutritional value. There are rich in sodium
salts or sugar and fats which provide high calories
yet useless in value. A quick look at food facts tells
us junk food and diet does not go hand in hand.
Perhaps this is the reason why junk foods are also
called as empty calorie foods. Junk food producers
claim to have made improvements to nutrition junk
food can provide.

4. NUTRITIONAL VALUE
Junk food refers to fast foods which are easy to
make and easy to consume. They are zero in
nutritional value. They have only fats lying in it
causing ill effects on the health of the consumer.
The taste is the most attractive feature in junk
foods.

5. TYPES
Junk food are typically ready to eat convenience
foods containing high levels of saturated fats,
salts, or sugar; and little or no fruit, vegetables,
or dietary fibre.
Junk food includes foods such as soft drinks,
hamburgers, hot dogs, ice cream, cake, French
fries, chocolate and other confectionary, pizza,
cookies, fried chicken and donuts.

6. HARMFUL EFFECTS OF JUNK FOOD
Lack of Energy
Junk foods do not contain any nutrients that are
beneficial to the human body. In most cases,
these foods are filled with harmful
carbohydrates, facts and cholesterol that do not
provide any useful energy. As a result, somebody
consuming junk food has reduced level of
essential nutrients thereby causing weakness in
the body.

7. HARMFUL EFFECTS
Poor Concentration
One disadvantage of consuming junk food is that it
contains high amount of oil and fat. As a result,
human body find this food difficult to digest and
needs to spend high amount of blood and
enzymes.

8. HARMFUL EFFECTS
Heart Diseases
Junk foods have been identified as a major cause
of heart diseases including myocardial infraction,
cardiac arrest atherosclerosis. This is due to the
fact that junk food contains excessive amount of
low-density lipoproteins and cholesterol that get
deposited on the inner linings of blood vessels.
This results in formation of plaques and the
heart is required to put an extra effort for
pumping blood through arteries.

9. HARMFUL EFFECTS
Liver Failure
Even liver gets damaged due to presence of
ingredients such as fat, cholesterol and salt
inside the junk food.
Diabetes
Junk foods also cause damage to the pancreas
resulting in insulin-dependant diabetes mellitus
(IDDM).

10. ADVERSE EFFECTS OF JUNK FOOD
If ingredients make junk food appealing, it is the
same reason that makes them health hazardous
too. The fat contents, barring a few
manufacturers, have high cholesterol levels.
Secondly, the sugar and sodium salts have their
effects on health. High calorie content with sugar
can lead to obesity. Cholesterol and salt are
known to setoff blood pressure, stroke and heart
diseases in a chain. Excessive salts can affect
functioning of kidneys too.

11. CONCLUSION
Nevertheless, junk foods are popular because of
their simplicity to manufacture, consume and of
course, their taste. People have their own
notions about a certain food being listed as junk.
However, chocolates, burgers, pizzas, potato
wafers and fries will surely find their ways into
everyone’s list.
