Fast food consumption has been linked to negative health impacts according to the document. The CARDIA study found those who ate fast food 2 or more times per week had a higher risk of heart disease than those who ate it less than once a week. Additionally, frequent fast food consumption is associated with weight gain and increased risk of obesity over time. In contrast, a healthy diet with fruits, vegetables, whole grains, lean protein and healthy fats can lower risks of chronic diseases. The document emphasizes that regularly eating fast food should be avoided in favor of whole, nutrient-dense foods for good health.

INTRODUCTION

4. WHAT IS FAST FOOD?
 Fast food is the term given to food that can be
prepared and served very quickly
 It is a commercial term, limited to food sold in a
restaurant or store with frozen, preheated or
precooked ingredients and served in packaging
for take-out/take-away.
 The fastest form of "fast food" consists of pre-
cooked meals which reduce waiting periods to
mere seconds

5. HISTORY OF FAST FOODS
 The concept of ready-cooked food for sale is
closely connected with urban developments.
 Homes in emerging cities often lacked adequate
space or proper food preparation accoutrements.
 Additionally, procuring cooking fuel could cost as
much as purchased produce.

6. FAST FOOD STATISTICS
 Regular fast food consumption increases 2.2%
every year.
 Statistics from a survey conducted by the
National Center for Health Statistics from
Center for Disease Control shows that a little
over one-third of people in eat fast food every day.
 Lunchtime is the most popular time for fast-food
consumption, as 43.7% of consumers eat their
fast food at this time, while dinner is a very close
second at 42%.

FAST FOOD

8. 8
Eventhough all fast food does
not have negative impacts,
most of them are poor in
nutrition as these items are
generally high in sugar, salt,
saturated fats, and trans fats.

9. SHORT TERM IMPACTS
 Spike in blood sugar
 Blood pressure
 Increased inflammation
 Affects nutrient intake
 Binge eating

10. LONG TERM IMPACTS
 Digestive system
 Immunity and inflammation
 Memory and learning
 Allergies
 Heart disease
 Obesity

11. IMPACTS ON MENTAL HEALTH
 Eating lots of fast food could also impact an
individual’s mental health and make them more
prone to depression and anxiety.
 A 2021 study found that healthy food such as
leafy greens, nuts, and fish induced positive mood
in people, while the opposite was true of fast food.

12. CHILDREN'S AND
JUNK FOOD
12

13. HOW THEY AFFECT THEIR STUDIES
 Poor nutrition: Junk food is often high in calories and low
in essential nutrients like vitamins and minerals, which
can lead to poor nutrition and deficiencies that can affect a
child's cognitive development and ability to learn.
 Lack of energy: Consuming a diet high in junk food can
lead to feelings of fatigue, which can make it difficult for
children to stay focused and engaged in their studies.
 Behavioral issues: Eating a diet high in junk food can also
lead to behavioral problems like hyperactivity, which can
make it difficult for children to concentrate and complete
their work.
 Weight gain: Junk food is often high in calories and can
lead to weight gain, which can negatively impact a child's
self-esteem and ability to participate in physical activities.
 Poor sleep: Consuming a lot of junk food can lead to poor
sleep quality, which can affect a child's ability to learn and
retain information. 13

14. HOW THEY AFFECT THEIR SOCIAL
BEHAVIOR
 Poor self-esteem: Consuming a diet high in junk food can
lead to weight gain, which can negatively impact a child's
self-esteem and confidence. This can make it difficult for
them to interact with their peers, and can lead to feelings
of isolation and loneliness.
 Behavioral problems: Eating a diet high in junk food can
also lead to behavioral problems like hyperactivity, which
can make it difficult for children to control their impulses
and interact appropriately with others.
 Lack of energy: Consuming a diet high in junk food can
lead to feelings of fatigue, which can make it difficult for
children to participate in social activities and maintain
friendships.
 Poor mental health: Studies have shown that there is a
relationship between diet and mental health, and
consuming a lot of junk food can increase the risk of
depression and anxiety. 14

23. CASE STUDY
 One example of a case study that looked at the
impacts of fast food on health is the CARDIA
(Coronary Artery Risk Development in Young Adults)
study. The study followed more than 3,000 young
adults over a period of 20 years to examine the
relationship between fast food consumption and
cardiovascular health.
 The study found that participants who consumed
more fast food had a higher risk of developing heart
disease. Specifically, those who consumed fast food
two or more times per week had a higher risk of
developing heart disease compared to those who
consumed fast food less than once a week. The study
also found that the more fast food a person consumed,
the higher their risk of developing heart disease. 23

24. 24
 Another study, conducted by the Harvard T.H. Chan
School of Public Health, found that people who
frequently eat fast food are more likely to gain weight
and become obese over time than those who rarely or
never eat fast food.
 On the other hand, a healthy diet that is rich in
fruits, vegetables, whole grains, lean protein, and
healthy fats can help lower the risk of chronic
diseases such as heart disease, diabetes, and some
cancers. Eating a variety of nutrient-dense foods,
staying hydrated, getting enough physical activity,
and getting enough sleep are all key components of a
healthy lifestyle.
 Overall, it is clear that a diet high in fast food can
have negative impacts on health, and consuming fast
food regularly should be avoided or limited as much
as possible. Instead, consuming a diet rich in whole,
nutrient-dense foods is an important aspect of
maintaining good health and preventing chronic
diseases.

25. CONCLUSIONS
 Food is known to play an important role in both the
development and prevention of many diseases. The habit of
taking food also varies from society to society. Globalization
and urbanization have greatly affected ones eating habits
and forced many people to consume fancy and high calorie
fast foods, popularly known as 'Junk food'. Fast food is an
important item of the food as it is readymade in nature and
easy to eat. Food eaten outside the home is now becoming a
significant and regular component of life. These rapid
changes in the levels and composition of dietary and
activity/inactivity patterns in transitional societies are
related to a number of socioeconomic and demographic
changes. Numerous studies have concluded that the poor
nutritional value, the excessive salt content and the degree
of saturated fats and trans fatty acid associated with fast
food products likely perpetuate the prevalence of
hypercholesterolemia, hypertension, type II diabetes
mellitus, obesity and cardiovascular disease in Westernized
societies. The present review describes the association
between the consumption of such foods and health
outcomes.
