Soft drinks, known for their effervescence due to carbonation, pose various health risks including obesity, kidney failure, and tooth decay, arising from their harmful components such as high sugar content, artificial sweeteners, and acids. Consumption of these beverages is linked to serious health issues like heartburn, emotional disorders, and increased rates of certain cancers. The document outlines the negative impacts of ingredients like caffeine and preservatives, emphasizing the absence of nutritional benefits in soft drinks.

WHAT ARE SOFT DRINKS ? ? ? ? ? ? ?
Soft drink is also known as club soda, soda
water, sparkling water, carbonated water &
fizzy water.
It is water into which carbon di oxide gas
under pressure has been dissolve, a process
that cause the water to become effervescent.
and the process is called carbonation.
Soft drinks have become so much a part of
modern living, especially in major cities
around the world.
It particularly appeals to the younger
generation who drinks soft drinks in place
of water

HEART BURN & CELL DAMAGE:
 Carbon dioxide can change the pH
of water. According to the following
reaction:
 CO2 + H2O --> H2CO3
 Carbonated drinks are made by
injecting carbon dioxide into the
water under pressure. The more
carbon dioxide injected, the lower
the pH, the more acidic it gets, the
more fizzy it is.
 Too much carbon dioxide kills
healthy cells. Dead cells cause an
acidic environment.
 Soft drink consumption is a
strong predictor of
Heartburn/Acidity.

7. 7
EFFECT OF CAFFEINE
 Caffeine is an addictive drug that enhances the flavor of soft
drinks.
 It artificially stimulates the nervous system and increases the
heart rate.
 Excessive caffeine consumption is linked to cancers of the
bladder and stomach and raised blood pressure.
 It may even contribute to birth defects in babies.
 Excessive urination and other health problems.

CAFFEINE OVERDOSE:

OBESITY: Drinking a single 330 ml can a
day of sugary drinks translates to
more than 453.592 gm of weight
gain every month.
The relationship between soft
drink consumption and body
weight is so strong that is each
additional can of soft drink
consumed, the risk of obesity
increases 1.6 times.
Sugar-sweetened beverages are
linked to more than 180,000
obesity related deaths a year.

ASPARTAME
• C 14 H 18 N 2 O 5
SACCHARIN
• C7H5NO3S

11. 11
ASPARTAME
 A white, crystalline, odorless, slight
ly water soluble non-carbohydrate
powder, C 14 H 18 N 2 O 5,synthesized
from amino acids, that is 150-200
times as sweet as sugar.
 It does enhance the taste of the
drink but it also cause numerous
adverse side-effects. Common
complaints include migraine,
memory loss, emotional disorders,
blurred vision, ringing in the ears
and shortness of breath.

SACCHARIN (C7H5NO3S)
 Saccharin is an artificial sweetener
with effectively no food energy
which is approximately 300 times
as sweet as sucrose or table sugar.
 It has been proven to cause
bladder cancer.

PRSERVATIVES
SODIUM BENZOATE
 It is present in most soft
drinks.
 This chemical is known to
cause asthma, rashes and
hyperactivity.
SULPHUR DIOXIDE
 It is also used in some soft drinks to
preserve the color of say, carbonated
lemon juice from turning brown.
 This chemical is used for industrial
bleaching.
 It is so toxic that repeated exposures
to it can cause fainting spells, skin
eruptions, swelling, tightening of the
chest, shock, coma and even death.

TOOTH DECAY: The acidity can dissolve the mineral content of
the enamel, making the teeth weaker, more
sensitive, and more susceptible to decay.
Soda's acidity makes it even worse for teeth
than the solid sugar found in candy.
Dental experts continue to urge that people
drink less soda pop, especially between meals,
to prevent tooth decay and dental erosion.

Impaired Digestive System
 The digestive system, that starts
from the mouth and ends up at the
anus only the stomach can resist an
acidic environment up to pH 2.0.
 But before the acidity of soft drink
reaches the stomach it passes
through all the other organs
involved in the digestive system
thus causing an abnormal acidic
environment.
 The phosphoric acid present in soft
drink competes with the
hydrochloric acid of the stomach
and affects its functions. When the
stomach becomes ineffective, food
remains undigested causing
indigestion, gastric issues or
bloating (swelling of stomach).

Dehydration
 Both caffeine and sugar cause
dehydration.
 Caffeine is a diuretic and causes
an increase in urine volume
 High concentration of sugar is
drawing off water because your
kidneys try to expel the excess
sugar out of the blood.
 When you drink a caffeinated
soft drink to quench your thirst,
you will actually become
thirstier

18. 18
KIDNEY FAILURE:
Drinking large amounts of soft
drinks containing phosphoric acid
may be especially harmful.
Having poor kidney function can
lead to unusually high levels of
phosphorous in your blood that
lower calcium levels, increasing
your risk of bone disease and
brittle bones.
That cola beverages can increase
the risk of kidney problems, more
so than non-cola sodas.
Large quantities of cola result in
enhanced kidney stone formation
