Dental Decay
Most soft drinks contain high concentration of simple
carbohydrates - glucose, fructose, sucrose and other simple
sugars. Oral bacteria ferment carbohydrates and produce
acid, which dissolves tooth enamel during the dental decay
process; thus, sweetened drinks are likely to increase risk ofdental caries. The risk is greater if the frequency of
consumption is high.
A large number of soft drinks are acidic, and some may have
a pH of 3.0 or even lower. Drinking acidic drinks over a long
period of time and continuous sipping can therefore erode the
tooth enamel.

Obesity And Weight-Related Diseases
One study followed 548 schoolchildren over 19 months and
found that each soft drink that a child added to his or her daily
consumption was accompanied by an increase in BMI of
0.24 kg/m2
.
In this studies, the absolute number of soft drinks consumed per
day was also positively associated with weight gain. The
consumption of sugar-sweetened soft drinks is also associated
with many weight-related diseases, including diabetes,
metabolic syndrome and cardiovascular risk factors, and
elevated blood pressure.

Sugar Content
Until 1985, most of the calories in soft drinks came from sugar or corn syrup.
High-fructose corn syrup (HFCS) has been criticized as having a number of
detrimental effects on human health, such as diabetes, hyperactivity,
hypertension, and other problems.
Human body breaks sucrose down into glucose and fructose before it is
absorbed by the intestines. Simple sugars such as fructose are converted into the
same intermediates as in glucose metabolism. However, metabolism of fructose is
extremely rapid and is initiated by fructokinase. Fructokinase activity is not
regulated by metabolism or hormones and proceeds rapidly after intake of
fructose. While the intermediates of fructose metabolism are similar to those of
glucose, the rates of formation are excessive. This fact promotes fatty acid and
triglyceride synthesis in the liver, leading to accumulation o f fat throughout the
body and possibly non-alcoholic fatty liver disease. Increased blood lipid levels
also seem to follow fructose ingestion over time.

Stimulant soft drinks and violenceStimulant soft drinks usually consist of higher-than-usual levels of
caffeine.
In December 2000, the Irish government ordered "urgent research"
into the effects of or stimulant soft drinks after the death of an 18-
year-old boy who died while playing basketball. He had consumed
three cans of "Red Bull," a stimulant soft drink. The article noted there
have been reports of a rise in aggressive late-night violence
occurring when people switch to these drinks while drowsy from too
much alcohol. The resulting violence was so pervasive that someestablishments in Ireland have refused to sell stimulant drinks.

Bone Density
Research suggests a statistically significant inverse relationship
between consumption of carbonated beverages and bone mineral
density in young girls, which places them at increased risk of suffering
fractures in the future. One hypothesis to explain this relationship is
that the phosphoric acid contained in some soft drinks (colas)
displaces calcium from the bones, lowering bone density of the
skeleton and leading to weakened bones, or osteoporosis.
Dr. Robert Heaney said that carbonated soft drinks, which do not
contain the nutrients needed for bone health, may displace other
foods which do, and that caused people who drink a lot of soft drinksalso tend to have an overall diet that is low in calcium.

Nutritional valueUnless fortified, soft drinks also contain little
to no vitamins, minerals, fiber, protein, or
other essential nutrients. Soft drinks may alsodisplace other healthier choices in people's
diets, such as water, milk, fruit juice, and
vegetable juice

Sports drinks
There are three problems with using sport drinks as a rehydration
solution. First, most soft drinks are diuretics, meaning they squeeze
liquids out of the body, thus exacerbating dehydration instead of
correcting it. Second, most people actually lose few electrolytes during
exercise. After exercise the body is usually in an electrolyte load having
lost more fluids than electrolytes.If sweating has been profuse,electrolytes can be replaced by drinking a lacto-fermented beverage
or pure mineral water, which contains a proper ratio of minerals
(electrolytes), and by eating a healthy diet containing Celtic sea salt.
Third, when we give sugar-laden drinks to dehydrated kids, the highsugar content requires that blood be sent to the stomach to digest it. This
fluid shift can lower the blood volume in other parts of the body making
them more susceptible to cramps and heat-related illnesses.
