SUGAR
& HEALTH
Of-late,
sustained publicity campaign is being made by the producers of chemical
sweeteners against sugar consumption by attributing to it various health
problems. This has no scientific basis at all. Sugar is a perfectly healthy
product as would be evident from the following:
MYTHS
|
FACTS |
CAUSES
DENTAL CARIES: |
It
is an infectious disease caused by the interaction of bacteria
which reside in plague on the surface of the teeth with retained
food particles especially carbohydrates. Good oral hygiene
is essential which include reducing the frequency of intake
of carbohydrates and drinks as well as regular dental check-ups
and using fluoridated toothpaste when brushing teeth. |
|
SUGAR
CAUSE OBESITY: |
Scientific
studies show that people who are over weight often eat less
sugar than thin people and there is plenty of evidence to
show that carbohydrate rich diets can help suppress appetite |
|
EATING
SUGAR CAUSE DIABETES: |
Diabetes
is a disorder of the body's metabolism. Many scientific studies
show that the risk of diabetes is inversely related to carbohydrates
and sugar consumption. In other words, people who develop
diabetes have been found to eat less sugar than healthy people. |
|
SUGAR
CAUSE CORONOARY HEART DISEASE (CHD): |
The
researchers indicate that sugar is not a cause of coronary
heart disease. As there is no consistent and independent relationship
between intake of sucrose or other carbohydrates and incidence
of coronary heart disease. |
|
EMPTY
NUTRITION: |
Empty
calorie myth is really an empty complaint. Sugar is consumed
as an essential or enhancing ingredient in wide variety of
nutritious foods. Also, there is no reason for any concern
as sugar consumption does not contribute to any nutritious
deficiencies in population. |

WHAT IS SUGAR
Sugars
are a major form of carbohydrates and are found probably in all green
plants they occur in significant amounts in most fruits and vegetables
there are three main simple sugars sucrose, fructose, glucose, sucrose
is in fact a combination of fructose and glucose and the body quickly
breaks down into these separate substances
THE
NEED FOR ENERGY
All
energy stored in food is derived originally from the sun and it is made
by green plant life. The sun's energy acts upon the green chemical "chlorophyll"
in the leaves of plants to produce sugars and Starches from the carbon-dioxide
in the atmosphere and the water from the roots by a process known as Photosynthesis
.These carbohydrates (starches and sugar) acts as a plants food and energy
supply. .The Energy need of human body is largely dependent on the carbohydrates
that are derived from plants.
A
BALANCE DIET
A
balanced diet can (and should) come from a variety of different foods
,calculated to give the desired levels of carbohydrates ,proteins, fats,
vitamins, and minerals .Nutritional scientists advocate that carbohydrates
should provide at least 50% of over energy requirements .
SUGARS
ROLE
Starches
provide the large part of our carbohydrate needs .The sugar which nature
provides alongside the starches in our food supply have also a very special
role to play in human metabolism for primitive man the sweet taste probably
acted as a signal that the food was safe to eat .For modern man sugar
is used to improve the palatability of many foods and can thereby encourage
a more varied diet.
THE
USE OF SUGAR IN FOODS
Sucrose
is a natural and economical sweetener .It is the most versatile of all
the sweeteners , performing many useful functions in a range of foods
- As a sweetener. - Acting as a preservative. - Enhancing flavour in foods
. - Providing bulk and texture in ice cream, custard, baked goods and
confectionary . - Acting as a food for yeast in baking and brewing beer
and cider. - Contributing to crust colour , and flavour and delaying staleness
in cakes and biscuits.
SUGAR
HAS MEDICAL VALUE
Apart
from sugar being a cheapest instant source of energy ,It has several medical
& therapentical Values some of them are as elaborated below
1.SUGAR
FOR ORAL REHYDERATION
Sugar is extremely valuable in treatment of serve infantile diarrhea,
a serious problem that kills around 3.5 million children in a year in
underdeveloped countries .Oral re-hydration treatment (restoring of liquids
by mouth) is used for infants with diarrhea due to cholera or re-hydrating
viruses . It is simpler and easier to mix sugar with salt to treat de-hydration
children even in The most remote areas .Further studies prove that oral
sucrose was an effective as intravenous Treatment in retaining re-hydration
2.
SUGAR HEALS WOUNDS
Sugar has tremendous healing power .Sugar helps in wiping out infections
in all types of wounds And speed up the healing time as well .For sugar
fills up open wounds and it dissolves in tissue Where micro organism cannot
survive
3.
SUGAR IS BEST CARRIER OF VITAMINE A AND MINERALS
Vitamin A deficiency in South American population is being combated successfully
with the use of fortified sugar .Encouraged by the results ,fortification
of sugar with vitamin A is being attempted to combat vitamin A as well
as mineral (iron ) deficiencies a major area of concern In some of the
developing countries
MYTH
ON SUGAR CONSUMPTION
Food
caused health impairment scares are always and will always be a legitimate
matter of concern to consumers There is a difference between the food
scare which effects one in two consumers and another which effects one.
In a million. It is important to put information in proper perspective
to assess the risk and to report accordingly .It is equally important
that the information is based on scientific evidence .Keeping this in
view we are giving hereunder. The scientific findings on various concerns
expressed over sugar consumption.
1.
EMPTY NUTRITION MYTH
The
complaint about sugar is that it contributes only calories but no nutrients
to the diet . "Empty calorie" myth is really an empty complaint.
Sugar is never eaten alone It is almost always consumed as an essential
Or enhancing ingredient in a wide varieties of other nutritious foods
.Sugar is a 100% utilizable carbohydrate Another way to look at this issue
is to ask whether there is any reason for Concern that sugar actually
contributes to any nutrient deficiencies in population .The answer is
no , A recent study concluded .There is no evidence that continuing to
eat the present level of sugar will result in inadequate micro-nutrient
nutrition
2.
SUGAR AND DIABETES
Diabetes
"mellitus" is a disorder of the body's metabolism .The carbohydrates
which a normal person eats are converted into glucose which is absorbed
into the blood stream and is used by the body for energy .The diabetic
person cannot utilize carbohydrates efficiently .as a result blood has
higher than normal amount of glucose and it is often present in urine
Though all the causes of diabetes are not known ,genetic factors play
a major part in the development of this disease The question of whether
sugar consumption is related to diabetes has been exclusively examined
through epidemiologic surveys and experimental data The consensus of the
scientific community is that sugar consumption is not Related to onset
of diabetes . Many studies shows that the risk of diabetes is inversely
related to carbohydrates and sugar consumption .That is people who develop
diabetes have found to eat less sugar than healthy people .These people
found to eat more fat and consume more total calories than healthy people
increasing there likelihood of becoming obese and risk of developing diabetes
. Once a person develops diabetes the intake of sugar and other simple
carbohydrates is usually restricted .However there is little actual evidence
to support this practice research now indicates that not all starches
and sugars are alike in there effect on blood sugar .For example carrots
can produce a higher blood sugar then a candy bar and honey has a greater
effect than sucrose .Eating modest amounts of sucrose as a part of regular
meals does not leads to higher amount of blood sugar as has been commonly
supposed .The dietary recommendations of the American dietary association
(ADA) Are in most respect the same as non-diabetic person and are based
on sound principal of nutrition . Eating a modest amount of sugar is acceptable
says (ADA) council of nutrition as long as metabolic control is maintained
.
3.
SUGAR AND CORONARY HEART DISEASE (CHD)
The
researches say that sugar is not a cause of coronary heart disease .The
issue has been thoroughly studied in recent years because of one scientist's
widely publicized theory of the 1960 that heart disease is linked to excessive
sugar intake .The medical community has resoundingly rejected this theory
. The prevailing view point is reflected in one scientist's conclusion
after reviewing the literature that the evidence available does not support
the view that the sugar in the level present in diabetes afflicted persons
is a causative factor in the development of (CHD) The American society
of clinical nutrition in (1979) stated there is no consistent and independent
relationship between intake of sucrose or other carbohydrates and incidence
of prevalence of (CHD) In an attempt to pin down the various risk factors
involved in (CHD )many studies of the lifestyle and diets of different
population have been conducted .A recent review of three major studies
-the Framingham study the Honolulu heart study the Puertorico heart health
program found no association between sugar consumption and ( CHD) risk
the (UK) panel on diet and cardio-vascular disease could find no evidence
that sugar was specifically related to ( CHD )despite a barrage of prepublication
by food activists that sugar was a major contributory factor It is generally
agreed that the primary diet factors involved in ( CHD) are nature and
amount of fat in the diet .That is why dietary guidelines frequently called
for a decrease in intake to be accompanied by an increase in carbohydrates
consumption .Although these guidelines often recommended that the increased
carbohydrate intake should take the form of complex carbohydrates .It
can include sugar .
4.
SUGAR AND OBESITY
Eating
too much of anything makes you fat specially if calories are consumed
if more than calories used up. Scientific studies show that people who
are over weight often eat less sugar then thin people and there is now
plenty of evidence to show that carbohydrates rich diet can help suppress
appetite .One explanation for this is that lean people have more active
lifestyle which not only keep them trim but also allow them to eat more
of the foods they like and less of fats .Which contributes more than twice
as many calories as sugar ,and alcohol also almost twice as many .
5.
SUGAR AND HYPOGLYCEMIA
Medical
community believes that this is a rare condition that has been over diagnosed
in recent years .Misinformation and the natural desire to find a physical
cause for poorly defined symptoms such as fatigue irritability and nervousness
have led to the popularization of hypoglycemia as a diagnosis even though
similar symptoms may also arise due to stress in our lives . Understanding
hypoglycemia is complicated by the fact that there is no standard medical
definition as to where a normal blood sugar levels ends and low blood
sugar begins .In fact there is a vide range of blood sugar levels that
can be considered normal. Recent investigations into how the body responds
to various carbohydrates indicate no reason to suspect the sugar poses
a special metabolic problem .Sugar has been found to have only a moderate
effect on blood sugar levels .Various carbohydrates sources such as carrots
and potato has been found to effect the body blood sugar more markedly
than sucrose In a recent symposium sponsored by the national alliance
for research on schizophrenia and depression a national organization based
on (GREAT NECK) . N.Y a study on the relationship between sugar and stress
and the brain mechanism that control weight and appetite was presented
according to this a pathway called the hypothalamo-pituitary-adrenal axis
has been identified as the main regulator of the body stress response
.It was observed that intake of more sugar reduced the level of corticosteroid
responsible for stress by almost half.
6.
SUGAR AND HYPERACTIVITY IN CHILDREN
This
statement is not supported by any medical evidence according to the American
medical association hyperactivity is a complex behavioural syndrome the
American council on science and health have questioned whether or not
it can be related to diet at all .The 1989 (UK) committee on medical aspect
on food policy ("COMA") concluded that sugar has no significant
specific effect on behaviour or psychological functions Research shoes
that the perceived effect of sugar on children behaviour has more to do
with the influence of people around them then with any sugar containing
food they are eating .
7.
SUGAR AND DENTAL CARIES
Dental
caries is an infectious disease by the interaction of bacteria which reside
in plague on the surface of the teeth with retained food particles especially
carbohydrate. This acid produced erode tooth enamel leading to the formation
of cavities .For caries to develop three factors are required -a susceptible
tooth bacteria and a carbohydrate food stuff .A susceptible tooth surface
which is not already decayed but prone to develop caries .Secondly micro
organisms present in the mouth which used micro organism food to grow
on the tooth surface .The ability of these micro organism to grow depends
upon the frequency of food consumption and the length of time it remained
in the teeth .Many tooth which contain little or no sucrose (but contain
other fermentable carbohydrates )are capable of performing tooth decay
. A primary consideration in dietary control of dental caries must be
that of frequency and form of intake . Food which adhere to or between
tooth surface may be particularly harmful Use of fluoride in drinking
water is the most efficient way to reduce incidence of caries in America
.The reduction in the dental caries has been 50% to70% as a result of
water fluoridation .In Ireland apart from fluoridated water usage of fluoride
tooth paste resulted in dramatic fall in tooth decay .Good oral hygiene
is obviously essential . The etilogy of dental caries is multifactorial
with oral microbial flora host factors and dietary factors being the three
major factors involved in the development of the disease .
8.
CHEMICAL SWEETENERS
From
time to time a number of chemical sweeteners were produced and used by
the public. With passage of time and further research, some of these had
to be banned as being harmful to health. It took quite some time before
such conclusions could be reached. In the meanwhile, gullible public were
induced into consumption of such harmful chemical sweeteners. A few such
instances are as follows:
Likewise
some of the recently introduced chemical sweeteners may subsequently prove
to be a health hazard since scientific research is a continuous process.
Consumption of such products may thus be beset with unknown risk which
may become known later at a stage when damage may have been caused due
to their consumption over a period of time. On the other hand, sugar,
whether expressed in terms of sucrose or fructose is a natural product
and is a wonderful gift of nature to the mankind. It has many virtues
and cannot cause health hazard unless misused. Therefore, the risk evaluation
between sugar consumption and that of chemical sweeteners must take this
important factor into account.
9.
Cyclamate
Cyclamate,
a cyclohexylsuphamic acid (related in its chemical structure to saccharin),
30-40 times sweeter than sucrose, was discovered in 1944 and became popular
in the mid-sixties when it was used primarily in soft drinks along with
saccharin.
Cyclamate
was banned in 1970 in the UK and the USA following some adverse toxicity
results, which indicated that it is carcinogenic in animals and causes
testicular atrophy.
However,
despite its ban in the UK and USA, it is still permitted in some European
countries, Australia and New Zealand.
10.
Saccharin
Saccharin,
sodium salt of ortho-sulphobenzoic acid, 300 times sweeter than sucrose,
was the first artificial sweetener to be discovered in 1879. Consumption
rates increased significantly during the war time (both 1 and II) when
sugar was rationed. Use of saccharin continued to increase in the sixties
and seventies due to the rising popularity of low calorie food and drink
and its low cost. Unlike sugar, saccharin has a lingering bitter metallic
after taste.
There
were fears about its safety when studies suggested that saccharin caused
bladder cancer in laboratory rats. Its use was banned in Canada in 1977.
The US Food and Drug Administration (FDA) considered banning it in 1977
based on this animal research. However, Congress placed a moratorium on
the ban to allow for more research on saccharin's safety. This moratorium
has been extended seven times due to continued consumer demand. The FDA
withdrew the ban in 1991, but the moratorium is still in effect until
the year 2002. The use of saccharine is permitted in the USA but the products
have to contain warning statement, "Use of this product may be hazardous
to your health. This product contains saccharin which ahs been determined
to cause cancer in laboratory animals".
11.
Over-Consumption of sugars and fat balance:
Dietary
carbohydrates are either immediately oxidised to provide energy, stored
as glycogen (an energy reserve) or converted to fat in the liver by a
process known as do novo lipogenesis. This is an energetically expensive
so carbohydrates do not contribute significantly to the fat store. There
are some concerns that as the proportion of refined carbohydrates increases
in the diet, de novo lipogenesis may contribute more than once thought
to the body's fat stores. This was investigated in a group of lean and
obese people who were over fed sucrose and fructose. The study showed
that although de novo lipogenesis was increased (by 2-3 times), it did
not contribute significantly to the body's overall fat balance –
confirming our original hypothesis, that carbohydrates do not contribute
greatly to the body's fat stores.
12.
High carbohydrates intake associated with lower measures of body weight:
A
study of dietary intake in 3000 men and women with type 1 diabetes found
that those who had higher intakes of carbohydrates, including sugars and
starches, had lower body mass index and waist circumference (WC). Intake
or saturated fats, those found in meat and dairy products, was associated
with higher measures of body weight. These findings are constantly reproduced
in studies.
13.
Nutrition guidelines and education of the Public
The
abstract discusses the purpose of dietary guidelines and the factors that
influence their effectiveness. It considers that holistic approaches that
are targeted to reduction in risks of dietary deficiencies, food-borne
illnesses and multiple chronic degenerative diseases are probably the
most useful for the nutrition education of the public. Guidelines also
need to be updated periodically and communicated effectively.
14.
Is waist circumference (WC) a useful predictor of coronary heart disease
risk ?
Measuring
WC is a simple and useful tool with which to measure abdominal obesity.
As abdominal obesity is known to increase the risk of developing coronary
heart disease, WC is considered, along with other measures, to be a good
means of predicting risk of coronary heart disease. A study was carried
out to investigate this but found it only to be true in the case of younger
subjects. In older subjects, once body mass index was known, WC did not
add to the prediction of risk of heart disease.
