When we think of sugar, the first thing that comes
to our mind is cane sugar. This by far the most common sugar found in the
world. The sugar is made from sugarcane plant.
Sugar is the common name for sweet, short-chain,
soluble carbohydrates, many of which are used in food. They are
carbohydrates, composed of carbon, hydrogen, and oxygen.
Carbohydrates consist of simple sugars, starches
and fiber. Simple sugars are called monosaccharides. They are glucose (also
known as dextrose), fructose and galactose. The most common type of sugar that
we use in our food is called sucrose and is derived from plants. Although many
plants have sugar in their tissues, only sugarcane and sugar beet contains
sugar in sufficient concentration for efficient extraction.
Carbohydrates are the main source of energy for our body. During the process of digestion our body converts carbohydrates into glucose (we call this blood sugar). Cells utilize the glucose from the blood for body’s energy needs. When our system breaks down simple sugars quickly, our body responds with the release of insulin which enables the absorption of glucose. Over time the pancreas which produces insulin (a hormone) wears out and becomes incapable of producing insulin. This leads to diabetes, heart disease and obesity.
Sugar has been linked to obesity, and suspected of,
being a cause of digestive problems, diabetes, cardiovascular disease,
dementia, macular degeneration, and tooth decay. Excess sugar can also depress
immunity.
Various studies were conducted but only with varying results. The lack of control population not consuming sugar is the main reason for this.
People who cannot take sugar will resort to some
artificial sweeteners such as aspartame, saccharine, sucralose, neotame and
acesulfame potassium.
Sucrose
Sucrose is commonly known as table sugar or just
sugar. It is obtained from cane or beet. Sugar is present in
all fruits, vegetables and tubers in the plant kingdom. This is the result of photosynthesis,
the process by which plants transform the sugar energy into food.. When we consume sucrose it is converted into glucose and fructose
and then taken up by their specific transport mechanisms. Sugar made from
cane and beet look the same and it will be difficult to tell the difference.
When one molecule of glucose is bonded with a fructose molecule you get a sucrose molecule.
Refined sugar is more harmful than naturally occurring sugar. Sugar gives texture and color to baked goods. It is necessary in fermentation by yeast. It acts as a preservative in jams and chutneys.
Consuming lot of sugar can lead to pancreatic cancer and damage the liver. It will also lead to obesity. Sucrose has a simple molecular structure and is digested and released into the blood stream faster than it can be burned. If sucrose is allowed to remain on the teeth, it will allow bacteria to grow which in turn will produce acid which will erode the enamel of the teeth.
Fructose
Fructose is found in fruits and honey.
Commercial fructose is extracted mainly from corn. Every cell in the body can use glucose but fructose is digested only in the
liver. When the liver cannot cope with the amount of fructose it will convert
the sugar into fat and pass it in the blood stream as triglycerides.
High fructose diet can cause build-up of fat cells around
the liver, heart and digestive organs. This may happen in a short time span of
10 days.
If you’re energy depleted (i.e. an elite athlete),
fructose can be converted to glycogen (liver starch) as a storehouse for ready
energy, which can then be fished out of your liver if your body needs glucose
in the future (for more exercise or if you’re starving). But most of us aren't energy depleted, so exercise can be an antidote to
excess fructose consumption.
Fructose gets turned into liver fat, leading to
insulin resistance, obesity, high blood pressure, elevated triglycerides and
high LDL. Fructose causes depletion of vitamins and minerals. It may contribute
to cardiovascular disease, liver disease, cancer, arthritis, blood tryglicerides and cholesteroland even gout.
Excessive consumption of fructose can lead to
Bloating, gas, stomach pain, heartburn and nausea often occur as a result of
indigestion. Dr. Mercola suggests that that pancreatic tumour cells use
fructose, specifically, to divide and proliferate, thus speeding up the growth
and spread of the cancer.
Actor Ashton Kutche who was to play the character
of Steve Jobs in the upcoming film “Jobs,” was admitted to the hospital,
because of his all-fruit diet, 2 days before starting shooting of the movie.
Jobs had adopted an all-fruit diet in his younger
days. The brand 'Apple' he created was due to this obsession. Pancreatic cancer
killed Steve Jobs on October 5, 2011, at the age of 56. Dr. Mercola muses that
even though Jobs consumed a fruitarian diet years before he contracted his
pancreatic cancer, there could be some relationship.
Galactose
Galactose is a monosaccharide. When combined with
glucose it results in the disaccharide lactose. Lactose is naturally found in
milk and other dairy products. In the human body, glucose is changed into
galactose to enable the mammary glands to secrete lactose. However, most
lactose in breast milk is synthesized from galactose taken up from the blood.
Glucose is the primary source of metabolic energy
for humans because it is more stable than galactose. Many species (including
humans) have the ability to convert galactose to glucose.
Galactose is found in dairy products, sugar beets,
other gums and mucilages. It is also synthesized by the body.
Glucose
Glucose is the primary source of metabolic energy
for humans bacteria and many other organisms.. It is found in honey, fruits and
vegetables. Glucose is found in the blood. When a person has diabetes we say
that blood glucose level is high.
Body converts excess glucose into glycogen and
stores it in the liver and inside muscle tissue around the body for future
usage.
Lactose
Lactose is found in milk, made from glucose and
galactose.
Some people are intolerant to lactose. Lactase, in
enzyme produce by the small intestines, is required to digest lactose.
When one molecule of glucose is bonded with a
molecule of galactose you get lactose, which is commonly found in milk.
Maltose
Maltose or malt sugar is found in germinating barley, other cereals and molasses. Maltose is also created during beer brewing process. Our body also makes maltose from the starchy foods like potato and bread. It is made up of two joined glucose molecules.

When the food passes into the small intestine's
duodenum from the stomach, the small intestine releases maltase that can digest
maltose. Once maltase breaks down maltose into two units of glucose, glucose is
free to be absorbed by the gut.
High maltose corn syrup is a food additive, sweetener
and preservative. It is made from corn-based sugar. It is believed that it is
better than high fructose corn syrup.
