Sugar is the generalised name for sweet,
short-chain, soluble carbohydrates, many of which are used in food. They
are of various kinds and from different sources, mainly plants, but
especially extracted in sufficient concentrations from sugarcane and
sugar beet.
Simple sugars are called monosaccharides
and include glucose (also known as dextrose), fructose and galactose.
The table or granulated sugar most customarily used as food is sucrose, a
disaccharide which, in the body, hydrolyses into fructose and glucose.
In recent times, the awareness of the
relationship between sugar and chronic diseases is ever-growing and
cannot be over-emphasised. According to a study published in 2013,
nearly one in five U.S. deaths is now associated with obesity. Obesity
is, indeed, a marker for chronic and potentially deadly disease, but the
underlying problem that links obesity to so many other serious health
issues — including heart disease, arthritis, cancer, infertility and
diabetes — is metabolic dysfunction.
Now, mounting evidence clearly shows that
added sugars, and processed fructose in particular, is a primary driver
of metabolic dysfunction.

One of the primary sources of calories
for many of us is sugar — specifically high fructose corn syrup in soda,
fruit juice and processed foods. Because of advances in food processing
technology in the 1970s, fructose derived from corn has become very
cheap and is widely used in the majority of processed foods for
increased sales.
The body metabolises fructose much
differently from glucose — which is the energy that most body cells and,
indeed, all living cells utilise. Only about 20 per cent of glucose in
the body is metabolised by the liver, as most cells in the body utilise
it for energy. On the contrary, the entire burden of metabolising
fructose falls on the liver, where excess fructose is quickly converted
into fat — very low density lipoproteins and triglycerides, which
explains the weight gain and abdominal obesity experienced by so many.
Refined fructose is actually broken down
very much like alcohol, damaging the liver and causing mitochondrial and
metabolic dysfunction in the same way as ethanol and other toxins. It
also causes more severe metabolic dysfunction because it’s more readily
metabolised into fat than any other sugar.
The fact that refined fructose is far
more harmful to the health than other sugars was recently highlighted in
a meta-review published in the Mayo Clinic Proceedings, the premier high quality peer-reviewed clinical journals in general and internal medicine.
According to modern Mayr medicine, many
of the harmful bacteria in the intestinal tract such as Candida and
other fungi multiply rapidly when sugar is present in the tract, since
they are able to digest sugar.
A study published in the Journal of the American Medical Association concluded
that there’s “a significant relationship between added sugar
consumption and increased risk for cardiovascular disease mortality.”
The 15-year-long study, which included
data for 31,000 Americans, found that those who consumed 25 per cent or
more of their daily calories as sugar were more than twice as likely to
die from heart disease as those who got less than 10 per cent of their
calories from sugar.
On the whole, the odds of dying from
heart disease rose in proportion with the percentage of added sugar in
the diet, regardless of age, sex, physical activity level, and body mass
index.
Fructose is the primary cause of
non-alcoholic fatty liver and elevates uric acid, which raises blood
pressure, stresses the kidneys, and leads to the chronic, low-level
inflammation that is at the core of most chronic diseases such as
arthritis, and leading to heart attack and stroke. Metabolically
speaking, fructose is alcohol “without the buzz.” Elevated uric acid
levels have been implicated by many studies in diseases such as
arthritis, hypertension, heart disease, obesity, stroke, kidney disease
and preeclampsia in pregnancy — where uric acid’s ability to promote
inflammation, oxidative stress and endothelial dysfunction has a
debilitating impact on placental development and function and maternal
vascular health.
Fructose tricks the body into gaining
weight by giving false signals to our metabolism — it turns off the
body’s appetite-control system. It does not appropriately stimulate
insulin, which in turn does not suppress ghrelin (the hunger hormone)
and doesn’t stimulate leptin (the satiety hormone), which together
result in you eating more and developing insulin resistance and
eventually, diabetes.
Fructose rapidly leads to weight gain and
abdominal obesity (beer belly), decreased high-density lipoprotein —
the good cholesterol, increased low-density lipoprotein — the bad
cholesterol, elevated triglycerides, elevated blood sugar, and high
blood pressure — i.e. classic metabolic syndrome X.
