and diabetes

It is now a well known and established fact that we are facing
a global pandemic of Diabetes Mellitus. Type 2 diabetes is
one of the fastest growing and most costly disorders worldwide.
Scientists report that at least 25 per cent of the population
are walking around undiagnosed and insulin resistant (the
latter is the syndrome just preceding diabetes). The sad news
is that the age bracket is sliding lower and lower.
Children are affected!!
Type 2 diabetes used to be called "adult-onset"
diabetes, because it mostly occurred in people over 50. But
no longer! The rising rate of diabetes in children is epidemic.
"If you go back 20 years, about two per cent of all cases
of new onset diabetes (type 2) were in people between nine
and 19 years old. Now, it's about 30 per cent to 50 per cent
" said Dr. Gerald Bernstein, an endocrinologist with
New York's Beth Israel Medical Center.
Among Americans in their 30s, the 1990s saw a 70 per cent
rise in type 2 diabetes, reports the CDC (Centre for Disease
Control). Other age groups also showed significant increases.
For those in their 40s the disease rose by 40 per cent, and
by 31 per cent for those in their fifties. It is also important
to note that blacks seem to be the most susceptible race in
America. A lot of developing countries are in the grip of
this global pandemic. While countries, like India seem to
be most adversely affected, Nigeria is now having an explosion
in the level of occurrence.
I was going to write a different topic today, but decided
to write on free radical damage with regards to diabetes,
because of a specific request by someone. I felt, it is a
topic that would benefit others so I decided to share it.
The statistics I quoted above show that there is serious cause
for concern. You may begin to wonder what is going wrong or
what are we doing wrong?
I and probably a lot of others have written exhaustively about
the predisposing factors. People usually do not bother and
feel insulated against ailments, like diabetes until a relative
or they themselves are diagnosed. It is important, to be well
educated about issues around you and adopt measures that will
reduce ones susceptibility as well as ensure a healthier lifestyle
for the diagnosed. People with a positive family history (i.e.
with one or both parents who have been diagnosed as diabetic),
should adopt lifestyles which would reduce the probability
of their developing the disease.
While free radicals is the focus for today in relation to
diabetes; I will briefly mention exercise, which is a very
important factor.
Inactivity: These days, more and more people are engaged in
blue collar jobs, which do not necessitate their working their
bodies. Nobody wants to be a labourer or a farmer. Nigerian
engineers are always teased about being in the office! These
days, it is literarily unheard of for anybody to trek to the
office. You either catch a bus and the more affluent drive
or are driven. The bottom line is that rich or poor, day in
day out, people sit on their buttocks to and from work. By
the time they get back from work at the close of day, they
are so tired that wild horses would not be able to drag them
to do any form of exercise!!
Children and adolescents are not spared. Not exercising, being
sedentary (watching TV, spending time on the computer, and
playing video games), and eating larger portions of foods
than they need take the lion's share of blame for the downward
age progression of the diabetes epidemic. It is very important
for people to arrange their lives in a way to increase the
amount of exercise they do. Start small. Easy to do activities,
like walking and dancing, can make a huge difference to tuning
the body for good health. Sports like tennis (table and lawn),
swimming, etc can be picked up with time. What are free radicals?
What do they have to do with diabetes?
What are free radicals? I will give the straight scientific
definition of free radicals which may be a bit difficult for
non-science oriented readers to understand. But that is what
free radicals are Free radicals are atoms or groups of atoms
with an odd (unpaired) number of electrons and can be formed
when oxygen interacts with certain molecules. Free radicals
are not completely bad. They are generated during normal biological
processes that take place within our body. In fact, they are
needed in vital body metabolic processes. The problem starts
when free radicals that the body cannot handle or neutralize
are generated. Some are xenobiotic or alien free radicals
to the body. Certain substances are potent free radical generators.
Once formed, these highly reactive radicals can start a chain
reaction. Their chief danger comes from the damage they can
do when they react with important cellular components, such
as DNA, or the cell membrane. Cells may function poorly or
die if this occurs. Now imagine that these cells are the cells
of an important organ, like the pancreas, which secretes insulin.
What do they have to do with diabetes? Free radical stress
has been implicated in the pathogenesis of both type 1 and
type 2 diabetes. Free radical stress would contribute to spontaneous
type 2 diabetes development. I had written about free radicals
in this column precisely in 2004 though not in specific relation
to diabetes. Despite this, I mentioned that free radicals
is the way a lot of substances and microbes exert their damage
on cells of the body.
Free radicals are implicated in a wide assortment of diseases.
With diabetes, some chemicals used in processing modern day
food are potent agents that exert free radical stress on the
pancreas. One of them is ALLOXAN, which is used to bleach
wheat and make flour white. While Parental stock is an important
determinant of susceptibility for glucose intolerance disorders,
it wise to adopt a lifestyle which ensures reduced exposure
to potent food toxins. In food toxins, I mentioned that we
eat toxins in our food everyday.
Some are used to preserve or process the food. The bottom
line is that certain substances can generate free radicals,
which increase the probability of developing type 2 diabetes,
especially in positively predisposed persons. It is important
to eat a diet that is low in such substances, but high in
antioxidants containing foods like fruits, vegetables, nuts,
etc. The latter help to neutralize free radicals before they
are able to exert any damage.
