Diabetes
is a growing health problem globally and nationally. The Centers For Disease
Control report 29 million Americans have it and a third of Americans (86
million) with pre-diabetes are close to getting it.
If
it's in your family, you may be worried you're destined to come down with this
dreaded disease. But is it an unavoidable part of your future? And if
you've already been diagnosed with this blood sugar problem - are you stuck
with it for good?
The
answer to these questions is "no".
Ultimately,
you have many choices for how you contend with this disease. And by making
strategic decisions and taking action accordingly, you can keep diabetes out of
your life without the use of medications.
While
there is a genetic predisposition for both type 1 and type 2 diabetes, you are
not destined to develop diabetes simply because it runs in your family. And if
you have it already, you don't have to live with it for the rest of your life.
In
fact, increasingly, evidence is showing that the best way to prevent diabetes,
to manage it and even to reverse it is not through medical intervention. The
best strategy for keeping diabetes out of your life includes exercise and a
simple shift in diet.
But
before we get into how to keep this dreaded disease out of your life, let's get
clear on what diabetes is...
Diabetes
And Blood Sugar Metabolism
Sugar
or glucose (carbohydrates broken down to their simplest form) is the fuel we
use for energy. We need sugars to live. When you're healthy, as soon as sugar
enters the bloodstream after your digestive system breaks down carbohydrates or
sugar, your body produces the hormone insulin. Insulin signals your cells to
take the sugar out of the bloodstream and bring it inside the cells where it
can be burned as fuel.
When
you have diabetes, for one reason or other, this process isn't working right.
For some people it's because their pancreas isn't producing enough insulin.
Without insulin, your cells don't take in sugar. Other people may produce
insulin. But their cells no longer respond adequately to insulin's signal.
As
a result, your body cannot use sugar effectively. This sugar continues to
circulate in the bloodstream and build in concentration. As it circulates, the
sugar interacts with proteins throughout your body to make advanced glycation
end products (AGEs).
These
sugar-protein complexes wreak pure havoc on your body. They spread a path of
destruction in your kidneys, your arteries, your eyes, your nerves and your
brain. Hence, with diabetes comes all kinds of related health issues like
kidney failure, arteriosclerosis, cataracts, Alzheimer's and more.
Scientist
agree there is some genetic predisposition for both type 1 and type 2 diabetes.
But
genes are only one of many different factors that determine if you have
diabetes... if it progresses... and even if you can get rid of it.
For
type 1 diabetes, in identical twin studies, only half of the twins developed
type 1 diabetes like their twin. Researchers believe breastfeeding in infancy,
viruses and even environmental factors like exposure to excessive cold can
influence whether a genetic predisposition develops into diabetes.[1]
When
it comes to type 2 diabetes, family clearly plays a significant role in whether
you develop it. But while family may influence whether you get diabetes or not,
it's not clear how much genes are at play here.
The
most significant risk factor for type 2 diabetes is obesity. And while there
may be some genetic predisposition towards obesity, researchers also point to
how family determines lifestyle choices - from familiar foods to how much we
exercise.[2]
By
breaking these family habits - or other bad ones we've accumulated over our
life - we can also break diabetes' hold on our lives. More and more evidence
shows that you have an extraordinary ability to determine how much this disease
becomes part of your life. According to the World Health Organization,
lifestyle choices can decrease the risk of progression of diabetes by as much
as 60%. Importantly, this is significantly more powerful than oral medications
which can only reduce the risk of progression by 30%.[3]
The
Power Of Lifestyle Choices
Exercising
and making good diet choices helps combat diabetes in two very dramatic ways.
Simply
put, when you exercise, your cells need fuel in the form of glucose. Because
they need fuel, your cells respond much more dramatically to insulin, taking in
as much glucose from the bloodstream as they can get.
A
few studies have demonstrated that high intensity exercise especially - as
little as 10 minutes a day - can dramatically increase your body's insulin
sensitivity. A review of eight studies found that a short bout of high
intensity exercise could reduce blood glucose levels for 1-3 days![4]
When
it comes to diet, the evidence is even more compelling...
Essentially,
when you eat lots of carbohydrates (grains and sugars), your body has to pump
out extraordinary amounts of insulin to contend with the flow of glucose into
the blood.
When
your body is put under this kind of pressure it either stops producing insulin
as effectively or stops listening to it.
However,
if you switch how you eat and stop loading your body down with carbohydrates,
you can shift all this. Instead of being overwhelmed by a flood of sugar
hitting the bloodstream, you'll be getting just enough. And with less sugar to
process, your body can respond in a healthy normal way.
The
research supporting this approach is powerful. For example, one study showed
how patients struggling with both obesity and type 2 diabetes saw extraordinary
changes when they went on a low carbohydrate diet. Their blood sugar levels
returned to normal and their body's responsiveness to the hormone insulin
increased by 75%![5]
This
growing body of research on low-carb diets and diabetes has caused many health
professionals to urge a shift in approach to diabetes care. In July 2014, a
consortium of 25 physicians and nutritionists published an article in the
journal Nutrition advocating a low-carb diet as the recommended first
line of attack in treating both kinds of diabetes.
As
Barbara Gower, Ph.D., professor and vice chair for research in the UAB
Department of Nutrition Sciences and one of the study authors explains,
diabetes is a form of carbohydrate intolerance. "For many people with
Type 2 diabetes, low-carbohydrate diets are a real cure. They no longer need
drugs. They no longer have symptoms. Their blood glucose is normal, and
they generally lose weight."
Dr.
Gower underscores how ineffective low-fat diets have been in preventing obesity
and diabetes. She strongly advocates ditching the low-fat diet recommendations
for low-carb diet recommendations. "Reducing carbohydrates is the obvious
treatment. It was the standard approach before insulin was discovered and is,
in fact, practiced with good results in many institutions."
Switch
Your Gene Expression With Diet
On
face value it makes sense that as you eat less carbohydrates, your body has
less sugar to contend with and consequently, your risk for diabetes goes down.
But
switching your diet doesn't stop there. As researcher and biology professor at
Norwegian University of Science And Technology, Berit Johansen, has shown,
making this switch induces changes at the genetic level.
As
Johansen and her colleagues have documented, when people eat high-carb diets
they turn on genes linked to cardiovascular disease, dementia, type 2 diabetes
and cancer. And when these same people decreased the amount of carbohydrates
they eat and increased the calories they got from fat and protein - within
days - these genes start to switch off.
Simply
by eating differently, you can switch which genes are activated!
Some
specific foods have also been shown to help spur this kind of healthy genetic
expression.
In
one study, Japanese researchers had participants eat 8.5 g of chlorella over a
two months period. At the end of the time, participants had healthier fasting
blood glucose levels, lower body fat percentages and healthier cholesterol
levels than the subjects who didn't take chlorella.
Particularly
interesting, the researchers also observed several points where the gene
expressions linked to insulin production and fatty acid metabolism were altered
in people who ate chlorella.
You
Can Determine If Diabetes Becomes Part Of Your Life
The
threat of diabetes is real and it is frightening. It can change everything in
your life if it hits. But if diabetes runs in your family... or if your doctor
has given you a stern warning... Don't lose hope. You have the most effective
tools on earth for keeping this debilitating disease out of your life. In fact
these tools are more powerful than anything a doctor can give you. But it's up
to you to decide to use them.
Diet
and exercise have tremendous power to change how our body works and even how
our genes express themselves. Genes play a role in our health. But when it
comes down to it, we determine the final outcome.
