Whole-food salad full of fibre to help regulate insulin levels. |
We’ve all heard of insulin, but perhaps only in relation to diabetes. However, there is now increasing awareness of the important role this hormone plays for all of us, not only in transporting blood sugar around the body, but in fat storage and disease as well.
When you eat sugar or carbohydrates (that
convert to sugar in the body) your pancreas releases insulin to get the sugar
out of the bloodstream. Well-done body. This is a very important job, as high
blood sugar is dangerous, and potentially deadly without such clever
regulation. But what happens if insulin is overworked as a result of our sugar
and carb laden modern diet?
Basically what happens is that once insulin
has stored as much sugar as will fit in the muscle and liver cells, it has no
option but to store it as fat. At the same time, insulin stops the body burning
fat because it needs to focus on the immediate issue of using sugar for energy.
The problem with our modern diet is that so
much of our food is refined and full of sugar that it causes a massive roller
coaster of high and low blood sugar levels. If we eat whole food carbs full of
fiber, the sugar will be released more slowly into the bloodstream than if
you’re eating white rice or donuts. When the blood is flooded with sugar (from
any source, even “healthy” sugars), the body responds quickly with
insulin.
But in a desperate attempt to shuttle that
sugar away from our blood, there can be some overcorrection. Then the blood glucose
levels get too low and the body screams out “quick, feed me some more sugar”.
And that’s when you get that little message from your brain saying “ooh snack
time”. And it’s usually a sugar-laden snack, because that’s what your body is
telling you it needs… and now!
An image that really stuck in my mind from my nutrition studies is the analogy of insulin as a fast car overcorrecting as it swerves around a corner. When the “car” realizes it’s gone too far, the driver quickly turns hard in the opposite direction. But what happens if the turn is so great that you run off the road?
Over time, if this yo-yoing of insulin
continues, your body’s cells can become resistant to insulin and need even more
to have the same effect. Welcome Type 2 diabetes. Unlike Type 1 diabetes, in
which your body cannot produce insulin at all, Type 2 diabetes is more common
and an ever-increasing problem in the world of fast food. In this type of
diabetes, the body’s cells may become resistant to insulin and/or not produce
enough insulin. The consequences are far from pleasant if you value your heart,
brain, eye-sight and keeping your feet attached to your body!
So what is the take home message? Cut out sugar and refined carbohydrates from your diet, eat wholefoods and don’t forget healthy fats to fill you up and replace the empty carb calories that cause disease.
Get off that insulin roller coaster and
glide towards wellness.
May
you always be full of beans and other wholefoods,
