BLOG 276 INSULIN
Insulin is the hormone that takes the glucose from the blood
and moves it to the cells for use for energy and for storage. We typically hear
about this topic in relation to diabetes. That is because people with diabetes have
high levels of insulin in their blood. As a result of this insulin imbalance,
either the body is unable to move it to the cells or upon arrival the cells
don’t respond to insulin as well as they should.
The key factor is glucose which comes from carbohydrate rich
foods. The main culprits are bread, potatoes, and fruit. Upon entering the
mouth, food then travels down the esophagus before entering the stomach. During
this traveling adventure, enzymes and acids from the foods are broken down into
tiny digestible pieces that release glucose. The intestines absorb the glucose
and then it hits the bloodstream. Now when in the blood, insulin kicks in to
pick up the glucose to take it to the cells.
We want glucose to keep at a constant level in our blood. There
are cells in the pancreas that monitor blood sugar levels. Naturally after
eating, blood sugar levels rise so the cells release insulin into the
bloodstream. Now insulin takes glucose to the muscles, liver, and fat of the
body to be used. The majority of this glucose is utilized by the body as
energy. Most notably, glucose is what the brain uses for energy. The cells of
the brain need glucose to help the chemical messengers be able to process information.
The body uses what it needs, then the extra glucose gets stored in the liver
and muscles as glycogen.
When you don’t eat, blood sugar levels drop. The pancreas
doesn’t release insulin. The cells in the pancreas start to make glucagon. The
role of this chemical is to tell the liver to start to break down glycogen that
has been stored to be used as glucose. Then the glucose is released to the
bloodstream until you finally eat again.
Type 1 diabetes occurs when the body does not have enough
insulin. Insulin is made in the pancreas, but the body is attacking the cells
needed for this production. For type 2 diabetics, the cells don’t respond to
insulin appropriately. The pancreas has to work overtime to make enough insulin
to have it properly transported to the cells. The pancreas reaches its max and
then eventually becomes too impaired to make the amount of insulin the body
needs. Having too much insulin distorts the function of the vessels that carry oxygen
rich blood to the organs. Diabetics have to constantly be aware and test their
blood sugar levels. Complications can lead to stroke, heart attack, kidney
damage, and nerve damage.
The role of insulin in the body is pivotal to our health. The
best medicine is eating right and exercising. Diabetes can be genetically
related but for anyone can be a threat based on lifestyle choices, the impact
of eating whatever one desires can wreak havoc on your health. Moderation is the
key when it comes to carbohydrate consumption. The body needs this macronutrient
for brain power and energy, but eating more than needed won’t make you smarter,
quicker, faster, or stronger. Stability is a good thing and insulin being stable
and operating efficiently in the body is something everyone needs.
