Insulin resistance makes it harder for
glucose to be absorbed. Insulin is produced in the pancreas and is a
hormone that helps the body absorb glucose, keeping blood sugar
levels in balance.
Insulin resistance causes problems for
muscles, fat, and the liver, as they need glucose (sugar). Over
time, insulin resistance can cause high blood sugar levels and damage
cells.
Insulin resistance can lead to type 2
diabetes. People with insulin resistance are often diagnosed with
prediabetes. They may need extra checks to make sure they don't
develop diabetes.
Diet and other lifestyle choices can
increase the risks related to insulin resistance. Making diet
changes can reduce insulin insensitivity. This reduces the risk of
type 2 diabetes and the health problems that go with it.
Glucose is a vital source of energy for
the body. However, many of the body's cells can't absorb glucose on
their own. The pancreas secretes insulin into the bloodstream. It
joins up with glucose, and travels to the body's cells, where it
attaches to insulin receptors. Insulin allows the cells to absorb
glucose, making sure that:
- blood sugar levels remain at a safe level
- muscle, fat, liver, and other cells are able to get energy
Insulin resistance makes cells less
sensitive to insulin. This means the body has to produce more
insulin to keep blood sugar levels healthy.
If the pancreas is unable to keep up
with the increased demand for insulin, blood sugar levels go up.
When this happens, cells can't use all of the excess glucose in the
blood. This leads to type 2 diabetes.
The pancreas releases insulin to help
the body absorb glucose and maintain healthy blood sugar levels.
Following a healthful diet plan, such
as the Mediterranean Diet, can improve insulin sensitivity.
This diet recommends eating lots of
seasonal plant-based foods, having fruit as a dessert, and olive oil
as the main source of fat. Fish, poultry, and dairy products should
be eaten in moderation. It also advises people to have a very small
amount of red meat and a little wine during meals.
How many calories you have each day
should be based on weight loss goals and body size. Larger people
need more calories, while smaller people need fewer calories.
Generally, 2,000 calories per day is a healthy average to maintain
weight.
The Mediterranean Diet is just one
option for healthful eating. Other diet plans offer more specific
ways to improve symptoms of insulin resistance.
One of the simplest ways to tackle
insulin resistance is to eat foods with a low glycemic index (GI).
Low GI foods are digested slowly and
don't produce as many blood sugar spikes. The difference between low
GI and other foods is particularly noticeable when it comes to
carbohydrates. Carbohydrates that have a high GI can cause blood
sugar spikes and put more demand on the pancreas to make insulin.
As such, eating low GI foods is a good
way to maintain balanced blood sugar levels.
