Nutritional Diseases and Insulin Resistance
Insulin Resistance Must Not Be Ignored
Insulin resistance is the result of modern nutritional diseases and it affects all developed countries which have improved economic status. Almost all of type II diabetes patients, as well as those who have high blood pressure, and cardiovascular disease, have this affliction.
Perhaps 20-25% of the healthy population have above average insulin levels in their blood. In the US these conditions are the leading contributors to disease and mortality.
Insulin resistance is the condition in which normal amounts of insulin are inadequate to produce a normal insulin response from fat, muscle and liver cells. In fat cells, instead of taking up glucose, fat is hydrolyzed and released into the blood stream as free fatty acids. Insulin resistance in fat cells results in hydrolysis of stored triglycerides, which elevates free fatty acids in the blood plasma.
Insulin resistance in muscle reduces glucose uptake, whereas in the liver glucose storage is reduced. Both effects serve to elevate blood glucose. High plasma levels of insulin and glucose due to insulin resistance often lead to metabolic syndrome and type 2 diabetes.
Metabolic syndrome is a combination of medical disorders that increase the risk of developing cardiovascular disease and diabetes.>
It affects a large number of people, and prevalence increases with age. Some studies estimate the prevalence in the USA to be up to 25% of the population.
Metabolic syndrome is also known as metabolic syndrome X, syndrome X, insulin resistance syndrome, Reaven's syndrome or CHAOS (Australia).
How Do You Know if you insulin resistance?
No outward signs may determine whether an individual is insulin resistant. A glucose tolerance test and test for insulin levels are necessary to determine this syndrome.
Many healthy individuals who are insulin resistant are able to put out enough insulin to keep their glucose levels in an acceptable range.
It is stated that no one knows for sure what causes high levels of insulin in the blood. Some scientists wonder if a defect in a gene may cause this condition and resulting diabetes.
What we do know is that insulin resistance is aggravated by obesity and physical inactivity both of which are increasing in the U.S.
It is known what will cure insulin resistance and what is needed to keep it at bay. It is also known that these symptoms were rare 50 to 60 years ago.
By maintaining an appropriate weight and a physically active lifestyle many individuals are able to reduce their chances of developing insulin resistance and diabetes.
All people with insulin resistance do not develop diabetes. Science has not yet determined why some people with insulin resistance eventually develop diabetes and others do not.
Insulin Resistance often leads to obesity. Learn about this health concern.
Consider ways to control obesity and insulin resistance. Read the review of The Fat Loss Bible.
