relationship between insulin and glucose simple carbohydrate

If you have type 2 diabetes, you know that carbohydrates affect blood sugar. Find out the difference between simple and complex carbohydrates. As cells absorb blood sugar, levels in the bloodstream begin to fall. Simple carbohydrates are easily and quickly utilized for energy by the body because of However, the relationship between glycemic index and body weight is less well. Simple carbohydrates reach the blood directly and quickly and are responsible for a steep rise in sugar – in the form of glucose – in the blood.

Do not change your insulin type unless your health care provider tells you to. Check your blood sugar levels. Ask your health care provider what your blood sugar levels should be and when you should check them. Do not reuse or share your needles or syringes with other people. Serious side effects can lead to death, including: Some signs and symptoms include: Your insulin dose may need to change because of: What happens to excess glucose?

When you consume more carbs than necessary to meet energy requirements, the excess glucose has to be transported and stored somewhere.

Insulin helps convert the excess carbohydrate foods you eat into either glycogen the storage form of carbohydrate in the muscles or into fat stored in fat cells. How does that relate to fat buildup? Insulin promotes the storage of nutrients and simultaneously blocks the breakdown metabolism of protein, fat and carbohydrate in the body. When the insulin level rises, it puts the brakes on burning fat for fuel and simultaneously encourages fat storage. It is easy to imagine how this complexity in the biology of insulin action might lead to complexity in interpreting studies that try to examine the relationships between alterations in dietary composition and insulin action.

It seems unlikely that any simple relationship between a change in the composition of the diet and a change in insulin action will emerge. Rather, the effects of dietary changes on insulin action within specific groups that are most likely to experience adverse health effects should be sought. As detailed genetic information emerges on insulin resistance, this new information should be incorporated into nutritional studies.

Simple vs Complex Carbs

Macronutrient composition of the diet in insulin sensitivity When the relationship between a change in the diet and insulin sensitivity is examined, the first problem encountered is that any change in one component of the diet is accompanied by reciprocal changes in other components of the diet. When the effect of dietary carbohydrates on insulin action is examined, it is important to note what other changes are being made in the diet when carbohydrate is altered.

Early experiments in humans examined the effect on insulin action of altering the relative amounts of dietary carbohydrate and fat.

As far back asHimsworth found that the ability of insulin to lower blood glucose was improved as dietary carbohydrate increased. That is, a low carbohydrate, high fat diet was associated with a reduced ability of insulin to reduce plasmic glucose; conversely, a low fat, high carbohydrate diet was associated with an improvement in insulin's ability to stimulate glucose disposal. This general finding has been seen in animal studies and more recent human studies as summarized in the excellent review by Daly et al.

Using the euglycemic, hyperinsulinemic clamp method, Swinburn compared the effects of a high carbohydrate diet with a lower carbohydrate diet in Pima Indians 9. In this study, fasting insulin and glucose levels were improved despite no change having occurred in insulin action as measured by the hyperinsulinemic clamp. Recent epidemiologic studies have looked at the relationship between diet composition and the onset of type 2 diabetes, a relationship that may involve changes in insulin action as well as insulin secretion.

In the San Luis Valley study, no relationship was found between dietary carbohydrate and either hyperinsulinemia or the onset of frank diabetes In fact, there was a trend for an inverse relationship.

However, a significant relationship occurred between dietary fat and newly diagnosed cases of diabetes.

Carbohydrates and Diabetes

The strength of this study comes from its prospective design, careful diet histories and accurate case identification. Three other recent studies, the Health Professionals Follow-Up Study 11the Nurses Health Study 12 and the Iowa Women's Health Study 13looked at large populations of men and women and examined the relationship between diet composition and the onset of diabetes. These studies also failed to show a relationship between total carbohydrate intake and development of diabetes.

Most recently, Swinburn et al. Taken together, these data support the idea that high carbohydrate diets, at the very least, do not adversely affect insulin sensitivity and may be beneficial for insulin sensitivity. On the contrary, high intakes of dietary fat, particularly saturated fat, do appear in some of these studies to be associated with a decline in insulin sensitivity.

Simple sugars Simple sugars include the monosaccharides glucose, fructose and galactose and the dissaccharides sucrose, maltose and lactose. Many animal studies have examined the relationship between insulin action and high intakes of fructose and sucrose An exception to this finding is a study done in female rats that found no association between increased consumption of sucrose and insulin resistance In general, these studies have demonstrated that the adverse affects of sucrose and fructose are a function of the dose used and duration of exposure such that if a lower dose is used, the duration of exposure must be longer to produce the effect.

In addition, the effects of sucrose on insulin action appear to be less in older obese rats that already have a moderate degree of insulin resistance, and in rats that are already insulin resistant as a result of consumption of a high fat diet Fructose appears to be avidly taken up and metabolized by the liver.

This uptake and metabolism produce a metabolic state characterized by increased glucose uptake by the liver, which leads to a variety of cellular events, such as changes in the expression of the gluconeogenic enzymes that produce insulin resistance. Studies in humans examining the ability of dietary sucrose to produce insulin resistance have not been nearly as convincing 3.

Studies in both normal adults and adults with type 2 diabetes have fairly consistently shown no effect on insulin sensitivity of isoenergetic substitution of sucrose or fructose for starch.

Many of these studies had relatively few subjects and were of short duration. Isolated studies have shown adverse effects of dietary sucrose, but these are the exception rather than the rule. Both fructose and sucrose are associated with lower glucose excursions after ingestion, and some recommendations have even advocated the use of fructose as a beneficial sweetener for individuals with type 2 diabetes.
