Mechanism's For Controlling Blood Sugar Levels:
The blood glucose level is the amount of sugar or glucose in the blood that is also referred to as plasma glucose level and expressed as millimoles per litre. While blood glucose levels are measured in order to diagnose and monitor diabetes, it's also important to monitor these levels in certain situations, especially with increasing age and during pancreatitis and pregnancy. Under normal circumstances, blood sugar levels usually stay within a daily narrow limit of between 4 and 8 millimoles per litre. In addition, the levels of blood glucose in the body are usually higher after meals and lowest in the morning. Nonetheless, the body has certain mechanisms that help in controlling blood glucose levels under normal and stress conditions.
The body basically maintains a minimum level of glucose in the blood and also limits surges of glucose after a meal by about 70 mg/dl and not to exceed 140 mg/dl respectively. Generally, the level of glucose in the blood is regulated by hormones secreted through the islets of Langerhans in the pancreas. Islets play a crucial role in this process since they consist of alpha cells and beta cells that produce glucagon and insulin respectively (Zamora, 2012).
When the blood glucose level increases after a meal, the beta cells discharge insulin to enable the conversion of glucose to glycogen and fat. As a result, the blood glucose level returns to normal after the glucose has either been burned or stored as fat or glycogen. However, when the blood glucose level...
In addition to being known as bulk or roughage, dietary fibers cannot be digested by the body unlike other food components like carbohydrates, fats, and proteins. The dietary fiber instead passes relatively unbroken through the stomach, colon, small intestine, and out of the body. These food components are divided into two major categories i.e. soluble fibers and insoluble fibers.
As the name suggests, soluble dietary fibers dissolve in water to create a gel-like substance that helps in lessening the blood glucose and cholesterol levels. The most common food sources of soluble dietary fibers include beans, some fruits and vegetables, oat, nuts, barley, peas, lentil, and psyllium. While the certain kinds of soluble fibers help in lowering the level of cholesterol, its effect on heart disease is still uncertain. On the contrary, insoluble dietary fiber is a type of fiber that enhances the movement of substances through the digestive system and increases stool bulk. As a result, insoluble dietary fiber can be beneficial to people with problems of constipation or irregular stools ("Dietary Fiber: Essential for a Healthy Diet," n.d.). The most common food sources for insoluble dietary fibers include wheat bran, whole-wheat flour,…
