What Is Glucose?

Glucose, also called dextrose. It is a sugar and a naturally occurring carbohydrate. The foods we eat containing glucose are broken down into sugar in our stomach and then absorbed into the bloodstream.

High glucose levels raise the blood sugar level, which can lead to health issues.

Glucose In Food

Glucose, also called dextrose, is a carbohydrate that is a primary source of energy for living organisms. It’s naturally occurring, found in fruits and other parts of plants. (source 🗗)

Glucose In The Body

Glucose is ingested and transported through the wall of the gut and into the blood. Once in the blood, glucose circulates throughout the body. The process of glucose uptake from the blood into the brain is not dependent on energy. (source 🗗)

The Release Of Insulin

When glucose circulates through the pancreas with increasing concentration, it stimulates the release of insulin.

There are two phases of insulin release in response when glucose ingests. First-phase insulin release occurs within 2 min. It leads to a sharp peak in plasma insulin, which then returns to normal levels within 10 minutes. If the exposure to glucose is prolonged, second-phase insulin release starts and will go on for a longer time. (source 🗗)

After ingestion of standardized meals with fast absorption, the glucose peaks fast and high. While meals with higher fiber, protein, and fat induce a smaller increase and slower decrease in glucose concentrations. (source 🗗)

Keep Glucose Leaves Low

High glucose levels raise the blood sugar level. When this is prolonged, it can cause problems.

It can lead to the development of insulin resistance or other health issues. (source 🗗)

Maintaining blood glucose concentration within an acceptable range is especially important for patients with diabetes. (source 🗗)
