How Does The Body Make Glucose?

Glucose mainly comes from foods rich in carbohydrates, like bread, potatoes, and fruit. As you eat, food travels down your esophagus into your stomach. There, acids and enzymes break it down into tiny pieces. During that process, glucose is released. It goes into your intestines where it's absorbed. From there, it passes into your bloodstream. Once in the blood, insulin helps glucose get to your cells. American Diabetes Association: "The Liver's Role: How It Processes Fats and Carbs."

    can the body produce its own glucose

    hi all
    i am interested to learn if the body can produce its own glucose, or does all the glucose come from what we eat.

    I guess,it does produce.Have u heard of stress elevating sugar levels? It is true.Stress,trauma & anxiety do elevate glucose levels whether u have eaten carb or not.

    The laws of physics dictate that we cannot make energy from nothing. But your body can create glucose from other things (fats and proteins) This is called gluconeogenesis (creating new glucose).
    So the answer to your question is yes the body can produce it's own glucose but also yes it all comes from what we eat, (we also eat fats and proteins)

Four Grams Of Glucose

Department of Molecular Physiology and Biophysics and Mouse Metabolic Phenotyping Center, Vanderbilt University School of Medicine, Nashville, Tennessee Department of Molecular Physiology and Biophysics and Mouse Metabolic Phenotyping Center, Vanderbilt University School of Medicine, Nashville, Tennessee Address for reprint requests and other correspondence: D. H. Wasserman, Light Hall Rm. 702, Vanderbilt Univ. School of Medicine, Nashville, TN 37232 (e-mail: [email protected] ) Received 2008 Jul 7; Accepted 2008 Oct 1. Copyright 2009, American Physiological Society This article has been cited by other articles in PMC. Four grams of glucose circulates in the blood of a person weighing 70 kg. This glucose is critical for normal function in many cell types. In accordance with the importance of these 4 g of glucose, a sophisticated control system is in place to maintain blood glucose constant. Our focus has been on the mechanisms by which the flux of glucose from liver to blood and from blood to skeletal muscle is regulated. The body has a remarkable capacity to satisfy the nutritional need for glucose, while still maintaining blood glucose homeostasis. The essential rol Continue reading >>

How Our Bodies Turn Food Into Energy

All parts of the body (muscles, brain, heart, and liver) need energy to work. This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose. The stomach and small intestines absorb the glucose and then release it into the bloodstream. Once in the bloodstream, glucose can be used immediately for energy or stored in our bodies, to be used later. However, our bodies need insulin in order to use or store glucose for energy. Without insulin, glucose stays in the bloodstream, keeping blood sugar levels high. Insulin is a hormone made by beta cells in the pancreas. Beta cells are very sensitive to the amount of glucose in the bloodstream. Normally beta cells check the blood's glucose level every few seconds and sense when they need to speed up or slow down the amount of insulin they're making and releasing. When someone eats something high in carbohydrates, like a piece of bread, the glucose level in the blood rises and the beta cells trigger the pancreas to release more insulin in Continue reading >>

    Insulin is a hormone made by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use. Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia). The cells in your body need sugar for energy. However, sugar cannot go into most of your cells directly. After you eat food and your blood sugar level rises, cells ...

    Gluconeogenesis (GNG) is a metabolic process of making glucose, a necessary body fuel, from non-carbohydrate sources such as protein (amino acids), lactate from the muscles and the glycerol component of fatty acids. Blood glucose levels must be maintained within a narrow range for good health. If blood sugar is too high, it results in tissue and organ damage. If it is too low, cellular respiration and energy production can suffer, especially if t ...
