Carbohydrate digestion process -

When people do not have enough of the enzyme lactase, lactose is not sufficiently broken down resulting in a condition called lactose intolerance. The undigested lactose moves to the large intestine where bacteria are able to digest it. The bacterial digestion of lactose produces gases leading to symptoms of diarrhea, bloating, and abdominal cramps.

Lactose intolerance usually occurs in adults and is associated with a gene that is inherited and associated with ancestry from certain parts of the world. African Americans, Hispanic Americans, American Indians, and Asian Americans have much higher incidences of lactose intolerance while those of northern European descent have the least.

The severity of the symptoms depends on how much lactose is consumed and the degree of lactase deficiency. The first organ to receive glucose, fructose, and galactose is the liver.

The liver takes them up and converts galactose to glucose, breaks fructose into even smaller carbon-containing units, and either stores glucose as glycogen or exports it back to the blood. How much glucose the liver exports to the blood is under hormonal control and you will soon discover that even the glucose itself regulates its concentrations in the blood.

If needed for energy, glucose is released from the liver to the bloodstream, and on to cells that need it. Excess glucose is converted to glycogen in the liver and muscles and stored in those organs.

The glycogen stored in the liver maintains blood glucose between meals; muscle glycogen provides immediate energy to the muscle during exercise. Enzymes in the liver and muscles combine glucose molecules to form glycogen through a process known as glycogenesis.

Once the storage capacity of the liver and muscles is reached, excess glucose is stored as fat. Glucose levels in the blood are tightly controlled, as having either too much or too little glucose in the blood can have health consequences.

Glucose regulates its levels in the blood via a process called negative feedback. An everyday example of negative feedback is in your oven because it contains a thermostat. When you set the temperature to bake a dessert at °F the thermostat senses the temperature and sends an electrical signal to turn the elements on and heat up the oven.

When the temperature reaches °F the thermostat senses the temperature and sends a signal to turn the element off. The glucose thermostat is located within the cells of the pancreas.

After eating a meal containing carbohydrates, glucose levels rise in the blood. Beta cells in the pancreas sense the increase in blood glucose and release a hormone, insulin, into the blood. Glucose can be stored only in muscle and liver tissues. In these tissues it is stored as glycogen, a highly branched macromolecule consisting of thousands of glucose molecules.

Glycogen levels do not take long to reach their physiological limit and when this happens excess glucose will be converted to fat. Insulin has an opposing hormone called glucagon.

As the time after a meal increases, glucose levels decrease in the blood. Alpha cells in the pancreas sense the drop in glucose and, in response, release glucagon into the blood. Glucagon communicates to the cells in the body to stop using all the glucose.

More specifically, it signals the liver to begin glycogenolysis the break down of glycogen into glucose and release the stored glucose into the blood, so that glucose levels stay within the target range and all cells get the needed fuel to function properly.

If additional glucose is needed, glucagon will stimulate the production of new glucose from amino acids a process known as gluconeogenesis. Almost all of the carbohydrates, except for dietary fiber and resistant starches, are efficiently digested and absorbed into the body.

Some of these remaining indigestible carbohydrates are broken down by enzymes released by bacteria in the large intestine. The products of bacterial digestion of these complex carbohydrates are short-chain fatty acids and some gases.

The short-chain fatty acids are either used by the bacteria to make energy and grow, are eliminated in the feces, or are absorbed into cells of the colon, with a small amount being transported to the liver. Colonic cells use the short-chain fatty acids to support some of their functions.

The liver can also metabolize the short-chain fatty acids into cellular energy. The yield of energy from dietary fiber is about 2 calories per gram for humans, but is highly dependent upon the fiber type, with soluble fibers and resistant starches yielding more energy than insoluble fibers.

Since dietary fiber is digested much less in the gastrointestinal tract than other carbohydrate types simple sugars, many starches the rise in blood glucose after eating them is less, and slower.

There are a few reasons this can happen: Lactose intolerance occurs when your body does not produce enough lactase, the enzyme that digests lactose, a milk sugar.

Lactase deficiency can happen naturally with age primary lactase deficiency , through injury to the small intestine secondary lactase deficiency , or due to genetics congenital lactase deficiency. However, in rare cases, babies may be born with congenital lactase deficiency.

Infants with this inherited condition are unable to digest the lactose found in breast milk or formula and must be given a lactose-free infant formula instead. Congenital Sucrase-Isomaltase Deficiency CSID is an inherited disorder that results in absent or low levels of sucrase and isomaltase.

Working with a registered dietitian, people with CSID may need to limit starches in their diet and slowly reintroduce them to determine tolerance. This disorder is rare, and symptoms can range from mild to severe depending on how much enzyme activity individuals have in their small intestine.

FODMAP sensitivity refers to a decreased ability to digest foods containing small chain carbohydrates in the small intestine. For people with FODMAP sensitivity, the carbohydrates in these foods can cause discomfort due to excessive gas and water retention in the small intestine. Written By: Allison Cain, Dietetic Intern.

Remember that the inner wall of the small intestine is actually composed of large circular folds, lined with many villi, the surface of which are made up of microvilli.

All of this gives the small intestine a huge surface area for absorption. Digestion and absorption of carbohydrates in the small intestine. Fructose and galactose are converted to glucose in the liver. Once absorbed carbohydrates pass through the liver, glucose is the main form of carbohydrate circulating in the bloodstream.

Instead, bacteria living in the large intestine, sometimes called our gut microbiota, ferment these carbohydrates to feed themselves. Fermentation also produces short-chain fatty acids, which our large intestine cells can use as an energy source.

Over the last decade or so, more and more research has shown that our gut microbiota are incredibly important to our health, playing important roles in the function of our immune response, nutrition, and risk of disease. A diet high in whole food sources of fiber helps to maintain a population of healthy gut microbes.

The primary goal of carbohydrate digestion is to break polysaccharides and disaccharides into monosaccharides, which can be absorbed into the bloodstream.

After eating, nothing needs to happen in the digestive tract to the monosaccharides in a food like grapes, because they are already small enough to be absorbed as is. Disaccharides in that grape or in a food like milk are broken down enzymatically digested in the digestive tract to monosaccharides glucose, galactose, and fructose.

Starch in food is broken down enzymatically digested in the digestive tract to glucose molecules. However, some dietary fiber is fermented in the large intestine by gut microbes.

Is this carbohydrate enzymatically digested? enzyme name. It is then transported to the liver where it is converted to glucose. This video will help you identify carbohydrates in foods, what carbohydrates need to be enzymatically digested, and what is absorbed.

Carbohydrates and Blood Sugar	Also, some nutrient-dense foods have higher GIs than less nutritious food. Chylomicrons leave the absorptive cells via exocytosis. A diet of low-GI foods has been shown in epidemiological and clinical trial studies to increase weight loss and reduce the risk of obesity, Type 2 diabetes, and cardiovascular disease. After digestive processes break polysaccharides down into monosaccharides, including glucose, the monosaccharides are transported across the wall of the small intestine and into the circulatory system, which transports them to the liver. Protein digestion is a multistep process that begins in the stomach and continues through the intestines.
Carbohydrate Digestion and Absorption - The Canadian Sugar Institute	Medical conditions that affect how carbohydrates are digested. The bottom line. Other tips Along with fruits and vegetables, fill your plate with whole grains instead of refined grains. These complex carbohydrate choices contain more fiber and key nutrients, like B vitamins. Watch for dairy products with added sugars. Low-fat milks, cheeses, and yogurts give the body needed calcium and protein, as well as other vitamins and minerals without the caloric load. Incorporate more beans, peas, and lentils into your day. Not only do these legumes provide you with complex carbohydrates, but they also boast impressive amounts of protein, folate, potassium, iron, and magnesium without a lot of fat. Read your labels. Always be on the lookout for added sugars, especially in processed foods. You should aim to get fewer than 10 percent of your calories each day from added sugars or simple carbohydrates.
