Introduction: Lactose intolerance is defined as the incapacity of the human body to digest the disaccharide sugar molecule‚ lactose. Lactose is a common carbohydrate found primarily in milk and associated dairy products. This widely known gastrointestinal disorder is typified by symptoms like nausea & vomiting‚ bloating‚ flatulence‚ abdominal pain and even diarrhoea. Lactose intolerance is a non-fatal disorder of the gastrointestinal tract. It is simply a nuisance and relatively harmless in and
Premium Milk Lactose intolerance
The lactose is milk sugar‚ a disaccharide consisting of one glucose and one galactose. When lactose reaches the small intestine‚ the lactase enzyme acts on the lactose found in ingested food‚ dividing it into the two molecules that compose it‚ so they can be absorbed‚ digested and transported through the bloodstream. When the person has a lactase deficiency (lactase enzyme has a low concentration or does not occur)‚ the dietary lactose cannot be digested in the small intestine directly passing into

Introduction • Lactose intolerance is actually a very common condition. People will lactose will experience digestive problems when they eat the main sugar found in milk and dairy products. People can acquire lactose intolerance at any point in their life. This can have a negative effect on the quality of life. Causes • Lactose intolerance takes place when your small intestine doesn’t produce enough of an enzyme called lactase to digest milk sugar called lactose (Lactose intolerance Causes‚ 2016)

Lactose is a complex found in all milks that is commonly used as an ingredient in lots of foods. Some people are unable to digest this lactose and it causes many problems for them. This is known as being lactose intolerant. The people that are unable to digest lactose body’s do not contain enough of the enzyme lactase which breaks down the lactose into simple sugars (glucose and galactose). When a person that is lactose intolerant consumes lactose‚ the undigested lactose passes through the small

Nutrition: Barriers to Digestion Lactose Intolerance: - Lactase is one of the many enzymes required for complete digestion of lactose (a disaccharide). - Lactose intolerance is not an allergy‚ and is not to be confused with a milk allergy‚ which initiates an immune reaction when milk is ingested. Lactose intolerance instead is an enzyme deficiency (lactase). - S/s including gas‚ bloating‚ cramping‚ nausea‚ and diarrhea. Some people can ingest small amounts‚ and others none. Some can take

Being lactose intolerant means that people cannot digest lactose products properly. This condition effects people at all different levels. The symptoms being shown with this are bloating‚ diarrhea‚ gas‚ and nausea. This condition is due to the large intestine not being able to break down the lactose into glucose‚ because of the lack of enzyme lactase. In order for the large intestine to work properly it needs certain dairy products such as yogurt to help with digestion. When a person id lactose intolerant
