Lactose intolerance

Rodrigues Bio 345 June 22, 2019 Lactose Tolerance and Human Evolution In the HHMI movie by Dr. Sarah A. Tishkoff, she explains how lactase persistence is an example of human adaption. Throughout her lecture she goes into detail about how lactose tolerance and lactose intolerance came to be, and how this adaption developed. In this paper I am going to address five specific questions that explain the adaption of lactose tolerance/intolerance in adult humans. The proximate mechanism that provides lactose tolerance in adult human is the activation of the lactase enzyme in our bodies. As children our bodies produced this active enzyme lactase (found in the small intestine), which allows for the breakdown of the sugar lactose that is present in milk. As adults this enzyme is shut off, but due to a genetic mutation in some people they “maintain the expression of this gene at…

m 20 March 2015 Hypolactasia Lactose intolerance, also known as hypolactasia, has become a huge epidemic over the years. This is a result of a genetically determined decline in the activity of lactase that begins in early childhood. Many people have suffered from this inability to digest lactose, which is found in milk and other dairy products. People who are lactose intolerant only have symptoms occur when they have dairy/milk products. These symptoms include bloating, cramps in the lower…

Lactose Intolerance Lactose intolerance is a metabolic issue when the body produces insufficient lactase enzymes in the small intestines to digest the lactose sugar found in dairy products. Fortunately, this condition doesn’t cause any physical damage, however, it can produce symptoms such as abdominal gas, bloating, diarrhea, pain, and nausea. The severity of these symptoms is directly proportional a person’s lactose intolerance, and the amount of lactose they consume. What is Lactose and How…

are considered to be lactose intolerant. Lactose intolerance is a common chronic digestive disorder in which a person’s intestinal tract lacks the ability to make lactase. It results from a drop in or disruption of the production of lactase in the small intestine. The small intestine is a primary part of the digestive system, and is the longest part of the gastrointestinal tract and makes up about three quarters of the digestive system. It is a hollow tube like organ that connects to the…

Lactose intolerance is the inability of the body to digest the sugar lactose, which is a sugar that is found in dairy products. While some people believe that lactose intolerance is an allergy to milk, it is not (Lactose Intolerance: Overview). A milk allergy is a disorder different from being intolerant to lactose. Adults or adolescence are more likely to develop lactose intolerance than children and it is a very common disorder worldwide (Lactose Intolerance: Overview). People of African or…

Treatment of lactose intolerance is only necessary if symptoms are present (Coutts, 2013). The main treatment of lactose intolerance is diet control which includes the exclusion of lactose from the diet with initial discontinuation of milk and cream (Coutts, 2013). Non-dairy milks such as soya, almond and lactose free milk that are calcium and vitamin D enriched should be utilized; higher calorie, protein and micronutrient enriched options should be selected over the lower calorie options…

Senior citizens or people with compromised immune systems may benefit from adding kefir to their daily diet. Even if immune system function does not drastically improve, kefir will increase overall energy and vitality. Kefir aids the digestion of lactose Kefir is also popular among those who are lactose intolerant. While it does contain dairy products, the bacteria and yeast in the kefir work together to form lactase, the enzyme needed to digest lactose. It is the lack of this enzyme that…

What is lactose intolerance? A common misconception that lactose intolerance is that it is just a diary intolerance. A lactose intolerance is the body’s inability to break down the sugar or lactose commonly found in dairy products. When someone is affected by lactose intolerance, all it means is that the patient's small intestine isn’t or stops making enough enzyme lactase to digest the lactose properly, the lactase then makes its way to the large intestine. The bacteria found in the large…

twenty minutes, when the skin starts to redden (American College of Allergy, Asthma, and Immunology, 2015). Scientists propose that some milk proteins like casein and whey are more injurious to individuals allergic or intolerant to milk or dairy products. Read labels carefully, make sure theres no casein, whey, lactose, or chocolate in the product before eating it (Mayo Clinic, 2014). Milk can be substituted very easily for an individual that cannot have a milk or dairy diet. Rice milk, soy…

more susceptible to lactose intolerance. For example the type of ethnicity one is, premature birth, diseases affecting the small intestine, and certain cancer treatments (Diseases and conditions Lactose Intolerance). Not only does being lactose intolerant prohibit one from consuming certain dairy delicacies but sadly that is not the worst part. That would be that there are no ways of testing if you are until you consume something dairy. After consuming a dairy product the unsuspecting and…
