Lactose Intolerance
Lactose intolerance is the inability to digest significant amounts of
lactose, the predominant sugar of milk. This inability results from a
shortage of the enzyme lactase, which is normally produced by the
cells that line the small intestine. Lactase breaks down milk sugar
into simpler forms that can then be absorbed into the bloodstream.
When there is not enough lactase to digest the amount of lactose
consumed, the results, although not usually dangerous, may be very
distressing. While not all persons deficient in lactase have symptoms,
those who do are considered to be lactose intolerant.
The symptoms listed below are caused by the fermentation of lactose.
Since lactose is not broken into glucose, and hence left unabsorbed by
the body, the perfect conditions found in the intestines help the
lactose to ferment and this leads to the formation of gases. A
particular gas is methane that is usually the cause for the pain and
aggressive flatulence.
Common symptoms incl...
A healthy shake like Shakeology must be gluten free, right? Well, Shakeology gluten is a common concern among people who want to try this 'super shake'.
One of the most primitive actions known is the consumption of lactose, (milk), from the mother after birth. Mammals have an innate predisposition towards this consumption, as it is their main source of energy. Most mammals lose the ability to digest lactose shortly after their birth. The ability to digest lactose is determined by the presence of an enzyme called lactase, which is found in the lining of the small intestine. An enzyme is a small molecule or group of molecules that act as a catalyst (catalyst being defined as a molecule that binds to the original reactant and lowers the amount of energy needed to break apart the original molecule to obtain energy) in breaking apart the lactose molecule. In mammals, the lactase enzyme is present
Lactase is an enzyme found in the digestive system. It is essential to the complete digestion of sugar in whole milk and milk products. Lactase specifically breaks down lactose, a complex sugar. Lactase cannot be absorbed by the body unless it is broken down by lactase into glucose and galactose. According to webMD, “Lacking lactase in their intestines, a person consuming dairy products may experience the symptoms of lactose intolerance…Abdominal cramping, flatulence (gas) and diarrhea can occur when a lactose intolerant person consumes milk products.” ("Lactase Enzyme oral : Uses, Side Effects, Interactions, Pictures, Warnings & Dosing - WebMD", n.d.) Lactase is not recommended for use in CHILDREN younger than 4 years of age. Safety and effectiveness in this age group have not been confirmed. (Kluwer, 2014)
Lactose intolerance (LI) is the inability of some humans to digest the lactose sugar contained in most dairy products and foods made with dairy products. LI has numerous readily apparent physical symptoms such as gas, cramps and diarrhea (Houts 110). More importantly, LI may lead to malnutrition in those people affected because of the loss of milk's important nutrients. Not everyone is affected by LI. In fact, genetic background rather than any other health or cultural factor seems to best predict LI. The inability of humans to digest lactose has enormous health consequences, particularly among the poor populations of the U.S. and the developing third-world countries.
Celiac Sprue also known as celiac disease is a chronic disease of the digestive tract that interferes with the digestion and absorption of nutrients from food. (Mohaumed Wehbi, MD) also Celiac Sprue is an immune reaction to eating gluten a protein found in wheat, barley and rye. Due to the intestinal damage and malabsorption celiac sprue can reduce the quality of life due to diarrhea, fatigue weight loss, bloating, and anemia. The lining of the intestine contains essential enzymes for the absorption and digestion, its destruction leads to malabsorption, a difficulty in absorption of food and essential nutrients.
That is when muscles switch from aerobic respiration to lactic acid fermentation. Lactic acid fermentation is the process by which muscle cells deal with pyruvate during anaerobic respiration. Lactic acid fermentation is similar to glycolysis minus a specific step called the citric acid cycle. In lactic acid fermentation, the pyruvic acid from glycolysis is reduced to lactic acid by NADH, which is oxidized to NAD+. Lactic acid fermentation allows glycolysis to continue by ensuring that NADH is returned to its oxidized state (NAD+). When glycolysis is complete, two pyruvate molecules are left. Normally, those pyruvates would be changed and would enter the mitochondrion. Once in the mitochondrion, aerobic respiration would break them down further, releasing more
Gluten is a protein found in common grains such as wheat, barley, and rye. Those affected with allergies to these foods (the most serious allergy being Celiac Disease) must follow a strict gluten-free diet in order to experience relief from their symptoms. Despite eliminating the ingestion of the allergen, gluten-free individuals begin to suffer from adverse side effects. In recent years, many Americans have begun to live an entirely gluten-free lifestyle with no medical necessity to do so. Many believe it to be a healthier diet, and even more believe it is an effective weight-loss tool. With this growing fad of adopting a gluten-free diet, under the false pretenses of varying health benefits, many Americans are exposing themselves to unnecessary health risks, over-priced and narrowly available foods, and an overall depletion of dietary needs.
In dairy products and in milk, there is a sugar known as lactose. In order to digest this sugar, you need the necessary enzyme. There are several different reasons for the inability to digest lactose: primary lactase deficiency, secondary lactase deficiency, congenital lactase deficiency, and developmental lactase deficiency. Cases dealing with primary lactase deficiency are most common. As babies, there are normally more lactase enzymes produced than needed in order to digest lactose. “Worldwide, most humans lose 90% to 95% of birth lactase levels by early childhood, followed by a continuing decline during the course of a lifetime,” (Thorn). By the time children reach about three years old, the production of lactase significantly drops. In some...
Lactose intolerance is an inherited condition as indicated by a recently distributed survey, as well as complied research that has been collected. The survey results had only a small fraction of people who were lactose intolerant, 10%. However, almost 50% of survey takers family members had intolerance toward lactose. This proves several people are not born with the lactose intolerance activated but eventually with age the trait will activate since it has been inherited. Also majority of the survey takers are North American or European and in high school. Ethnicity, culture and age all have a large impact on whether or not the lactase enzyme is being produce, specifically in mammals.
Duarte Galactosemia is the second form. This form is when there is only a partial loss of the enzyme. The activity is usually 25%-50% that of a normal child. A child can get this form of galactosemia by inheriting a classic galactosemia gene from one parent and a duarte gene from the other. Much like classic galactosemia, duarte is found through a test done soon after birth. A strict diet is not needed for this form of the disorder. Instead a diet, it is recommended that lactose be slowly introduced untill normal consumption is accepted by the body. Because the affected can still process the foods, just not as well as a fully functional body.
Bright red flashing lights encircle the E.R. driveway as sirens screech to a halt. “EMERGENCY, EMERGENCY” codes are repeated over the intercom system of the endless pale colored hallways of the hospital. Doctors and nurses scurry full speed ahead in hopes to stop an allergic reaction. For people who suffer from food allergies, eating in restaurants is not a simple task. In our fast pace society, many restaurants often don’t consider or understand the seriousness when customers request substitutions or inquire about ingredients. Over the last two decades hospital admissions have increased due to people having anaphylaxis shock that have occur from eating foods they are allergic to in restaurants (Han 10). Anaphylaxis shock is a type of reaction when one’s body doesn’t agree with a certain substance. These reactions can often range from mild to extreme and life-threatening. These types of repercussions have caused the general public and businesses to become aware and knowledgeable about food allergies. Overtime, an abundance of people have developed sensitivities to various types of food, today there are approximately 15 million Americans with food allergies (Keefer). This vast increase has caused many restaurants to make extensive changes when it comes to their kitchens and menus. Not since recently have restaurants started to familiarize themselves on the topic of food allergies. Food allergies have developed and evolved all across America, generating substantial changes in the food industries.
The first is that it may be because of a weakened lower esophageal sphincter or LES. This is the valve that keeps the stomach acid inside the stomach and prevents the acid from coming in contact with the esophagus. A weakened LES is one of the most common symptoms of GERD or Gastroesophageal Reflux Disease.
Lactase, a type of enzyme usually found in the small intestine, breaks down lactose into sugars such as galactose and glucose. People that are lactose intolerant cannot consume anything containing dairy because they cannot break down lactose, a sugar found in milk. Those that are lactose intolerant lack the enzyme lactase. Without lactase, the body does not have the ability to break down lactose, which leads to a person having an upset stomach and diarrhea. Adults are more likely to be lactose intolerant than children because of the metabolic change in the body (Dritsas). The lack of lactase that people have can be compensated by taking pills to help break down lactose that is consumed; with the help of a lactase pill the body can now absorb galactase and glucose properly (McCracken, 481).

Certain nutrients such as calcium, iron, vitamin A and vitamin C are needed to digest sugar, and therefore too much sugar depletes these nutrients from the body [12]. This depletion results in anaemia and a lower immune system [12].
