lactose and by
Some studies in the U. S. and elsewhere suggest that milk consumption by lactose intolerant individuals may be a significant cause of irritable bowel syndrome.
Beyond infancy, individuals affected by CLD usually have the same nutritional concerns as any lactose intolerant adult.
To assess lactose intolerance, intestinal function is challenged by ingesting more dairy products than can be readily digested.
This may be done in diagnosis by giving lactose-free milk, producing no symptoms in the case of lactose intolerance, but the same reaction as to normal milk if it is a milk allergy.
If the lactose cannot be digested, enteric bacteria metabolize it and produce hydrogen, which, along with methane, if produced, can be detected on the patient's breath by a clinical gas chromatograph or compact solid-state detector.
If the lactose cannot be digested, blood glucose levels will rise by less than 20 mg / dL.
Since lactose intolerance poses no further threat to a person's health, the condition is managed by minimizing the occurrence and severity of symptoms.
Commercial cheese brands, however, are generally manufactured by modern processes that do not have the same lactose reducing properties, and as no regulations mandate what qualifies as an " aged " cheese, this description does not provide any indication of whether the process used significantly reduced lactose.
Carbohydrates are classified by their number of sugar units: monosaccharides ( such as glucose and fructose ), disaccharides ( such as sucrose and lactose ), oligosaccharides, and polysaccharides ( such as starch, glycogen, and cellulose ).
The lac operon is regulated by several factors including the availability of glucose and lactose.
The common disaccharides lactose and maltose are directly detected by Benedict's reagent, because each contains a glucose with a free reducing aldehyde moiety, after isomerization.
Because whey contains lactose, it should be avoided by those who are lactose intolerant.
In humans, this can be due to incomplete digestion of carbohydrate-containing foods, including milk and other dairy products ( lactose intolerance or the use of α-glucosidase inhibitors by diabetics ), gluten ( protein in wheat, barley, and rye ) ( celiac disease ), fruits, vegetables, beans, legumes, and high-fiber whole grains.

The explanation is that processing of lactose to allolactose ( catalyzed by β-galactosidase ) is needed to produce the inducer inside the cell.
The key idea is that proteins are not synthesized when they are not needed --- E. coli conserves cellular resources and energy by not making the three Lac proteins when there is no need to metabolize lactose, such as when other sugars like glucose are available.
In particular, it is determined whether LacZ and LacY are made even in the absence of IPTG ( due to the lactose repressor produced by the mutant gene being non-functional ).
