Persons with lactose intolerance are unable to digest significant amounts of lactose because of a genetically inadequate amount of the enzyme lactase. Common symptoms include abdominal pain and bloating, excessive flatus, and watery stool following the ingestion of foods containing lactose. Lactase deficiency is present in up to 15 percent of persons of northern European descent, up to 80 percent of blacks and Latinos, and up to 100 percent of American Indians and Asians. A sizable number of… 
Knowledge of lactose intolerance among clinicians
TLDR
This work aimed at identifying gaps in knowledge regarding lactose intolerance among medical practitioners using a survey consisting of 15 questions, and highlighted acceptable knowledge of general issues, but not the diagnostic aspects, of lactose intolerant among doctors.
Lactose in processed foods: evaluating the availability of information regarding its amount.
TLDR
There is a low availability of information about the amount of lactose in processed foods, which is more available in the diet/light/zero food group.
Effect of exogenous β-galactosidase in patients with lactose malabsorption and intolerance: a crossover double-blind placebo-controlled study
TLDR
The study shows that in lactose malabsorbers with intolerance, the lactase obtained from K. lactis can represent a valid therapeutic strategy, with objective and subjective efficacy and without side effects.
Fatores Desencadeantes da Intolerância á Lactose: Metabolismo Enzimático, Diagnóstico e Tratamento
TLDR
The study aimed to describe the triggering factors of the LI, since it is an adverse reaction that reaches 70% of the world population, as well as diagnosis and treatment, and a literature review from the scientific databases in the period of 2004 to date.
The effect of oral supplementation with Lactobacillus reuteri or tilactase in lactose intolerant patients: randomized trial.
TLDR
In lactose intolerants, tilactase strongly improves both LBT results and gastrointestinal symptoms after lactose ingestion with respect to placebo and this probiotic may represent an interesting treatment option for lactose intolerance.
[Correlation between the presence and intensity of symptoms and the results of hydrogen breath tests in the diagnosis of carbohydrate intolerance].
TLDR
A correlation between symptom intensity and test positivity was found in patients with lactose intolerance and the presence of flatulence after lactose loading may be indicative of a positive test.

Crohn's disease (CD) is a well known chronic pathological condition whose aetiology has remained unrecognized for nearly a century. Complex immune mechanisms in a specific genetic background causing
Adaptation to milk drinking and evolution of lactase persistence in pastoralist goat herders in central-northern Chile
Milk contains lactose as source of energy, which is digested by intestinal lactase, an enzyme that declines after weaning. The genetic trait of lactase persistence (LP) evolved together with the
Review of Intolerance Reactions to Food and Food Additives
TLDR
An overview of the contemporary understanding of food intolerance is provided, and the individual nature of intolerance reactions and the wide range of food chemicals, whether naturally occurring or added to food, which may contribute to intolerance reactions are highlighted.
Clinical ramifications of malabsorption of fructose and other short-chain carbohydrates
ructose is a hexose that is present widely in thediet as free fructose, in the disaccharide, sucrose,and in fructans, which are chains of fructose witha terminal glucose. Fructans are also known as

A comparison of symptoms after the consumption of milk or lactose-hydrolyzed milk by people with self-reported severe lactose intolerance.
TLDR
When lactose intake is limited to the equivalent of 240 ml of milk or less a day, symptoms are likely to be negligible and the use of lactose-digestive aids unnecessary.
Lactose intolerance: problems in diagnosis and treatment.
TLDR
Symptom similarity and the resultant incorrect diagnosis of IBS may explain the refractory nature of some patients labeled as IBS who remain largely unaware of the relationship between food intake and symptoms.
When to suspect lactose intolerance. Symptomatic, ethnic, and laboratory clues.
TLDR
People who avoid dairy products should receive calcium supplementation and should be advised to read ingredient labels carefully, as some persons with normal lactase activity may become symptomatic on consumption of products containing lactose.
Allaying fears and fallacies about lactose intolerance.
TLDR
Scientific findings indicate that the prevalence of lactose intolerance is grossly overestimated and several dietary strategies are available to help lactose maldigesters include milk and other dairy foods in their diet without experiencing symptoms.
Tolerance to small amounts of lactose in lactose maldigesters.
TLDR
It can be concluded that the gastrointestinal symptoms in most lactose maldigesters are not induced by lactose when small amounts of lactose are included in the diet.
A randomized trial of Lactobacillus acidophilus BG2FO4 to treat lactose intolerance.
TLDR
Treatment of lactose-maldigesting subjects with and without hypochlorhydria with Lactobacillus acidophilus BG2FO4 for 7 d failed to change breath-hydrogen excretion significantly after lactose ingestion, and overreported lactose intolerance is overreported.
Colonic adaptation to daily lactose feeding in lactose maldigesters reduces lactose intolerance.
TLDR
There is colonic adaptation to regular lactose ingestion and this adaptation reduces lactose intolerance symptoms, and the sum of hourly breath-hydrogen concentrations was significantly reduced after the lactose feeding period compared with after the dextrose period.
Tolerance to the daily ingestion of two cups of milk by individuals claiming lactose intolerance.
TLDR
It is concluded that LNP subjects tolerate two cups of milk per day without appreciable symptoms, and S-LNP subjects have underlying flatulence that is misattributed to lactose intolerance.
Lactose maldigestion is not an impediment to the intake of 1500 mg calcium daily as dairy products.
TLDR
The symptoms resulting from lactose maldigestion are not a major impediment to the ingestion of a dairy-rich diet supplying approximately 1500 mg Ca/d.
Digestion and tolerance of lactose from yoghurt and different semi-solid fermented dairy products containing Lactobacillus acidophilus and bifidobacteria in lactose maldigesters--is bacterial lactase important?
TLDR
Despite the differences in the lactase and bacterial content, lactose was as well digested and tolerated from the three different semi-sold fermented dairy products.
