Lactose needs to be digested by the small intestinal enzyme lactase into its constituent monosaccharides, glucose and galactose, before transport across the epithelial cell membranes. Lactase activity is therefore essential for the development of young mammals, since their sole source of nourishment is their mother's milk. This chapter summarizes what is known about the genetics and evolution of the lactase persistence (LP) trait. Symptoms of lactose intolerance can arise after an individual…

Adaptation to Lactose in Lactase Non Persistent People: Effects on Intolerance and the Relationship between Dairy Food Consumption and Evalution of Diseases

The literature is reviewed to explore how the divide between humans that can or cannot digest lactose in adulthood affects lactose handling by lactase non persistent persons and how this could lead to colonic adaptation by the microbiome.

Analysis of the target group of lactose-free functional foods for product development

The aim of this research was to assess the consumer habits of lactose sensitive persons in case of lactose-free products and their other shopping aspects for development of new, dairy-based

Probiotics--compensation for lactase insufficiency.

Yogurt and other conventional starter cultures and probiotic bacteria in fermented and unfermented milk products improve lactose digestion and eliminate symptoms of intolerance in lactose

Management and treatment of lactose malabsorption.

The usefulness of exogenous beta-galactosidase, yogurt and probiotics for their bacterial lactase activity, pharmacological and non pharmacological strategies that can prolong contact time between enzyme and substrate delaying gastrointestinal transit time, and chronic lactose ingestion to enhance colonic adaptation are discussed.

The acceptability of milk and milk products in populations with a high prevalence of lactose intolerance.

A positive standard lactose test is not a reliable predictor of the ability of an individual to consume moderate amounts of milk and milk products without symptoms, and among individuals with incomplete lactose digestion, there is considerable variation in awareness of lactose intolerance and in the quantity of lactOSE that can be ingested without symptoms.

Lactase deficiency in Thailand: effect of prolonged lactose feeding.

The data suggest that lactase in mammals may be an adaptive enzyme and Tile failure of the postsuckling decline to occur in man would be consistent with this hypothesis because of the continued inclusion of milk and milk products in the duet after infancy.

Influence of Lactose on Faecal Microflora in Lactose Maldigestors

Results suggest that in subjects with verified lactose maldigestion, part of the lactose passes into the colon, inducing changes in the colonic microflora composition.

Assessment of lactose absorption by measurement of urinary galactose.

Clinical picture of hypolactasia and lactose intolerance.

It is shown that adult-type primary hypolactasia and selective lactose malabsorption represent a major problem in the everyday work of general practitioners, particularly in populations where hypolACTasia is common.

Adaptation of lactose maldigesters to continued milk intakes.

It is suggested that the majority of African-American young adults who claim intolerance to moderate amounts of milk can ultimately adapt and tolerate > or = 12 g lactose in milk with minimal or no discomfort if milk is ingested in gradually increasing amounts.

Lactose absorption in patients with ovarian cancer.

Assessment of the capacity to digest lactose by measuring breath hydrogen production after oral administration of lactose provides some support for a role for lactose ingestion and galactose cytotoxicity in the pathogenesis of ovarian cancer.

Colonic adaptation to daily lactose feeding in lactose maldigesters reduces lactose intolerance.

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.
