The evolution of lactase persistence [PDF]

Antropologia Portuguesa, 2012
Lactase persistence has long been recognized as a striking example of human dietary adaptation to changes in food production habits. The observation that the prevalence of lactase persistence is positively correlated with the cultural history of dairying

Ileal Lactase Expression Associates with Lactase Persistence Genotypes

Nutrients, 2021
(1) Background: Lactose digestion depends on persistence genotypes (including rs4988235), the frequency of which exhibits broad geographical variability. However, little is known about the relationship between lactase (LCT) genotypes and intestinal expression of LCT.

Lactase bacteria in intestinal mucosa are associated with diarrhea caused by high-fat and high-protein diet

BMC Microbiology, 2022
Background Excessive fat and protein in food can cause diarrhea by disturbing the intestinal microecology. Lactase is a functional enzyme strongly associated with diarrhea, while lactase bacteria in the intestine are an important source of microbial ...

Effect of lactase on symptoms and hydrogen breath levels in lactose intolerance: A crossover placebo‐controlled study

JGH Open, 2021
Background and Aim The absence of lactase in the intestinal villi due to mucosal injury or genetic factors causes undigested lactose to reach the colon where it is fermented.

Lactose intolerance: Causes, effects, diagnosis and symptom control [PDF]

, 2013
Lactose intolerance is a very common complaint which leads to a number of distressing gut symptoms in those affected. It can be quite easy to control by reducing milk consumption, and possibly by adding lactase to the diet. However, clinicians should be

Evolution of Lactase Persistence: Turbo-Charging Adaptation in Growth Under the Selective Pressure of Maternal Mortality?

Frontiers in Physiology, 2021
The emergence of the capacity to digest milk in some populations represents a landmark in human evolution, linking genetic change with a component of niche construction, namely dairying.

Comparative metabolomics in primates reveals the effects of diet and gene regulatory variation on metabolic divergence. [PDF]

, 2014
Human diets differ from those of non-human primates. Among few obvious differences, humans consume more meat than most non-human primates and regularly cook their food.

Fate of thymol and its monoglucosides in the gastrointestinal tract of piglets [PDF]

, 2020
The monoterpene thymol has been proposed as a valuable alternative to in-feed antibiotics in animal production. However, the effectiveness of the antimicrobial is comprised by its fast absorption in the upper gastrointestinal tract.
