Culture, Agriculture, Food and Environment, Volume 48, Issue 1, June 2026.ABSTRACT On the occasion of SAFN's 50th anniversary I reflect on the development of biocultural and human evolutionary approaches to human diet and nutrition. I maintain that SAFN and its predecessors the Committee (1974–1987) and then Council on Nutritional Anthropology (1987–2004) have modeled, fostered, and advanced biocultural work in anthropology ...

Neurogastroenterology &Motility, Volume 38, Issue 6, June 2026.Breath test–proven malabsorption does not reliably predict symptoms. Many patients without malabsorption still develop significant symptoms. Symptoms after lactose ingestion are linked to fructose sensitivity and functional GI disorders. Validated, test‐specific symptom assessment is required to identify patients who may benefit from treatment ...

Effect of lactase preparations in asymptomatic individuals with lactase deficiency : gastric digestion of lactose and breath hydrogen analysis [PDF]
, 2002 2002-05We compared two lactase preparations derived from Aspergillus orizae (AOL) and Penicillinase multicolor (PML) for stability in the stomach and overall enzymatic activity in 10 asymptomatic subjects with lactase deficiency.

American Journal of Human Biology, Volume 38, Issue 5, May 2026.ABSTRACT Lactose tolerance (lactase persistence) represents a very progressive human adaptation, the origins of which remain incompletely understood. This study aims to examine the geographical distribution of the two alleles associated with lactose tolerance in Eurasia (13910*T and 13915*G) in relation to the main Y haplogroups and autosomal ancestry ...

Lactase restriction and lactase persistence: a study of sri lankans and a paediatric population [PDF]
, 1990 Lactase is an enzyme, located on the small intestinal brush border, that hydrolyses the disaccharide lactose into its monosaccharides glucose and galactose, which are then absorbed.

BMC Genetics, 2009 Background Lactase non-persistence is a condition where lactase activity is decreased in the intestinal wall after weaning. In European derived populations a single nucleotide polymorphism (SNP) C/T-13910 residing 13.9 kb upstream from the lactase gene ...

Comparison of Quick Lactose Intolerance Test in duodenal biopsies of dyspeptic patients with single nucleotide polymorphism LCT-13910C>T associated with primary hypolactasia/lactase-persistence [PDF]
Acta Cirúrgica Brasileira, 2013 PURPOSE: To analyze the usefulness of Quick Lactose Intolerance Test in relation to the genetic test based on LCT-13910C>T genotypes, previously validated for clinical practice, for primary hypolactasia/lactase-persistence diagnosis.
