Lactose: Evolutionary Role, Health Effects, and Applications

Lactose is more than the sugar in milk: it sits at the intersection of mammalian evolution, human digestion, nutrition, gut microbiology, and food manufacturing. This specialist reference brings those connected subjects into one volume, offering readers a way to follow lactose from its biological origins to its roles in the body and in commercial products.

Edited by Marcel Paques and Cordula Lindner, the book draws on six chapters to examine lactose from scientific and applied perspectives. Its scope makes it useful for readers who want a grounded overview of the molecule rather than a discussion limited to diet or dairy alone.

From lactase persistence to human physiology

The opening chapters trace the evolution of lactose digestion and explore what happens as lactose is digested, absorbed, or metabolized. They address lactase persistence, the enzyme lactase, lactose’s physiological effects, and its significance in early nutrition and development.

Understanding intolerance and the gut microbiome

A separate discussion considers lactose intolerance and related food sensitivities, including symptoms, diagnosis, and management. The book also examines undigested lactose and microbial fermentation in the gut, weighing the complexity of possible effects rather than treating tolerance as a simple one-factor question.

Where lactose meets industry

The final chapters turn to practical applications: lactose as an ingredient in pharmaceutical formulations and its role in dairy production. These sections connect the molecule’s properties to its functions in products and manufacturing, complementing the earlier biological and nutritional material.

A cross-disciplinary reference for lactose research

With its coverage of evolutionary biology, nutrition, food science, and pharmaceutical uses, this reference is suited to food and dairy scientists, nutrition professionals, researchers, health practitioners, and graduate students. It offers a broad framework for exploring how one milk carbohydrate connects fundamental biology with questions of health and application.
