In a recent study published in The Journal of Applied Laboratory Medicine, researchers evaluated the performance of a compact diagnostic assay that can accurately and rapidly diagnose lactose ...

Many adults in the world are unable to digest lactose, the principle sugar in milk, and for the first time scientists have unravelled a genetic code that has proved that lactose-intolerance is the ...

The genetic change enabling adults to digest lactose developed as a second stage, centuries after cheese making originated among early farmers who were lactose intolerant as adults. DNA evidence ...

A group of scientists has concluded that ancient Europeans drank milk for millennia despite the digestive problems it may have caused, casting doubt on theories on how humans evolved to tolerate it.

Lactose intolerance (lactase non-persistence) is the inability to digest the sugar (lactose) present in dairy products and is caused by a decline in the epithelial production of lactase-phlorizin ...

The gene that enables East Asian adults to drink milk without getting side effects like stomach cramps was probably inherited from Neanderthals, thousands of years before humans started consuming ...

A curious and paradoxical intolerance for lactose across the South Asian subcontinent could help explain why the ability for adults to consume fresh milk from other animals developed in other ...

Suckling of infants is universal among mammals, which are after all named after the Latin mamma for teat. Early mammals, around 200 million years ago, presumably had a variety of milk-specific sugars.
