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 ...

The good news: It doesn't mean you have to say goodbye to your favorite slice of pizza.

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 ...

Lactose intolerance is usually diagnosed based on symptoms, but a healthcare provider can also perform breath and blood testing. Breath tests are also available as over-the-counter home test kits.

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.
