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 ...

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 ...

Humans were consuming milk in Europe 9000 years ago and its incorporation into their diet pre-dated the evolution of a genetic variant that facilitated digestion of lactose in adulthood, a study has ...

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 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.
