@3lfares My grandpa would force me to drink a liter of goat milk a day when i was a child and I wound up lactose intolerant just like my mother. Here is a more recent study (still old): https://t.co/DtrxdnCThG Lactose intolerance is genetic enough for 23andme tests to detect it.

What people are saying
The discussion reflects a balanced interest in the genetics of lactase persistence, with comments like 'nice review article' and personal stories about lactose intolerance. Words like 'encouraging reading' and references to studies suggest moderate engagement, while mentions of genetic testing indicate recognition of its significance.
Most posts acknowledge or relate to the research, with some sharing personal experiences or referencing genetic tests, indicating a general agreement on its relevance.
Posts show moderate interest, with some encouraging reading, sharing links to studies, or personal stories, but others display limited curiosity.
The discussion includes personal anecdotes, encouragement to study, and references to scientific articles, demonstrating a genuine but not deeply investigative engagement.
The conversations highlight awareness of genetic factors and practical implications, such as testing and personal history, suggesting a modest impact on understanding or awareness.
Abstract in brief
- Lactase enzyme, found in the small intestine, is essential for digesting lactose in milk and is highly active during infancy but generally declines after weaning in most mammals, including humans.
- Some humans experience lactase persistence, a genetically inherited trait allowing continued high lactase activity into adulthood, enabling lactose digestion; this trait is controlled by a genetic variation (polymorphism) near the lactase gene, especially common in Northern Europeans.
- A specific mutation, located upstream of the lactase gene in the MCM6 gene, has been identified as a factor in lactase persistence, but it does not account for all differences in lactase expression among individuals.
