Bloating after dairy isn’t always random - for many people, it’s genetic. 🧬🥛
Around 65% of adults globally experience a natural decline in lactase production after childhood. This is called lactase non-persistence, and it simply means your body makes less of the enzyme needed to break down lactose.
When lactose isn’t fully digested, it reaches the colon and gets fermented by gut bacteria. The result? Gas, bloating, cramps or changes in bowel habits.
But lactose intolerance isn’t black and white. Many people can still tolerate certain forms of dairy, particularly fermented or aged options like Greek yoghurt, kefir, and aged cheeses, because they contain significantly less lactose.
→ Your genes influence how much lactase you produce 🧬
→ Your gut microbiome influences how well you tolerate what you eat 🦠
Understanding both helps you personalise, rather than unnecessarily eliminate.
In our latest article, we explain:
– What lactase non-persistence really means
– Why symptoms vary between individuals
– How genetics and gut health interact
– A full list of low lactose dairy products that are often better tolerated
