In Kate Lloyd’s article, the benefits of kimchi and kefir are mentioned, as well as yoghurt (Is it true that … eating yoghurt can heal your gut?, 24 March). What about beer, and why is it always missing from these lists? Real ale contains live yeast, is readily available, and is clearly palatable to a large part of the population. In addition, we all know what happens to gut health if we consume too much from the bottom of the barrel, where the excess yeast makes the beer cloudy. Could Kate please investigate?

• In a recent holiday let, a bedroom window had been improperly sealed, allowing cold winds to enter. Fortunately, there were enough scatter cushions to fill the entire window space (Letters, 23 March).
