How many have you had today? It is 10am and I am on my second. I will have a third before the day is out, possibly a fourth. I can feel good about every one I consume, to a point, research says. You know what I am talking about: coffee.

A host of experts agree that drinking coffee comes with benefits. American longevity researcher Dan Buettner, who coined the term “Blue Zones” for places with longer life expectancies and lower rates of chronic disease, calls coffee one of the greatest longevity beverages there is.
Why is that? Well, moderate coffee intake – up to three to four cups a day – is linked to longer telomeres.

Telomeres are “caps” at the ends of our chromosomes – a bit like the plastic tips of shoelaces to stop the fabric fraying. Telomeres naturally shorten with age, but the process appears to happen faster in people with major psychiatric conditions.

This seems to be linked to chronic psychological stress, inflammation, oxidative stress and hormonal dysregulation, in which the body is always, or often, under pressure.

We have known for some time that coffee drinking is good for us – now research suggests that moderate intake might help slow cellular ageing even in people with mental health disorders and fast-shrinking telomeres.
