Coffee is a drink enjoyed by millions. And the latest research suggests that it might provide a range of health benefits.

These benefits are varied and likely stem from the vitamins and minerals within the bean itself. During brewing, these nutrients seep into the dark liquid.

Let’s dig into the research and look at the potential health benefits of coffee. 

1. Improves microbiome diversity  

Your gut microbiome contains trillions of microorganisms. And having a diverse gut microbiome is associated with good health. 

ZOE’s PREDICT studies found that coffee drinkers tended to have more diversity in their microbiomes. One possible explanation has to do with the soluble fiber and prebiotic properties in coffee that feed beneficial gut bugs. 

In a ZOE Science & Nutrition podcast on coffee, Prof. Tim Spector, ZOE’s scientific co-founder and an expert on the gut microbiome, explained:

“It’s probably the drink you have regularly that contains the most fiber. There’s more fiber in it than a glass of orange juice.”

There’s a long list of ways to improve your gut health, and it seems that coffee might be on that list. 

2. Improves cognitive function 

Some research suggests that coffee may be good for long-term cognitive health, including better memory and improved attention. However, other scientists haven’t found this benefit. 

Coffee may also slow cognitive decline and lower your chances of developing Alzheimer’s disease.

Interestingly, caffeine alone may not be responsible. Studies in mice show that other compounds in coffee may contribute to these effects.

A study comparing decaffeinated and caffeinated coffee didn’t find any cognitive benefits linked to decaffeinated coffee.

Still, a wide range of factors influence brain health, and scientists need to carry out much more research to understand the precise links between coffee and thinking ability.

3. Reduces the risk of gallstone diseases

Drinking coffee may reduce your risk of developing gallstones later in life.

A recent study determined that drinking at least 6 cups a day was associated with a 23% reduced risk of developing symptomatic gallstone disease, compared with drinking no coffee.

But if you currently have gallstones, you may want to avoid coffee, due to the stimulating effect it has on the gallbladder.
