  With Artisan coffee shops popping up everywhere, kitted out with caffeine alternatives that’ll help you replace your mid-morning pick me up, it’s easy to assume coffee is bad for your health.  But it’s time to stop panicking - research now shows drinking 3 cups of coffee per day could be good for you.  

Coffee health benefits

The research, carried out by the University of Southampton across 200 studies, found those who drank three cups of coffee a day had less chance of suffering with heart problems.1 One of the most prevalent improvements was in the risk of liver disease. It’s worth bearing in mind – though - that age, activity level and whether participants were smokers could have played a part in the outcome of the study.

Coffee and diabetes

The benefits of coffee don’t stop at heart health. One study found coffee consumption to be linked with a lesser risk of developing type 2 diabetes, especially in women.2 The research found drinking coffee increased the amount of the protein ‘sex hormone-binding globulin (SHBG), which controls the sex hormones testosterone and oestrogen that are crucial in the development in the development of type 2 diabetes. Participants who increased their coffee intake by an average of 1.69 cups a day over four years ended up with an 11% lower risk compared with those who didn’t.

How much caffeine is in my drink?

  • One mug of filter coffee: 140mg
  • One mug of instant coffee: 100mg
  • One mug of tea: 75mg
  • One can of cola: 40mg One 250ml can of energy drink: up to 80mg
  • Bar of plain chocolate: less than 25mg
  • Bar of milk chocolate: less than 10mg

But is there other bad stuff in my coffee?

Some coffee varieties are extremely high in calories so, if your daily habit includes a frothy caramel latte, the health benefits of the coffee are probably outweighed by its significant calories. A caramel frappuccino contains more calories than a portion of lasagne.

Researchers at the University of Southampton advise drinking healthy coffees, as opposed to those containing extras like cream and sugar.

As far as everyday coffee drinkers go – you can sleep soundly knowing a few cups of coffee daily is less a bad habit, more a healthy one.

Caffeine risks

The NHS recommends pregnant women have no more than 200mg of caffeine a day as research shows the potential for miscarriage with more than 2 cups of instant coffee increases.

It’s also important to avoid disrupting your sleep pattern with too much caffeine. We suggest limiting your coffee consumption to the morning or early afternoon – so your body has plenty of time to flush out the caffeine in time for bed.
