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.

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.
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.
