Drinking coffee in moderation is the best way to go.

Heart

Boiled coffee, such as Greek or Turkish, and plunger coffee, contains more cholesterol-raising oils than other types of coffee, so it is recommended that you avoid or limit consuming them. “These oils are removed through paper, so instant coffee, coffee made with an espresso machine, is fine,” says Beth Thomas, national food policy advisor at Australia’s The Heart Foundation.

High levels of caffeine raise blood pressure short-term, so if you have high blood pressure, speak to your GP about how much coffee you can drink. The Heart Foundation recommends limiting your coffee intake to less than five cups of instant, café-style or percolated coffee a day.

Teeth

Coffee, particularly black coffee, stands teeth externally and internally. “The simplest stains on the surface of teeth can be removed with polishing,” explains Dr Peter Alldritt from the Australian Dental Association. “Intrinsic staining is where teeth become yellow internally. This is worse in coffee drinkers and requires professional bleaching.” Minimise stains by having a glass of water after a coffee.

Breath

“When you drink coffee, your mouth becomes dehydrated. When your mouth is drier, bacteria and bits of food are not washed away and can cause bad breath,” says Dr Alldrift. So drink water after a coffee to flush away bacteria and food.

Body Clock

Don’t have a double espresso or any other strong coffee during the three hours before bedtime – it turns back to your body clock by an hour. Caffeine updates the rise in the hormone melatonin that makes us sleepy, explains Dr John O’Neill from the MRC Laboratory of Molecular Biology in the UK.
