Caffeine sits alongside red meat and stress as a key factor negatively impacting health, according to a groundbreaking study by the Australasian Research Institute (ARI) at Sydney Adventist Hospital.

For the past three years the ARI has been studying the effects of lifestyle on health. It confirmed the results of previous studies showing that stress, sleep (quantity and quality), red meat and body fat are key triggers for rises in oxidative stress. However, researchers were surprised to discover that caffeinated beverages were also significantly associated with oxidative stress in the body.

Oxidative stress is linked with accelerated ageing and the development of lifestyle diseases such as heart disease and certain types of dementia, including Alzheimer’s disease.

ARI CEO Dr. Ross Grant said the impact could be observed among research participants who drank as little as one cup of coffee a day.

“We didn’t just see an all-or-none effect,” he said. “We saw that if you had a little bit, it had an effect, if you had more, it had more of an effect, and so on.”

While he understands the social benefits of today’s café culture, he urged people to rethink their choice of drink.

“There are a lot of popular messages out there that caffeine is somehow good for you. It has been a sell,” he said.

“The arguments for the benefits of caffeine outside of the immediate social interaction are, I think, superficial and they trivialize the impact of what caffeine actually can and does do at a biochemical level.

“We have known for some time that caffeine is associated with heart disease, it reduces the quality of sleep, and increases anxiety and depression.
