High caffeine consumption linked to hallucinations
Having a large waistline can almost double your risk of dying prematurely even if your body mass index is within the ‘normal’ range, according to a new study of over 350,000 people across Europe, published in the New England Journal of Medicine. The study provides strong evidence that storing excess fat around the waist poses

High caffeine consumption could be linked to a greater tendency to hallucinate, a new research study suggests.
People with a higher caffeine intake, from sources such as coffee, tea and caffeinated energy drinks, are more likely to report hallucinatory experiences such as hearing voices and seeing things that are not there, according to the Durham University study.
‘High caffeine users’ - those who consumed more than the equivalent of seven cups of instant coffee a day - were three times more likely to have heard a person’s voice when there was no one there compared with ‘low caffeine users’ who consumed less than the equivalent of one cup of instant coffee a day.
The researchers say the findings will contribute to the beginnings of a better understanding of the effect of nutrition on hallucinations. Changes in food and drink consumption, including caffeine intake, could place people in a better position to cope with hallucinations or possibly impact on how frequently they occur, say the scientists.
In the study, funded by the Economic and Social Research Council and the Medical Research Council, 200 students were asked about their typical intake of caffeine containing products, such as coffee, tea and energy drinks as well as chocolate bars and caffeine tablets. Their proneness to hallucinatory experiences, and their stress levels, were also assessed. Seeing things that were not there, hearing voices, and sensing the presence of dead people were amongst the experiences reported by some of the participants.
The researchers, whose paper is published in the academic journal Personality and Individual Differences , say their finding could be down to the fact that caffeine has been found to exacerbate the physiological effects of stress. When under stress, the body releases a stress hormone called cortisol. More of this stress hormone is released in response to stress when people have recently had caffeine. It is this extra boost of cortisol which may link caffeine intake with an increased tendency to hallucinate, say the scientists.
Lead author, Simon Jones, a PhD student at Durham University’s Psychology Department, said: “This is a first step towards looking at the wider factors associated with hallucinations. Previous research has highlighted a number of important factors, such as childhood trauma, which may lead to clinically relevant hallucinations. Many such factors are thought to be linked to hallucinations in part because of their impact on the body’s reaction to stress. Given the link between food and mood, and particularly between caffeine and the body’s response to stress, it seems sensible to examine what a nutritional perspective may add.”
Co-author Dr Charles Fernyhough, also from Durham University’s Psychology Department, noted “Our study shows an association between caffeine intake and hallucination-proneness in students. However, one interpretation may be that those students who were more prone to hallucinations used caffeine to help cope with their experiences. More work is needed to establish whether caffeine consumption, and nutrition in general, has an impact on those kinds of hallucination that cause distress.”
Mr Jones added: “Hallucinations are not necessarily a sign of mental illness. Most people will have had brief experiences of hearing voices when there is no one there, and around three per cent of people regularly hear such voices. Many of these people cope well with this and live normal lives. There are, however, a number of organisations, such as the Hearing Voices Network, who can offer support and advice to those distressed by these experiences.”
The latest research from Britain says drinking too much coffee can cause hallucinations. According to a study by researchers at Durham University people with a higher caffeine intake, from coffee, tea and caffeinated energy drinks, are more likely to experience hallucinatory experiences such as hearing voices and seeing things that are not there.

Midlife coffee drinking can decrease the risk of dementia/Alzheimer’s disease (AD) later in life. This conclusion is made in a Finnish Cardiovascular Risk Factors, Aging and Dementia (CAIDE) Study published in the January 2009 issue of the Journal of Alzheimer’s Disease (Volume 16:1). This study has been conducted at the University of Kuopio, Finland in

A new study published online in The FASEB Journal shows that the equivalent of one dose of caffeine (just two cups of coffee) ingested during pregnancy may be enough to affect fetal heart development and then reduce heart function over the entire lifespan of the child. In addition, the researchers also found that this relatively

With childhood obesity increasing, school administrators and public health officials are reducing availability of sugar-sweetened beverages (SSB) in schools. In a study published in the November/December 2008 issue of the Journal of Nutrition Education and Behavior, researchers found that reduction or elimination of SSB from school menus has little effect on total consumption by adolescents.

Over the past two decades, the number of adults consuming sugar-sweetened beverages such as soft drinks, fruit drinks and punches has increased dramatically, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health. Researchers examined changes over the past two decades in sugar-sweetened beverage consumption based on nationally representative
