Scientists said Wednesday that people who have three to four cups of coffee a day are more likely to have health benefits, experiencing lower risks of premature death and heart disease than those who don’t drink coffee.
Earlier studies have advised advantageous links between coffee drinking and liver disease. Research group has an interest in liver conditions. In the exact sense, we had formerly conducted two meta-analyses. One is looking for links between coffee drinking and cirrhosis and another at coffee drinking and cancer of the liver. Results found that there was a lower risk of both conditions who drank more coffee.
Discussing on the BMJ review, Eliseo Guallar, from the John Hopkins Bloomberg School of Public Health, said there was still no clear view about the results of higher levels of coffee intake.
“Moderate coffee consumption seems remarkably safe, and it can be incorporated as part of a healthy diet by most of the adult population.”- he added.
The University of Southampton researchers gathered information on the influence of coffee on all aspects of the human body, taking into account more than 200 studies - most of which were clear.
Umbrella analysis showed that drinking coffee is more often linked with benefits than harms. For some cases, the largest benefit cited to be linked with drinking three to four cups of coffee each day. This involved lower risk of death from any causes, or getting heart disease. Drinking coffee exceeding these amounts was not linked with harm, but the benefits were less taken into account.
Prof Paul Roderick, co-author of the study, from the faculty of medicine at University of Southampton, said the review could not be accepted if coffee intake had made the difference.
“Factors such as age, whether people smoked or not and how much exercise they took could all have had an effect. There is a balance of risks in life, and the benefits of moderate consumption of coffee seem to outweigh the risks,” he said.
The findings restore other recent reviews and studies of coffee drinking. So, overall, his message on coffee was encouraging.
The NHS suggests pregnant women have no more than 200mg of caffeine a day i.e. two mugs of instant coffee because over consumption can increase the risk of miscarriage. For other adults, moderate caffeine consumption is equal to 400mg or less per day - or three to four cups of coffee.
Tom Sanders, professor emeritus of nutrition and dietetics at King’s College London, said coffee consumers may be healthy people to start with - and that could suddenly change the findings.
“Coffee is known to cause headaches in some people and it also increases the urge to go to the toilet - some people chose not to drink coffee for these reasons.
“Patients with abnormal heart rhythms are often advised to drink de-caffeinated coffee. Caffeine also acutely increases blood pressure, albeit transiently. “
