Roundtable on coffee and health concludes consumers often receive out-of-date advice

March 03, 2016

European consumer research1 conducted by the Institute for Scientific Information on Coffee (ISIC) to better understand beliefs, behaviours, and knowledge regarding coffee and a healthy diet, suggests consumers are confused about the potential health benefits of coffee, in part because the information they are receiving is not always in line with the latest science.

Moderate consumption of coffee at 3-5 cups per day has been associated with a range of desirable physiological effects such as improved alertness1 and a reduced risk of type 2 diabetes2,3, cardiovascular disease4,5 and cognitive decline6,7. It can be consumed as part of a healthy balanced lifestyle, providing fluid and small amounts of some nutrients, such as potassium, magnesium and niacin. Pregnant and breastfeeding women are also advised by EFSA that caffeine intakes of up to 200mg (2 cups of coffee) per day are considered safe for the foetus/infant8.

To further explore the consumer research findings, ISIC invited three eminent experts representing public health nutrition, preventive medicine, and consumer behaviour to review and discuss the latest scientific research on coffee and health, consumers' knowledge and attitudes, and the role of healthcare professionals in disseminating healthy diet advice.

Conclusions from the roundtable:
  • Many consumers are not aware of the potential health effects of coffee, with 49% believing it may cause health problems.
  • Consumers often obtain out-of-date information on coffee and health from the internet and media sources (such as magazines and TV) but also from healthcare professionals e.g. 56% of the survey respondents who believed that "drinking coffee increases the risk of heart disease" heard this either online, in a newspaper/magazine, or on TV and 16% heard this from a doctor, nurse, or dietician.
  • Consumers may not always distinguish between coffee and caffeine, viewing it purely as a stimulant, missing out on coffee's specific components and potential physiological benefits.
Key Recommendations
  • HCPs need up-to-date accurate, science-based information that healthcare professionals can discuss and share with their patients.
  • Informing patients about the latest science on coffee could result in behavioural change as consumers begin to appreciate its role within a healthy diet.
  • More education is needed to help the general public identify reliable/unreliable information from media/online sources.
The experts were:
  • Prof Chris Seal: Professor of Food and Human Nutrition, and Chair of Board of Studies, Food & Human Nutrition BSc at Newcastle University, UK.
  • Prof Lluís Serra-Majem: Director of the Research Institute of Biomedical and Health Sciences, Las Palmas de Gran Canaria University, Spain
  • Dr Agnès Giboreau: Research Director, Institut Paul Bocuse, France
Professor Lluís Serra-Majem commented: "We are increasingly seeing consumers obtain health information from the internet and media sources rather than from qualified healthcare professionals. We need to improve access to information for all parties, as in my experience healthcare professionals sometimes impart their own opinions to patients, even if this is only based on personal experience, not scientific fact."

Professor Chris Seal continued: "Whilst key dietary messages such as 'consume five portions of fruit and vegetables a day' and 'eat less fat, salt and sugar' are well known, many remain unaware of the potential health benefits of coffee. Helping people to understand how regular daily consumption of 3-5 cups of coffee might reduce their risk of certain diseases and long-term health conditions could prompt behaviour change."

Dr. Agnès Giboreau said: "Coffee is often drunk to accompany or conclude a meal therefore it's important that consumers understand the value of what they're drinking as well as eating. Personal habits, such as the way someone takes their coffee, are often based on experiences and cultural backgrounds, and so changing behaviour must be consistent with culture, beliefs and typical habits."

There was unanimous agreement amongst the expert panel that healthcare professionals, including dietitians, nutritionists and clinicians, are the best source of reliable, scientifically-grounded information on healthy lifestyles for consumers. They are also best placed to advise consumers on where to find reliable information on coffee and a healthy diet. Healthcare professionals could also encourage consumers to analyse the credibility and validity of health information they read or see in the media. It was agreed that this group of professionals should be supported with regularly-updated educational material to ensure that the advice they give is accurate.

About ISIC

The Institute for Scientific Information on Coffee (ISIC) is a not-for-profit organization, established in 1990 and devoted to the study and disclosure of science related to "coffee and health." Since 2003 ISIC also supports a pan-European education programme, working in partnership with national coffee associations in nine countries to convey current scientific knowledge on "coffee and health" to health care professionals. ISIC's activities are focused on:
  • the study of scientific matters related to "coffee and health"
  • the collection and evaluation of studies and scientific information about "coffee and health"
  • the support of independent scientific research on "coffee and health"
  • active dissemination of balanced "coffee and health" scientific evidence and knowledge to a broad range of stakeholders.
ISIC respects scientific research ethics in all its activities. ISIC's communications are based on sound science and rely on evidence and scientific studies derived from peer-reviewed scientific journals and other publications.

ISIC members are six of the major European coffee companies: illycaffè, Jacobs Douwe Egberts, Lavazza,Nestlé, Paulig, and Tchibo.
