Background
“Eat eggs and exercise to live longer! ”
Obviously, this ‘headline’ is fictitious, but it got your attention, didn't it? Reports of new research findings in the area of food and
health seem to get a lot of media coverage, after all, food and health issues are of interest to nearly everyone. Reporters,
academics, and health professionals all want the latest information —as do consumers. A single study and the reports surrounding
it can send many people in search of the latest food or supplement holding the promise of good health.
Frustrated and confused by the tremendous amount of food and health information reported nowadays , many people want
simple certainties to help them protect their health through diet. The trouble is that single studies rarely provide such certainty,
although they often get big headlines.
The media, health professionals, and educators are the gatekeepers of today's food and health information. They have a large
influence on what consumers hear, read, and believe about food and health. Along with that comes the responsibility to provide
the facts accurately, put them in perspective, and help people understand how the findings may affect their behaviour and health
choices. Responsible media reporting means that new studies should be critically reviewed before being publicised. News releases
and study abstracts, although helpful for the identification of interesting research, do not provide all the information necessary to
accurately report findings to the public.
Fortunately the process of critically reviewing scientific research becomes easier and faster with practice. This EUFIC Review is
designed to help the media, health professionals, and educators understand how to read and evaluate food and health related
scientific studies. It presents an overview of key information to look for, questions to ask, and other important considerations.
A Process of Discovery and Debate
To consumers, it often seems that contradictory studies about food and health appear in the media almost weekly, leaving many
to wonder why researchers can't get it right the first time. The answer is not straight forward, because to understand it means we
must accept uncertainty.
The scientific process is a road of discovery. It is the process of gaining knowledge about the universe through the observation of
measurable evidence. Contrary to what many people believe, this ‘road’ is not a straight, smooth motorway: researchers may
take different directions of exploration, going down routes that twist, turn, and sometimes even backtrack or come to a dead end,
before the facts are uncovered. Even then, the facts uncovered may be only part of a larger, partially understood phenomenon,
which requires further research before we come to more complete answers.
As a result, the scientific process—how studies are designed, conducted, and reported —frequently generates a great deal of
debate. Tracking the debate is often key to putting new research into context. With that in mind, new research studies published
in scientific journals should be viewed as discussions among scientists. In these discussions, almost no one gets to have the final
word, as it is rare that a study provides a final, complete answer. In fact, occasionally even old, accepted research results are
revisited and discussed again. With the benefit of new information or technology, scientists sometimes see previous research
results in a new light. The publication of research findings allows researchers to get opinions and critiques on their work by other
experts, which not only confirms or contradicts their conclusions but also adds to the body of literature on a subject and so helps
shape future research.
The bottom line is that dialogues characterised by cycles of revision, conjecture, assertion, and contradiction are frequently key to
investigating a subject. Although such cycles often frustrate non scientists and contribute to increasing public scepticism about
advice on food and health, it is important to understand that science is evolutionary, not revolutionary. Because scientific research
explores the unknown, uncertainty is an unavoidable part of current investigations. Only through repeated research and analyses can certainties emerge.
