Understanding science

Science is a process by which we learn about all the things in the universe. It is the process of gaining knowledge through the observation of measurable evidence. 

To people 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. 

Science is not a straight, smooth road. Researchers, in their quest to learn, may take different directions of exploration, going down routes that twist, turn and even 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.
