Briefly describe how a person could use scientific principles to evaluate nutrition and health claims

Answer 1

Valid nutrition information derives from scientific research, which has the following characteristics: Scientists test their ideas by conducting properly designed scientific experiments. They report their methods and procedures in detail so that other scientists can verify the findings through replication; Scientists recognize the inadequacy of personal testimonials; Scientists who use animals in their research do not apply their findings directly to human beings; Scientists may use specific segments of the population in their research. When they do, they are careful not to generalize the findings to all people; Scientists report their findings in respected scientific journals. Their work must survive a screening review by their peers before it is accepted for publication. With each report from scientists, the field of nutrition changes a little—each finding contributes another piece to the whole body of knowledge.
