To make an informed
nutritional opinion, you need to use your background in nutrition
science, applied nutrition, statistics, and research design.
If you want to learn more about what a particular herb is useful
for, donít just look it up in an herb encyclopedia.
GO TO THE SOURCE.
(Have you heard that before?)
The public is counting on you, the nutrition professional to make
a sound, informed opinion based on your expertise, not the opinion

To evaluate information,
do a literature search to find out what articles have been published
in peer-reviewed journals.
Then find those articles and read them carefully yourself, evaluating
according to guidelines found elsewhere in this tutorial.
Read the review articles, epidemiological studies, animal and human
studies, and clinical trials.
Find out if similar studies have been done yielding similar results.
Look at the number of subjects in the studies and if they are representative
of specific age, gender, or ethnic groups.
If insufficient information exists to draw a specific conclusion
or to make dietary recommendations, DONíT BE AFRAID TO SAY SO.
