If you missed our support group meeting this month, have no fear! Here is what you missed: With new diets, new recommendations, and new products on the market almost every day, it is important to your health and weight loss success to learn how you can tell what information is believable and what is simply just fiction (or just wanting your money). Follow these steps to determine what/who you can trust for nutrition information:
1) Find the source of the information. There are three sources of information: primary, secondary, and tertiary. A primary source of information is the actual document where the information you are seeking was originally written. For example, a paper written by a clinical researcher on the benefits of red wine intake on the prevention of cardiovascular disease, is a primary source. The people who wrote that document were the ones who followed a tightly-regulated scientific process to publish that information.
A secondary source of information is a source that summarizes/re-hashes the information that was originally presented in the primary source. For example, an article in a magazine could be written about a research study that was recently published. The article may even mention that the study was performed by researchers at Harvard. However, is this article believable? Not necessarily. The article can choose to leave out some really important information, such as how many people were involved in the study or whether the study was performed on humans or mice. Both of those pieces of information are necessary when it comes to whether a study/piece of information is believable. Therefore, always try to find the primary source that the article mentions and read it for yourself. Do not trust the reporter/writer to determine what information you do and do not need to know. A tertiary source of information is a compilation of primary and secondary sources. Once again, determine what the primary sources are and try to read them for yourself.
2) Determine if that source is credentialed in nutrition. Not all primary sources are believable. Trustworthy experts are educated and credentialed. Someone who was not trained in a science could claim that they have the credibility to publish material, but in reality, they do not. For nutrition information, believable professionals include:
- Registered Dietitian (RD): an individual who possesses at least a bachelor’s degree and some additional studies and experience in nutrition and dietetics. This person has also passed the Registration Exam for Dietitians.
- Licensed Nutritionist: depending on what state you live in, a Registered Dietitian could be called a Licensed Nutritionist. Generally, they are the same thing. However, the RD is a national title. Be sure this person has still maintained their RD status.
- Professional with a Master’s degree or Doctoral degree (M.S., M.A., or Ph.D.): Many people have taken the study of nutrition beyond the bachelor degree level, including many Registered Dietitians. However, be aware, anyone who is not a Registered Dietitian is legally not capable to provide clinical dietary counseling or treatment for individuals with illnesses or diseases. Be sure their Master’s or Doctoral degrees are in Nutrition/Dietetics. Just because someone has an MS or a PhD, does not mean they actually studied humans or know anything about nutrition and health!
- A Medical Doctor (M.D.) is trained to practice medicine in the U.S. This individual typically has limited training in the field of nutrition. Chances are a physician will refer you to a Registered Dietitian if you require a dietary plan to meet some specific needs you have.
- Professional Organizations of professionals with these credentials often publish secondary or tertiary materials to help the public. Examples of believable organizations include but are not limited to: The American Dietetic Association, The American Society for Nutrition, The Society for Nutrition Education, and The American College of Sports Medicine.
In summary, certain people have the training to publish believable primary sources of information. Make sure the information you are reading was written by one of these professionals!
3) Is it a Government Source? There are several federal and international agencies and departments that have come together to fund and publish very important and very large research studies on health and nutrition-related issues.
- The Centers for Disease Control (CDC) is often regarded as the leading federal agency that protects the health and safety of humans. The CDC is involved in health promotion, disease prevention and disease control. You can trust that nutrition-related materials published by the CDC were written by experts in that topic.
- The National Institutes of Health (NIH) is the world’s leading medical research center, which is a part of the Department of Health and Human Services (DHHS) and it aims to make scientific research on health and disease topics easily accessible and well-known in the public.
- The Food and Drug Administration and the United States Department of Agriculture are branches of the government that also aim to make disease prevention and related health information their top priority.
4) Is it selling something or is it too good to be true? Then take that information with a grain of salt. Instead, look up what some of the professional organizations or government sources listed above have to say on the topic. Or ask a Registered Dietitian!
Next time you cannot decide whether nutrition information is believable or not, ask for the source and analyze who that source is. Are the credentialed? Are they experts? Or do they just want your money?
