Confused about what’s good for your skin?
Is honey good for your skin? Should you avoid essential oils when you are pregnant? What are parabens?
Confused on what is good for you and your skin? You love your new moisturizer or eye shadow. Then, hold on the next day a new study says its ingredients are BAD… Everyday there are reports and studies that contradict the study the day or week before. It’s hard to know what to believe! How do we figure out the information that is coming from all these different sources?
We are here to help!
Let’s look at an example of a study about protein.
In a popular magazine it states that The Scandinavian Journal of Medicine & Science in Sports says the timing of taking whey protein doesn’t matter for women over 60. They can take it before or after a workout.
Should we should believe it or not?
First off, how reliable is the study. There are three ways to measure reliability:
- Over time (test-retest reliability) meaning it has been tested and retested over a significant amount of time.
- Across items (internal consistency) meaning they tested a number of the same items.
- Different researchers (inter-rater reliability) meaning that different researchers got the same results.
- The use of a control group to verify results.
Another factor is validity in the study. According to www.linguistics.byu.edu › faculty › henrichsenl › ResearchMet. Validity in data collection means that your findings truly represent the phenomenon you are claiming to measure. For example you would not measure how fast your nails grow when your study is about face moisturizer.
Also, take a look at who conducted the research and did they have an interest in the outcome. For example did a coffee company fund the research study that confirmed coffee is good for us?
The question is how can you determine quickly if that the study about food, supplements or your skincare products are something you should be concerned about?
Well, if the study is from a source you never heard of and does not give you enough details about how they came to that outcome it may be questionable. Did they tell you how many people participated in the study? What was the timeline of the study, years or months? You may need to do your own research to find more studies to confirm this.
