Why you shouldn’t take nutrition science at face value

The never ending egg conundrum: is it good or is it bad for you? The findings of a research published in JAMA on the benefits of eggs in one’s diet, were quite alarming. Two large eggs a day could increase a risk of cardiovascular disease and death by 17 percent. This led to an interesting reflection in Undark on the value of nutrition science as a whole and it’s reliability.

Why it’s relevant. According to Undark, nutrition science is most often based on observational studies. These methods are essentially surveys and tend to be imprecise. for the author, the reason could be that people don’t often remember what they ate precisely, therefore the margin for error is quite big. As a result of that, Undark advises to simply be wary of the new healthy food trends, the evidence aren’t always there.
