The researchers and participants, therefore, there is a need

The study of Mhurchu
et al. (2017) presented
provided adequate study details and the evidence of strong design and analyses,
however was lacking in study implementation and in presenting sufficient generalizability
of findings, which negatively impacted its quality. The study therefore cannot
be considered neither clinically nor statistically significant. Since it relied on
convenience samples, the study could be improved by having supervised recruitment
increasing applicability to patients and wider
population. This
study was focused mostly on women and younger adults, limiting the
understanding of how food labels support food choices of men and later life. Food
label use may be crucial for older adults because of their higher risk of
diet-related chronic diseases. Future studies should focus on including a wider
population spectrum with respect to sex and age. Additionally, majority of
participant reported moderate knowledge about nutrition and such knowledge have
a positive impact on food label use and attitudes towards healthy food choices
and for that reason the study might to have reported significant difference between
groups. Following, the length of the study could be increased allowing possible
positive change in showing the difference in groups, thus improving statistical
significance. The technical issues with software were reported by researchers
and participants, therefore, there is a need for sensible steps to improve
its quality. One major issue caused by the technical problems was exclusion of
once randomized participants resulting in group size variance, however it could
have been minimised by application of multi
regression analysis. Future research need to determine which aspects of nutrition knowledge
are most critical to food label use and dietary decision making and investigate
whether increases in nutrition knowledge can promote significantly use of
nutrition information on variety of food labels.
