Abstract:
This study aimed to compare two consumer-grade mail-in nutrition test kits, Flemi Check and VitaNote, in measuring protein intake and identifying protein deficiencies. A total of 18 subjects (10 male, 8 female) aged 19 to 36 years participated. Descriptive statistics revealed that most subjects consumed between 60 and 80 grams of protein per day, slightly below the recommended 80 grams. The Flemi Check test identified 15 subjects as protein-deficient, while the VitaNote test identified 11. A significant disparity in protein consumption measurements was found, with the Flemi Check consistently underestimating protein consumption compared to the VitaNote test for 16 out of the 18 subjects, with a mean difference of 17.11 grams. However, both kits showed good agreement in estimating the recommended daily protein intake, with only a 2-gram difference. Given the high precision of the VitaNote test, the Flemi Check may not be considered as a reliable tool for assessing protein intake.
