n recent years, there has been a growing interest in Health-Related Quality of Life(HRQoL) (1), defined as an individual’s or a group’s perceived physical and mental healthover time (2). HRQoL is frequently assessed alongside medical and psychological outcomesin many clinical settings and public health services, across a wide spectrum of diseases(3) and is considered an important dimension to measure during the development of newtreatments (4,5).Since the Ancient Greek era, the impact of nutrition on health has been widely reported(6,7), yet there remains a lack of knowledge about the link between nutrition and HRQoL(8). Our Research Topic, entitled “Nutrition and health-related quality of life: is it an ignoredoutcome? Volume II,” aimed to attract research from diverse backgrounds focusing on bothhuman nutrition and HRQoL. We were particularly interested in work that may clarifythe link between human nutrition and HRQoL, and the nature of their interaction. Wereceived five submissions; two were rejected and three original research papers were acceptedfollowing peer review. The submissions are international, from America and Europe.In the first study, conducted in America,Han et al.considered grip strength as a validindicator of HRQoL in a study with 2,127 participants of both genders aged 60 years andabove (9). They evaluated the association between dietary magnesium intake and handgripstrength, and whether this association was influenced by serum vitamin D status. They foundthat low magnesium intake was associated with reduced handgrip strength in participantswith a deficient serum concentration of 25(OH)D. They concluded that there is a needto increase magnesium intake in people with this deficiency in order to maintain suitablemuscle strength and good HRQoL.In the second study, conducted in Spain,de Lourdes Moreno et al.validated a Spanishlanguage version of the Coeliac Disease Questionnaire (CDQ). This simple instrument iswidely used to assess HRQoL in patients with coeliac disease (10) and this work will enablebetter assessment of HRQoL in the Spanish population.FrontiersinNutrition01frontiersin.org
