Mediterranean diet and childhood asthma

Abstract

The adoption of a traditional Mediterranean diet could contribute significantly to the improvement of patients diagnosed with childhood asthma.

Effects of Fruit and Vegetable Consumption on Risk of Asthma, Wheezing and Immune Responses: A Systematic Review and Meta-Analysis

“…Cross-sectional design was most commonly used (Table 1) with 8 case-control studies (Table 2), 13 cohort studies (Table 3) and 7 clinical trials (Table 4). The majority of studies were conducted in UK ( n = 8) [1,18,22,23,24,25,26,27], but also in Australia ( n = 5) [28,29,30,31,32], Greece ( n = 5) [13,33,34,35,36], Spain ( n = 4) [37,38,39,40], Italy ( n = 4) [9,41,42,43], Brazil ( n = 3) [44,45,46], Netherlands ( n = 3) [21,47,48], USA ( n = 3) [9,49,50], Canada ( n = 2) [20,51], Finland ( n = 2) [52,53], India ( n = 2) [54,55], Japan ( n = 2) [56,57], Mexico ( n = 2) [19,58] Sweden ( n = 2) [17,59], Taiwan [60,61] ( n = 2), Albania [62], China [63], Colombia [64], Germany [7], Ireland [65], Norway [66], Portugal [67…”

“…Forty-one studies including nine cohort [21,33,37,41,47,48,53,56,65], six case-control [19,20,44,45,49,68], 22 cross-sectional studies [1,7,9,13,17,26,27,34,35,36,39,40,43,46,50,51,54,61,63,64,66,70], and four experimental trials [24,25,38,60] assessed the effects of fruit and vegetable intake on asthma or asthma-related symptoms in children and adolescents. An inverse association of fruit and vegetable intake and asthma or wheeze was reported in 22 studies [1,9,13,19,21,26,33,35,38,39,41,43,45,49,50,54,60,63,65,66,70,71], while seven studies […”

“…An inverse association of fruit and vegetable intake and asthma or wheeze was reported in 22 studies [1,9,13,19,21,26,33,35,38,39,41,43,45,49,50,54,60,63,65,66,70,71], while seven studies [7,24,27,34,36,53,56] did not observe any significant association. Twelve studies [17,20,37,40,44,46,47,48,51,61,64,68] found mixed results.…”

“…The study reported 18% lower FeNO levels in Groups 2 (adding banana) and 3 (adding banana + apple) following the intervention. In a study by Calatayud et al [38], 104 children aged 1–5 years with current asthma participated in a nutritional education programme based on the traditional Mediterranean diet for one year. The authors reported that fruit and vegetable intake increased significantly with a concomitant decrease in inhaled glucocorticoids use.…”

Does adherence to the Mediterranean dietary pattern reduce asthma symptoms in children? A systematic review of observational studies

“…Of the remaining forty-nine potential studies, thirty-four full texts were considered inappropriate based on the exclusion criteria (not study population, n 6; not intervention, n 12; not study type, n 11; no abstract or full text available, n 5), leaving a total of fifteen studies relevant to the topic. Specifically, eleven cross-sectional, one intervention (with no control group), one casecontrol and two cohort studies investigating the association between children's adherence to a Mediterranean dietary pattern and asthma (17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31) .…”
