Association between the Mediterranean Diet and Metabolic Syndrome with Serum Levels of miRNA in Morbid Obesity. Nutrients. 2021 Jan 29;13(2):436http://hdl.handle.net/10668/17155The Mediterranean diet (MD) could be involved in the regulation of different miRNAs related to metabolic syndrome (MS). We analyzed the serum level of mir-let7a-5p, mir-21, mir-590, mir-107 and mir-192 in patients with morbid obesity and its association with the MD and MS. There is an association between the adherence to MD and higher serum levels of mir-590. Mir-590 was lower in those patients who consumed >2 commercial pastries/week. Mir-let7a was lower in those who consumed ≥1 sweetened drinks, in those who consumed ≥3 pieces of fruit/day and in those who consumed less red than white meat. A lower mir-590 and mir-let7a, and a higher mir-192 level, were found in patients who met the high-density lipoprotein cholesterol (HDL) criterion of MS. A higher mir-192 was found in those patients who met the triglyceride criterion of MS and in those with type 2 diabetes (T2DM). There is an association between specific serum levels of miRNAs and the amount and kind of food intake related to MD. Mir-590 was positively associated with a healthy metabolic profile and type of diet, while mir-192 was positively associated with a worse metabolic profile. These associations could be suggestive of a possible modulation of these miRNAs by food.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Mediterranean dietMetabolic syndromemiRNAMorbid obesityType 2 diabetes mellitusCardiometabolic Risk FactorsDiabetes Mellitus, Type 2Diet SurveysDiet, MediterraneanEatingFemaleHumansIncidenceMaleMetabolic SyndromeMicroRNAsMiddle AgedObesity, MorbidPatient Complianceresearch article33572759open accessMicroARNsMetabolomaLipoproteínas HDLDieta mediterráneaDiabetes Mellitus tipo 2Síndrome metabólico10.3390/nu130204362072-6643PMC7911421https://www.mdpi.com/2072-6643/13/2/436/pdf?version=1612533860https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7911421/pdf
