APOA1 and metabolic syndrome: As previously remarked, ellagitannin-metabolizing phenotypes (urolithin metabotypes A, B, and 0) differ among individuals depending on their body mass index, and urolithin A in MetS patients only correlated inversely with glucose after intake of 30 g of nuts, while in healthy and overweight patients, urolithin A positively correlated with apolipoprotein A-I and HDL cholesterol after the intake of nuts [50].
