Objective To examine the effectiveness of green-Mediterranean (MED) diet, further restricted in red/processed meat, and enriched with green plants polyphenols on non-alcoholic fatty liver disease (NAFLD), reflected by intrahepatic fat (IHF) loss. Design For DIRECT-PLUS 18-month randomized clinical trial, we assigned 294 participants abdominal obesity/dyslipidaemia into healthy dietary guidelines (HDG), MED green-MED weight-loss diet groups, all accompanied physical activity. Both isocaloric groups consumed 28 g/day walnuts (+440 mg/day provided). The group tea (3–4 cups/day) Mankai (a Wolffia globosa aquatic plant strain; 100 frozen cubes) shake (+1240 total IHF% changes were quantified continuously proton magnetic resonance spectroscopy (MRS). Results Participants (age=51 years; 88% men; body mass index=31.3 kg/m 2 ; median IHF%=6.6%; mean=10.2%; 62% NAFLD) had 89.8% retention-rate, 78% eligible follow-up MRS. Overall, NAFLD prevalence declined to: 54.8% 47.9% 31.5% (green-MED), p=0.012 between groups. Despite similar moderate both achieved almost double loss (−38.9% proportionally), as compared (−19.6% proportionally; p=0.035 weight adjusted) HDG (−12.2% p<0.001). After 18 months, significantly higher plasma polyphenol levels versus HDG, detection Naringenin 2-5-dihydroxybenzoic-acid green-MED. Greater was independently associated increased intake, decreased meat consumption, improved serum folate adipokines/lipids biomarkers, microbiome composition (beta-diversity) specific bacteria (p<0.05 for all). Conclusion new suggested strategy amplified plant-based proteins/polyphenols Mankai, tea, walnuts, can IHF than other nutritional strategies reduce half. Trial registration number NCT03020186 .

Intestinal microbiota has its role as an important component of human physiology. It produces metabolites that module key functions to establish a symbiotic crosstalk with their host. Among them, short chain fatty acids (SCFAs), produced by intestinal bacteria during the fermentation partially and non-digestible polysaccharides, play roles in regulating colon physiology changing environment. Recent research found SCFAs not only influence signal transduction pathway gut, but they also reach tissues organs outside through circulation blood.
