topicAvocado Lipid Profile Randomized Trial
claimThe HAT was a multicenter trial with 4 clinical centers and a coordinating center designed to evaluate the effect of consuming 1 avocado per day on visceral adiposity (primary endpoint) and other cardiometabolic risk factors (secondary endpoints) in 1008 participants [,].

claimPre-post intervention changes in metabolites, cardiometabolic risk factors (blood pressure, lipid profile, glucose, insulin, high-sensitivity C-reactive protein), visceral adipose tissue volume, and hepatic fat fraction were evaluated using Wilcoxon tests.

topicAvocado Lipid Profile Randomized Trial
claimConclusions Avocado intake was associated with subtle shifts in serum metabolites related to lipid, carbohydrate, and amino acid metabolism, with weak effects on visceral adipose tissue volume, plasma triglycerides, and total cholesterol concentrations.

topicAvocado Lipid Profile Randomized Trial
claimMethods Secondary analysis was conducted using untargeted metabolomics to assess fasting serum metabolite profiles at baseline (preintervention) and 6 months (postintervention) in a subset of participants with abdominal obesity from the HAT (Habitual Diet and Avocado Trial), who were randomized to the avocado group (n = 120; 70% women; 49 ± 13 years of age; body mass index 33.1 ± 5.7 kg/m 2 ).
