Poultry linked to higher metabolic syndrome reversion in Tehran cohort; dairy and nuts show unexpected associations

Mar 8th 2026

A 7.6-year analysis of 576 Tehran Lipid and Glucose Study participants found that moderate poultry consumption was linked to greater likelihood of metabolic syndrome reversion, while moderate animal protein and higher dairy and nut intakes were linked to lower likelihoods of reversion, with results limited by a single baseline diet measure and possible residual confounding.

  • Study followed 576 Iranian adults with metabolic syndrome for a median 7.6 years and measured baseline diet with a 168-item FFQ.
  • Any-phase reversion occurred in 36.3% of participants, final-phase reversion in 15.5%, early reversion in 22.4%, and sustained reversion in 5.4%.
  • Moderate poultry intake (second tertile, 32–56 g/day) was associated with higher hazards of any-phase reversion (HR 1.47) and early reversion (HR 1.58).
  • Moderate animal protein intake (second tertile, 17–26 g/day) was associated with lower hazard of any-phase reversion (HR 0.68).
  • Higher dairy intake (≥530 g/day) and higher nut intake (≥6.9 g/day) were each associated with lower hazards of early reversion (dairy HR 0.52; nuts HR 0.57).
  • No significant associations were seen for total protein, plant protein, red or processed meat, or legumes, and sustained reversion analyses were underpowered due to only 31 events.
