Abstract

Insights

A pro-inflammatory diet, measured by the dietary inflammatory index (DII), is linked to an increased risk of developing multiple sclerosis (MS). Higher DII scores indicate a greater risk for MS development.

Area of Science:

  • Nutrition Science
  • Epidemiology
  • Neurology

Background:

  • Diet and inflammation are recognized as potential risk factors for multiple sclerosis (MS).
  • Understanding the relationship between dietary patterns and MS risk is crucial for public health.
  • Previous research suggests a link, but further investigation is warranted.

Purpose of the Study:

  • To evaluate the predictive ability of the dietary inflammatory index (DII) for multiple sclerosis (MS) risk.
  • To investigate the association between a pro-inflammatory diet and MS in a case-control study.
  • To provide evidence on dietary factors influencing MS susceptibility.

Main Methods:

  • A case-control study was conducted in Iran with 68 MS cases and 140 controls.
  • Dietary intake was assessed using a validated food frequency questionnaire to compute the DII.
  • Logistic regression models, adjusted for various covariates, were employed to analyze the data.

Main Results:

  • Individuals with higher DII scores (indicating a more pro-inflammatory diet) exhibited a significantly increased risk of MS.
  • The DII showed a positive association with MS risk when analyzed as both a continuous and categorical variable.
  • A 1-unit increase in DII corresponded to an approximate 15% increase in MS risk.

Conclusions:

  • A pro-inflammatory diet is associated with an elevated risk of developing multiple sclerosis.
  • Dietary modification may play a role in MS prevention strategies.
  • Further research can explore specific dietary components contributing to MS risk.
