Dietary pattern and risk of multiple sclerosis

Area of Science:

• Neurology
• Nutritional Science
• Epidemiology

Background:

• Nutrition is hypothesized to influence multiple sclerosis (MS) etiology.
• Specific dietary patterns linked to MS risk remain largely undefined.
• This study investigated dietary patterns in MS patients versus healthy controls.

Purpose of the Study:

• To identify and compare dietary patterns between women with relapsing/remitting MS (RRMS) and healthy controls.
• To determine the association between specific dietary patterns and the risk of developing MS.

Main Methods:

• Dietary intake assessed using a 168-item food frequency questionnaire in 75 RRMS patients and 75 controls.
• Factor analysis employed to define major dietary patterns.
• Multivariate logistic regression utilized to analyze the relationship between dietary patterns and MS risk.

Main Results:

• Traditional, lacto-vegetarian, and vegetarian dietary patterns were inversely associated with MS risk.
• High animal fat dietary pattern showed a positive association with increased MS prevalence.
• Specific food components within patterns influenced MS risk (e.g., inverse relation with low-fat dairy, red meat; positive relation with animal fats, potato).

Conclusions:

• Major dietary patterns demonstrably influence the risk of relapsing/remitting multiple sclerosis.
• Findings suggest potential for dietary modification in MS risk management.
• Further research into specific nutrient and food group impacts is warranted.
