Healthy Adolescent Diet Linked to Reduced Risk of Late-Onset Multiple Sclerosis

The study, published in the journal BMC Neurology by researchers from Tehran University of Medical Sciences, highlights the potential benefits of following Mediterranean dietary principles, which advocate for increased intake of plant-based foods, dairy, and fish.

Participants who consumed the most dairy products as teenagers saw a dramatic decrease in their odds of receiving an MS diagnosis compared to those with lower dairy intake. Other food categories, including seafood, fruits, vegetables, and nuts, were also linked to lower risks of late-onset MS.

Late-onset MS affects fewer than 10% of patients and tends to develop after age 50, often resulting in more severe disability and faster disease progression. The researchers emphasized the urgent need to recognize dietary influences as potential prevention strategies for those at risk of the disease.

The study involved 83 late-onset MS patients and 207 controls without neurological diseases, using a food questionnaire to gather information on dietary habits from ages 13 to 19. Results indicated that those with the highest dairy consumption had up to 79% lower odds of developing MS. Consuming more seafood, fruits, and vegetables also suggested protective effects against the disease.

While the findings are promising, the researchers acknowledged limitations, including potential recall bias from participants who might not accurately remember their past eating habits. Moreover, they called for further studies to validate these results and explore the mechanisms behind diet-related MS risk.

Overall, the study reinforces the idea that a health-conscious diet during adolescence may play a crucial role in preventing late-onset MS, advocating for increased awareness around nutritional choices as a preventive measure.
