IntroductionDiet in people with multiple sclerosis (pcMS) is of interest due to its potential benefit. The objective is to evaluate the changes in eating habits in pcEM, their opinion, sources of information, perception of effect and quality of current diet.MethodsCross-sectional observational study based on an online survey. The pcEM were convened by a patient association (ALCEM). Demographic, disease, and dietary change data were collected. Diet quality was assessed with the modified Cardiovascular Diet Questionnaire-2 (CDQ-2).ResultsTwo hundred and eight pcEM, 82% women, age: 41.5 (± 10.9), 47% reported changes in diet, of these 52% maintained an omnivorous diet (vs. 85% p>0.01), 14% gluten-free, 9% ketogenic/low carbohydrate, 5% lacto-ovo vegetarian, 4% pescetarian. The percentage of overweight was lower, and the quality of the diet was better (more fruits and vegetables, less saturated fat, more unsaturated fat) among those who modified their diet compared to those who did not (CDQ-2: 10.2(7.6) vs. 3.9(6.5) p<0.01), including in those who remained omnivores (CDQ-2: 8.1(6.7) vs. 4.1(6.1) p<0. 01). The 83% maintained the change, with 92% perceiving positive results. Main source of information: Doctor or nutritionist: 39%. There was discordance between the information received from the treating neurologists and their own opinion and expectations.DiscussionThe pcEM made changes in their eating habits, resulting in healthy eating, although only 40% had their doctor or nutritionist as an informant. More studies on the topic and a multidisciplinary approach are necessary.
