Objectives: The study was aimed to determine the nutritional status, serum proteins (total protein, albumin, prealbumin) and some anemia parameters (haemoglobin, iron, vitamin B12, homocysteine) of the Multiple Sclerosis (MS) patients. Methods: It was conducted on 63 MS patients (41 female, 22 male) who have applied to Ankara Numune Education and Research Hospital, Department of Neurology, Turkey. Some anthropometric and biochemical measurements were taken from the study group. Nutritional status was assessed by food frequency consumption results. Results: The Relapsing/Remitting Multiple Sclerosis (RRMS) was mostly seen in both genders (90.5%). The mean age was found 34.9±8.59 (20-56) years in the study group. The mean body mass index (BMI) was found as 25.2±4.86 kg/m 2 . While the mean albumin (p=0.021), prealbumin (p=0.005), homocystein (p=0.007), haemoglobin (p<0.001) levels were found to be significantly high; the vitamin B12 measurement (p=0.025) was low in males. The consumption of cheese, red meat, white bread, sugar and carbonated drinks decreased after the diagnosis period in females (p>0.05). There was no change in the consumption of egg, chicken, legumes, vegetable, fruit, margarine, butter and olive oil. Most of the two groups have consumed fish rarely before and after the diagnosis of MS. Conclusion: It was concluded that nutritional status of MS patients improved after diagnosis and serum proteins which also indicate that adequate and balanced nutrition were in desired levels.
