Dietary patterns in clinical subtypes of multiple sclerosis: an exploratory study.

Abstract: Backround: Multiple sclerosis is a neurodegenerative disorder with a wide range in disease course severity. Many factors seem to be implicated in multiple sclerosis disease course, and diet has been suggested to play a role. Because limited data is present in the literature it was investigated whether variations in dietary intake may be related to the severity of the disease course in multiple sclerosis. Methods: Using a food diary during 14 days, the dietary intake of 23 nutrients and vitamins was measured in patients with primary progressive (n = 21), secondary progressive (n = 32), and benign multiple sclerosis (n = 27) and compared to each other. The intake measured was also compared to the intake of the Dutch population and to the recommended daily allowance. Results: Compared to the other MS groups, the secondary progressive MS patients had a lower intake of magnesium, calcium and iron. The total group of MS patients had, compared to the Dutch population, a lower intake of folate, magnesium and copper and a lower energy intake. Compared to the daily recommended allowance, the MS patients had a lower than recommended intake of folic acid, magnesium, zinc and selenium. Conclusion: Magnesium, calcium and iron intake may possibly be related to MS disease progression, and should receive further attention. This is important because no effective neuroprotective treatment for MS patients is available.

An assessment of the relative validity of retrospective interviewing for measuring dietary intake

Abstract: Van Leeuwen, F. E., H. C. W. de Vet, R. B. Hayes, W. A. van Staveren (Dept. of Human Nutrition, Agricultural University, The Netherlands), C. E. West and J. G. A. J. Hautvast. An assessment of the relative validity of retrospective interviewing for measuring dietary intake. Am J Epidemiol 1983; 118: 752-8.The relative validity of a method for determining dietary Intake four years previously was assessed. In May 1981, 79 people (46 women and 33 men, aged 29-69 years) were interviewed by use of the dietary history method concerning dietary intake in 1977. These results were compared with those obtained in this same group by means of a seven-day record in February 1977. For daily intake of energy and selected nutrients, the differences in mean intake were generally below 10%, while for six examined food groups, larger differences in the median estimates were noted. The results provide evidence that retrospectively collected dietary data have some meaningfulness, although questions remain concerning whether the retrospective dietary history method is sufficiently valid for use in a particular epidemiologic study.

Aluminium in food and daily dietary intake estimate in Greece.

Abstract: Aluminium content of foods, as well as dietary aluminium intake of the Greek adult population, was determined using graphite furnace atomic absorption spectroscopy after microwave sample digestion and food consumption data. Al content ranged from 0.02 to 741.2 mg kg⁻¹, with spices, high-spice foods, cereal products, vegetables and pulses found to be high in Al. Differences in aluminium content were found between different food classes from Greece and those from some other countries. Aluminium intake of Greeks is 3.7 mg/day based on DAFNE Food Availability Databank, which uses data from the Household Budget Surveys. On the other hand, according to the per capita food consumption data collected by both national and international organisations, Al intake is 6.4 mg day⁻¹. Greek adult population has an Al intake lower than the Provisional Tolerable Weekly Intake of 7 mg kg⁻¹ body weight established by EFSA. Cereals and vegetables are the main Al contributors, providing 72.4% of daily intake.
