Fifty‐one male Nigerian students completed a questionnaire on their food‐habits in Aberdeen and Nigeria. Few changes to food‐habits were made during their stay in Aberdeen. Forty‐five of the subjects used a food‐diary to record their food‐intake, Portion‐weights from weighed intakes carried out by male Nigerian students were used to calculate nutrient‐intake. The results differed from those reported in studies on Caucasians. Intake of some vitamins was low. Fibre‐intake was a little lower than that reported for Africans by other researchers and the same as that reported for European students. The amount of energy supplied by carbohydrate, fat and saturated fat was in line with current recommendations for the United Kingdom.

“…The UK COMA (DH, ) took into account the appearance of clinical signs of riboflavin deficiency at intakes below 0.5–0.8 mg/day (Adamson et al., ; Burgess, ; Horwitt et al., ; Nicol, ; Horwitt et al., ; Bro‐Rasmussen, ; Bates, ). The UK COMA also took into account the sharp increase in urinary riboflavin excretion for intakes higher than 0.11 mg/MJ (0.44 mg/1,000 kcal) (FAO/WHO, ; DHSS, , ) and the riboflavin intakes in British adults (Gregory et al., ) i.e.…”

Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) derives dietary reference values (DRVs) for riboflavin. The Panel considers that the inflection point in the urinary riboflavin excretion curve in relation to riboflavin intake reflects body saturation and can be used as a biomarker of adequate riboflavin status. The Panel also considers that erythrocyte glutathione reductase activation coefficient is a useful biomarker, but has limitations. For adults, the Panel considers that average requirements (ARs) and population reference intakes (PRIs) can be determined from the weighted mean of riboflavin intake associated with the inflection point in the urinary riboflavin excretion curve reported in four intervention studies. PRIs are derived for adults and children assuming a coefficient of variation of 10%, in the absence of information on the variability in the requirement and to account for the potential effect of physical activity and the methylenetetrahydrofolate reductase 677TT genotype. For adults, the AR and PRI are set at 1.3 and 1.6 mg/day. For infants aged 7-11 months, an adequate intake of 0.4 mg/day is set by upward extrapolation from the riboflavin intake of exclusively breastfed infants aged 0-6 months. For children, ARs are derived by downward extrapolation from the adult AR, applying allometric scaling and growth factors and considering differences in reference body weight. For children of both sexes aged 1-17 years, ARs range between 0.5 and 1.4 mg/day, and PRIs between 0.6 and 1.6 mg/day. For pregnant or lactating women, additional requirements are considered, to account for fetal uptake and riboflavin accretion in the placenta during pregnancy or the losses through breast milk, and PRIs of 1.9 and 2.0 mg/day, respectively, are derived.

“…Although diseases of the skin have been studied in some African countries, 1,2 , 3,4 , 5,6 , 7,8 the provision of dermatology services is as yet a relatively underdeveloped aspect of medicine in sub‐Saharan Africa. This study was undertaken with a view to determining the pattern of skin diseases seen in a sub‐Saharan community and comparing it with that of a European one.…”
