Lipid composition of some commonly consumed traditional Nigerian dishes.

BACKGROUND: Lipids in the diet have been associated with the rising prevalence of many chronic diseases. The present study aimed to provide information on total lipid, free fatty acids, triacylglycerol and cholesterol contents of some dishes consumed in northern, southern, western parts of Nigeria, as well as dishes generally consumed in all parts of Nigeria. This would result in a resource that would be used by nutritionists and dietitians in meal planning. METHODS: The present study is analytical in nature. The composite dishes included a blend of cereals, roots and tubers, legumes, fat and oil and vegetables and were analysed for total lipid, free fatty acids, triacylglycerol and cholesterol contents spectrophotometrically. RESULTS: Burabisko (a millet based dish) had the lowest free fatty acid (0.1 mg per 100 g) and cholesterol (1. 9 mg per 100 g) contents, yam with eggs (7.1 mg per 100 g) and miyan-kuka with semovita (415.9 mg per 100 g) contained the highest amounts of free fatty acid and cholesterol, respectively. The total lipid and triacylglycerol content were lowest in gbegiri with eko (2.6 g per 100 g) and 3.1 mg per 100 g respectively. Stewed beans with fried plantain, however, had the highest total lipid (86.5 g per 100 g) content and yam with eggs had the highest triacylglycerol (122.5 mg per 100 g) contents. The moisture content of the dishes ranged between 59.68 and 81.73% in melon seed with vegetable soup and burabisko, respectively. CONCLUSIONS: For the first time, we have provided the lipid profile of standardised traditional dishes consumed in Nigeria. These dishes contribute a significant proportion of lipids to the diet of Nigerians, which are essential for assessing the nutrient intake of Nigerians.

Activity pattern, energy intake and obesity among Nigerian urban market women.

Activity pattern, energy intake and body mass index (BMI) were studied in a group of 232 women aged 19-65 years. The subjects were selected from five major markets in Abeokuta Township using a systematic random sampling technique. With the aid of a structured questionnaire and 24-h diet recall, information was collected on socio-demographic characteristics and the food and nutrient intake of the subjects. Information on the activity pattern was collected by recall and random spot observation methods. The result indicated that the majority (61%) of the respondents spent a total of 16 h on both domestic and market activities. An average of 11.5 h was spent in the market on predominantly sedentary activities. The mean energy intake of the women was 3701 kcal (15.4 MJ), which constituted about 164% of the recommended dietary allowance. Roots and tubers, cereals and legume form the major source of nutrients; while fried foods featured prominently in the menu. Eighty-nine women (38.4%) have a BMI within the healthy range of 18.5-25, while a total of 136, representing 58.6%, have a BMI greater than 25. A total of 66 women, representing 48.5% of the 136 women whose BMI was above 25, have a BMI in excess of 30 and are classified as obese. Both the energy intake and activity pattern of the respondents correlated positively with the BMI. This study has established a high risk of obesity among urban market women in Nigeria.
