Contribution of fish in improving micronutrients content in complementary foods for children aged 6 to 23 months in Lindi Rural District
(Academic Journals, 2021) Masanja, Hope; Jumbe, Theresia; Pacific, Renatha
Lindi region has high stunting prevalence of about 35%, and one of the factors that cause stunting is inadequate intake of micronutrients for children under 2 years old. This study aimed at assessing contribution of fish in improving micronutrients, specifically vitamin A, zinc and iron contents in complementary foods for children aged 6 to 23 months old children in Lindi Rural District. A cross- sectional study was done; interviews were conducted on 212 caregivers with children aged 6 to 23 months at Mchinga Ward. Information collected includes demographic information and commonly consumed complementary foods for targeted children through the use of 24 h dietary recall. Also, laboratory analysis for zinc, iron, vitamin A contents and proximate composition were done for commonly consumed foods. About 89.2% of children were given fish-based complementary foods. On average, fish-based complementary foods had higher vitamin A concentrations (279 μg RE/100 g serving) compared to non-fish-based complementary foods (4 μg RE/100 g serving), but low in iron and zinc concentrations (0.66 and 0.067 mg/100 g serving, respectively) than non-fish-based complementary foods (0.74 and 0.074 mg/100 g serving respectively). Furthermore, fish-based complementary foods had higher proximate composition (except for % moisture content) compared to non-fish-based complementary foods.
Similarities in functional attributes and nutritional effects of magadi soda and bean debris-ash used in cooking African traditional dishes
(African Journal of Biotechnology, 2011) Mamiro, Peter; Nyagaya, Martha; Kimani, Paul; Mamiro, Delphina; Jumbe, Theresia; Macha, Joyce; Chove, Bernard
Magadi soda and bean debris-ash have been used as condiments for a long time by various ethnic groups in East and Central Africa in cooking traditional dishes. The aim of the study was to investigate whether magadi soda and bean debris-ash had similar effects and functional attributes when added to traditional dishes during cooking. Reason for the addition of the two condiments has not been revealed by researchers. Mineral content, in-vitro bioavailability studies and pH of non-ashed and ashed magadi soda and bean debris were evaluated. The results indicated that high concentrations of sodium ions (30.2%) and potassium ions (64.2%) were observed in magadi soda and bean debris-ash, respectively. In-vitro iron and zinc bioavailability decreased significantly with the addition of magadi soda and bean debris-ash in maize, beans and sorghum. Equally, the cooking time was significantly reduced. The mean pH for both magadi soda (9.66) and bean debris-ash (9.75) were not significantly different indicating that both aqueous solutions had alkaline properties. The similarity in properties especially in mineral profile, alkalinity, decreased cooking time and lowered mineral uptake by magadi soda and bean debris-ash explain similar functionality in foods they are added to during cooking. Despite the similarities observed, communities should be informed of the negative nutritional effects of these condiments so as to diversify their meal patterns accordingly.
