Quantification of fatty acid and mineral levels of selected seeds, nuts, and oils in Northern Ghana.

The purpose of this study was to identify locally available foods that can be utilized by Northern Ghanaians to improve child growth status. An assortment of seeds, nuts and oils were collected from a local market, packaged in plastic containers, and shipped to the US for all analyses. Fatty acids (FAs) were extracted and derivatized to FA methyl esters prior to quantification by GC/MS. ANOVA were conducted on FA concentrations and Tukey's post hoc test was used to compare FA content. Food grade oils, particularly palm oil and shea butter, contained higher saturated and monounsaturated FAs than seeds or nuts. Soybean, was significantly higher in the essential omega-3 FA alpha-linolenic acid (2.98 mg/g), whereas neri seed (68.4 mg/g) and fermented dawadawa (seed; 56.3 mg/g) had significantly higher amounts of total polyunsaturated FAs than all other foods. Iron levels in soybean (353 mg/kg), neri (282 mg/kg) and fermented dawadawa (165 mg/kg) were also the highest of all foods. Together, these foods may be useful for future intervention to curb stunting and iron-deficiency anemia.
