- Fatty acids and micronutrients are required for growth and development.
- The essential fatty acid content of local Ghanaian foods is poorly described.
- Local oils are generally low in essential fatty acids except for palm oil.
- Soybeans are a significant source of essential fatty acids and minerals.
- Agushie seeds/flour are significant sources of essential fatty acids and minerals.
Fatty acids (FA) and minerals play crucial roles in growth and development. However, Ghanaian diets consist mainly of starchy roots and cereals, with intake of fats and many minerals below recommended levels. The purpose of this study was to quantify FA and mineral levels of seeds, nuts, and oils in Ghana that are available but not usually incorporated in the diets. Seven seeds and five oils collected in Ghana were analyzed for FA and mineral composition by gas chromatography mass spectrometry (GC/MS) and inductively coupled plasma (ICP) emission spectroscopy, respectively. Soybean was found to contain high levels of alpha-linolenic acid (ALA) (3.77Â mg/g). Linoleic acid (LA) was higher in peanuts (65.8Â mg/g), agushie seeds (102Â mg/g) and agushie flour (122Â mg/g). Agushie seeds (88.4Â mg/g), agushie flour (111Â mg/g) and soybean (78.4Â mg/g) had appreciable levels of iron. In addition, both agushie seeds and flour contained high amounts of zinc. Taken together, these data indicate that several Ghanaian seeds, nuts, and oils are high in FA, including essential fatty acids, and minerals. Future studies should investigate increased incorporation of palm oil, soybeans, peanuts, cashew nuts, tigernuts, agushie seeds and/or flour into Ghanaian diets in areas where nutrient deficiencies are prevalent.
