Food preparation methods approaches to scaling legume consumption in sub-Saharan Africa (SSA)

Including legumes in existing cuisines and recipes are needed as legumes provide nutrient-dense food and income for households and communities (Muoni et al., 2019). However, challenges that legume consumers face include long cooking time, low shelf life, and anti-nutritional properties which cause digestibility problems (De Jager, 2019a, Shitta et al., 2021, Snapp et al., 2018). Approaches for dealing with these challenges include soaking, boiling, and keeping legumes in an airtight container (De Jager, 2019a, Yegrem, 2021, Tan et al., 2020).

Legume-based foods are not given much attention, as legumes are regularly deemed inconvenient and have an adverse taste (Röös et al., 2022) so to change people’s perception towards negative legume consumption, food preparation method approaches are necessary.

The use of legumes as meat binders with redeveloped meat products has a better opportunity to increase the nutritional quality of the meat products (Pintado and Delgado-Pando, 2020). Processing legume products into more convenient as well as ready-to-eat snacks can improve utilization and dietary transition to having more meals that include legumes in the diet (Ojiewo et al., 2015).

Legume nutrition education workshops for communities on growing legumes up to the preparation of legumes including legume processing to lengthen shelf-life. Food preparation methods approaches can also include the use of energy-saving technology when cooking legumes to reduce barriers to consumption. Dietary change to a more legume-based diet has been proposed as one of the approaches to decreasing the climate impact of the global and regional food systems while improving human health.

My Research Project under LEG4DEV Project

The research project that I have been working on was sponsored and run under the LEG4DEV project at the Ryan Institute involved food preparation and food cultures in sub-Saharan Africa (SSA), how food preparation methods have evolved with changing diets as well as legume consumption and preparation with the different cuisines that are influenced by the diverse cultures in SSA.

SSA has rich food cultures that shape diets as well as influence food consumption patterns. The study found that food preparation methods in SSA are passed on from older generations to younger generation through word of mouth as well as demonstrations during cooking, written recipes were hardly used.

Diets in SSA are prepared using simple carbohydrate staple eaten with soups, relishes and sauces which are prepared from a range of foodstuffs including grain legumes. Most of the protein consumption is derived from these staple foods and grain legumes (Noort et al., 2022).

Legumes in SSA are used as a source of food, generating income, feeding livestock and in some very rare cases some legume varieties are used as medicine or fuel (Muoni et al., 2019, Akpalu et al., 2013, Snapp et al., 2018, Powell et al., 2004)

Legumes that are mostly produced and consumed in SSA include: cowpea (Vigna unguiculata), groundnut (Arachis hypogaea), Bambara groundnut (Vigna subterranea [L.] Verdc.), soybean (Glycine max), chickpea (Cicer arietinum), pigeon pea (Cajanus cajan) and African yam bean (Sphenostylis stenocarpa) (Stanton et al., 1966).

Legumes are usually consumed as a soup, relish, sauce, stew, or as a snack prepared in different ways (WFP, 2022, De Jager, 2019a).

Legume consumption in SSA is quite reasonable and people consume for many nutritional benefits as well as cultural reasons.
