“Many people praise and acknowledge the healing power of plants, but few people actually take action to prevent their extension by planting and conserving them for future generations.” (Ernest Rukangira )

Digitaria exilis


Scientific name: Digitaria exilis

Family: Poaceae; Subfamily: Panicoideae; Genus: Digitaria

Vernacular names

Fonio, hungry rice, white fonio (En). Fonio, fonio blanc, petit mil (Fr).
Origin and geographic distribution. Fonio is only known from cultivation and its exact origin is unknown, but it is of ancient cultivation in West Africa. It may have derived from Digitaria longiflora (Retz.) Pers. in the inland delta region of the Niger.

Common names

Fonio, white fonio, hungry rice, hungry millet, hungry koos, fundi millet, petit mil, findo findi, acha, fonyo, fundenyo, afio, fini, fundi, ipoga, foundé, foni, pende, kpendo, founié,
pounié.

Main use and benefits

Historical records of the use of fonio as a cereal go back to the 14th century. Nowadays fonio is grown scattered from Cape Verde and Senegal to Lake Chad, especially on the Fouta Djallon Plateau in Guinea, the Bauchi Plateau in Nigeria and in north-western Benin. It is also grown in the Dominican Republic

Fonio is a highly palatable cereal that is drought tolerant. It is often consumed in West Africa before most crops are ready to harvest because it is one of the world’s fastest maturing cereals. It is believed to be one of the oldest cereals in West Africa, where it is indigenous. In some parts of Africa, like in regions of Mali, Burkina Faso, Guinea and Nigeria, it is a major part of the diet and in some places in Guinea it is even considered the staple.

Fonio is a fast maturing rate crop; this allows it to help humans during “hungry times” by being a very secure food. It is one of the most nutritious of all grains. It has medicinal properties as well; it is given to lactating women and diabetic people. Also, it does not contain any glutenin or gliadin proteins, which makes it suitable for people with
gluten intolerance.

Fonio is a cereal and can be made into porridge and couscous. It can be ground into flour and mixed with others to bake bread. It can be popped like popcorn and brewed in beer, or just eaten as the popped product. It is one of the best tasting cereals in the world and has been greatly preferred to common rice by some who have done comparisons of dishes made with each.

From Lake Chad to the savannah regions of Senegal and Guinea, fonio is an important food source for some 4 million people across West Africa. Fonio is one of the most nutritious of all grains. It is rich in important essential amino acids that are not found in wheat, rice, maize, or sorghum—such as methionine, leucine, valine and
cystine, which help synthesize protein. In gross nutritional composition, fonio differs little from wheat. The husked grain of white fonio has been shown to contain 8% protein, and in black fonio, 11.8% protein.

The difference lies in the amino acids it contains. In the white fonio analysis, for example, the protein contained 7.3% methionine plus cysteine. The amino acid profile compared to that of whole-egg protein showed that except for the low score of 46% for lysine, the other scores were high including 127% for leucine and 189% for methionine. It is also rich in iron, with 8.5 mg per serving, meeting at least half of the daily requirement.

Fonio is a staple food in various parts of West Africa, where it is also known as ‘acha’ or ‘fundi’, but it is also a prestige food (‘chief’s food’) and a gourmet item. In the Hausa regions of Nigeria, Benin, Togo and Ghana, special couscous types (‘wusu-wusu’) are prepared with fonio. In southern Togo, the Akposso and Akebou people prepare fonio with beans in a dish for special occasions.

Fonio grain is a valuable, easily digested feed for farm animals. The straw and chaff are excellent fodder and are often sold in markets for this purpose. Chopped fonio straw is mixed with clay to build walls of houses. The straw is also used as fuel for cooking or to produce ash for potash. Fonio grain is considered to have medicinal properties; it is recommended for lactating women and diabetic people.

Fonio (Digitaria exilis stapf.), an underutilized cereal, has the potential of providing enough food for the increasing population of people in West Africa and in the continent . Fonio contains about 7% crude protein that is high in leucine (9.8%), methionine (5.6%) and valine (5.8%) [6]. Among legumes, cowpea (Vigna unguiculata) is predominantly grown and consumed in Nigeria. It is observed that cowpea is economically and nutritionally important legume as major source of proteins in developing countries. In addition to amino acid profile and digestibility, the nutritional quality of cowpea and other legumes is compromised by the presence of anti-nutritional factors, mostly trypsin inhibitor .
Digitaria exilis also known as Acha is a tropical small-seeded cereal of great genetic developmental potential. It has several economic uses, long storage qualities, impressive nutritional and organoleptic qualities. The crop is faced with problems such as low yield, small grains that shatters and matures unevenly, hence, the crop is neglected and very little information is available on its improvement by mutagenesis.

Fonio is recognised for its superior nutritional properties among cereals, excelling in protein and micronutrient qualities. Fonio is also regarded as a grain with medicinal and healing properties, in line with the local integral view on nutrition and healthcare. In fact, fonio is considered the most digestive cereal of the West African drylands. It is also highly recommended for diabetic people, and often used in diets of sick people.

Fonio has also rich cultural values and significance among the dryland peoples of West Africa. For instance, it plays a central role in social events and celebrations. Fonio is largely recognised for its excellent culinary values. In fact, it is attracting some interest in elite gastronomic markets at national and international levels. In addition, fonio is regarded as a sacred crop among some rural peoples of West Africa, owing to its excellent agroecological capacities, its critical food security roles, its nutritional and healthcare properties, and its culinary uses.

Culture

Are there any specific taboos, specific cultural adaptations, historical perspective? Although it is referred to as ‘hungry rice’ in English, this is actually a term made by Europeans who misunderstood the original use for the crop. While it is good for those in hunger because of its growth rate, it was actually grown because the locals liked the taste, and it was reserved for royalty and special occasions. Some still use it in ancestor
worship and see it as a sacred crop. West Africans say “the best way to judge a woman’s stamina – essential in a good wife – is to watch her preparing fonio.” Preparing it is a painstaking task, which is why its cultivation is disappearing. Fortunately, a fonio husking machine was invented in the 1990s, which makes the process much easier.
