Food Forms of Tannia (Xanthosoma sagittifolium) and Consumption Patterns in Southeastern Nigeria

Historically, Taro (Colocasia esculenta) was the primary nutrient-dense traditional staple in southern Nigeria until the introduction of Tannia (Xanthosoma sagittifolium). Xanthosoma possesses characteristics enabling its utilization in diverse food forms comparable to, or exceeding, the versatility of Irish potato. Human dietary habits are fundamentally influenced by food availability, diversity, and safety, shaped by climate, soil, geography, and culture. Shifts in economic status, education, and industrialization further modify consumption trends. The oil boom era (1973-1982) in Nigeria precipitated urbanization and increased preference for exotic foods in the Southeast. However, current economic challenges, coupled with renewed recognition of tannia’s nutritional and medicinal benefits, are facilitating the re-emergence of its former significance in the local food culture.
