ABSTRACT
This study explores the nutritional value of the flesh and visceral mass of two freshwater snail species, Pila africana and Lanistes libycus, commonly consumed by rural communities in Nigeria. A comprehensive analysis was conducted to evaluate their proximate composition (moisture, fat, crude protein, fiber, and ash), mineral content (sodium, potassium, calcium, magnesium, and iron), and vitamin composition (A, B, E, and K). Results revealed that P. africana had higher levels of moisture, fat, and minerals in both the flesh and visceral mass compared to L. libycus, which had a higher protein and carbohydrate content. The findings suggest that both species serve as vital sources of essential nutrients for human consumption, offering a low-fat alternative to traditional protein sources, and are beneficial for individuals with cardiovascular health concerns. The study underscores the importance of these snails in providing accessible nutrition to resource-limited communities.
