The first consisted of information collection from 55 sellers on the CPO's sales conditions (containers, exhibition conditions and liquefaction method). The second and the last was to collect information respectively on the use and the consumption of dishes prepared with unbleached CPO respectively from 199 housewives and 309 individuals. The results reveal that 87% of sellers exposed CPO in the open air during commercialization although 44% of them knew that sunlight could have a negative impact on its quality. Heating and/or sun exposure were the technics used to liquefy oil. On the 98% of households that prepared with CPO, 93% of them often bleached it, although 64% were aware of the detrimental effect of this process. The social status of housewives significantly influenced this result. Unbleached CPO was used to prepare many dishes which were frequently consumed by 87% of people with a significant influence of lifestyle and region of origin. The results of this study showed that CPO could be used for fight against VAD in Cameroon if it is carefully commercialized and used in households and if people frequently consume dishes prepared with unbleached CPO.

Total ash content of clams and oysters were 2.87% and 2.92%, respectively. These value were significantly (p<0.05) higher than those of periwinkle (rough and smooth) and whelks. Percentage crude protein ranged from 12.01 - 18.84% with oyster and clams given significantly (p<0.05) higher values. Protein digestibility of the shellfish were 11.90, 8.62, 16.75, 16.64 and 13.88% for periwinkle rough, smooth, whelk, oyster and clam, respectively, with oyster and whelk showing significantly (p<0.05) higher value. A total of six essential minerals: Iron, calcium, magnesium, phosphorus, potassium, and sodium were determined. Potassium was significantly (p<0.05) higher in clam (1286.00 mg/100g) and low in periwinkle smooth (618.90 mg/100g). Whelk was significantly high in zinc and magnesium with values of 23.66 mg/100g and 721.60 mg/100g, respectively. Significantly (p<0.05) higher fraction of soluble Na (343.30mg/100g), K (1040.00 mg/100g), Fe (14.50 mg/100g) and Ca (185.60 mg/100g) were noticed in oyster, clam, periwinkle rough and periwinkle smooth, respectively. Whelk was significantly higher in soluble Zn (8.95 mg/100g) and Mg (718.00 mg/100g). Total calcium was found to be high in whelk (709.80 mg/100g) but only 58.80% was soluble after digestion with periwinkle rough recording the highest bioavailable calcium (84.30%).
Practical Applications : The knowledge of the mineral bioavailability, protein content and digestibility of some selected shellfish can give indication of the nutritional advantage of shellfish in fortifying carbohydrate based diets as a step towards alleviating the problem of protein energy malnutrition. Knowledge from this study presents shellfish as source of high quality protein with all the dietary essential amino acids and essential minerals necessary for maintenance and growth of the human body.
