Comparative effect of two edible sea-food, P.palludosa and E.radiata on serum lipid profile and atherogenic indices in rats

Abstract

Background: Pomacea palludosa (apple snail) and clams (Ergeria radiate) are staple edible mollusks, rich in minerals, vitamins, proteins and omega-3-fatty acids (involved in the prevention of cardiovascular diseases).
Aim: The study was conducted to ascertain whether or not consumption of sea foods will predispose to dyslipidaemia.
Materials and Methods: Rats were fed on Basal, reference casein, P. palludosa and E. radiate and plain soup diets.
Results: Results revealed significant (p<0.05) decreases in serum total and LDL cholesterols in P. palludosa diet recipients, all the diets increased (p<0.05) HDL-c vs basal diet. P. palludosa diet also resulted in significant (p<0.05) lowering of cardiac risk ratio and atherogenic coefficient, while E. radiata diet reduced the atherogenic index of plasma.
Conclusion: In conclusion, E. radiate and P. palludosa diet would not predispose to atherogenesis since it favored the good cholesterol (HDL-c). Nevertheless, P. palludosa has desirable influence on serum lipids, and protects better against atherogenesis than E. radiata.

Key words: Diets, E. radiata, P. palludosa, lipid profile, atherogenic indices, rats.
