Abstract
Five nuts, namely almond, cashew nuts, peanuts, pine nuts and pistachio, commonly consumed in Pakistan, were analyzed for their inorganic element contents. Instrumental neutron activation analysis (INAA) methodology, using different irradiation, cooling and counting protocols, was adopted to determine Al, Br, Ca, Cl, Co, Cs, Eu, Fe, Hg, K, La, Mg, Mn, Mo, Na, Rb, Sc, Se, Sr and Zn. The investigated nuts were found to contain substantial amounts of Ca, Cl, Fe, Mg, K, Na and Zn. Dietary intake of the essential inorganic elements present in these nuts, as compared to the recommended dietary allowance, has also been calculated. This has further substantiated the nutrient role of nuts in the prevention of cardiovascular disease, as in addition to their established efficacy in improving the lipid profile, they are a rich source of cardioprotective trace elements such as magnesium, zinc, iron and calcium. Toxic elements were present in very low concentrations in nuts.
