[null,null,null,"Sommario/riassunto","Since publication of the previous edition of this successful book, there have been many advances in the field of food science and metal analysis and these have been taken into account of in compiling this new edition. Data on metal levels in foods and diets have been updated with information gathered from recent international literature. More than 80% of the text has been completely rewritten and, as the addition of a new subtitle suggests, greater account is taken than in earlier editions of the importance of the nutritional properties of many of the metals that we consume.
