Lead toxicity and nutritional deficiencies.
Under appropriate conditions, deficiencies of certain minerals and vitamins as well as high intakes of dietary fat increase the toxicity of a given dose of lead in experimental animals. The severity of lead poisoning can also be increased by the consumption of either deficient or excessive levels of protein. Mineral deficiencies appear to have some of the most profound effects on lead toxicity,...
متن کاملNutritional Factors and Susceptibility to Lead Toxicity
Although the quantities of lead (Pb) to which individuals are exposed vary widely, susceptibility of an individual to the effects of a specific level of exposure is another highly important factor in development of lead toxicity. For example, susceptibility to lead toxicity can be modified by several dietary factors. Low dietary intakes of calcium or iron (20% of recommended levels) substantial...
متن کاملNutritional Deficiencies; Diagnosis and Treatment
The isolation in recent years of many vitamins in pure form and clinical tests of them have resulted in notable advances in our knowledge of their usefulness in clinical medicine. Dr. Youmans has been one of the pioneers in the study of this particular subject, and therefore is well qualified to write on it. As is evident from the title, as well as the preface, the body of information here gath...
متن کاملNutritional Deficiencies and Phospholipid Metabolism
Phospholipids are important components of the cell membranes of all living species. They contribute to the physicochemical properties of the membrane and thus influence the conformation and function of membrane-bound proteins, such as receptors, ion channels, and transporters and also influence cell function by serving as precursors for prostaglandins and other signaling molecules and modulatin...
متن کاملNutritional Deficiencies, Diagnosis and Treatment
no doubt largely accounts for much of the present-day ' shot-gun' practice in vitamin therapy. We therefore welcome this book as presenting a clear and reasonable account of the essential food factors and their deficiencies. The vitamins necessarily occupy a large -portion of this book; it also includes chapters on proteins, iron, iodine and calcium deficiencies. The aetiology, pathogenesis, di...
