Phosphorus is an essential element occurring in most foods. In typical Western diets, it is not harmful but does adversely affect tissues in the body when given in excess or paucity. This book provides a comprehensive review of various aspects of phosphorus in relation to human nutrition.

Phosphorus is an essential nutrient serving as a component of the cell membranes, the endocellular and external support components, cell energy cycles, and the molecules and enzymes that encode and regulate all genetic and synthetic information, as well as a multitude of other metabolic path- ways critical to all life forms—both plant and animal. Indeed, life cannot exist without a sustained source of phosphorus; yet in Western nations, we waste a great deal of this nonrenewable nutrient as it passes from farm to fork, through human and animal food consumption and ultimately excretion and loss to the environment. This book deals with three important features of the prevailing cycle of human phosphorus use that is emerging as potentially damaging to human and environmental health. In each of the 24 chapters, the expert contributing authors take a closer look at specific aspects of these features, which concern the serious life-threatening disease consequences of exces- sive phosphorus intake in vulnerable groups, the never-ending need to secure adequate phosphorus intake over all stages of life, and the negative and disruptive influence of human activities involving the use of phosphorus in food production. Many believe these activities have led to agricultural mis- management of the environment and unconstrained, widespread use of phosphorus in agricultural food production and the processing of food. Experts in a variety of scientific and medical fields have come together in this book to carefully examine how higher consumption levels of this essential nutrient, phosphorus, which are beyond an individual’s physiologic requirements, affect higher serum phosphorus concentrations shown to be significantly associated with a high incidence of morbidity and mortality in North America and Europe. Nephrologists and renal dietitians involved in the care of chronic kidney disease (CKD) patients have long been aware of the serious health risks associated with the body’s retention of dietary phosphorus as the decline in renal function progresses with the inability to restrict phos- phorus intake. Much of what is known about the damaging effects of elevated serum phosphorus and its link to bone, cardiovascular, and even the progression of kidney disease itself stems from studies focusing on dietary phosphorus intake in CKD. For a growing number of older individuals with failing kidneys—an estimated 26 million in America alone—total phosphorus intake must be delicately balanced between what the body needs for maintenance and the inability to efficiently excrete phosphorus. This is an increasingly difficult balance to maintain given the current high levels of phosphorus in processed foods and limited label information identifying the phosphorus content. The typical Western diet is high in natural sources of phosphorus such as red meat and added phosphorus in the form of inorganic phosphate salts whose use is widespread in industrial- ized countries to improve taste and other desirable qualities. Mounting evidence stresses the need for mandatory labeling of the phosphorus content of foods to assist in the management of renal dis- ease and the prevention of disease progression. What is an even more compelling reason to label the phosphorus content of foods concerns findings from recent large epidemiological studies suggest- ing significant associations between mild elevations of serum phosphorus within the normal range and cardiovascular disease risk and increased all-cause mortality in the general healthy population without evidence of impaired kidney function.
