摘要:

SummaryCalcium is the most abundant mineral in the body and has important structural and metabolic roles. In the average British diet, milk and other dairy products and fortified white bread provide the major supply. The average intake in the UK is well above the current recommended daily amount although the intakes of some school girls are quite low and may be a cause for concern. The amount of calcium which is absorbed and excreted is affected by a number of dietary and physiological factors. The plasma ionized calcium concentration is maintained by the concerted action of 3 hormones, parathyroid hormone, vitamin D and calcitonin. Dietary calcium has been implicated in the development of osteoporosis through failure to achieve an adequate peak base mass during early years or an increased rate of bone loss in later life. The first possibility has not yet been addressed and the second has not yet been resolved. Calcium requirements are difficult to determine confidently and further research on the relationship between calcium and the attainment of peak bone mass in early life and of the ability of individuals to adapt to different calcium intake is needed.

摘要:

SummaryThe perception of risk in food‐related issues is strongly influenced by the outrage associated with the severity of the hazard in question, and the perception of benefit is strongly influenced by the euphoria associated with the gain. To understand the perception of risk and benefit, it is just as important to understand the components of outrage and euphoria, as it is to be able to assess the hazard and gain accuratel

摘要:

SummaryThere is much evidence that nutrients can influence the outcome of studies of carcinogenesis in experimental animals. At present, much of the information is contradictory and of uncertain relevance to man. This is because different nutrients appear to affect different stages of the cancerous process and there may be many interactions between the nutrients, and between the nutrients and the cancer‐causing agents. It is unlikely that such agents will ever be entirely eliminated from the human diet but there is a real possibility that several classes of nutrients have a protective effec
