Nutrition in Clinical Practice Ebook

Chapter 12

Diet and Cancer
The link between diet and cancer, supported by in vitro, animal, and epidemiologic studies, is convincing. Decisive intervention trials are for the most part lacking, however, because of the protracted time course of carcinogenesis and a lack of reliable surrogate markers in most cases. An exception is studies in populations with well-defined nutrient deficiencies that increase the risk of specific cancers, where supplementation may dramatically reduce risk; the Linxian study in rural China is noteworthy (1,2). Most reviews of diet and cancer cite the work of Doll and Peto (3) and suggest that one-third or more of all cancer is related to nutritional factors and potentially preventable by nutritional means. Dietary factors may influence cancer initiation, promotion, and progression via direct effects on DNA, indirect effects on immune function (see Chapter 11), and overall vitality (see Chapter 45).
As is the case for atherogenesis, the process of carcinogenesis may be affected both favorably and unfavorably by micronutrients and macronutrients. Initiation is fostered by mutagenic exposures, including nutrient compounds, and forestalled by immunosurveillance, the robustness of which is influenced by dietary pattern. Cancer promotion and progression appear to be more meaningfully associated with macronutrient intake and overall health than specific nutrient compounds, although the aggregate influence of certain nutrient groups, such as antioxidants and essential fatty acids may be considerable. Procarcinogens in the diet include heterocyclic amines and polycyclic aromatic hydrocarbons that result from pyrolysis (i.e., charring); acrylamide formed when starchy foods are cooked at high temperature (4); nitrosamines used or produced in the curing of meats; naturally occurring contaminants, such as aflatoxin B-1; naturally occurring chemicals in plants; and chemicals added to the food supply as a result of agricultural practices and food handling. While all of potential importance, the net effect of carcinogenic compounds in foods is generally thought to be small relative to the effects of dietary pattern on general health, and its profound influence on cancer risk. This contention is highlighted by the presence of naturally occurring mutagens in many plant foods, yet a consistent and strong inverse association between the consumption of such foods and cancer risk. Also germane is the issue of chemical contamination of food; there is widespread concern that pesticide residues on produce, for example, may at times be carcinogenic (5). If so, voluminous data largely from observational trials suggest that the benefits of a generally nutritious diet clearly outweigh any harmful effects of such residues on otherwise healthful foods. Nonetheless, a potential benefit from choosing organic alternatives—particularly in certain food groups (6)—is worthy of both consideration and study.

The V*lv* anatomy, phisiology, and pathology Pdf Ebook


This is a much needed book for the patient with v*lv*v*g*n*l symptomatology
too often faces the prospect of an incomplete evaluation and misdirected therapies.
There are many reasons for this. Physicians with practice time constraints
magnified by an office full of waiting patients too often begin their physical
examination with the introduction of the v*g*n*l speculum, bypassing the
v*lv*. In addition, the record of diagnostic accuracy of v*g*n*l infections by
physicians shows a high error rate and inaccurate diagnoses lead to inappropriate
-->
therapeutic
interventions, which only prolong and sometimes intensify patient’s symptomatology.
Finally, to a large extent, the care of patients with v*lv*v*g*n*l problems
requires dermatologic insights that are too often lacking for many practitioners.
