Food-related problems

Besides structure elucidation for the browning polymer, Py-GC/MS studies were also done in connection with food related problems [10] such as the use of sugar-ammonia browning polymers as food colors. 

The above questions are difficult to answer without comprehensive and relevant information. Such information will almost invariably be multivariate in nature in order to comprehensively describe the complex underlying problems. Therefore, the need for advanced experimental planning and subsequent advanced data analysis is obvious. Chemometrics provides the necessary tools for digging into food-related problems. This book is a highly needed and relevant contribution to the food research area in this respect. The book provides an impressive, very detailed and illustrative tour deforce through the chemometric landscape. 

The scientific community is indebted to Alexey Yablokov and Lev Fedorov for carefully examining the pesticide impact on public health and the environment. Their studies add to our knowledge and their results suggest ways that public health and environmental pesticide related problems could be avoided. Given the food security needs of the rapidly expanding world human population, a safe and a productive agriculture are vital for the future. 

This chapter begins by discussing how consumer perceptions of risks associated with food additives compare to other food-related health risks. It then addresses the US government s system for monitoring adverse reactions from food additives. The bulk of the chapter focuses on additives that have been blamed for causing health problems and which have generated controversy in the US and other countries. Finally, there is a brief discussion of future trends and additional sources of information are provided. 

While both the fat-soluble and water-soluble vitamins had been found in a variety of foods, the problem of growth on milk diets had not yet been resolved, at least not in the minds of Osborne and Mendel. In a 1918 publication they said that they were impressed by the "apparent discrepancies in the quantitative relations of the amounts of milk required to furnish the vitamine factor in our experiments in contrast with those of Hopkins." (44) They went on to claim (and justly so) that a better understanding of the quantitative relations was highly desirable. "In view of the results of Hopkins experiments it has become generally believed that milk is one of the richest sources of the water-soluble vitamines among our food products." (45) The experimental results shown in this publication were certainly not in eccord with those of Hopkins in his 1912 paper.

Of particular importance is to keep in mind the in vivo nature of food-related studies, where it is expected the simultaneous activation of several biochemical pathways. For that reason, the selection and applicability of the different methods need to be understood. In addition, the source of the data may play a major role, in most cases the information is collected from different laboratories and the variability of the data might be due not only to the chemical structure but also to the different conditions under which the experiments were performed. As an example, problems arising from the collection of data in olfaction studies have been reviewed by Chastrette (1998).

Musculoskeletal disorders of the upper extremities (such as carpal tunnel syndrome and rotator cuff tendinitis) due to work factors are common and occur in nearly tdl sectors of our economy. More than 2 hUlion in workers compensation costs are spent annually on these work-related problems. Musculoskeletal disorders of the neck and upper extremities due to work factors affect employees in every type of workplace and include such diverse workers as food processors, automobile and electronics assemblers, carpenters, office data-entry workers, grocery store cashiers, and garment workers. The highest rates of these disorders occur in the industries with a substantial amount of repetitive, forceful work. Musculoskeletal disorders affect the soft tissues of the neck, shoulder, elbow, hand, wrist, and fingers. 

Robbins, a health advocate, runs through a litany of health-related problems involving not only his own family but also one of the founders of Ben Jerry s ice cream. (This sequence, like the many shots in the film of fast-food companies other than McDonald s, helps expand the argument beyond one company to look at larger issues of food choice and health.)...
