Abstract
A sample set of 18 sweet potatoes [Ipomoea batatas (L.) Lam] segmented into six registered cultivars and 12 new varieties were evaluated. The 142 tuberous roots were obtained from a sweet potato germplasm bank (BAG-sweet potato; -27.417713768824555 and -49.64874168439556), specifically from plants belonging to a sweet potato breeding program. All samples were characterized according to their morphology, instrumental pulp color, proximate composition, and total dietary fiber. The analytical results were submitted to parametric and non-parametric statistical tests for sample variance data comparison. Moreover, the screening of the cultivars and new varieties was performed by exploratory statistical analysis, factor analysis (FA), and principal component analysis (PCA). From the sixteen independent variables that characterized the samples, the exploratory FA identified thirteen that had a communality greater than 0.7, with 92.08% of assertiveness. The PCA generated 4 principal components able to account for 84.01% of the explanatory variance. So, among the six registered cultivars, SCS372 Marina and SCS370 Luiza showed the capability to be employed as cultivars for production. Among the 12 sweet potato new varieties, samples 17025-13, 17125-10, and 17117 met the requirements for patent and registration. These results will be useful to farmers who wish to use these sweet potatoes in the development of their crops.

Abstract
Given the context that undernutrition in India co-exists with the problems of overweight/obesity and associated non-communicable diseases as well as micronutrient deficiencies, integrating nutritional concerns in developmental policies and governance is gaining significance. There are many schemes implemented to tackle malnutrition in India, but creating synergy and linking these schemes with each other to achieve a common goal are lacking. Nutrition communication can be an important component to create the synergy required to change malnourished India to malnutrition-free India. Although nutrition education/communication is recognized as a necessary component in various national nutrition programmes, there is not much evidence of distinct evaluation of these components. Only a minor proportion of community nutrition research has been devoted to nutrition education and communication. Although there are scattered efforts in experimenting with newer communication approaches and media for promoting nutrition, there is a dearth of published literature. In this review an attempt was made to critically examine the nutrition education and communication research and practice with special focus on India. This review provides a historical perspective of evolution of nutrition education and communication with an overview of communication approaches, media, methods and technologies used in various research studies and programmes as well as the lessons learnt.

Abstract
A life course perspective provides a framework for understanding how food choices develop in changing temporal, social, and historical contexts. This article describes the application of life course concepts to food choices, including trajectories, transitions, turning points, lives in place and time, and timing of events in lives. A life course approach to food choice can contribute to understanding the social and biological pathways of health risk and resilience over the life span. Life course analysis is a useful research and practice tool because of the many ways in which foods, the individuals choosing them, and food choice environments are changing.

Abstract
Since its release in 1992, the Food Guide Pyramid has become one of the most recognized nutrition education tools in US history. As such, it has been subject to criticism, particularly in several recent media reports that implicate it as the culprit in America's current obesity epidemic. What these reports often overlook, however, is that the diets of many Americans do not adhere to the dietary guidelines illustrated by the Pyramid, refuting the notion that the Pyramid is the cause of the nation's obesity problem. Data indicate that the more likely causes of escalating obesity rates are increased per capita caloric consumption and larger portion sizes, along with a lack of adequate physical activity. Although the Pyramid graphic was designed more than a decade ago, it still communicates three key concepts that continue to be the cornerstone of federal dietary guidance: variety, proportionality, and moderation. As such, it remains a viable and relevant nutrition education tool, especially when used by dietetics professionals as a component of individualized, comprehensive nutrition education and behavior modification interventions. As the United States Department of Agriculture begins to investigate whether the food intake patterns illustrated by the Pyramid are in need of updating, research is urgently needed to determine how nutrition education tools, including the Pyramid, can be most effectively implemented to help consumers adopt healthful eating behaviors and to improve the public health of America.

Abstract
Sequencing of the human genome has opened the door to the most exciting new era for nutritional science. It is now possible to study the underlying mechanisms for diet-health relationships, and in the near future dietary advice (and possibly tailored food products) for promoting optimal health could be provided on an individual basis, in relation to genotype and lifestyle. The role of food in human evolution is briefly reviewed, from palaeolithic times to modern-day hunter-gatherer societies. The aetiology of 'diseases of modern civilization', such as diabetes, heart disease and cancer, and the effect of changes in dietary patterns are discussed. The risk of disease is often associated with common single nucleotide polymorphisms, but the effect is dependent on dietary intake and nutritional status, and is often more apparent in intervention studies employing a metabolic challenge. To understand the link between diet and health, nutritional research must cover a broad range of areas, from molecular to whole body studies, and is an excellent example of integrative biology, requiring a systems biology approach. The annual cost to the National Health Service of diet-related diseases is estimated to be in excess of 15 billion, and although diet is a key component of any preventative strategy, it is not given the prominence it deserves. For example, less than 1% of the pound 1.6 billion budget for coronary heart disease is spent on prevention. The polygenic and multifactorial nature of chronic diseases requires substantial resources but the potential rewards, in terms of quality of life and economics, are enormous. It is timely therefore to consider investing in a long-term coordinated national programme for nutrition research, combining nutritional genomics with established approaches, to improve the health of individuals and of the nation.

Abstract
The Dietary Guidelines for Americans is the official nutrition policy statement for the United States. Government involvement in providing information on private behavior, such as food choice, is justified by the high cost of poor diets, as measured in medical expenses and lost productivity. The Guidelines are intended to provide an up-to-date, consistent information base for federal nutrition education and information efforts and food assistance program regulations. Through these policy mechanisms, the Guidelines are assumed to improve dietary behavior, and, ultimately, health. By law, the Dietary Guidelines for Americans must be updated every five years; however, there is no mandate for evaluation. Evaluation could provide useful information to assess the extent to which the Guidelines positively influence health and provide insights into reasons for their successes and limitations. However, evaluation would also present considerable challenges. This paper discusses the critical data and methodological needs for improving evaluation of the Dietary Guidelines for Americans.

Abstract
The authors assessed the accuracy of college students' use of the Food Guide Pyramid (FGP) in their diets and evaluated sources of error and nutritional adequacy of the pyramid. Students enrolled in an undergraduate nutrition class (N = 346) completed 3-day dietary records that were analyzed, using computer software, to determine individual recommended dietary allowance (RDA) values and the extent to which the students' diets met those values. The students' most common error in using the FGP was underestimating serving sizes. Only 8% of the students consumed the minimum recommended number of servings for all food groups, but diets that satisfied FGP recommendations also tended to satisfy RDA requirements. Less than 2% of the students who met the minimal number of FGP servings did not satisfy their RDA values, but less than 45% of the survey participants, regardless of gender or residence, met the recommended intake for dietary fiber. The FGP was judged to be a good indicator of dietary adequacy.
