ABSTRACT An objective of the Food Stamp Program, recognized in its originating legislation, is to increase the nutrient intake of the poor. Economic theory suggests this might be achieved through income effects and program-related effects. This paper, using data from the Food Stamp Cashout Project, tests the effectiveness of food stamps and direct cash transfers in achieving this goal for a sample of elderly households. Food Stamp Program effects were negligible, and nutrient intake did not increase with income in either program. Controlling for the endogeneity of participation with a selection bias technique did not affect these results. [ABSTRACT FROM AUTHOR]

We investigated the effect of age on indices of vitamin B-6 metabolism in 36 fasting males aged 25-35, 45-55, and 65-75 y who ingested 17. 15 µmol vitamin B-6. There were no significant differences among groups in dietary vitamin B-6 intake, base-line erythrocyte pyridoxal 5'-phosphate (PLP), and total vitamin B-6 concentrations, and 24-h and baseline urinary excretion of total vitamin B-6 and 4-pyridoxic acid (4-PA). Base-line plasma PLP and total vitamin B-6 were higher (p < 0.05) in the youngest group. Increased serum alkaline phosphatase (AP) and decreased dietary vitamin B-6 intake were correlated with decreased base-line plasma PLP and total vitamin B-6. Changes in plasma and erythrocyte PLP concentrations and excretion of 4-PA and total vitamin B-6 postboad were not different among groups. Indices of vitamin B-6 absorption, phosphorybation, and excretion were not affected by age. [ABSTRACT FROM AUTHOR]

Abstract: Aging is associated with a host of biological changes that contribute to a progressive decline in cognitive and physical function, ultimately leading to a loss of independence, and increased risk of mortality. To date, prolonged caloric restriction (i.e., a reduction in caloric intake without malnutrition) is the only non-genetic intervention that has consistently been found to extend both mean and maximal life span across a variety of species. Most individuals have difficulty sustaining prolonged caloric restriction, which has led to a search for alternative approaches that can produce similar to benefits as caloric restriction. A growing body of evidence indicates that fasting periods and intermittent fasting regimens in particular can trigger similar biological pathways as caloric restriction. For this reason, there is increasing scientific interest in further exploring the biological and metabolic effects of intermittent fasting periods, as well as whether long-term compliance may be improved by this type of dietary approach. This special will highlight the latest scientific findings related to the effects of both caloric restriction and intermittent fasting across various species including yeast, fruit flies, worms, rodents, primates, and humans. A specific emphasis is placed on translational research with findings from basic bench to bedside reviewed and practical clinical implications discussed. [Copyright &y& Elsevier]

David Weinkove is an associate professor at Durham University, UK, studying host–microbe interactions in the model organism Caenorhabditis elegans. David has been focusing on the way microbes affect the physiology of their hosts, including the process of aging. In this interview, he discusses the questions shaping his research, how they evolved over the years, and his guiding principles for leading a lab. [ABSTRACT FROM AUTHOR]

Focuses on the growing concerns regarding the eating habits of the younger generations. Tendency of younger generations to consume fast food and the lack of nutritional value in such food.

The article features the interest shown by some elderly persons in exploring arts in the U.S. It revealed that there are thousands of elderly persons in the country that engaged in pursuing similar set behaviors and routines. If given the chance to examine art technique, they would pursue their exploration in the said field. Because of sensory loss and physical deterioration, such attributes limit their access to the community. It is recommended that if authorities provide an extension program to elderly person, they should consider nutrition site feeding centers, nursing and convalescent centers and special housing areas for the elderly as sites for educational and recreational arts offering. It should also be structured in a way that is suitable to them.

Presents a guidelines for putting oral health into the context of health eating for older people from the committee on Medical Aspects of Food Policy. General and dental advice; Skills training; Emphasis on the relationship between oral health and nutrition.

An introduction is presented which discusses aim and scope of the periodical regarding effects of nutrition and dietary components on aging and age-related diseases.

The article provides information on the visualization of neurochemistry and neural circuitry of reward in younger and older adults through neuroimaging. It mentions that age effects on reward were related to the food intake and economic decisions. It also states that anticipation of reward is more relevant than then delivery of reward. Furthermore, sex differences in reward mechanisms of older individuals is another effect of aging.
