Quantitative Evidence of Benefit on Longevity from the Traditional Medicine Practice of Lifestyle Management Using Collected Data from Y2014 to Y2022 While Applying the Space-Domain Energy Model of Viscoplastic Medicine Theory Based On Gh-Method: Math-Physical Medicine

Since 2010, the author has practiced the lifestyle of choosing high-quality food from the Mediterranean diet which includes fresh vegetables & fruits, nuts & seeds, fish, and olive oil, while avoiding red meat, processed foods, unhealthy snacks, and sugary food. He also controlled his food portion size around 50% to 75% of his previous food consumption amount prior to Y2010 (as the 100% yardstick). He walks about 7 miles (10 km or 16,000 steps) each day, including 4,000 steps after each meal. In addition, he practices Chinese Tai-chi movement and arms/leg stretching. He maintains 7-8 hours of sleep with minimal interruption, such as nighttime urination. He avoids stressful events or incidents as much as possible and practices meditation but does not take herbs or receive acupuncture, spiritual therapies, etc.

Consumption of food in relation to income and saturation limit of Slovak households

Food represents everyday need and from this point of view is stable and computable demand on the consumer market. Based on the current development of households’ net money income and consumption expenditures, the aim of the paper is to point at the development of food consumption and changes in the cost of living of the population in Slovakia. Previous food consumption analyses proved that eating habits of the Slovak population comply neither with healthy lifestyle nor recommended doses, due to the low level of disposable net money income. In the analysis, linear and nonlinear functions were used in order to evaluate the development and saturation of demand for basic foods in Slovakia in the period 2008–2017. During these years, the share of expenditures on food and non-alcoholic beverages did not significantly change the consumption expenditures; they moved in intervals from 19.2% (2017) to 23.1% (2013), which is still a high share in comparison with EU countries (12.2%). The analysis provided in the paper is a suitable base for food businesses to create a product portfolio based on different net money income and saturation demand for basic foods.

Socioeconomic consequences of ciguatera poisoning in Rarotonga, southern Cook Islands

For the last 20 years, the world's highest incidence of ciguatera poisoning has been reported in Rarotonga, which is located in the southern Cook Islands. Therefore, Rarotonga is an ideal location to understand the socioeconomic consequences of ciguatera poisoning on small-island communities. In 2011, information on protein consumption preferences was collected from 179 Rarotongan households and compared with previous food consumption studies. This study showed that ciguatera poisoning halved the per-capita fresh fish consumption, from 149g/person/day in 1989 to 75g/person/day in 2006. Consequently, the consumption of alternative proteins, particularly imported meats, increased from 1989 to 2006. The cost-savings-and-avoidance valuation technique, used to estimate the direct loss in value of marketable goods and services, showed that the economic consequences of ciguatera poisoning amounted to approximately NZD $750,000 per year. Approximate costs associated with dietary shifts amounted to NZD $1 million per year. With the decline in cases of ciguatera poisoning in recent years, fresh fish has returned to the menu of residents, and the per-capita fresh fish consumption increased to 104g/person/day in 2011. Yet over the last two decades, the impact of ciguatera poisoning on the local Rarotongan community may have had long-term health-related consequences, and may have changed the social, cultural, and traditional characteristics of a once subsistence fishing lifestyle.

Food-related tolerance in capuchin monkeys (Cebus apella) varies with knowledge of the partner’s previous food-consumption

Capuchin monkeys, as well as several other primate species, show food-related tolerance in both captive and wild settings. Although researchers have revealed that past experience affects food-related tolerance, it is unclear if and how observing a partner’s previous food consumption affects tolerance. This question is important to determine the proximate mechanism of food-related tolerance, which may lead to food sharing, co-feeding, or tolerated taking. We investigated whether perception of another’s consumption of food affected the rate of tolerant food transfers among brown capuchin monkeys (Cebus apella). First, in the test condition, subjects observed their partner either eating (Eat-In View) or not eating food (No Eat-In View) through a window. In a control condition, the subjects could not observe the same partner behind an opaque screen, while the partner either ate (Eat-Out of View) or did not eat (No Eat-Out of View). After this, the subjects were provided with food to examine how well they tolerated their partner’s access to it through the mesh. Tolerant food transfers were sharply reduced after the subjects had observed their partner eat, but not in the control condition or after they had observed the partner not eating. We consider two possible hypotheses for this behavior, one relates to the internal state of the subject after having seen their partner eat (i.e., increased competitiveness, aggression, or food motivation). The other hypothesis relates to how the subject understands the partner’s motivational state after having witnessed food consumption, perhaps by grasping the partner’s need.

Analyzing Household Food Expenditure Patterns On Trips and Vacations: a Tobit Model

Based on the theory of consumer behavior, a tobit modeling procedure is applied to investi gate the relationship between vacation food expenditures and household sociodemo graphic characteristics. The resulting model identifies numerous determinants of spending variations of households, including earned and unearned income, education, occupation, number of children, age, marital status, ethnicity, employment status, and seasonality. The important and unique finding of the study is the decomposition of total effects on vacation food spending into current demand and potential market participation. This study also dif ferentiates itself from previous food consumption research in that it uses national survey data and examines travel-related food spending patterns of households on vacation trips. The implications of the results are discussed in the context of hospitality and tourism re search and marketing.

Retrospective versus Original Information on Diet: Implications for Epidemiological Studies

The aim of this study was to evaluate the use of retrospective information on diet in relation to the information originally reported. Hospital controls (n = 131) who participated in a case-control study on diet and pancreatic cancer in Stockholm, Sweden, answered a second postal questionnaire four years later about their current and previous food consumption. The food consumption was dichotomized for the purpose of the analysis. In relation to the original information, the use of retrospective information overestimated previous food consumption among subjects with increased intake, while retrospective information underestimated previous food consumption among subjects with decreased intake. These tendencies were slightly more pronounced in the age group 60-79 years than in the age group 40-59 years. For subjects with unchanged food consumption, there was a high agreement between original and retrospective information. Considerable differential misclassification could be introduced in an epidemiological study if cases and non-cases differ with regard to changes in food consumption.

Nutrition and aging: dietary intake of "apparently healthy" elderly (Dutch Nutrition Surveillance System).

The dietary intake (assessed through dietary history) of 539 apparently healthy, independently living elderly aged 65-79 years, was evaluated in a nationwide random sample. Except for pyridoxine, the intake of vitamins, minerals, and water was adequate according to the Dutch recommended dietary allowances. Fat intake (40 energy%) as well as P/S ratio (0.41) was assessed as being unfavorable, whereas the intake of vitamin B6 was marginal. The prevalence of obesity was higher among the women, while food selection was healthier as reflected in the higher nutrient density than among the men. Food consumption of elderly men (26%) and women (33%) on a dietary regimen was more prudent and nutrient density higher than among the elderly not on a diet. Our results are in accordance with previous food consumption studies among elderly in The Netherlands, but differ substantially from dietary intake figures for American elderly. Although the intake of energy and nutrients was lower among elderly men than among younger men, we conclude that age per se is not an important determinant of dietary intake among Dutch apparently healthy elderly aged 65-79 years.

Some recent findings in obesity.

The tendency of some obese subjects to an energy-sparing reaction can be induced temporarily by attempts of the patient to reduce his overweight by prolonged starvation. This regulatory reaction may be induced by regulatory especially thyroid mechanisms. In obesity of both sexes a tendency to anaerobic energy utilization in the muscle can be revealed and so a tendency to decrease energy utilization in general. The differences in insulinemia (IRI) displayed a prevalence of maternal obesity in the group with higher levels of basal and stimulated IRI values, which decline after changes in diet and body weight. This behavior of IRI levels and amount and composition of diet indicate a possible permissive role of previous food consumption habits.

Diazepam increases 5-hydroxyindole concentrations in rat brain and spinal cord

Diazepam elevates serotonin (5HT) and 5-hydroxyindoleacetic acid (5HIAA) concentrations in rat brain and spinal cord. The maximal effect occurs 1–2 hrs after drug injection and is dose related between 5–20 mg/kg (intraperitoneal). The action of diazepam on brain 5HT and 5HIAA concentrations is modified by previous food consumption: the ingestion of a diet that raises brain 5HT and 5HIAA one hour before drug injection enhances the diazepam-induced increase in brain indoles; consumption of a diet that lowers brain 5HT and 5HIAA partially blocks the elevation in brain indoles that follows diazepam injection.

Seasonal Feeding of Larvae of Ctenicera destructor and Hypolithus bicolor (Coleoptera: Elateridae) on Potatoes Placed in the Field at Weekly Intervals1

At Saskatoon, Saskatchewan, over 98% of the tunnels in potatoes, placed in the top 6 inches of soil for 1-week periods during the growing season, were caused by larvae of Ctenicera destructor (Brown) even though about 25% of the total population was Hypolithus bicolor Eschscholtz. Numbers of larvae of C. destructor decreased from early spring until late June or early July, mainly from mortality, and then increased with the appearance of newly hatched larvae. There was a further mortality of larvae from September to mid-October. The majority of larvae were in the top 6 inches of soil during the season, and not more than 5% were in the bottom 9- to 12-inch layer. Numbers of tunnels in the potatoes increased in general with rising soil temperatures in the spring, to a peak in early or mid-June. Alternate depressions and peaks followed, with peaks occurring in early or mid-July and early or mid-August, the last being the greatest. Tunneling then fell off to a low level by early or mid-September. Depressions in tunneling in mid-summer and after early fall were associated with low soil moisture and/or reduced temperatures, but the relationship between tunneling and concurrent soil temperature and moisture appeared to be different at different times of the season. It is suggested that previous food consumption and acclimation temperatures and moistures may influence this relationship, and that general molting of the larvae might bring about peaks and depressions of feeding at certain times. The possible importance of food plants in the fall to larval survival is discussed.
