Background: Sustainable dietary practices can help reduce greenhouse gas emissions and promote planetary health. The importance of investigating how to promote sustainable dietary practices is therefore crucial. Nature Relatedness measures an individual's connection to nature and can predict environmental concern and stewardship.

Examining the Role of Nutrition in Cancer Survivorship and Female Fertility: A Narrative Review.

Female cancer survivors have a higher chance of experiencing infertility than females without a history of cancer diagnosis. This risk remains high despite advances in fertility treatments. There is a need to augment fertility treatments with cost-effective methods such as nutritional guidance to improve fertility chances.

Interactions with Nature, Good for the Mind and Body: A Narrative Review.

Interacting with nature may promote mental and physical health. There are multiple ways to interact with nature: indirectly, incidentally, and intentionally. How these types of interactions with nature may be associated with mental and physical health status and health behaviors is unclear.

Optimizing Fertility Treatment With Nutrition Guidance: Exploring Barriers and Facilitators to Healthful Nutrition Among Female Cancer Survivors With Fertility Challenges.

Introduction: Young women diagnosed with cancer are at an increased risk for infertility compared to women without a cancer diagnosis. Consuming a healthful diet comprised of whole grains, fruits, vegetables, and unsaturated fats has been found to improve both fertility and cancer survivorship. Given this reason, dietary interventions tailored to support female cancer survivors with fertility challenges are of immense importance.

The Implication of Physiological Ketosis on The Cognitive Brain: A Narrative Review.

Optimal cognitive functions are necessary for activities of daily living and self-independence. Cognitive abilities are acquired during early childhood as part of progressive neurodevelopmental milestones; unfortunately, regressive changes can occur as part of physiological aging, or more ominously, pathological diseases, such as Alzheimer's disease (AD). Cases of AD and its milder subset, mild cognitive impairment (MCI), are rising and would impose a burdensome impact beyond the individual level.

Interaction of Protein Preloads and Physical Activity on Intake of an Ultra-Processed, High Sugar/High Fat Food/Low Protein Food.

"Loss of control, LOC" eating is a major contributor to the development of obesity. Dietary protein is known to promote satiety, but little attention has been paid to the ability of protein, consumed in close proximity to snacking (20 min), to reduce the intake of ultra-processed, low-protein snack foods. We hypothesized that a high-protein preload (HP, 8 g of protein) consumed in close proximity to eating an ultra-processed snack food would reduce intake of the snack food as compared to a low-protein preload (LP, 1.

Altered prefrontal activation during the inhibition of eating responses in women with bulimia nervosa.

Background: The sense of 'loss of control' (LOC), or a feeling of being unable to stop eating or control what or how much one is eating, is the most salient aspect of binge eating. However, the neural alterations that may contribute to this experience and eating behavior remain poorly understood.

Methods: We used functional near-infrared spectroscopy (fNIRS) to measure activation in the prefrontal cortices of 23 women with bulimia nervosa (BN) and 23 healthy controls (HC) during two tasks: a novel go/no-go task requiring inhibition of eating responses, and a standard go/no-go task requiring inhibition of button-pressing responses.

Increasing Chocolate's Sugar Content Enhances Its Psychoactive Effects and Intake.

Chocolate elicits unique brain activity compared to other foods, activating similar brain regions and neurobiological substrates with potentially similar psychoactive effects as substances of abuse. We sought to determine the relationship between chocolate with varying combinations of its main constituents (sugar, cocoa, and fat) and its psychoactive effects. Participants consumed 5 g of a commercially available chocolate with increasing amounts of sugar (90% cocoa, 85% cocoa, 70% cocoa, and milk chocolates).

Can bone-regulating hormones and nutrients help characterize the metabolically healthy obese phenotype.

Background:: Bone-regulating hormones and nutrients play an important role in influencing metabolic health.

Aim:: The aim of this study was to determine whether bone-regulating hormones and nutrients, such as parathyroid hormone (PTH), 25-hydroxyvitamin D (25OHD), and magnesium (Mg) could be used to characterize the metabolically healthy obese (MHO) phenotype.

Methods:: This study included 27 overweight or obese participants (14 men/13 women) classified as MHO ( n = 14) or metabolically unhealthy obese (MUO) ( n = 13) based on the presence or absence of metabolic abnormalities, determined by percentage body fat, percentage trunk fat, and waist circumference.

Prevalence and potential factors associated with overweight and obesity status in adults with intellectual developmental disorders.

Background: The prevalence of being overweight and obese is increasing not just in the general population but also in individuals with intellectual disability (ID). Therefore, a need to identify factors contributing to overweight/obesity arises as this population is escalating.

Materials And Methods: This narrative review article summarizes pertinent research focusing on prevalence and the potential factors associated with overweight and obesity in adults with intellectual disability during the past decade.

Nutritional status of individuals with autism spectrum disorders: do we know enough?

The incidence of individuals with autism spectrum disorders (ASDs) is on the rise; therefore, well-timed screening is important. Given that this is a nutritionally vulnerable population, it is imperative to conduct a detailed nutritional assessment so that timely and intensive interventions can be recommended. This review article summarizes the research, focusing on the nutritional status of individuals with ASDs based on their anthropometric measurements, biomarkers, and dietary assessments.

Benchmarking a Home-Delivered Meal Program's Annual Satisfaction Survey: A Metropolitan Area Neighborhood Nutrition Alliance (MANNA) Initiative in Philadelphia.

The Metropolitan Area Neighborhood Nutrition Alliance (MANNA) is a community-based organization providing home-delivered meals in Philadelphia, Pennsylvania to individuals at acute nutritional risk and experiencing a life-threatening illness, independent of age or income. The challenge MANNA faces, like other community-based organizations, is to demonstrate effective services by benchmarking with other organizations. This article reports how MANNA benchmarked results of their annual satisfaction survey against the 2013 National Survey of Older Americans Act Program.

Nutritional rehabilitation in anorexia nervosa: review of the literature and implications for treatment.

Restoration of weight and nutritional status are key elements in the treatment of anorexia nervosa (AN). This review aims to describe issues related to the caloric requirements needed to gain and maintain weight for short and long-term recovery for AN inpatients and outpatients.We reviewed the literature in PubMed pertaining to nutritional restoration in AN between 1960-2012.

Psychoactive effects of tasting chocolate and desire for more chocolate.

The purpose of this study was to characterize the psychoactive effects of tasting chocolate and to evaluate the contribution of the main chocolate components to the desire to consume more of it. A total of 280 participants, (F-155; M=125) ranging in age from 18-65, completed the study. Participants were randomly assigned to taste 12.

Use of an operant task to estimate food reinforcement in adult humans with and without BED.

Objective: The purpose of this study was to demonstrate the utility of food-reinforced operant task performance in modeling binge-eating disorder (BED). We hypothesized that food reinforcement after a caloric preload would be related to BED status, but not hunger.

Methods And Procedures: We investigated the association between reports of hunger, binge tendency, and food reinforcement in a sample of 18 women (12 non-BED, 7 lean, 5 obese, and 6 obese BED).

Combined effects of methamphetamine and zolpidem on performance and mood during simulated night shift work.

Individuals who work irregular or rotating shifts often use stimulants and sedatives to offset shift-change-related mood and performance decrements. During this simulated shift work study the acute effects of the stimulant, methamphetamine were examined, and the effects of the hypnotic, zolpidem, and the combination were assessed during the shift after drug administration. Eight volunteers completed this 21-day, within-participant, residential laboratory study during which they received a single oral methamphetamine dose (0 or 10 mg) 1 h after waking, i.

Calcium and magnesium ATPase activities in women with varying BMIs.

Objective: Intracellular calcium (Ca) is increased in obese humans, and magnesium (Mg)-ATPase activity is increased in monosodium glutamate-induced obese rats. The aims of this study were to test the hypotheses that Ca-ATPase activity is negatively correlated with BMI, and that Mg-ATPase activity is positively correlated with BMI and Ca-ATPase activity in obese women.

Research Methods And Procedures: Thirty healthy adult women, with BMIs of 20 to 40, donated a single sample of whole blood and were interviewed as to medical history and family history of obesity.

Marijuana withdrawal in humans: effects of oral THC or divalproex.

Abstinence following daily marijuana use can produce a withdrawal syndrome characterized by negative mood (eg irritability, anxiety, misery), muscle pain, chills, and decreased food intake. Two placebo-controlled, within-subject studies investigated the effects of a cannabinoid agonist, delta-9-tetrahydrocannabinol (THC: Study 1), and a mood stabilizer, divalproex (Study 2), on symptoms of marijuana withdrawal. Participants (n=7/study), who were not seeking treatment for their marijuana use, reported smoking 6-10 marijuana cigarettes/day, 6-7 days/week.

Methamphetamine attenuates disruptions in performance and mood during simulated night-shift work.

Rationale: Increased sleepiness while working and sleep disruptions are common complaints among shift workers. Consequently, shift workers may be more susceptible to diminished performance and work-related accidents.

Objective: To examine the effects of the central nervous system stimulant methamphetamine on psychomotor task performance, subjective effects, and food intake during shift work under laboratory conditions.
