(Press-News.org) London, UK (1st June, 2015) - Factors influencing food intake have, and continue to be, a hotly contested subject. A new paper published today in the SAGE journal, Journal of Health Psychology (JHP), suggests that disrupted sleep could be one factor contributing to excessive food intake and thus leading to long term chronic health damage in both adults and children.
In a special issue on Food, Diets, and Dieting, the paper explores how a bad night's sleep - something that affects millions of people worldwide - can affect eating habits and behaviors. Though it is well-known that a bad night's sleep can affect our ability to perform daily duties, what is less known is how disrupted sleep can influence both our food choices and intake.
"It is well recognized that food intake is implicated in many chronic health issues including obesity, diabetes and heart disease, and diet is often a target of treatment to prevent the onset of these conditions", commented the researchers Alyssa Lundahl and Timothy D Nelson of the University of Nebraska- Lincoln, USA. However, they continued: "understanding the mechanisms linking disrupted sleep patterns to increased food intake is important for informing both prevention and treatment interventions for chronic health conditions."
Food intake is driven by biological, emotional, cognitive and environmental factors. Though diet is important to consider in the treatment for chronic health disorders associated with food intake, a closer look should be given to how sleep affects these factors. Lundahl and Nelson argue that these mechanisms are heavily altered and influenced by sleep patterns. For example, after a bad night's sleep, the hormone controlling appetite is affected, emotional stress is greater, more food is desired to compensate for lack of energy and impulsivity is increased, all of which affect the amount of food that you would consume in a day. They conclude:
"Health psychologists should be mindful of the link between sleep and eating, and sleep should be actively considered in efforts to modify dietary behavior."
Dr David Marks, editor of JHP, stated:
"The research stimulated by Lundahl and Nelson has important treatment implications for health conditions often treated with dietary interventions and illustrates the need for research to empirically examine the underlying mechanisms of food intake. It is important for people to be aware the findings of this study so that if they suffering from lack of sleep, they can take greater care to consider the quality and quantity of food that they are consuming."

Journal of Health Psychology is a leading international peer reviewed journal that aims to support and help shape research in health psychology from around the world. It provides a platform for traditional empirical analyses as well as more qualitative and/or critically oriented approaches. It also addresses the social contexts in which psychological and health processes are embedded. This journal is a member of the Committee on Publication Ethics (COPE). http://hpq.sagepub.com/
ANN ARBOR, Mich. - Can a routine hospital stay upset the balance of microbes in our bodies so much that it sets some older people up for a life-threatening health crisis called sepsis? A new University of Michigan and VA study suggests this may be the case.
It shows that older adults are three times more likely to develop sepsis -- a body-wide catastrophic response to infection -- in the first three months after leaving a hospital than at any other time.
What's more, the risk of sepsis in that short post-hospital time is 30 percent higher for people whose original hospital ...
There are some bad memories -- whether of a crime or a painful life event -- that we'd rather not recall. New research shows that people can successfully inhibit some incriminating memories, reducing the memories' impact on automatic behaviors and resulting in brain activity similar to that seen in "innocent" participants.
The research is published in Psychological Science, a journal of the Association for Psychological Science.
"In real life, many individuals who take memory detection tests want to distort their results. Using a lab-based crime simulation, we examined ...
This news release is available in French. The Drosophila, the so-called fruit fly, attends all day long to its activities. It flutters, has naps, lays its eggs or emerges from the pupa, the stage of metamorphosis preceding maturity. At the University of Geneva (UNIGE), Switzerland, the team of the researcher in biology Emi Nagoshi is closely interested in this insect, used as a model organism for the study of circadian rhythms in the animal kingdom. The researcher's group discovered that the main clock of the Drosophila, formed by neurons clustered in various regions ...
Viewed from above, our solar system's planetary orbits around the sun resemble rings around a bulls-eye. Each planet, including Earth, keeps to a roughly circular path, always maintaining the same distance from the sun.
For decades, astronomers have wondered whether the solar system's circular orbits might be a rarity in our universe. Now a new analysis suggests that such orbital regularity is instead the norm, at least for systems with planets as small as Earth.
In a paper published in the Astrophysical Journal, researchers from MIT and Aarhus University in Denmark ...
Beginning readers who focus on letter-sound relationships, or phonics, instead of trying to learn whole words, increase activity in the area of their brains best wired for reading, according to new Stanford research investigating how the brain responds to different types of reading instruction.
In other words, to develop reading skills, teaching students to sound out "C-A-T" sparks more optimal brain circuitry than instructing them to memorize the word "cat." And, the study found, these teaching-induced differences show up even on future encounters with the word.

(PHILADELPHIA) -- Despite advances in managing and curing some forms of breast cancer, women whose disease becomes metastatic have fewer effective options. A new phase 3 study in some of the most difficult-to-treat patients, women with endocrine-resistant disease, showed that the newly approved drug, palbociclib, more than doubled the time to cancer recurrence for women with hormone-receptor (HR+) positive metastatic breast cancer. The results will be presented at the 2015 annual American Society of Clinical Oncology (ASCO, abstract LBA-502) and published in the New England ...
Anastrozole provides a significant benefit compared with tamoxifen in preventing recurrence after a lumpectomy and radiation therapy in postmenopausal women ages 60 years or younger who had DCIS (ductal carcinoma in situ), a common diagnosis of non-invasive breast cancer. In women over age 60, it works as well as tamoxifen. These findings were presented today at the 2015 ASCO Annual Meeting in Chicago. The benefit reported in this trial appeared later in follow up of the women in the study.
"This study provides a new option for postmenopausal women undergoing treatment ...
DURHAM, N.C. - A modified poliovirus therapy that is showing promising results for patients with glioblastoma brain tumors works best at a low dosage, according to the research team at Duke's Preston Robert Tisch Brain Tumor Center where the investigational therapy is being pioneered.
The dosage findings for the first 20 patients in the phase 1 trial will be presented at the American Society of Clinical Oncology annual meeting in Chicago at the end of the month (abstract #2068).
"The purpose of a phase 1 trial is to identify the optimal dose to minimize toxicity," said ...
Queensland scientists have discovered two more species of suicidally-sexed marsupials and one is already destined for the threatened list.
Queensland University of Technology's (QUT) Dr Andrew Baker and his team have named two new species of Dusky Antechinus. One new species was discovered in remote, south-eastern Tasmania and another mainland form was raised to species status.
The team has now discovered five new species of antechinus in the past three years, a 50 per cent increase in diversity within this long-known genus of mammals.
However, the researchers believe ...
