Dietary fat under fire

Researchers from Universite Laval question current dietary recommendations and call for a reassessment of the associations between saturated fat and cardiovascular disease risk

2014-10-08
(Press-News.org) This news release is available in French.

The association between saturated fat and cardiovascular risk has become a hot topic in nutrition. Researchers at the Institute of nutrition and functional foods (INAF) of Université Laval are calling for a review of dietary recommendations on saturated fat (SFA) in relation to cardiovascular disease (CVD).

In a Comment paper, published today in the journal Applied Physiology, Nutrition, and Metabolism the authors provide a number of arguments for the urgency to re-assess the association between dietary saturated fat and cardiovascular risk.

As there are currently no harmonized dietary guidelines in Canada for the prevention of CVD, the authors urge the Canadian nutrition community to revisit the guidelines and develop recommendations that reflect both the current food reality and the latest science.

"We believe that evidence regarding the impact of dietary SFA on CVD risk factors other than LDL-C and evidence regarding whole foods rather than just SFA, both from clinical as well as epidemiological perspectives, need to be considered in the future," write the authors in the paper's conclusion.

"Because we believe that focussing on SFA in dietary guidelines may not have yielded full benefits in terms of cardiovascular prevention, considering the impact of individual SFA on CVD risk may also be an inappropriate route to undertake in the future."

INFORMATION: The paper "It is time to revisit current dietary recommendations for saturated fat" was published today in the journal Applied Physiology, Nutrition, and Metabolism and is available Open Access.

Flies with colon cancer help to unravel the genetic keys to disease in humans

Flies with colon cancer help to unravel the genetic keys to disease in humans
2014-10-08
Researchers at the Institute for Research in Biomedicine (IRB Barcelona) have managed to generate a fruit fly (Drosophila melanogaster) model that reproduces human colon cancer. With two publications appearing in PLoS One and EMBO Reports, the IRB team also unveil the function of a key gene in the development of the disease. "The breakthrough is that we have generated cancer in an adult organism and from stem cells, thus reproducing what happens in most types of human cancer. This model has allowed us to identify subtle interactions in the development of cancer that are ...

Fruit flies reveal features of human intestinal cancer

Fruit flies reveal features of human intestinal cancer
2014-10-08
HEIDELBERG, 8 October 2014 – Researchers in Spain have determined how a transcription factor known as Mirror regulates tumour-like growth in the intestines of fruit flies. The scientists believe a related system may be at work in humans during the progression of colorectal cancer due to the observation of similar genes and genetic interactions in cultured colorectal cancer cells. The results are reported in the journal EMBO Reports. Colorectal cancer leads to more than half a million deaths worldwide each year. The disease originates in the epithelial cells of the ...

Supervisors' abuse, regardless of intent, can make employees behave poorly

Supervisors abuse, regardless of intent, can make employees behave poorly
2014-10-08
SAN FRANCISCO, Oct. 8, 2014 -- Employees who are verbally abused by supervisors are more likely to "act out" at work, doing everything from taking a too-long lunch break to stealing, according to a new study led by a San Francisco State University organizational psychologist. Even if the abuse is meant to be motivational -- like when a football coach berates his team or a drill sergeant shames her cadets -- the abused employees are still more likely to engage in counter-productive work behaviors, said Kevin Eschleman, assistant professor of psychology at SF State. The ...

Large chain restaurants appear to be voluntarily reducing calories in their menu items

2014-10-08
New research from the Johns Hopkins Bloomberg School of Public Health finds that large chain restaurants, whose core menu offerings are generally high in calories, fat and sodium, introduced newer food and beverage options that, on average, contain 60 fewer calories than their traditional menu selections in 2012 and 2013. Researchers say this could herald a trend in calorie reduction in anticipation of expected new federal government rules requiring large chain restaurants – including most fast-food places – to post calorie counts on their menus. The appearance ...

Universal screening for MRSA may be too costly

2014-10-08
PHILADELPHIA – (Oct. 8, 2014) – Numerous experts and policy makers have called for hospitals to screen patients for methicillin-resistant Staphylococcus aureus (MRSA) infections and isolate anyone testing positive to prevent the spread of these so-called "Superbugs" in healthcare settings. Several states have enacted laws requiring patients be screened for MRSA upon admission. Two new abstracts, scheduled for presentation on Friday at IDWeek, the annual scientific meeting for infectious disease specialists, found universal MRSA screening and isolation of ...

Childhood eating difficulties could be a sign of underlying psychological issues

2014-10-08
This news release is available in French. Researchers at the University of Montreal and its affiliated CHU Sainte-Justine children's hospital are warning parents that difficult eaters could have underlying psychological issues, as they have found that restrictive behaviours can appear before puberty. "Many researchers believe that bulimia only appears at adolescence, but our studies indicate that the problem can arises much earlier. It is possible that it is currently under-diagnosed due to a lack of awareness and investigation," explained clinical psychologist and ...

How dinosaurs divided their meals at the Jurassic dinner table

2014-10-08
How the largest animals to have ever walked the Earth fed, and how this allowed them to live alongside one another in prehistoric ecosystems is the subject of new research from the University of Bristol and the Natural History Museum, London. The sauropods – large, long-necked plant-eating dinosaurs such as Diplodocus and Brachiosaurus – dominated the land between 210 and 65 million years ago. They were the largest land animals of all time, with the biggest weighing 80 tonnes (more than 11 elephants) and would have needed vast amounts of food. Despite ...

The Lancet Psychiatry: Schools key to reaching the 1 in 10 children with mental health problems

2014-10-08
Schools are a vital way of reaching the 10–20% of children and young people across the globe who would benefit from some sort of mental health intervention, according to a new Series on mental health interventions in schools published in The Lancet Psychiatry. The Series highlights that childhood is an important window for intervention because around 75% of adults who access mental health services have had a diagnosable disorder before the age of 18 [1]. What is more, estimates from high-income countries (HICs) indicate that only 25% of children with a mental health ...

Working memory hinders learning in schizophrenia

Working memory hinders learning in schizophrenia
2014-10-08
PROVIDENCE, R.I. [Brown University] — A new study pinpoints working memory as a source of learning difficulties in people with schizophrenia. Working memory is known to be affected in the millions of people – about 1 percent of the population – who have schizophrenia, but it has been unclear whether that has a specific role in making learning more difficult, said study lead author and Brown University postdoctoral researcher Anne Collins. "We really tend to think of learning as a unitary, single process, but really it is not," said Collins, who along ...
