The advantages of being a morning person
April 1, 2015 01:40 PM - Roger Greenway, ENN
There are many advantages of getting a good nights sleep. Turns out, the advantages are less if you are a night owl instead of a morning person.
Night owls are more likely to develop diabetes, metabolic syndrome and sarcopenia than early risers, even when they get the same amount of sleep, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
The study examined the difference between night and morning chronotypes, or a person's natural sleep-wake cycle. Staying awake later at night is likely to cause sleep loss, poor sleep quality, and eating at inappropriate times, which might eventually lead to metabolic change.
Study suggests methane in drinking water is unrelated to fracking
March 31, 2015 02:00 PM - Eric Hand, Science/AAAS
Fracking doesn’t appear to be allowing methane to seriously contaminate drinking water in Pennsylvania, a new study finds—contrary to some earlier, much publicized research that suggested a stronger link. But the lead authors of the two bodies of research are sparring over the validity of the new results.
Lunch apparently not that appealing to children anymore
March 30, 2015 07:32 AM - Nestle via EurekAlert.
According to new analysis of data from the 2009-2012 National Health and Nutrition Examination Survey (NHANES) that evaluated eating patterns of 3,647 children ages 4-13 years, skipping lunch is a common practice among children and adolescents, with 13% of younger children and 17% of 9-13 year olds skipping lunch on a given day. The study found that the behavior persisted throughout the week with nearly a quarter (approximately 23%) of 9-13 year olds skipping lunch on the weekends. These findings, part of Nestlé's new Kids Nutrition & Health Study (KNHS), were presented today at a poster session entitled "What Happened to Lunch? Dietary Intakes of 4-13 Year Old Lunch Consumers and Non-Consumers in the United States" at the American Society of Nutrition conference.
These findings are of particular concern given that lunch skippers had lower intakes of nutrients, including calcium and fiber, than lunch consumers. In addition, the data show that for some children, the lunch meal was primarily responsible for the higher essential nutrient intakes of vitamin D, potassium and magnesium, as well as a nutrient of concern, sodium.
Antioxidant Effects differ by Leaf Color
March 27, 2015 01:47 PM - University of the Basque Country
Lettuce, one of the indispensable vegetables in the Mediterranean diet, is a food that greatly benefits health, mainly because it is rich in antioxidants. But not all lettuce varieties have the same antioxidant effect. According to a study led by the researcher Usue Pérez-López of the Department of Plant Biology and Ecology of the UPV/EHU's Faculty of Science and Technology, the colour of the leaves of these vegetables determines the speed at which their compounds act. So lettuces with green leaves have antioxidants that react more slowly while red-leaf ones have a faster effect. The results of this study have been set out in a paper "Phenolic Composition and Related Antioxidant Properties in Differently Coloured Lettuces: A Study by Electron Paramagnetic Resonance (EPR) Kinetics" recently published by the ‘Journal of Agricultural and Food Chemistry'.
Which diet has the smallest carbon footprint?
March 26, 2015 01:20 PM - Spanish Foundation for Science and Technology, via EurekAlert!
The health benefits of the Mediterranean diet are well-known. As well as being healthier, a recent article concludes that the menu traditionally eaten in Spain leaves less of a carbon footprint than that of the US or the United Kingdom. The consequences of climate change range from species extinction to sea-level increases and the spread of diseases. For this reason, researchers have been struggling for years to alleviate its effects, even limiting the pollution caused by food consumption.
Are you getting enough Zinc in your diet?
March 24, 2015 09:14 AM - Roger Greenway, ENN
Zinc is an important part of the human diet. You get it in Cashews, spinach, beef, shrimp, flax seed, Oysters, garlic, lima beans peanuts, turkey, Salmon, Pork, Brown rice and other foods. These are not listed in any particular order.
Zinc, is an important mineral in human health, that appears to affect how the immune system responds to stimulation, especially inflammation, new research from Oregon State University shows.
Zinc deficiency could play a role in chronic diseases such as cardiovascular disease, cancer and diabetes that involve inflammation. Such diseases often show up in older adults, who are more at risk for zinc deficiency.
“When you take away zinc, the cells that control inflammation appear to activate and respond differently; this causes the cells to promote more inflammation,” said Emily Ho, a professor and director of the Moore Family Center for Whole Grain Foods, Nutrition and Preventive Health in the OSU College of Public Health and Human Sciences, and lead author of the study.
United Nations warns on pesticides
March 23, 2015 09:55 AM - EurActiv
The UN's International Agency for Research on Cancer (IARC) said Friday (20 March) that three pesticides, including the popular weed killer Roundup, were "probably" carcinogenic and two others, which have already been outlawed or restricted, were "possibly" so.
IARC classified the herbicide glyphosate – the active ingredient in Roundup – and the insecticides malathion and diazinon as "probably carcinogenic" on the basis of "limited evidence" of cancer among humans.
Stinging nettle chemical improves cancer drug
March 20, 2015 02:20 PM - University of Warwick
A cancer drug could be made 50 times more effective by a chemical found in stinging nettles and ants, new research finds. Researchers at the University of Warwick found that when the chemical, Sodium Formate, is used in combination with a metal-based cancer treatment it can greatly increase its ability to shut down cancer cells.
NASA using space radar to track groundwater pollution risks
March 20, 2015 05:25 AM - Roger Greenway, ENN
Water is our most precious natural resource. Without clean water to drink human populations cannot exist. But our water supplies are under constant assault from anthropogenic pollution.
When pollutants get into groundwater, they can stay there for decades. Cleanup efforts are difficult, expensive and not always successful. It would be better to protect groundwater from contamination in the first place, but risks to groundwater are moving targets. Although unchanging factors such as porous soil or shallow aquifer depth play a role, the greatest risk comes from the source of the pollutants: people. And people are always moving. A growing city, in particular, usually means a growing threat to groundwater quality. To lock on to the moving target of groundwater risk, planners worldwide need up-to-date information on how people are changing the land surface.
A bright side to aging
March 19, 2015 06:56 AM - Northwestern University
Hollywood has given moviegoers many classic portrayals of grumpy old men. But new research suggests that getting older doesn’t necessarily make people cynical and suspicious.
Instead, trust tends to increase as people age, a development that can be beneficial for well-being, according to two new large-scale studies by researchers at Northwestern University and the University at Buffalo.
“When we think of old age, we often think of decline and loss,” said study co-author Claudia Haase, an assistant professor of Human Development and Social Policy at Northwestern’s School of Education and Social Policy.
