Fast food may expose consumers to phthalates
April 13, 2016 07:16 AM - George Washington University via EurekAlert!
People who reported consuming more fast food in a national survey were exposed to higher levels of potentially harmful chemicals known as phthalates, according to a study published today by researchers at Milken Institute School of Public Health (Milken Institute SPH) at the George Washington University. The study, one of the first to look at fast-food consumption and exposure to these chemicals, appears in the journal Environmental Health Perspectives.
Better long-term outcomes for married cancer patients
April 11, 2016 11:51 AM - WILEY via EurekAlert
New research has uncovered a link between being married and living longer among cancer patients, with the beneficial effect of marriage differing by race/ethnicity and place of birth. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings have important public health implications, given the rising numbers of unmarried individuals in the United States in addition to the growing aging population.
For the analysis, a team led by Scarlett Lin Gomez, PhD, of the Cancer Prevention Institute of California, and María Elena Martínez, PhD, of the University of California, San Diego School of Medicine, assessed information on nearly 800,000 adults in California who were diagnosed in 2000 to 2009 with invasive cancer and were followed through 2012.
Using moss as a bioindicator of air pollution
April 8, 2016 07:16 AM - USDA Forest Service via EurekAlert!
Moss growing on urban trees is a useful bio-indicator of cadmium air pollution in Portland, Oregon, a U.S. Forest Service Pacific Northwest Research Station-led study has found. The work--the first to use moss to generate a rigorous and detailed map of air pollution in a U.S. city--is published online in the journal Science of the Total Environment.
Illegal gold mining in Brazil exposing indigenous peoples to high levels of mercury
April 5, 2016 11:52 AM - Sarina Kidd / Survival International, The Ecologist
Illegal gold mining in the Amazon has a devastating effect on indigenous peoples, writes Sarina Kidd. First the miners bring disease, deforestation and even murder. Then long after they have gone, communities are left to suffer deadly mercury poisoning. Now the UN has been called on to intervene.
In Brazil, new statistics reveal alarming rates of mercury poisoning amongst the Yanomami and Yekuana. 90% of Indians in one community are severely affected, with levels far above that recommended by the WHO.
Mercury poisoning is devastating tribal peoples across Amazonia, Survival International has warned.
Eat your walnuts today!
April 4, 2016 08:22 AM - EDELMAN SEATTLE via EurekAlert
Initial findings from the Walnuts and Healthy Aging (WAHA) study presented at Experimental Biology 2016 (EB) indicate that daily walnut consumption positively impacts blood cholesterol levels without adverse effects on body weight among older adults. The WAHA study is a dual site two-year clinical trial conducted by researchers from the Hospital Clinic of Barcelona and Loma Linda University and is aimed at determining the effect of walnuts on age-related health issues.
"Given walnuts are a high-energy food, a prevailing concern has been that their long term consumption might be associated with weight gain," said Dr. Emilio Ros, director of the Lipid Clinic, Endocrinology & Nutrition Service at the Hospital Clinic of Barcelona. "The preliminary results of the WAHA study demonstrate that daily consumption of walnuts for one year by a sizable cohort of aging free-living persons has no adverse effects on body weight. They also show that the well-known cholesterol-lowering effect of walnut diets works equally well in the elderly and is maintained in the long term. Acquiring the good fats and other nutrients from walnuts while keeping adiposity at bay and reducing blood cholesterol levels are important to overall nutritional well-being of aging adults. It's encouraging to see that eating walnuts may benefit this particular population."
Scotland shuts down its last coal-fired electric power plant
April 2, 2016 08:16 AM - s.e. smith, Care2
After nearly 50 years of service, Scotland’s last coal-fired power plant — Longannet Power Station — has finally gone offline, putting an end to over 100 years of burning coal for electricity.
It’s an important moment for Scottish Power, which looks ahead to clean power initiatives with the goal of going all-renewable by 2020,
But it’s also a very symbolic action for the world. Hopefully other nations will follow suit, creating a domino effect as country by country eliminates its coal plants — like the one above — in favor of renewable alternatives.
Lower indoor temperatures in winter correlate with thinner waistlines
April 1, 2016 05:16 PM - THE ENDOCRINE SOCIETY via EurekAlert.
Elderly adults are bigger around the middle when they turn up the heat inside their homes during the cold season and have smaller waistlines when their homes stay cool, new research finds. Investigators from Japan will present their study results Friday at the Endocrine Society's 98th annual meeting in Boston.
"Although cold exposure may be a trigger of cardiovascular disease, our data suggest that safe and appropriate cold exposure may be an effective preventive measure against obesity," said the study's lead investigator, Keigo Saeki, MD, PhD, of Nara Medical University School of Medicine Department of Community Health and Epidemiology, Nara, Japan.
Cold exposure activates thermogenesis, to generate body heat, in brown fat. This type of fat is the good calorie-burning fat that prior research found most humans have. However, Saeki said the association between the amount of cold exposure and obesity in real life remains unclear.
Going vegetarian could save emissions and prevent 8 million deaths a year
March 31, 2016 06:51 PM - Marco Springmann, The Ecologist
Oxford researchers have quantified the benefits of the world becoming vegetarian, writes Marco Springmann. Their study shows that simple changes - like moving to diets low in meat and high in fruit and vegetables - could lead to significant reduction in mortality and health care costs, while cutting food sector greenhouse gas emissions by two thirds.
Should we be feeding food waste to livestock?
March 30, 2016 06:39 AM - Gina-Marie Cheeseman , Triple Pundit
Food waste is a huge global problem. About a third of the food produced globally for human consumption, approximately 1.3 billion tons each year, is wasted or lost, according to the U.N. Food and Agriculture Organization (FAO). Food losses in industrialized countries add up to roughly $680 billion, with $310 billion in losses in developing countries. Produce (fruits and vegetables plus roots and tubers) have the highest rates of waste.
Taiwan has a simple solution to reduce food waste: Feed it to livestock. The Guardian reports that Taiwan is “one of a handful of countries that have institutionalized the practice” of feeding food scraps to livestock. About two-third’s of the country’s food waste is fed to its 5.5 million pigs. Pigs are Taiwan’s biggest source of meat.
“We realized there was a lot of kitchen waste and that if we put it in incinerators it would hamper incineration because it’s wet,” Chiang Tsu-nong, deputy inspector general with the government’s Bureau of Environmental Inspection, told the Guardian. “And Taiwan’s land is limited, so if you build a landfill or an incinerator people will protest.”
The past, present and future of African dust
March 28, 2016 07:19 AM - National Center for Scientific Research
So much dust is scattered across the planet by the winds of the Sahara that it alters the climate. However, the emission and transport of this dust, which can reach the poles, fluctuate considerably. Although many hypotheses have been put forward to explain this phenomenon, no unambiguous relationship between this dust and the climate had been established until now. According to research carried out by a French-US team of researchers from LATMOS(CNRS/UVSQ/UPMC), CNRM(CNRS/Météo-France) and SIO3, meteorological events such as El Niño and rainfall in the Sahel have an impact on dust emission, by accelerating a Saharan wind downstream of the main mountain massifs of Northwest Africa. The scientists have also developed a new predictive model showing that emissions of Saharan dust will decline over the next hundred years. Their work is published in the 24 March 2016 issue of the journal Nature.
