Toxic neighbors: Taking action to solve the climate crisis
Evidence mounts that gut bacteria can influence mood, prevent depression
Science magazine reports: Of all the many ways the teeming ecosystem of microbes in a person’s gut and other tissues might affect health, its potential influences on the brain may be the most provocative. Now, a study of two large groups of Europeans has found several species of gut bacteria are missing in people with depression. The researchers can’t say whether the absence is a cause or an effect of the illness, but they showed that many gut bacteria could…
OxyContin maker explored expansion into ‘attractive’ anti-addiction market
By David Armstrong, ProPublica, January 30, 2019 Not content with billions of dollars in profits from the potent painkiller OxyContin, its maker explored expanding into an “attractive market” fueled by the drug’s popularity — treatment of opioid addiction, according to previously secret passages in a court document filed by the state of Massachusetts. In internal correspondence beginning in 2014, Purdue Pharma executives discussed how the sale of opioids and the treatment of opioid addiction are “naturally linked” and that the…
Screen time has stunted the development of generations of children
The Guardian reports: A study has linked high levels of screen time with delayed development in children, reigniting the row over the extent to which parents should limit how long their offspring spend with electronic devices. Researchers in Canada say children who spent more time with screens at two years of age did worse on tests of development at age three than children who had spent little time with devices. A similar result was found when children’s screen time at…
In hunter-gatherer societies, excellent metabolic health is sustained by very active ways of living and a wide range of diets
The New York Times reports: Nutrition experts have long debated whether there is an optimal diet that humans evolved to eat. But a study published this month adds a twist. It found that there is likely no single natural diet that is best for human health. The research, published in the journal Obesity Reviews, looked at the diets, habits and physical activity levels of hundreds of modern hunter-gatherer groups and small-scale societies, whose lifestyles are similar to those of ancient…
New plant-focused diet would ‘transform’ planet’s future
The Guardian reports: The first science-based diet that tackles both the poor food eaten by billions of people and averts global environmental catastrophe has been devised. It requires huge cuts in red meat-eating in western countries and radical changes across the world. The “planetary health diet” was created by an international commission seeking to draw up guidelines that provide nutritious food to the world’s fast-growing population. At the same time, the diet addresses the major role of farming – especially…
How Trump is poisoning America
The New York Times reports: Had Donald J. Trump not won the presidency in 2016, millions of pounds of chlorpyrifos most likely would not have been applied to American crops over the past 21 months. It would not have sickened substantial numbers of farm workers, or risked what the Environmental Protection Agency’s own studies suggest could be continued long-term health problems for others exposed to the chemical at low levels. Widespread concerns about chlorpyrifos led to its removal for nearly…
Life expectancy declines in the U.S. but is increasing in most other developed nations
The Washington Post reports: Life expectancy in the United States declined again in 2017, the government said Thursday in a bleak series of reports that showed a nation still in the grip of escalating drug and suicide crises. The data continued the longest sustained decline in expected life span at birth in a century, an appalling performance not seen in the United States since 1915 through 1918. That four-year period included World War I and a flu pandemic that killed…
Wildfire smoke is becoming a nationwide health threat
An image from the International Space Station captures plumes of smoke from California wildfires on August 4, 2018. NASA Richard E. Peltier, University of Massachusetts Amherst The impacts of recent forest fires in California reach well beyond the burned areas. Smoke from the Camp Fire created hazardous air quality conditions in San Francisco, more than 170 miles to the southwest – but it didn’t stop there. Cross-country winds carried it across the United States, creating hazy conditions in locations as…
The health of an ecosystem (including your home) depends on its biodiversity
William Foster writes: Rob Dunn invites us on a safari in pursuit of the wildlife teeming on our bodies and in every corner of our homes. For him, the creatures that sprawl in the human navel and under the bathroom shower head elicit the kind of wonder most of us would feel only on seeing the denizens of Tanzania’s Ngorongoro Crater or the Great Barrier Reef off Australia. Dunn is more than an informed and entertaining commentator, a David Attenborough…
Doctors have become the tools of their tools
Atul Gawande writes: A 2016 study found that physicians spent about two hours doing computer work for every hour spent face to face with a patient—whatever the brand of medical software. In the examination room, physicians devoted half of their patient time facing the screen to do electronic tasks. And these tasks were spilling over after hours. The University of Wisconsin found that the average workday for its family physicians had grown to eleven and a half hours. The result…
Most American soldiers are overweight and underslept
Military Times reports: A 2018 RAND report on health promotion and disease prevention has painted a grim picture of the military’s physical fitness and sleep standards. The study, featuring roughly 18,000 randomly selected participants across each of the service branches, showed that almost 66 percent of service members are considered to be either overweight or obese, based on the military’s use of body mass index as a measuring standard. While the number of overweight service members is a cause for…
Trump administration tries to boost corporate profits by exposing Americans to radiation and toxins
The Associated Press reports: The Trump administration is quietly moving to weaken U.S. radiation regulations, turning to scientific outliers who argue that a bit of radiation damage is actually good for you — like a little bit of sunlight. The government’s current, decades-old guidance says that any exposure to harmful radiation is a cancer risk. And critics say the proposed change could lead to higher levels of exposure for workers at nuclear installations and oil and gas drilling sites, medical…
Time-restricted eating can overcome the bad effects of faulty genes and unhealthy diet
sukrit3d/Shutterstock.com By Satchin Panda, University of California San Diego Timing our meals can fend off diseases caused by bad genes or bad diet. Everything in our body is programmed to run on a 24-hour or circadian time table that repeats every day. Nearly a dozen different genes work together to produce this 24-hour circadian cycle. These clocks are present in all of our organs, tissues and even in every cell. These internal clocks tell us when to sleep, eat, be…
As wildfires rage, smoke chokes out farmworkers and delays some crops
NPR reports: On Mike Pink’s potato farm at dawn, the sun is an angry red ball low in the sky. This summer, wildfire smoke has blanketed much of the West for days and weeks. And that smoke has come between the sun and ripening crops. Pink watches as his year’s work tumbles onto a fast-moving belt and into a waiting semi truck. He’s got most of his 1,600-acre potato fields yet to harvest on his 3,000-acre farm, spread over about…
Climate change will make hundreds of millions more people suffer from nutritional deficiencies
The Guardian reports: Rising levels of carbon dioxide could make crops less nutritious and damage the health of hundreds of millions of people, research has revealed, with those living in some of the world’s poorest regions likely to be hardest hit. Previous research has shown that many food crops become less nutritious when grown under the CO2 levels expected by 2050, with reductions of protein, iron and zinc estimated at 3–17%. Now experts say such changes could mean that by…
