New York, Jan 17 (AP/UNB) — A hamburger a week, but no more — that's about as much red meat people should eat to do what's best for their health and the planet, according to a report seeking to overhaul the world's diet.
Eggs should be limited to fewer than about four a week, the report says. Dairy foods should be about a serving a day, or less.
The report from a panel of nutrition, agriculture and environmental experts recommends a plant-based diet, based on previously published studies that have linked red meat to increased risk of health problems. It also comes amid recent studies of how eating habits affect the environment. Producing red meat takes up land and feed to raise cattle, which also emit the greenhouse gas methane.
John Ioannidis, chair of disease prevention at Stanford University, said he welcomed the growing attention to how diets affect the environment, but that the report's recommendations do not reflect the level of scientific uncertainties around nutrition and health.
"The evidence is not as strong as it seems to be," Ioannidis said.
The report was organized by EAT, a Stockholm-based nonprofit seeking to improve the food system, and published Wednesday by the medical journal Lancet. The panel of experts who wrote it says a "Great Food Transformation" is urgently needed by 2050, and that the optimal diet they outline is flexible enough to accommodate food cultures around the world.
Overall, the diet encourages whole grains, beans, fruits and most vegetables, and says to limit added sugars, refined grains such as white rice and starches like potatoes and cassava. It says red meat consumption on average needs to be slashed by half globally, though the necessary changes vary by region and reductions would need to be more dramatic in richer countries like the United States.
Convincing people to limit meat, cheese and eggs won't be easy, however, particularly in places where those foods are a notable part of culture.
In Sao Paulo, Brazil, systems analyst Cleberson Bernardes said as he was leaving a barbecue restaurant that letting himself eat just one serving of red meat a week would be "ridiculous." In Berlin, Germany, craftsman Erik Langguth said there are better ways to reduce greenhouse gas emissions, and dismissed the suggestion that the world needs to cut back on meat.
"If it hasn't got meat, it's not a proper meal," said Langguth, who is from a region known for its bratwurst sausages.
Before even factoring in the environmental implications, the report sought to sketch out what the healthiest diet for people would look like, said Walter Willett, one of its authors and a nutrition researcher at Harvard University. While eggs are no longer thought to increase risk of heart disease, Willett said the report recommends limiting them because studies indicate a breakfast of whole grains, nuts and fruit would be healthier.
He said everybody doesn't need to become a vegan, and that many are already limiting how much meat they eat.
"Think of it like lobster — something that I really like, but have a few times a year," Willett said.
Advice to limit red meat is not new, and is tied to its saturated fat content, which is also found in cheese, milk, nuts and packaged foods with coconut and palm kernel oils. The report notes most evidence on diet and health is from Europe and the United States. In Asian countries, a large analysis found eating poultry and red meat (mostly pork) was associated with improved lifespans. That might be in part because people might eat smaller amounts of meat in those countries, the report says.
Ioannidis of Stanford noted nutrition research is often based on observational links between diet and health, and that some past associations have not been validated. Dietary cholesterol, for example, is no longer believed to be strongly linked to blood cholesterol.
The meat and dairy industries also dispute the report's recommendations, saying their products deliver important nutrients and can be part of healthy diets.
Andrew Mente, a nutrition epidemiology researcher at McMaster University, urged caution before making widespread dietary recommendations, which he said could have unintended consequences.
Still, the EAT-Lancet report's authors say the overall body of evidence strongly supports reducing red meat for optimal health and shifting toward plant-based diets. They note the recommendations are compatible with the U.S. dietary guidelines, which say to limit saturated fat to 10 percent of calories.
While people in some poorer counties may benefit from getting more of the nutrients in meat and dairy products, the report says they shouldn't follow the path of richer countries in how much of those foods they eat in coming years.
Though estimates vary, a report by the United Nations said livestock is responsible for about 15 percent of the world's gas emissions that warm the climate.
Robbie Andrew, a senior researcher at CICERO Center for International Climate Research in Norway, said farming practices that make animals grow faster and bigger may help limit emissions. But he said cows and other ruminant animals nevertheless produce a lot of methane, a powerful greenhouse gas.
"It's very difficult to get down these natural emissions that are part of their biology," Andrew said.
The environmental benefits of giving up red meat depend on what people eat in its place. Chicken and pork produce far fewer emissions than beef, Andrew said, adding that plants in general have among the smallest carbon footprints.
Brent Loken, an author of the EAT-Lancet report, said the report lays out the parameters of an optimal diet, but acknowledged the challenge in figuring out how to work with policy makers, food companies and others in tailoring and implementing it in different regions.
Washington, Jan 17 (AP/UNB) — How did the earliest land animals move? Scientists have used a nearly 300-million-year old fossil skeleton and preserved ancient footprints to create a moving robot model of prehistoric life.
Evolutionary biologist John Nyakatura at Humboldt University in Berlin has spent years studying a 290-million-year-old fossil dug up in central Germany's Bromacker quarry in 2000. The four-legged plant-eater lived before the dinosaurs and fascinates scientists "because of its position on the tree of life," said Nyakatura. Researchers believe the creature is a "stem amniote" — an early land-dwelling animal that later evolved into modern mammals, birds and reptiles.
Scientists believe the first amphibious animals emerged on land 350 million years ago and the first amniotes emerged around 310 million years ago.
The fossil, called Orabates pabsti, is a "beautifully preserved and articulated skeleton," said Nyakatura. What's more, scientists have previously identified fossilized footprints left by the 3-foot-long (90 cm) creature.
Nyakatura teamed up with robotics expert Kamilo Melo at the Swiss Federal Institute of Technology in Lausanne to develop a model of how the creature moved. Their results were published Wednesday in the journal Nature.
The researchers built a life-size replica of the prehistoric beast — "we carefully modeled each and every bone," said Nyakatura — and then tested the motion in various ways that would lead its gait to match the ancient tracks, ruling out combinations that were not anatomically possible.
They repeated the exercise with a slightly-scaled up robot version , which they called OroBOT. The robot is made of motors connected by 3D-printed plastic and steel parts. The model "helps us to test real-world dynamics, to account for gravity and friction," said Melo. The team also compared their models to living animals, including salamanders and iguanas.
Technology such as robotics, computer modeling and CT scans are transforming paleontology, "giving us ever more compelling reconstructions of the past," said Andrew Farke, curator at the Raymond M. Alf Museum of Paleontology in Claremont, California, who was not involved in the study.
Based on the robot model, the scientists said they think the creature had more advanced locomotion than previously thought for such an early land animal. (Think more scampering than slithering.)
"It walked with a fairly upright posture," said Melo. "It didn't drag its belly or tail."
University of Maryland paleontologist Thomas R. Holtz, who was not involved in the study, said the research suggests "an upright stance goes further back than we originally thought."
Stuart Sumida, a paleontologist at California State University in San Bernardino and part of the initial team that excavated Orobates fossils, called it "an exciting study." Sumida, who was not involved in the robot project, said the work provided "a much more confident window in to what happened long ago. It isn't a time machine, but Nyakatura and colleagues have given us a tantalizing peek."
Dhaka, Jan 16 (UNB) – Priota Iftekhar, the winner of ‘Miss Culture Worldwide-2018’, says her goal is to inform the world about the culture and heritage of Bangladesh.
“I’m elated at such an achievement on the Victory Day,” she told a media briefing, her first since the competition in Zimbabwe in December last year.
It was Bangladesh’s first win in the competition.
Priota shared her experiences at a press conference arranged by Surecell Medical at Jatiya Press Club on Wednesday.
“My main goal was to highlight Bangladesh and its culture. And I did it,” she said. “The feeling of hoisting the national flag at an international event cannot be described in words.”
“I dressed as a female freedom fighter in the final stage of the competition to represent my country,” Priota said. She suffered a leg injury before the competition but took part ignoring the doctor’s warning.
“I never thought that I would be the champion. I thought at best I would reach top three,” she added.
Priota established ‘Flag Girl’ in 2008 to help women travellers at home and abroad. It currently has over 200 members.
She was also a recipient of Joy Bangla Youth Award-2018.
Priota, also the ambassador of Bangladesh Tourism Corporation, starred in a telefilm titled “Impossible five” back in 2013 and later in Sri Lankan film “Pani Makuluwo” in 2017.
Dhaka, Jan 16 (UNB) - Adventure movie in Bangla ‘Hridoyer Rongdhonu’ (Life in Rainbow) will be premiered at 17th Dhaka International Film Festival 2019 on Thursday.
The movie directed by Razibul Hossain will be screened at 7:30 pm at the Public Library Auditorium in the city as part of the ongoing month-long film festival.
The movie in ‘Hridoyer Rongdhonu’ (Life in Rainbow) was selected as “View Corner” at Goa Film Bazaar in last year.
The director told UNB that the movie will be released very soon in the theaters across the country.
Asian Institute of Media and Communication Bangladesh (AIMC) informed that its first Asian Premier was held on 24th November at QUBE 2 Hall at 2 pm in India tourist city Goa.
'Life in Rainbow' is a story of four aspiring youth (3 boys and 1 girl). They are friends. They have everything in their life. One day their life turns into a mystery. They got a call from a mysterious character as the mysterious character knew everything about them (Mina, Shams, Shojon and Khing) and their desire, expectations, inner calls etc.
He offered them a trip, "If you dare enough to take any challenges you can join a trip, a trip to an unknown destination!" They never thought this journey would make them a new person with enlightens of inner knowledge, skills and personality.
After two years of straggling for censorship certificate from Bangladesh Film Censor Board, the film got finally received it on October 23, 2018.
