in one of the most important studies to date, researchers at Loma Linda University in California report that vegetarians survive meat eaters.

Among a group of 70,000 participants, the researchers found that vegetarians had a 12% lower risk of death compared to non-vegetarians. The effect was true for other specific vegetarian diets, the study, which is published in the journal JAMA Internal Medicine . For example, vegans also had a lower risk of death compared with nonvegetarians.

Vegetarian diets have been linked to the research before a low likelihood of developing chronic diseases such as heart disease or diabetes, but the underlying mechanisms are still under investigation. "We can not tell from this document being sure, but one of the most plausible potential reasons that contribute to this beneficial association is perhaps the absence or reduction of meat consumption," says Dr. Michael J. Orlich, director of preventive medicine residency at Loma Linda University.

red meat was fingers as a potential culprit because of its high levels of saturated fat and cholesterol this can clog arteries. in April, another study showed that carnitine compound also found in red meat, is metabolized by the human intestinal bacteria and fills the blood vessels.

Although ' there is a good amount of evidence linking red meat consumption to increased mortality, other factors could also be involved. "it could also be that consumption of various plant foods can be advantageously combined with reduced mortality, so we really want to discuss these things on the level of food in the future, "said Orlich.

Interestingly, the researchers also found that the association between vegetarian diets and lower mortality was higher in men than in women. The men had lower rates of cardiovascular disease and death from heart conditions. Women are not the same measurable reductions.

"I do not have strong speculation, but it could be that diet plays differently due to biological factors in men and women, "said Orlich, who plans to look deeper into what foods and specific nutrients may be responsible for the association. Understanding what motivates the link is complex, and it may be different for various groups and individuals. For example, a British study of vegetarianism in more than 47,250 participants did not find the same results in mortality. The fact that American vegetarians consume more fiber and vitamin C might be the reason, which emphasizes the need for a better understanding of how the longevity diet impacts.

Call Paleo Chic. The eating habits of cavemen have never been more popular. But should we take menus evidence of our ancestors?

The protein-heavy, principles low carb diet of Paleo arise in restaurants as HG SPLY Co. in Dallas and Hu Kitchen in New York; Paleo inspired new exotic products such as pemmican grass-fed beef, a Native American meat paste, hit the shelves. And Miley Cyrus celebrities Kobe Bryant are followers would greedy.

While the Paleo diet has been around for years, it is just gaining some momentum Mastodon-like. But many nutrition experts are not impressed. June 3, Scientific American ran a long history that ridiculed the Paleo diet as "half-baked". The magazine suggested that the caveman was imagining- movement "a tall, thin, torn and agile 30 years "was an invention.]

Similarly, US News, in its 2014 ranking of the" Best Diets overall, "announced that the Paleo diet was basically very, tied at No. 31 with Dukan diet. "experts questioned the diet on every measure," scolded the magazine.

What beef experts, so to speak, with the regime? When it surfaces in academia in the late 1970s and the popular diet books began emerging in the 1990s, the program was promoted as a way of life and a loss method weight, cousin to Dr. Atkins and the low-carb craze.

The theory behind the diet is simple: our hunter-gatherer ancestors who survived the meat and fish that has not been saturated with antibiotics or hormones stimulating growth, as well as fresh fruits and vegetables, were on track until the agricultural revolution introduced toxins in the food chain there are about 10,000 years. So the goal is for citizens of the 21st century lean back and back and eat the way primitive people made in the Paleolithic era, there are about two million years.

But dieticians find its debt, even fussy, requirements such as bonding with very lean, meats and pure plant unrealistic. As Scientific American said, "The Paleo diet is based on more privileged than logic. Hunter-fathers in the Paleolithic hunted and gathered because they had to. people at the Paleo diet try to eat as hunter-gatherers because they want to. "Any diet that restricts certain food groups and emphasizes other are not balanced, these experts say, and there is no solid scientific evidence to prove that Paleo-eaters live longer, or are healthier than those who do not follow the diet

Marlene Zuk, an evolutionary biologist at the University of Minnesota, has a different reproach in his new book, "Paleofantasy.. Qu'est- what evolution really says about sex, food, and how we live, "she rips most contemporary notions of our Paleolithic ancestors. "I have not written a diet book," she said, "and I do not want to tell people how to eat. But I want people to understand evolution."

But the Paleo crowd passionately defends his ancestral diet. Kellyann Petrucci, nutritional clinician who is the author of three "Dummies" books on popular lifestyle Paleo ( "Living Paleo", "Paleo Cookbook" and "Paleo Workouts), it offers the benefits of part A primitive habits. "I became interested in Paleo because when I hit 40 a few years ago, I fell and burned," she said. "I was gaining weight like crazy ... my skin was lifeless, my hair started thinning and I had no energy. When I followed the Paleo model, it was clear to me that something was going on a deep cellular level. Not only have I myself back, but a healthier and more dynamic version. "

Perhaps the most outspoken defender of Paleodom Chris Kresser, whose new book" Your code Paleo Personal "(read an excerpt here) provides a detailed roadmap for the lifestyle. Kresser who practices integrative and functional medicine in Berkeley, Cal., Assigns regime with restoring his own health after years of painful digestive disease. "Today, I am blessed with good health, a loving family and a thriving practice, "he said.

Kresser argues that in fact science supports Paleo principles. "There is a broad consensus among scientists that our Paleolithic ancestors consumed mainly meat, fish, vegetables, fruits, nuts, seeds and starchy tubers "He rejects the claim that the diet is too labor-intensive for the average person, or is difficult to find the ingredients of these previous regimes, citing a plethora of restaurants and new convenience foods such as gluten / sugar / soy-free beef jerky, kale chips and grain gluten-free crackers and deserts.

Over the past three years, he said he has treated 900 people in his office in Berkeley, California. "My practice has been closed to new patients for most of the past two years," he says, "because there is a high demand for clinicians who embrace Paleo in their work." Kresser said that the plan is booming in popularity because "Many people experience a profound change in their health after switching to Paleo and they are happy to share with others. This created one base, the movement of people wanting to get the word powerful word-of-mouth. "

This word is not enough, however. New York City nutritionist Jennifer Andrus sees wise nutritional principles in food, such as meats and lean fish, fruits and vegetables, but said that it is not necessary to go to extremes of Paleo crowd. "it eliminates dairy products, legumes and other foods that can be part of healthy diet." Although she shares the concerns of the people about Paleo food and modern convenience candy, she is also concerned about our current gluttony "I think that processed foods deserves criticism, but probably not because we have not evolved. most likely because we eat too much of it and most of it is empty nutritionally. "

Andrus suggests a common sense strategy, one that Kresser said in his book, he can take out." Some people like to comply with the 80/20 rule; if 80% of your diet is perfect, there is some leeway for the rest, "she said. After all," There is plenty of space between Paleo and a shit eating Pop-Tarts and McDonald . "

central heating feels good on windy winter nights, but a new study conducted by researchers from University College London suggests that keeping your home can be too soft you fat.

The idea is that the exposure to cold prompts humans to generate their own heat - by chills, for example, in extremely cold conditions - which, in turn, helps burn calories. When he is already toasty inside, we should not expend extra energy to get comfortable. The New York Times reports

Even in slightly colder conditions, such as in a cold room with the thermostat turned down to the 60 lowest, people produce additional heat without trembling. This process, called non-shivering thermogenesis, may involve a substance called brown fat than adults are in some areas, like the upper back and side of the neck. Unlike regular fat, which stores excess energy and calories, brown fat acts like an internal furnace that consumes a lot of calories, but it must first be activated - and cold temperatures make

.

The authors of the new study, published in the journal Reviews obesity noted that the average indoor temperatures have increased steadily in the United Kingdom and the United States in recent decades, central heating has become increasingly available - and obesity rates have increased too. The average temperature in British living rooms increased from 64.9 degrees to 70.3 degrees F F, from 1978 to 2008. Living in the United States have long been heated to at least 70 degrees F. In fact, average temperatures have increased throughout the house - and winter, people tend not to leave their homes much, at least not unless it's in a heated car.

"expectations increased time spent indoors, widespread access to central heating and air conditioning, and an increase in thermal comfort contribute to limit the range of temperatures we experience in daily life and reduce the time our bodies spend under mild thermal stress - meaning we burn less energy " said lead author Fiona Johnson in a statement. "This could have an impact on energy balance and ultimately have an impact on body weight and obesity."

Although humans are born with significant deposits of brown fat - whose main purpose is to regulate body temperature by burning energy for heating. - these stores decreased over time as adults our brown fat stores fell, having been replaced the more familiar white fat, the stuff that hangs over belt buckles and swings on the back of the arms.

Studies show, however, that the brown fat activity can be triggered even in adults. Thus, the Times asks: "Could lower the thermostat to make a noticeable difference in the weight of the people"

Dr. C. Ronald Kahn, a professor at Harvard Medical School? who did research on brown fat, said it could actually help with weight control over time, as long as people stick with it.

"When we put people in a room 60 degrees, they increase their energy expenditure of 100 or 200 calories a day if they are in light clothing, "as scrubs in the hospital, he said. "They are not shivering. They activate their brown fat."

Over a period of several weeks, they burned an extra 3,500 calories, which results in the loss of a book.

The problem, Dr. Kahn said, is that "most people will not stay at that temperature for a long time."

Learning to talk down fat conversation is an art. "One of the first things we teach women is the meaning fat-talk," says Sarah Williamson, director of educational initiatives at the Delta Delta Delta headquarters. One of the next things? "Healthy looks different for everyone," says Williamson. ( More about Time.com: You want good health? There are 10 Apps for That)

Williamson office for example, is an area all year nonfat conversation If an uneducated soul must wander in and join them for lunch, to proclaim, "Oh, I can not eat, I feel I'll. gain 10 pounds, "they are slightly cut off. "We say he is fat-talk-free here," says Williamson. Then they finished their lunch.
