For years, the government has been issuing guidelines about healthy eating choices. Now, a panel that advises the Agriculture Department is ready to recommend that you be told not only what foods are better for your own health, but for the environment as well. That means that when the latest version of the government's dietary guidelines comes out, it may push even harder than it has in recent years for people to choose more fruits, vegetables, nuts, whole grains and other plant-based foods — at the expense of meat....

The most common misconception among doctors, dieticians and personal trainers is that the missing mass has been converted into energy or heat. "There is surprising ignorance and confusion about the metabolic process of weight loss," says Professor Andrew Brown, head of the UNSW School of Biotechnology and Biomolecular Sciences. "The correct answer is that most of the mass is breathed out as carbon dioxide. It goes into thin air," says the study's lead author, Ruben Meerman, a physicist and Australian TV science presenter. ------------------- The second most frequently asked question is whether weight loss can cause global warming.

Now that global warming has been tamed by record breaking cold spells across the nation, former Vice-President Al Gore is looking for new worlds to conquer. That new world appears to be the establishment of a “national policy on food.” “Under current rules, what a person eats is largely left up to each person to decide,” Gore pointed out. “Judging from the rates of obesity, it seems clear that the idea that letting individuals choose what to eat is not working. It is way past time that experts in the field of nutrition be given the authority to determine healthier...

Nutrition and health in agriculturalists and hunter-gatherers 22. April 2009, 2:21 UhrLow-carb diets, Paleolithic diet, Paleopathologymreades139 comments 87 When I wrote the Overcoming the Curse of the Mummies chapter in Protein Power, I wrote mainly about the evidence of disease found in the mummies of ancient Egyptians and correlated this disease with their high-carbohydrate diet.  Along with all the material on mummies, which is the part everyone seems to remember, I wrote about a study done in the United States in the 1970s that persuasively demonstrated the superiority of the hunter diet as compared to an agricultural diet, which no...

If you think losing weight is enough to prevent Type 2 diabetes, don't get your hopes up. A new research report in September 2014 issue of The FASEB Journal, suggests that you don't have to be overweight to develop Type 2 diabetes. This study compared genetically identical twins-one heavier and one leaner-and found that after eating a fast-food meal, the circulating metabolites, including those related to Type 2 diabetes, were found in both individuals at the same levels. These findings suggest that the onset of this type of diabetes is largely influenced by genetic factors and/or the composition of gut...

People who avoid carbohydrates and eat more fat, even saturated fat, lose more body fat and have fewer cardiovascular risks than people who follow the low-fat diet that health authorities have favored for decades, a major new study shows. The findings are unlikely to be the final salvo in what has been a long and often contentious debate about what foods are best to eat for weight loss and overall health. The notion that dietary fat is harmful, particularly saturated fat, arose decades ago from comparisons of disease rates among large national populations. But more recent clinical studies in which...

Those with a diet low in protein likely to gorge on carbohydrates and fat Proportion of protein in Western diets has dropped - which could account for obesity levels Poeple must eat enough protein to satisfy appetites, scientists say Protein is essential for the healthy growth and repair of body tissues Over the past 60 years the proportion of protein in Western diets has dropped, and researchers suggest this could account for soaring levels of obesity.

Eating too much protein could be as dangerous as smoking for middle-aged people, a study has found. Research which tracked thousands of adults for nearly 20 years found that those who eat a diet rich in animal protein are four times more likely to die of cancer than someone with a low-protein diet. The risk is nearly as high as the danger of developing cancer from smoking 20 cigarettes each day. Previous studies have shown a link between cancer and red meat, but it is the first time research has measured the risk of death associated with regularly eating too...

You’re not imagining it: There really are differences between the way men and women diet, lose weight and respond to exercise. Some of the differences stem from biology; other differences are behavioral. But though many of these seem to give men a head start, they shouldn’t be taken to imply that guys have it easy. No matter who you are or where you’re starting, the road to your ideal weight is difficult at best, and confusing for most. But the information that researchers are unearthing about the differences in the way that men and women lose weight inspires hope that...

It sounds like science fiction, but it seems that bacteria within us - which outnumber our own cells about 100-fold - may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity.

The new study, which tracked more than 100,000 people from 17 countries over an average of more than three years, found that those who consumed fewer than 3,000 milligrams of sodium a day had a 27% higher risk of death or a serious event such as a heart attack or stroke in that period than those whose intake was estimated at 3,000 to 6,000 milligrams. Risk of death or other major events increased with intake above 6,000 milligrams. Last year, a report from the Institute of Medicine, which advises Congress on health issues, didn't find evidence that cutting sodium intake...

Facing Consumer Pressure, More Firms Are Jettisoning GMOs From Their Foods Two years ago, Ben & Jerry's Homemade Inc. initiated a plan to eliminate genetically modified ingredients from its ice cream, an effort to address a nascent consumer backlash and to fulfill its own environmental goals.This fall, nearly a year behind schedule, it expects to finish phase one, affecting its flavorful "chunks and swirls" like cookie dough and caramel. The only part left to convert: the milk that makes ice cream itself. Thanks to the complexities of sourcing milk deemed free of genetically modified material, that could take five to...

Scientists led by Dr David Fairlie from the University of Queensland, Australia, have found abnormal amounts of an inflammatory protein called PAR2 in the fat tissues of overweight and obese rats and humans. PAR2 is also increased on the surfaces of human immune cells by common fatty acids in the diet. When obese rats on a diet high in sugar and fat were given a new oral drug that binds to PAR2, the inflammation-causing properties of this protein were blocked, as were other effects of the high-fat and high-sugar diet, including obesity itself. "This important new finding links obesity and...

I mentioned two days ago the decision of schools to ban birthday cupcakes. Michelle Obama is essentially fighting with students to get them to change what they eat. But what is missing from this story is the proper context. The fact is that our bad eating habits are getting encouraged by taxpayer money. In fact, the government arguably changed our dietary habits to their present behavior. The Foundation for Economic Education came out with an article yesterday about dealing with “food deserts.”

Fossilized feces offer new evidence that Neanderthals ate both meat and plants. Chemical analysis confirmed the oldest-known ancient human fecal matter, according to a study published yesterday (June 25) in PLOS ONE. Previous isotope studies of bones suggested Neanderthals were primarily meat-eaters. Analyses of tartar from their teeth have indicated they may have also eaten plants, although some researchers noted that these plant remains could be traces from the stomach contents of herbivore prey. Stool, however, is "the perfect evidence because you’re sure it was consumed," study author Ainara Sistiaga from the University of La Laguna in Spain told BBC...

The American people have been given a lot of bad information about the link between saturated fat, cholesterol, and heart disease. This misinformation is slowly being corrected, and more research is being done in the area, but most medical organizations still recommend low-fat diets as “heart healthy.” We consume a lot less fats, and as a result, a lot more carbohydrates. (An unintended side effect: This diet has been blamed for the large increase in type 2 diabetes in our society over the last few decades.) I predict that in 10 years the medical profession will make yet another dietary...

TIME: The truth about fatTIME: Ending the war on fat The paradigm shift continues and the outdated fear of fat is on its way out faster and faster.You’d wish that some old-school fat phobics subscribed to the magazine. Unfortunately, I think this is hoping for too much, so I just emailed the cover to some of them.Some people will still spread low-fat margarine on their bread as long as they live, as an old habit. But most people will soon realize that not only does it taste bad, but...

A KITTEN has almost died after its owners fed it a strict vegan diet. The horrific case at a North Melbourne animal hospital has prompted a warning about the dangers of people "forcing ideologies" on their pets. Lort Smith Animal Hospital veterinarian Leanne Pinfold said the kitten was brought in this month by its owners, who were believed to be vegan. She said the kitten's diet of potatoes, rice milk and pasta had caused it to become critically ill. "It was extremely weak and collapsed when it came in. It was almost non-responsive," Dr Pinfold said. The kitten was given...

WHEN we began our Let’s Move! initiative four years ago, we set one simple but ambitious goal: to end the epidemic of childhood obesity in a generation so that kids born today will grow up healthy. To achieve this goal, we have adhered to one clear standard: what works. The initiatives we undertake are evidence-based, and we rely on the most current science. Research indicated that kids needed less sugar, salt and fat in their diets, so we revamped school lunch menus accordingly. When data showed that the lack of nearby grocery stores negatively affected people’s eating habits, we worked...

Be honest: That bacon, egg and cheese breakfast you scarfed down the other day was so delicious you’d love to have it for breakfast every morning. But like so many other health-conscious, weight-watching Americans, you just won’t allow yourself that indulgence. Instead, you opt for the usual low-fat, low-calorie and (oh-so-bland) oatmeal.
