Vegetarian, vegan and raw diets can be healthy — likely far healthier than the typical American diet. But to continue to call these diets "natural" for humans, in terms of evolution, is a bit of a stretch, according to two recent, independent studies.Eating meat and cooking food made us human, the studies suggest, enabling the brains of our prehuman ancestors to grow dramatically over a period of a few million years.Although this isn't the first such assertion from archaeologists and evolutionary biologists, the new studies demonstrate, respectively, that it would have been biologically implausible for humans to evolve such a large brain on a raw, vegan diet and that meat-eating was a crucial element of human evolution at least 1 million years before the dawn of humankind.Shhh, don't tell the gorillasAt the core of this research is the understanding that the modern human brain consumes 20 percent of the body's energy at rest, twice that of other primates.

Fast-food restaurants are serving healthier options, although only marginally so, according to a study published last week in the American Journal of Preventive Medicine.You may have known that changes were afoot in the fast-food restaurants most vilified by doctors for serving unhealthy fare. McDonald's, Burger King and others now offer salad, fruit, and skim milk. The new offerings, advertised prominently, would make one think that a trip to the local burger joint is suddenly heart-healthy, and waistline-friendly.Not quite, said Mary Hearst, director of public health at St. Catherine University in St. Paul, Minn., lead author on the report."The advertising of fast food restaurants has been emphasizing 'healthy' items, but there has been no data to support the claims," she told LiveScience.The study found that the nutritional quality improved only somewhat between 1997 and 2010. Based on the Healthy Eating Index, a measure of diet quality that assesses conformance to federal diet … [Read more...] about Do Fast-Food Restaurants Fall Short on Their Health Claims?
One of the strangest moments at the Black Hat USA security conference in Las Vegas this month has now become the subject of a federal lawsuit against the conference. In a filing to the United States District Court for the Southern District of New York (PDF), attorneys for the "emerging digital cryptography" firm Crown Sterling alleged that Black Hat USA had breached "its sponsorship agreement with Crown Sterling and the implied covenant of good faith and fair dealing arising therefrom." Crown Sterling goes on to accuse the conference organizers of "other wrongful conduct" connected to events surrounding the presentation of a paper by Crown Sterling CEO and founder Robert E. Grant. In addition to legally targeting the conference, Crown Sterling has also filed suit against 10 "Doe" defendants, who it claims orchestrated a disruption of the company's sponsored talk at Black Hat. Grant's presentation, entitled "Discovery of Quasi-Prime Numbers: What Does this Mean for Encryption," was … [Read more...] about Alleged “snake oil” crypto company sues over boos at Black Hat [Updated]
