Q: Called the PURE (Prospective Urban Rural Epidemiology) study, this was a very large observational study looking at the link between fat and carbohydrate consumption and longevity in 18 countries across 5 continents. Running for 7 years and involving over 135,000 people, this was a very big study so its conclusions are right to take notice of. The key finding from the work that attracted the most media attention was that a high carbohydrate diet was linked with a higher risk of earlier mortality, whereas total fat and individual types of fat were related to a lower risk of earlier mortality. Digging deeper into the study, the research team found that global diets consisted of 61 percent energy coming from carbohydrates and 24 percent energy from fats. And while those in the highest carbohydrate consumption group (a whopping 77 percent of energy) had a higher risk of earlier death, it wasn't cardiovascular disease they were dying from. What those other causes of death were exactly is unclear. Perhaps getting hit by a car running for a Mars Bar was one of them as a recent commenter on my Facebook page theorised. A paradigm shift? Not quite Does this study turn on its head 'everything we knew about nutrition?' Not quite. And here's why. Before the PURE study, there were many studies showing the opposite link between carbohydrates and longevity. So, when a conflicting study comes along, this grabs the media spotlight for the day. Here is just one example a major systematic review and meta-analysis from 2013 involving 17 individual studies and over 242,000 people showing a higher risk of earlier mortality as carbohydrate intake decreased. And this is the problem at times with observational research in that two studies can give polar opposite results so the findings of the PURE study should be seen through this filter. I'm not going to pick apart the PURE study for its flaws. Such issues are consistent across all observational studies no matter if the conclusions support consensus views or not. What is of value to... Question: Why was the attention of the media grabbed by the PURE study? === The answer to the above question is
Answer: it was conflicting with a previous study that showed the opposite link of carbohydrates and longevity

SEOUL South Korea is looking into developing and financing economic projects with North Korea that could take effect if a nuclear deal is reached with the United States. South Korean Finance Minister Kim Dong-yeon said on Wednesday the government was "internally carrying out preparations" to organize, finance and implement possible inter-Korea projects. But he also emphasized that Seoul would first seek support from the international community for any North Korean development projects, and would only proceed if the U.S. -North Korea summit, expected to be held in late May or June, produces a joint denuclearization agreement. North Korea is under tough sanctions imposed by the U.N. Security Council for its nuclear weapons and missiles tests, including accelerated efforts in the last two years to develop a long-range nuclear missile that could potentially target the U.S. mainland. The international sanctions ban an estimated 90 percent of the country's external trade. Seeking sanctions relief is considered a key motivating factor in North Korean leader Kim Jong Un's diplomatic pivot this year to suspend further provocative missile and nuclear tests, and to engage in talks to dismantle his nuclear arsenal. But easing sanctions would make it more difficult to enforce the North's denuclearization promises. "Once the sanctions are lifted, North Korea will gain autonomy over its trade, and considering its low labor costs and skilled workforce, I think the North Korean economy would gain power again," said Shin Beom-chul, the director of Center for Security and Unification at the Asan Institute for Policy Studies in Seoul. U.S. President Donald Trump has insisted he will keep sanctions in place until North Korea completely dismantles its nuclear program. South Korea, however, is considering a range of economic incentives to encourage Kim to follow through on a nuclear deal with Trump. But these investments are prohibited by the U.N. sanctions and would require a Security Council exemption to proceed. At the recent...

- Never Now, answer this question: Angela Hammerly dedicated her life to becoming District Attorney. At 42, she had never been married, or even seriously dated. All she could think about, night and day, was her ultimate goal. And her dream finally came true, thanks to the death of 74-year-old Porter Strickley. She could not deny that she had learned the job well, working for that old pain-in-the-butt. He was 57 when she interviewed for the position of Assistant District Attorney. At the time, she thought he was 70. Two months ago, she had become the District Attorney. She loved seeing her name on the door. And she felt a rush of adrenaline every time a judge referred to her as 'The District Attorney' in open court. The D.A.'s office would be better than ever--now that she was running the show. There was a soft knock, and Andrea Newly opened the door just enough to peek in. "Come in, Andrea." Angela sometimes wondered if she had made a mistake two weeks ago when she hired this timid young lady as her assistant. Angela had been impressed with her resume. But in person, Andrea was quiet, and seemed to be rather intimidated by Angela. But Andrea was enthralled with every word Angela spoke. And the new D.A. couldn't resist the prospect of being god to her assistant. She had hired her on the spot, even though she knew Andrea would stress her patience. But Angela was confident the 25-year-old could be molded into her mentor's image. And thereby, become a powerful force for justice in the D.A.'s office. Andrea took a chair across from the D.A. The furniture in the District Attorney's office was similar to that found in most old government offices-largely unchanged since the 1950s. Yet the hardwood chairs and desks were of such good quality that an exact replacement would be cost prohibitive in today's market. Angela planned to upsize her diminutive desk as soon as possible, even if the money came out of her own pocket. Question: When did Angela hired Andrea to be her assistant? === The answer to the above question is
