Ques:Dietary supplements are big business, with around half of the Australian population using at least one type per year; most commonly a multivitamin and mineral pill. Many people take supplements as a form of dietary insurance in case they are not meeting their nutrient needs from foods alone. Others take them as a form of health insurance to protect against certain diseases. Some just take them out of habit. Supplements do have a role to play in some situations. People with a diagnosed deficiency, those with malabsorption conditions, women planning pregnancy, and people with very poor diets all can benefit from specific nutrient supplementation. But what about the benefit of supplements across the broad population? The mantra of most health professionals, which is even etched on the label of many supplements, is that supplements may only be of assistance if dietary sources are lacking. To see if this is supported by solid evidence, a systematic review of 63 clinical trials involving some form of supplementation in non-pregnant adults was carried out by a team of medical researchers. The clinical trials were broad in their nature with many nutrients studied including vitamins A, B6, B12, C, D and E; folic acid; calcium; selenium, omega-3 fatty acids; ginkgo biloba; glucosamine; saw palmetto; and milk thistle. All of the studies were randomised controlled trials and evaluated a range of health outcomes including risk of heart disease, cancer, diabetes, bone fractures, cognitive function and all-cause mortality. From the 63 studies, no benefit was seen in 45 studies with 10 of these showing a trend towards harm and just two showing a trend towards a benefit. Of the remaining studies, four showed harm with a greater risk of cancer with beta-carotene and a higher risk of fractures with a once-yearly dose of vitamin D. One study showed a lower risk of cancer with selenium supplementation, but this was not validated in much larger trials. Twelve studies showed a benefit and these mostly involved vitamin D... What effects did the scientists study? - Positive effects - not enough information - Dietary effects - Negative effects

Ans:Positive effects

Ques:It's always interesting to read back on why people do things, especially people who end up making a career or a fortune out of the seemingly benign choices they make. Thelma Schoonmaker, the film editor whom my previous post was about was one of those people; she got into editing after seeing an ad in the New York Times. I'm in no way suggesting I'm going to make a fortune, nor that I'm a Thelma Schoonmaker in the making, but I certainly do make a lot of benign choices. Art blogging, for me, was one of those benign choices. I made the decision to start an art blog very randomly, so randomly I'm not even sure where the idea came from. At the time I had been studying a bachelor of psychology for about two years and found myself interested in the subject, but underwhelmed with the lack of creative ideas and media I was being exposed to. I'd always been interested in art and most creative mediums, often recording music or taking photographs on the side. But the pages and pages of white and black scientific journal articles must have got to me, because I found myself yearning for splashes of colour, moving imagery, challenging concepts and undefinable ideas. The next thing I knew I had started an art blog aptly titled: Artistic Expansion and I began spending hours a day searching through the internet for content, often finding my best pieces in the most random places, often not even defined intentionally as 'art'. Over the last two years I must have blogged hundreds of multi-coloured, multi-textured and multi-layered images, accumulated over 2000 followers and consumed more art than I ever had in my entire life. I find it interesting not because of it's success, but because before I started my art blog, I really had no idea how much I did or could love art and once I had made my art blog I couldn't imagine how I ever functioned without it. The author probably believes that: - art is a boring hobby - not enough information - art is a terrible hobby - art is a refreshing hobby

Ans:art is a refreshing hobby

Ques:Christopher Warm had a sedentary job. On his keyboard he typed various letters and numbers, which would become computer programs. In his company he was known as Office Desk, because when he was working he always sat behind his well-used piece of conference table standing in a hard to notice corner in the software specialists' room. Christopher wasn't a wide person, and so his piece of conference table didn't have to be too big either, which also practically solved office space problems in the 0-1 Computer firm. It was Warm's secret that the majority of his time outside of the company, he also spent behind a desk. On his keyboard he typed various letters and numbers, which would become computer programs for the 0-1 Computer Associates company. While the Man Called Office Desk (MCOD, or simply Cod in an alternative version) was writing an intuitive program for the management of empty office desk space in software companies, a thing that nobody had ever expected to happen happened. Warm became fused with the chair. The staff at 0-1 Computer were disappointed, they had expected Cod to fuse with a desk. It would have been much more entertaining to watch, you could have laughed at him a little, and the nickname, given to him by the programmers' boss would have gotten a whole new meaning. And right now, there wasn't even much to talk about during cigarette breaks. Warm did not hide the fact he would have preferred to fuse with a mouse, or a mouse pad. Right now, all he could do was to pretend he totally ignored the fact he was physically stuck to a chair. And he was doing just fine until it was time to go to his second shift at 1-0 Computer Associates, where he had been working on a program for the management of empty space in staff lockers in telecommunications companies. What happened after Christopher fused? - not enough information - He pretended to ignore it - He joked about it - He started working on a new program

Ans:
He pretended to ignore it
