Scientists from around the world examined whether supplements marketed are good for brain health, particularly in those aged over 50. Despite the claims of some supplements that they could improve cognitive （认知的）skills, no clear evidence was found to back this up.
The report said, "For the handful that have been researched, several well-designed studies of supplements for brain health found no benefit in people with normal nutrient levels. It's unclear whether people who lack nutrition can benefit their brains by taking a supplement. The pills failed to protect against dementia （痴呆）and did not slow the process or improve the symptoms of the disease and the report said that a healthy diet rich in fruit and vegetables, being physically active and getting sufficient sleep were linked to better brain function. ”
The value of the food supplement market in Britain is expected to reach more than £1 billion by 2012 and supplements sold on the high street for brain performance cost up to £26 for 60 pills. And Caroline Abrahams, the charity director at Age UK said that people were better off spending money to improve diets.
The report did find evidence suggesting that supplements could benefit people diagnosed with lacking vitamin. It added that these should only be taken if advised by a doctor because some supplements could interact with medicines or contain high levels of nutrients, which could be deadly. Supplements were not strictly controlled in the way that medicines were and may not contain high-quality ingredients or what was on the label, the report said.
The Health Food Manufacturers' Association, which represents the British supplement industry, said that the report was based on the American market. In Britain products could only make claims approved by the European Food Safety Authority, such as the zinc （锌）contributed to normal cognitive functions, a spokesman said.

One in five women and one in eight men are becoming more tired and less productive, according to a new Australian study on mobile phone use.
Led by the Queensland University of Technology in Australia, researchers surveyed 709 mobile phone users across the country aged 18 to 83 and asked them a series of questions based on a similar study 13 years ago. Identifying a phenomenon "technoference (科技干扰)", researchers discovered a significant increase in people blaming their devices for losing sleep, becoming less productive and even getting more aches and pains".
According to the study's lead author Dr Oscar, the issue is so bad that 24 percent of women and 15 percent of men are now considered to be " problematic mobile phone users". "When we talk about technoference, we're referring to the everyday intrusions (侵入)and interruptions that people experience due to mobile phones and their usage," he said. "Our survey found technoference had increased among men and women. For example, self-reports relating to the loss of sleep and productivity showed that these negative outcomes had significantly increased during the last 13 years. This finding suggests that mobile phones are potentially increasingly affecting aspects of daytime functioning due to lack of sleep. "
Compared to a 2005 study, "technoference" issues for 18 to 24-year-old experienced a surprising 40. 9 percent rise, while those aged 25 to 29 also recorded a dramatic increase of 23. 5 percent.
Oscar said that with the number of smartphone users around the world expected to surpass 2. 5 billion before the end of this year, the problem of "technoference" could get even worse. "The speed and depth of smartphone take-up makes our population particularly vulnerable to some of the negative consequences of high mobile phone use." he said. "Rapid technological innovations have led to dramatic changes in today's mobile phone technology, which can improve the quality of life for phone users but also result in some negative outcomes. "

It's a small business 1 started, and everyone who enjoy, working here comes into the studio in free time, so they can be home with their family, cats, dogs at prime times.
I first fell in love with candles on visits to my grandmother Feme's house in Lincoln. At night, candlelight flashed off the book-lined walls. During the day, she'd take me to a cafe in the historic Haymarket district and we'd drink tea out of china cups.
I poured my first candle at the age of 14, using the candle-making tool that Feme had given me. I gave the finished product to my grandmother for Christmas. She loved that candle I'd made for her. That first candle was imperfect. Beautifully imperfect・
Then in 2014. life took a dark turn for my grandmother. The breast cancer took away her life. I found myself thinking about the candle-making tool she had given me as a 14-year-old kid and the joy it had brought me. I began pouring candles again, making them for friends. Because of kids' health. I'd become especially interested in natural products. I used locally sourced soy wax. Was there a way I could make candles for people beyond my group of friends? And so, Christmas of that year, Wax Buffalo was launched. Little by little, the business grew as we found more people who wanted our candles. Now our candles are sold in more than 60 shops across the country.
Isn't life wonderful? Indeed, it is beautifully imperfect. But it hasn't turned out at all how I'd have predicted. I think that's what Ferne wanted me to understand. To trust the light of hope, to enjoy fun in its light, to know that it can transform a person from within.
