Removing sugar from diet for just nine days can have 'dramatic results,' new study claims
Giving up sugar for just nine days can dramatically improve people's health, a new study claims.
The study, published by the journal Obesity, substituted the sugar intake of 43 obese children with starch and claims to have demonstrated sugar is dangerous not because of its calories but because of the strain it places on the body's metabolism.
Study author Robert Lustig, paediatric endocrinologist at UCSF Benioff Children's Hospital in San Francisco, said his research found the children's cholesterol improved and their insulin levels dropped.
"Everything got better," Dr Lustig claimed. "These findings support the idea that it is essential for parents to evaluate sugar intake and to be mindful of the health effects of what their children are consuming."
His findings contest prevalent thinking, supported by multi-national corporations, that claims obesity - and related diseases - are not the result of sugar but of high calorie intake.
Dr Lustig says his study was careful to avoid this: researchers ensured the children participating in the study maintained the same weight and were encouraged to eat more if researchers saw their weight falling.
He claimed as a result the children, aged between eight and 18, began "responding to their satiety cues" and told researchers they were "overwhelming them with food."
"Sugar calories are the worst, because they turn to fat in the liver, driving insulin resistance, and driving risk for diabetes, heart, and liver disease.
"This has enormous implications for the food industry, chronic disease, and health care costs," he told The Daily Telegraph.
Senior paper author Jean-Marc Schwarz claimed he had never seen results "as striking or significant".
"After only nine days of fructose restriction, the results are dramatic and consistent from subject to subject."
His study follows a report last week that called for a tax on sugar, rejected by David Cameron. The Prime Minister said other measures - such as tighter controls on advertising - could help to curtail childhood obesity.
Writing in the Guardian, Dr Lustig claims the PM is wrong to think taxing sugar is about obesity - "It's about type 2 diabetes."
Approximately 5.4 per cent of Britons suffer from diabetes, with the disease and related complications costing the NHS an estimated £14billion every year.
However, Dr Lustig did caution his study "does not prove that sugar is the sole cause of metabolic disease," but that "it clearly demonstrates it is a modifiable one."

Re: Health Bulletin
High speed cameras catch the physics of sneezing
Why is it absolutely essential to cover your mouth the next time you sneeze? New high-speed videos captured by MIT researchers show that as a person sneezes, they launch a sheet of fluid that balloons, then breaks apart in long threads that finally disperses as a spray of droplets. In other words, the droplets may survive for much longer distances, thus increasing the chances of infecting others.
This complex pattern runs counter to what most people expect, which is that a sneeze produces a simple and uniform spray of droplets.
""What we saw was surprising in many ways,"" says Lydia Bourouiba, professor and head of the Fluid Dynamics of Disease Transmission Laboratory at MIT. ""We expected to see droplets coming out fully formed from the respiratory tract. It turns out that's not the case at all. And this gives us a good baseline to expand our mechanistic understanding of violent expirations.""
Using two high-speed cameras, the researchers recorded more than 100 sneezes from healthy human subjects and captured the fraction of a second during which fluid is expelled from the mouth and flung through the air. Almost every sneeze produced the same paint-like pattern of fluid fragmentation, with slight variations: The more elastic the fluid, or saliva, the longer the fluid traveled before breaking into droplets.
Bourouiba says understanding how sneezing disperses droplets can help researchers map the spread of infections through the environment, as well as identify individuals who may be ""super spreaders."" The findings are published in the journal Experimental Fluids.
The current work builds off research Bourouiba and John Bush reported in 2014, in which they showed that coughs and sneezes produce clouds of gas that carry infectious droplets up to 200 times farther than they would have traveled if they were simply disconnected drops.
This time around, Bourouiba focused the high-speed imaging on the distribution of droplets produced from sneezing-a more violent expulsion, compared with coughs.
For their experiments, the researchers positioned each of three human subjects against a black backdrop and other settings, and set up two high-speed monochrome cameras, focused just in front of a subject's mouth. To induce sneezing, they ""tickled"" the subjects' noses and then recorded as much of the sneeze event as they could-a short window of under 200 milliseconds.
After analyzing more than 100 sneezes, the researchers identified a common pattern: Immediately after exiting the mouth, the exhaled fluid can form a wide sheet that balloons with the simultaneous expelling of air. As it travels through the air, the balloon bursts into thin filaments that eventually separate into individual droplets of various sizes that ultimately fall to the ground or remain suspended in the turbulent cloud.
The team also observed an interesting variation. For subjects with more elastic saliva, the expelled fluid tended to stay in filament form longer, forming beads along the filaments that eventually slid off as droplets.

Learning second language can delay ageing of the brain, say scientists
earning a second language can boost thinking skills, improve mental agility and delay the ageing of the brain, according to scientists who believe that speaking minority languages should be positively encouraged in schools and universities.
Studies have found that children and adults who learn or speak another language benefit from the extra effort it takes to handle two sets of vocabularies and rules of grammar.
"Fewer parents speak minority languages to their children because of the perceived lack of usefulness. Many people still think that a minority language makes children confused and puts them at a disadvantage at school," said Antonella Sorace of the University of Edinburgh.
"These feelings clash with much research on bilingualism, which shows instead that when there are differences between monolingual and bilingual children, these are almost invariably in favour of blinguals," Dr Sorace said.
"Bilingual children tend to have enhanced language abilities, a better understanding of others' point of view, and more mental flexibility in dealing with complex situations," she told the American Association for the Advancement of Science in Washington.
Many of the same improvements are seen in adults who speak two languages, or are learning a second language. A study of retired people doing an intensive language course of five hours a day on the Isle of Skye to learn Gaelic found improvements in other mental abilities.

"They didn't know a word of Gaelic, so we tested them beforehand and after a week of a very intensive course. And sure enough, when we compared them with other active retired people who were doing a course on something else, we found in those who were doing a language course, the brain responds," Dr Sorace said.
Other studies have shown that certain types of dementia seen in the elderly appear to show symptoms on average about four or five years later in bilingual people compared with people who speak only one language, she said. One theory is that elderly bilinguals have greater "cognitive reserves" which delay the onset of ageing in the brain.
Dr Sorace said that learning a second language should be made compulsory again in schools and even universities. "Languages should be a requirement for any kind of degree ... whether people are doing classics or literature or a science degree," she said.

Speech disorder can lead to brain disease
Apraxia, a problem with speech programming, can lead to neurodegenerative disease - a condition that affects neurons in the human brain, a study says.
Apraxia of speech can evolve into a neurologic disorder, causing difficulty with eye movement, using the limbs, walking and falling that worsens as time passes.
It may start with a simple word one can't pronounce and may lead to stage in six years that, they are in a diapers, can't speak, can't walk and are drooling, said the researchers from Mayo Clinic in Minnesota, US.
Some patients eventually become mute from primary progressive apraxia of speech.

The symptoms exhibited by people with apraxia of speech include slow speech rate, inconsistent mistakes, such as saying a word or sound correctly sometimes and not others, impaired rhythm of speech, groping of the mouth to make sounds, better automatic speech, such as greetings, compared with purposeful speech, the study elicited.
"Because patients and even many medical professionals don't recognise apraxia of speech, treatment typically is sought in later stages of the disease," said Keith Josephs, a neurologist from Mayo Clinic.
While speech therapy does not reverse or halt the progression of apraxia, it can develop compensations for producing better sounds. People with apraxia of speech also can use computers or texting for alternate means of communicating, the researchers said.
Speech is a complex brain-body achievement, these researchers note. It first requires selection of appropriate words, organising them into a coherent message. This message activates 100 muscles between the lungs and lips to produce at least 14 distinct sounds per second that can be comprehended by a listener.
The study was presented at the American Association for the Advancement of Science (AAAS) annual meeting in the US last weekend.

How genes may influence ageing decoded
Scientists have found that a hormone linked to the ageing process is controlled by genetics, a finding that suggests a new pathway by which genes regulate ageing and age-related diseases.
Previous studies have found that blood levels of the hormone GDF11 decrease over time.
Restoration of GDF11 reverses cardiovascular ageing in old mice and leads to muscle and brain rejuvenation, a discovery that was listed as one of the top 10 breakthroughs in science in 2014.
Scientists at the University of Georgia in US have now discovered that levels of this hormone are determined by genetics, representing another potential mechanism by which ageing is encoded in the genome.
"Finding that GDF11 levels are under genetic control is of significant interest. Since it is under genetic control, we can find the genes responsible for GDF11 levels and its changes with age," said the study's senior author Rob Pazdro, an assistant professor at University of Georgia.
The study confirmed results from previous experiments showing that GDF11 levels decrease over time and also showed that most of the depletion occurs by middle age.
In addition, the study examined the relationship between GDF11 levels and markers of ageing such as lifespan in 22 genetically diverse inbred mice strains.
The strains with the highest GDF11 levels tended to live the longest, the researchers said.
Using gene mapping, Pazdro's team then identified seven candidate genes that may determine blood GDF11 concentrations at middle age, demonstrating for the first time that GDF11 levels are highly heritable.
"Essentially, we found a missing piece of the ageing/genetics puzzle," Pazdro said.
"Very generally, we've made an important step toward learning about ageing and why we age and what are the pathways that drive it," Pazdro said.
The study was published in the the Journals of Gerontology Series A Biological Sciences and Medical Sciences.

Homeopathy found to be effective for 0 out of 68 illnesses
A leading scientist has declared homeopathy a "therapeutic dead-end" after a systematic review concluded the controversial treatment was no more effective than placebo drugs.
Professor Paul Glasziou, a leading academic in evidence based medicine at Bond University, was the chair of a working party by the National Health and Medical Research Council which was tasked with reviewing the evidence of 176 trials of homeopathy to establish if the treatment is valid.
A total of 57 systematic reviews, containing the 176 individual studies, focused on 68 different health conditions - and found there to be no evidence homeopathy was more effective than placebo on any.
Homeopathy is an alternative medicine based on the idea of diluting a substance in water. According to the NHS: "Practitioners believe that the more a substance is diluted in this way, the greater its power to treat symptoms. Many homeopathic remedies consist of substances that have been diluted many times in water until there is none or almost none of the original substance left."
The review found "no discernible convincing effects beyond placebo" and concluded "there was no reliable evidence from research in humans that homeopathy was effective for treating the range of health conditions considered".
Writing in a blog for the British Medical Journal, Professor Glasziou states: "As chair of the working party which produced the report I was simply relieved that the arduous journey of sifting and synthesising the evidence was at an end. I had begun the journey with an 'I don't know attitude', curious about whether this unlikely treatment could ever work... but I lost interest after looking at the 57 systematic reviews which contained 176 individual studies and finding no discernible convincing effects beyond placebo."
He continues: "I can well understand why Samuel Hahnemann- the founder of homeopathy- was dissatisfied with the state of 18th century medicine's practices, such as blood-letting and purging and tried to find a better alternative.
"But I would guess he would be disappointed by the collective failure of homeopathy to carry on his innovative investigations, but instead continue to pursue a therapeutic dead-end."
In the UK, two NHS hospitals provide homeopathy, as well as a number of GP practices.

Re: Health Bulletin
Absurd. Nobody knows, how they dare to come to such a conclusion and also publish their results over a Science in existence for more than 200 years and found effective through out the world.
No one can refute the fact, that many western countries including US, have Hospitals practicing Homoeopathy. Should this Professor means to say that his fellow Vice Chancellors, Professors and Heads of Institutions including the Public who by their experience agreed and supported this Science are all fools. If he means that, he should visit such Institutions / Universities and sit with Scholars of his Standard and prove his findings and make them accept his findings.
In India too a no. of Medical universities considered and accepted Homoeopathy as a course of study, for more than 50 years now. It has been proved beyond doubt, that in many cases where allopathy cannot have a break through, Homoeopathy has done that.
Highly a questionable research and the veracity of findings needs to be authenticated by someone from Homoeopathy fraternity similar to the calibre of Prof Paul, without which this findings may not have any merits.
A research scholar of high standard, should not make a mockery of a proven Science.
