Call for better regulation of caffeine diet pills

Caffeine supplements labelled as diet pills should be better regulated according to the Royal Pharmaceutical Society.

Caffeine supplements branded as diet pills should be better regulated according to the Royal Pharmaceutical Society

It follows the death of Chris Wilcock from Darwen, Lancashire, who died on the day that he took the tablets- which were the equivalent to 300 cups of coffee.

A coroner ruled his death in April was due to caffeine toxicity. At least four deaths in the UK have been linked to caffeine pills in the past year.

Neal Patel, from the Royal Pharmaceutical Society, said regulation was a “problem”.

“Unfortunately it does seem to fall between the Food Standards Agency and the medicine agencies and, in fact, it tends to be left to Trading Standards locally to pick out the products and see what’s in them.

“That doesn’t seem good enough given the number of deaths we’ve seen this year.”

Mr Patel added: “There is really flimsy evidence at best that caffeine can help reduce weight.”

Mr Wilcock, who was a pub landlord, died after taking a supplement known as T5, which contained caffeine equivalent to 300 cups of coffee.

T5 is a generic name for products that are often marketed as slimming aids. They are classified as food supplements instead of medicines, are legal and widely available.

Mr Wilcock’s fiancée Heather Thompson said she “tried to talk him out of” taking the pills.

“He just got told to take one a day and avoid alcohol with them – that was it. He didn’t get told of the side effects, he didn’t get told anything. It didn’t even say it on the actual bottle.”

The Royal Pharmaceutical Society said caffeine overdose could lead to symptoms including palpitations, high blood pressure, nausea and vomiting, convulsions and, in some cases, death.

The Medicines and Healthcare Products Regulatory Agency added: “There is a variety of different ingredients used in the various products with high levels of caffeine being one of the most popular ingredients.

“Such products are typically regarded to be food supplements rather than medicines. In instances where slimming products contain ingredients that are regarded to be medicinal the MHRA will investigate whether there is a breach of human medicines regulations and take action accordingly.”

Fasting may increase life span

Extreme fasting and calorie counting boosts lifespan in monkeys, according to new published research.

Fasting may increase life spanUntil now, the rationale for following an ultra-low calorie diet to ward off ageing has been based on experiments in worms and mice but now studies reported in Nature Communications found that primates also benefited from the regime.

Advocates of the Calorie Restriction (CR) diet claim that by severely restricting the number of calories they consume they will live longer, perhaps into their hundreds.

They cite a wealth of scientific evidence dating back more than 75 years.

Much of the research is based on experiments in animals such as mice and worms, with primate studies giving conflicting results. Now, a US team has published new evidence showing CR also shows benefits in primates.

“CR works to delay ageing in primate species,” Dr Rozalyn Anderson of the department of medicine at the University of Wisconsin-Madison, told BBC News. “Our study data is consistent with that.”

The study found CR boosted survival in a group of rhesus monkeys studied over the course of decades.

And she said conflicting findings, from a previous study at a different institute, might be due to flaws in the control group. But she said CR was a research tool not a lifestyle recommendation.

“The concept is to delve into the biology of ageing and try to understand what’s the basis for increased risk for diseases as you get older and with advanced age,” she said. “It would be very difficult to implement CR in a long term way in humans.”

A US study is currently looking at whether healthy humans live longer on less food.

The participants restrict calories by 25% over several years, existing mainly on a diet of vegetables, fruits (especially apples), and soups.

Sugar worse than salt claim health experts

Health experts claim avoiding sugar could be more important than avoiding salt when it comes to your healthy heart.

Sugar worse than salt claim health expertsScientists have clashed over claims that sugar may be worse for blood pressure and heart health than salt.

US experts say people need to place a greater focus on cutting sugar intake and suggest the benefits of lowering salt levels are “debatable.” Their arguments are published in the journal Open Heart.

But other researchers have said the claims are “disingenuous” and “scientifically unnecessary”. They maintain both need to be reduced.

Researchers from St Luke’s Mid America Heart Institute, and Montefiore Medical Centre in the USA reviewed a selection of evidence from basic science experiments, animal studies and human research.

They came to the conclusion that sugar – particularly fructose – may play a stronger role in high blood pressure and other cardiac conditions than salt.

And they say lowering salt consumption under certain levels may do more harm than good as the research team suggests attempts to reduce salt in processed food may drive people to eat more.

The US experts focus on a particular type of sugar – added fructose – often found in processed foods and sugary beverages.

But they say naturally occurring sugars in whole foods, for example those in fruit and vegetables, are not a cause for concern.

Data from the National Diet and Nutrition Survey in England suggests most adults and children eat more sugar than recommended.

The World Health Organization recommends sugars should make up less than 10% of total energy intake per day – this works out at about a maximum of 50g (1.7oz) of sugar for the average adult.

But the global health body recently acknowledged that halving this, to 5% of total energy intake per day, would have additional benefits.

Late night eating increases weight gain

Eating later in the evening might trigger weight gain say researchers who have been studying the effect in mice.

Late night eating increases weight gainEven when given the same amount of calories overall, mice that ate around the clock put on more fat.

Fasting for at least 12 hours appears to switch on important fat burning pathways in the body.

The US team told the journal Cell Metabolism they now plan human tests to see if the same is true in man.

During the study around 400 mice were fed diets high in sugar or fat or both, or normal diets and over different time periods.

Overall, mice that were only allowed to feed for nine or 12 hours gained less weight than mice that could eat the same amount food but at any time they wanted in a 24-hour period.

Even when the restricted feed time mice were allowed a blow out at weekends and could eat when they liked, they still gained less weight, suggesting that the diet can withstand some temporary interruptions, the researchers said.

And when obese mice who had been eating freely were moved to a restricted schedule they lost 5% of their body weight even though they were eating the same number of calories as before.

The researchers believe a key to controlling weight gain could be sticking to a consistent 12-hour fast every 24 hours.

In the experiments, fasting at night had beneficial effects on blood sugar and cholesterol and reversed the effects of diabetes in the mice.

Study leader Dr Satchidananda Panda, an associate professor at the Salk Institute in California, said that brown fat, which burns energy at a much higher rate is also activated by this approach.

Additional work in mice by another team showed that limiting eating to half the day also altered the balance of microbes in the gut, which experts say might be important.

UK’s five big killers

Five big killers – heart disease, stroke, cancer, lung and liver disease – account for more than 150,000 deaths a year among under-75s in England alone and the Department of Health estimates 30,000 of these are entirely avoidable.UK's five big killersCoronary Heart Disease is the biggest killer, causing almost 74,000 deaths each year in the UK- that’s about 200 people dying every day.

More than a quarter of the deaths occur in people who are younger than 75 and experts say the majority are preventable.

Smoking, being overweight and having high blood pressure are all risk factors.

About one in three adults in England and Scotland have high blood pressure and nearly half of them are not receiving treatment for the condition, says the British Heart Foundation.

Between April 2011 and March 2012 only 2% of those eligible in England actually had a health check. Out of nearly 16 million people eligible, about 425,000 were offered a check and 211,000 took up the offer.

England has one of the highest rates of asthma prevalence in the world. Figures from GP registers in 2008 suggested that about 6% of the English population has asthma.

And more than three million people in England are living with COPD. This lung disease kills about 23,000 people a year in the UK.

The most important cause of COPD is smoking, but about 15% of cases are work-related, triggered by exposure to fumes, chemicals and dusts at work.

Premature deaths from COPD in the UK was almost twice as high as the European average in 2008 and premature mortality for asthma was more than 1.5 times higher.

The disease is one of the most common causes of emergency admission to hospital and is expensive in terms of acute hospital care. It costs nearly 10 times more to treat severe COPD than the mild disease.

Strokes are the third leading cause of death in England each year and the leading cause of disability. More than 150,000 people have a stroke every year in the UK but, according to The Stroke Association, up to 10,000 of these could be prevented if more people were aware of the symptoms and sought out emergency treatment.

Symptoms can include facial weakness, speech problems and pins and needles down one side of the body.

The Health Secretary Mr Jeremy Hunt says a major challenge is getting all parts of the country to meet the performance levels of the best.

For example, if all patients suffering from a mini stroke (transient ischaemic attack or TIA) were treated as rapidly as those treated in the top 25% of hospitals, 540 strokes would be avoided each year, which in turn would save the NHS £4.5m a year.

Cancer has now become so common that today one in 30 people living in the UK either has cancer or is in remission. By 2030 it is estimated that three million people in England will have had some form of cancer.

The good news is that cancer survival rates are now improving in the UK.

More men are now surviving prostate and bowel cancer and women with breast cancer have a better outlook than ever before. But the UK still lags behind other European countries in terms of cancer survival.

Cancer Research UK says part of the problem is unhealthy lifestyles. It is estimated that about a third of cancers are caused by smoking, diet, alcohol and obesity.

And many cancers are detected too late. Although there are national screening programmes for certain cancers, like breast and cervical, public awareness of symptoms and the need to seek help early is still too low.

Another issue is access to treatment. Waiting times to see a doctor for speedy diagnosis and treatment have come down. But the provision of certain types of cancer investigations and treatments across the UK is variable and some groups of society, like the very old, can miss out.

Lastly, the Chief Medical Officer of England, Prof Dame Sally Davies, highlighted liver disease as an issue in her annual report.

It is the only major cause of mortality and morbidity that is on the increase in England while it is decreasing among European peers.

Between 2000 and 2009, deaths from chronic liver disease and cirrhosis in the under 65s in England increased by about 20% while they fell by the same amount in most EU countries. And all three major causes of liver disease – obesity, undiagnosed infection, and, increasingly, harmful drinking – are preventable.

More than a third of men and over a quarter of women regularly exceed the government recommended level of alcohol intake – three to four units of alcohol a day for men and two to three units for women.

The government in England is currently considering whether to set a minimum unit price for alcohol to deter problem drinking and cut alcohol-related illness.

Food allergies may be linked to chemicals in tap water

New research suggests that chemicals in tap water are linked to the huge rise in food allergies.Food allergies may be linked to chemicals in tap waterFood allergies have risen sharply over the past 20 years, with 1-2 per cent of adults and 4-6 per cent of children thought to be affected. The number of children admitted to hospital for food-related anaphylaxis (a life-threatening allergic reaction) has risen seven-fold since 1990 – but no one quite knows why.

The latest theory Food Allergies? Pesticides in Tap Water Might be to Blame, published in the Annals of Allergy, Asthma and Immunology, suggests that chemicals called dichlorophenols could be to blame.

US researchers who looked at food allergies in more than 2,000 people found that those with the highest levels of dichlorophenols in their urine had an 80 per cent higher risk of having a food allergy.

Their theory is that dichlorophenols, which they say are found in purified tap water and in pesticides and disinfectants, have anti-bacterial properties that could affect the microflora in the gut that are thought to protect against food allergies.

Dichlorophenols are also by-products of a common antibacterial and antifungal agent called triclosan (used in many consumer products, including toothpaste) and in the UK are more likely to be found in household cleaning products, kitchen utensils and containers and pesticide residues than in water.

Although little research has been done on UK exposure levels, the Chemicals Regulation Directorate says dichlorophenols “have not been identified as a cause of concern”.

The reason behind the rise in food and other allergies remains a mystery.

One well-known theory is the hygiene hypothesis – that as we become increasingly obsessed with cleanliness, our children are not exposed to the bugs that help the immune system develop properly. Another unproven theory is that the rise in allergies may be due to basic changes in Western diets, with processed foods becoming more common and fresh fruit and veg less so.

Some experts now think that government guidelines introduced in the Nineties may have contributed to the explosion in food allergies. “Parents were advised to avoid giving peanuts to young infants on the grounds that early consumption of potential allergens could affect underdeveloped immune systems, resulting in allergy – when the opposite seems to be the case,” says Prof Brostoff.

The guidelines were quietly withdrawn in 2009 after a large study the previous year showed that Jewish children living in the UK were almost 10 times more likely to develop a peanut allergy than those living in Israel, where peanut protein – often in the form of Bamba, a popular snack – is commonly given to infants in the first year of life.

Prof Brostoff says the best thing parents can do to reduce the risk of food allergy in their children is to gradually introduce potential allergens – not just peanuts, but cow’s milk, eggs and fish – at an early age.

“The lining of the gut membrane is the most powerful immune organ in the body,” he says. “The advice I always give is that it is better to introduce foods when the gut is more plastic and able to adapt. Giving a food early in a baby’s life can help make the gut more tolerant, and numerically this effect is more important than the presence in the environment of any chemicals.”

Smoking may worsen a hangover US research concludes

Smoking may worsen a hangover after drinking heavily US research concludes-  although the reason why is unclear.Smoking may worsen a hangover US research concludesResearchers asked 113 US students to keep a diary for eight weeks, recording their drinking and smoking habits and any hangover symptoms.

When they drank heavily- around six cans of beer an hour – those who also smoked suffered a worse hangover.

Addiction charities hope this study may motivate smokers to cut down over the festive season.

The study’s findings are reported in the Journal of Studies on Alcohol and Drugs.

One of the paper’s authors, Dr Damaris Rohsenow, from the Centre for Alcohol and Addiction Studies at Brown University said: “At the same number of drinks, people who smoke more that day are more likely to have a hangover and have more intense hangovers.”

“And smoking itself was linked to an increased risk of hangover compared with not smoking at all.  That raises the likelihood that there is some direct effect of tobacco smoking on hangovers.”

The students from a Midwestern university in the US reported on the number of drinks consumed, number of cigarettes smoked and their hangover symptoms – which included if they felt more tired than usual, had a headache, felt nauseated and had difficulty concentrating.

The researchers then estimated blood alcohol concentration (BAC) which helped control for differences between sexes as it took into account weight and the period over which the student drank alcohol.

After analysing the results, the researchers found that smoking more heavily the day before increased the presence and severity of hangover the next day – but only after a heavy drinking episode, estimated at a BAC of 110mg/dl or greater – the equivalent of around six cans of beer an hour.

The reasons why are unclear- but the study suggests it may down to the toxicological and pharmacological effects of nicotine on the nervous system.

Unhealthy lifestyles increases liver disease damage- CMO

High levels of drinking and obesity mean England is one of the few places in Europe seeing a major preventable disease getting worse warns the Chief Medical oOficer.Unhealthy lifestyles increases liver disease damage- CMOProf Dame Sally Davies highlighted the rise in liver-disease deaths in the under-65s – up 20% in a decade – in her annual report.

In comparison, most of the rest of Europe has seen rates fall.

She said urgent action was needed to discourage harmful lifestyles.

She said three of the major causes of liver disease – obesity, alcohol abuse and undiagnosed hepatitis infection – were all preventable.

But despite that, premature deaths from liver disease in the under-65s had jumped by a fifth since 2000 to 10 per 100,000 people.

Her study – the first volume of a Annual Report of the Chief Medical Officer – focused on a whole host of diseases from cancer to dementia.

But Dame Sally said it was the liver disease figures that most shocked her the most – and showed there needed to be investment in prevention, early diagnosis and effective treatment.

“I was struck by the data on liver disease particularly,” she said.

“This is the only major cause of preventative death that is on the increase in England that is generally falling in other comparable European nations.  We must act to change this.”

The report comes after the government said earlier this year it would look to introduce a minimum price for alcohol. A consultation is expected to start soon.

Just one daily fizzy drink linked to higher prostate cancer risk

Drinking just one fizzy drink a day could increase a man’s chance of developing prostate cancer by around 40 per cent, research suggests.Just one daily fizzy drink linked to higher prostate cancer riskMen who consumed 300ml of a sugary soft drink a day appeared to raise their odds of succumbing to faster growing forms of the disease, according to a 15 year study.

The sugar in the drinks is believed to release insulin, which feeds tumours.

The study, carried out by Swedish scientists and published in the American Journal of Clinical Nutrition, tracked the health of more than 8,000 men aged 45 to 73 for an average of 15 years.

All were in good health when the study began, and were asked about what they liked to eat and drink.

Those who drank more sugary drinks were more likely to have been diagnosed with prostate cancer by the end of the study.

Isabel Drake, a researcher at Lund University, said: “Among the men who drank a lot of soft drinks, we saw an increased risk of prostate cancer of around 40 per cent.”

Large amounts of rice, pasta, cakes, biscuits and sugary breakfast cereals were also linked with a less serious form of the disease.

Prostate cancer is the most common cancer in men and about 36,000 are diagnosed with the disease in the UK each year. It accounts for a quarter of all newly diagnosed cases of cancer in men but most cases develop in those aged 70 or older.

The scientists who carried out the study said that while genetics were more important in determining the likelihood of developing prostate cancer than was the case with many other cancers, diet did seem to be important.

More research was needed to confirm the link with fizzy drinks but there were already “plenty of reasons” to cut back on them, they said.
