Eating chips in pregnancy can cause underweight babies

Eating chips during pregnancy can lead to significant health problems for new born babies new research suggests.Eating chips in pregnancy can cause underweight babiesConsuming a vast quantity of chips, crisps and biscuits during pregnancy can lead to babies having a lower than average birth weight, the study found.

Mothers-to-be who have a high intake of acrylamide – which is found in commonly consumed foods and coffee – are also more likely to have a baby which has a smaller head circumference.

The size of a child’s head has been associated with delayed neurodevelopment while lower birth weights have been associated with adverse health effects in early life and as children grow up.

Babies born to mothers with a high dietary intake of acrylamide were found to be up to 132 grams lighter than babies born to mothers who had a low intake, researchers said.

The mean birth weight among children who were exposed to the highest levels of acrylamide compared with children in the lowest was around 100 grams, the authors said.

The effect caused by acrylamide is comparable to lower birth weights caused by maternal smoking, they said.

The infant’s heads were also up to 0.33 centimetres smaller, they found.

Acrylamide is a chemical which is produced naturally in food as a result of cooking starch-rich food at high temperatures, such as when baking or frying. It has been found in a wide range of home-cooked and processed foods including crisps, chips, bread and coffee.

“The potential public-health implications of our findings are substantial,” the authors said.

“Reduced birth weight is a risk factor for numerous adverse health effects early in life, and has been associated with multiple adverse outcomes later in life such as reduced stature, increased incidence of cardiovascular disease, type 2 diabetes mellitus, and osteoporosis.”

They added: “These findings provide evidence supporting the need for changes in food production and for providing clear public health advice to pregnant women to reduce their dietary intake of foods that may contain high concentrations of acrylamide.”

Researchers examined the diets of 1,100 pregnant women between 2006 and 2010 in Denmark, England, Greece, Norway and Spain.

The study A comparative analysis of dietary intakes during pregnancy in Europe , led by the Centre for Research in Environmental Epidemiology (CREAL) in Barcelona, involved 20 research centres across Europe including the Born in Bradford research programme.

Dr Laura Hardie, reader in molecular epidemiology at the University of Leeds, said: “186 women from the Born in Bradford study took part in this major European research programme. We found that their babies had the highest levels of acrylamide out of all of the five centres, almost twice the level of the Danish babies.

“When we investigated their diet it was clear that the largest source of dietary acrylamide is from chips.”

CREAL researcher and lead author Dr Marie Pedersen, added: “The public-health implications of the findings in this study are substantial.

“Reduced birth weight, in particular low birth weight, has been shown to be related to numerous adverse health effects early or later in life such as cardiovascular disease and diabetes. Furthermore, reduced birth head circumference has been associated with delayed neurodevelopment.”

Does a high fat diet damage your brain?

Eating a high fat diet can impair the function of the part of the brain that controls appetite and energy expenditure which in turn dictates our weight.Does a high fat diet damage your brain?That is the finding presented at the British Science Festival by scientists at the University of Aberdeen Rowett Institute for Nutrition and Health.

This may help explain why overweight people struggle to lose weight and then struggle to maintain their weight loss.

Researchers fed mice a diet high in saturated fat and sugar over 16 weeks – where 60% of their energy came from saturated fat – and compared them with mice fed a normal diet over the same period.

Using techniques such as transcriptomics and proteomics, scientists then studied genes and proteins in the hypothalamus of their brain – the part that regulates eating and energy expenditure.

They found that mice fed a high fat diet had changes to genes and proteins indicative of damage in the hypothalamus and that these changes occurred very rapidly – within weeks.

Dr Lynda Williams, Obesity and Metabolic Health Group Leader, at the Rowett, said: “The hypothalamus is a small area at the base of the brain containing neurones that control the amount of food we eat and the energy we expend.

“However this control breaks down in obesity – the system appears not to work – and we don’t really know why this happens. In our study we found that genes and proteins changed in response to a high fat diet and that these changes are normally associated with damage in the brain, indicating that damage had occurred in the hypothalamus in mice that ate a diet high in saturated fat.

“We instinctively know that eating a diet high in saturated fat and sugar will lead to overweight and obesity. Our results indicate that a high fat diet can damage the areas of the brain that control energy balance and perpetuate the development of obesity. High fat and high sugar foods are energy dense foods which are highly palatable and they are very easy to overeat.”

“Our findings may also explain why some overweight people find it difficult to diet and why weight loss after dieting is so difficult to maintain. We now plan to carry out further studies that will look at whether these effects are reversible.”

Dieting- it’s all in the timing

Sticking to strict meal times every day is good for the metabolism and helps the body burn off fat according to new research.Dieting- it's all in the timingPeople who snack on healthy food may consume only a small amount of fat- however their haphazard eating patterns mean they can put on weight, a new reserach study suggests.

In contrast, sticking to strict meal times is good for the metabolism and helps the body burn off fat- allowing a more liberal choice of food.

The findings indicate that adopting a fixed timetable for meals could be a more effective method of dieting than trying to cut out fatty foods and might help prevent obesity, researchers said.

Previous studies have shown that both a high fat diet and eating patterns that disrupt the natural body clock can interfere with our metabolism and raise the risk of obesity.

Scientists from the Hebrew University of Jerusalem tested the effects of timing and fat intake on four groups of mice over an 18-week period to determine whether careful scheduling of meals could lower the effects of a high-fat diet.

Half were given a high-fat diet that would normally be expected to make them obese. Of these, a quarter were fed at the same time each day and another quarter could eat as much as they liked, whenever they liked.

The other half were fed a diet that was lower in fat. Again, one quarter had a fixed feeding time, the other had not.

All four of the groups gained weight over the course of the trial, with the group that ate a high-fat diet at irregular intervals unsurprisingly gaining the most weight, while those on a low-fat, scheduled diet gained the least.

But more surprisingly, the mice that had been fed a high-fat diet at regular intervals finished the trial in a better condition than those that ate low fat foods whenever they wanted, despite both groups consuming the same number of calories overall.

The mice in the scheduled, high fat group had 12 per cent lower body weight, 21 per cent lower cholesterol and 1.4 times higher sensitivity to insulin than the unscheduled, low-fat group.

The diet also changed their metabolism so that they burnt off the fats they ingested to produce energy in between meal times, rather than storing the fat in their bodies.

The study was published in the Journal of the Federation of American Societies for Experimental Biology.

New York bans large sugary drinks

New York City’s health board has passed a law prohibiting the sale of sugary drinks larger than 16 ounces- an act which Mayor Michael Bloomberg says will save lives by reducing obesity.New York bans large sugary drinksNew York City passed the first US ban of oversized sugary drinks in its latest controversial step to reduce obesity and its deadly complications in a nation with a weight problem.

The mayoral appointed city health board outlawed sugary drinks larger than 16 ounces (one pint) nearly everywhere they are sold, except grocery and convenience stores.

Violators of the ban, which does not include diet sodas, face a $200 (£125) fine.

At a news conference at City Hall, Bloomberg heralded the measure’s passage as “the single biggest step any city I think has ever taken to curb obesity.

“We believe that it will help save lives,” he added.

About one third of Americans are obese, and about 10 per cent of the nation’s healthcare bill is tied to obesity related diseases, such as Type 2 diabetes, heart disease and hypertension, according to the Organization for Economic Co-operation and Development .

Supermarkets’ luxury ranges contain twice as much fat, salt and sugar as budget versions

Supermarkets’ ‘luxury’ ranges of ready meals can contain more than twice as much fat and salt than the budget, ‘no-frills’ versions, according to a new academic research.Supermarkets' luxury ranges contain twice as much fat, salt and sugar as budget versionsGlasgow University academics said some of the meals should be labelled “damaging” on their packaging after discovering that they contained “shocking” levels of saturated fat, the major cause of heart disease.

After analysing a range of convenience foods produced by five of Britain’s largest supermarket chains, they found the ‘finest’ ranges of ready meals regularly contained up to 100 per cent of fat that should be consumed by an adult in an entire day.

The study, published in Trends in Food Science & Technology, also discovered one serving of a luxury meal contains up to half the guideline daily amount (GDA) of salt.

Mike Lean, chair of human nutrition at the university, said: “Labelling food as ‘extra special’ or ‘finest’ can be misleading for consumers who might expect health benefits at a higher price point.

The study found Sainsbury’s ‘taste the difference’ beef lasagne contains more than twice the saturated fat (77 per cent GDA) than its ‘basics’ version (36 per cent GDA).

It also contained more salt, with the luxury version accounting for 34.5 per cent of GDA compared to 28.8 per cent for the no-frills version.

Similarly, the supermarket’s ‘taste the difference’ shepherd’s pie contained 52.5 per cent of an adult’s recommended daily saturated fat compared to 22 per cent in one from the ‘basics’ range.

Tesco’s ‘finest’ cottage pie ready meals contained 39 per cent of GDA saturated fat compared with 18 per cent for the equivalent dish in the supermarket’s ‘value’ range. There was also twice as much salt, 52 per cent of GDA compared to 25 per cent.

The academics also found that Tesco’s ‘finest’ chicken masala contained far more saturated fat (68 per cent) than the value version (41 per cent).

Lack of family dinners and fast food fixation grows obesity in Britain

A lack of family dinners and a fast food fixation has led to a culture of obesity in Britain that has given it the highest proportion of overweight poor people in Europe.Lack of family dinners and fast food fixation grows obesity in BritainAn analysis published in The Lancet found that 29 per cent of poorly educated women in England and 27 per cent of men are obese.

It gives England the fattest proportion of people in Europe from this background – more than twice as many as Italy, Portugal, Spain and Ireland.

Britain’s culture of fast food, poor diet and lack of family dinners- particularly among people on lower incomes, was to blame said the experts.

The report showed wide health inequalities across Europe and warned that these would increase due to the economic climate.

Britain also has one of the higher rates of child poverty with 21 per cent of children living in households earning less than 60 per cent of the average income. This is higher than in some Eastern European countries including Hungary and Estonia.

Prof Peter Goldblatt, of the Institute of Health Equity at University College London, said: “Britain’s obesity problem is well documented, but the worse off you are, the more likely you are to be obese.

“One in eight children entering school in the most deprived areas is obese, compared to one in 16 in the richest. The difference increases through secondary school into adulthood.”

He said Britain had a culture of obesity. “In southern Europe, in particular, there is less fast food and more family dinners. They also have a generally healthy diet, containing a lot of fruit and vegetables.”

Adverts for junk food should be banned before TV watershed

Junk food advertising should be restricted before the TV watershed of 9pm to help tackle childhood obesity according to Britain’s leading children’s doctor.Adverts for junk food should be banned before TV watershedDr Hilary Cass, president of the Royal College of Paediatrics and Child Health, called on the authorities to stop showing marketing for unhealthy food to reduce its influence on children.

Current advertising regulations are too weak to prevent products that are high in salt, sugar and fat being promoted, Dr Cass said.

She argued the step was necessary because rates of obesity among children and young people had risen dramatically.

“Although they are trying to avoid junk food advertising around specific children’s programmes, you’ve still got it around soaps and other programmes that children watch,” she said.

“So the only realistic way to do it is to have no junk food advertising before the watershed at all.”

Dr Cass, who represents 11,500 children’s health professionals on behalf of the RCPCH, also claimed the Coalition should introduce taxes on soft drinks with high levels of sugar.

Earlier this year, experts backed a so-called “fat tax”, suggesting it could help reduce the number of deaths from heart attacks and strokes by half.

Professor Simon Capewell, from Liverpool University and co-author of the paper published by the European Association for Cardiovascular Prevention and Rehabilitation, said: “Much of the nanny state is manipulated by industry which leads to the nanny state generating very cheap junk food through subsidies at Common Agricultural Policy level, and an environment with advertising and marketing seducing us to buy junk food and sweet drinks.

“In this case the nanny state is malignant rather than benign and we’re looking to government to redress the balance.”

NHS turning to weight loss surgery to tackle obesity epidemic

The NHS is increasingly resorting to weight loss surgery to tackle Britain’s obesity epidemic- with the number of gastric bypass operations rising six fold in just five years.NHS turning to weight loss surgery to tackle obesity epidemicBritain’s men and women are among the fattest in Europe. Ministers want to tackle the problem at source- but surgeons say weight loss surgery is extremely effective for treating the morbidly obese.

Between 2006-7 and 2011-12 the number of gastric bypass operations increased from 858 to 5,407, according to figures from the NHS Health and Social Care Information Centre.

Over the same period the number of gastric band operations also increased, but at a slower rate, from 715 to 1,316.

A gastric bypass involves making the stomach much smaller and shortening the length of the small intestine. This makes it impossible to eat large meals and reduces absorption of nutrients.

It has become much more popular than gastric banding, which involves inserting an adjustable and removable band that limits the effective size of the stomach, but nothing else.

Surgeons said the increases indicated there was a large unmet need for weight loss (‘bariatric’) surgery, rather than any sizeable increase in the number of morbidly obese people since 2006.

Alberic Fiennes, president of the the British Obesity and Metabolic Surgery Society (BOMSS), said: “There are about 1.5 million such adults in the UK. They face premature death, disease and disability brought on as a direct result of their condition. These can be prevented, improved or eliminated by surgery.

“There is compelling evidence that weight loss surgery to treat the most severely affected is one of the most clinically effective, safe and cost effective treatments available.

American research indicates the morbidly obese could gain around three extra years of life from bariatric surgery. It also improves quality of life – besides weight loss – in some cases reversing patients’ Type 2 diabetes.

However, although there are national guidelines on who is eligible, some local health authorities refuse to adhere to them, leading to a postcode lottery of care.

Bariatric surgery is expensive – costing up to £14,000 a time – and there are too few qualified surgeons to meet demand. The NHS currently spends about £50 million on bariatric surgery.

Mr Fiennes called on the Department of Health “to invest in a long term strategy to ensure that all patients have equal access to this life-saving treatment.”

He also explained the gastric bypass operations had become the favoured option because they “may be more effective in the long term”.

Cheese eaters could reduce diabetes risk

Scientists say that cheese eaters could reduce their chances of developing type two diabetes by 12 per cent.Cheese eaters could reduce diabetes riskWhilst healthy eaters may try to avoid cheese new research suggests it could actually ward off diabetes.

The chance of developing type 2 diabetes, a condition often linked with obesity, could be reduced by around 12 per cent by regularly snacking on cheese, scientists said.

Although high in saturated fat, it may be rich in types of the fat that could be good for the body, they believe.

Fatty foods have long been thought to raise the risks, but uncertainty about the role of dairy products such as milk, butter, cheese and yogurt, has continued.

Most other dairy foods did not have the same beneficial effect as cheese, with the possible exception of yoghurt, the research found.

Type 2 diabetes is the most common type of the condition and occurs when the body does not produce enough insulin for it to function properly.

Symptoms can be controlled by eating a healthy diet and monitoring your blood glucose level, but sufferers may also need to take insulin medication.

The findings on the effect of cheese The amount and type of dairy product intake and incident type 2 diabetes: results from the EPIC-InterAct Study, published in the American Journal of Clinical Nutrition, come from one of the largest ever studies to look at the role of diet in health.

One reason why cheese lovers may be at less risk of diabetes could be that the fermentation process triggers some kind of reaction that protects against diabetes and heart problems, the researchers said.

More than half of over 40s are overweight

Some 52 per cent of people over the age of 40 say they are too heavy, compared with 40 per cent of younger people- but most are reluctant to try to lose weight through exercise.More than half of over 40s are overweightJust one in ten over 50s meet the recommended target of moderate exercise, such as fast walking, for half an hour, five times a week and a third admit to doing none whatsoever, the survey for Saga Health Insurance found.

While 37 per cent of over 50s who do not exercise said they were physically unable to, 31 per cent said they were not motivated to get fitter and 22 per cent described themselves as “too lazy”.

Of the over 50s who do exercise regularly, more than half said walking was their main form of exercise while 13 per cent swim and 10 per cent choose to cycle.

The Populus survey, which also included questions about participants’ diet, found that a third of over 50s eat the recommended five proportions of fruit and vegetable a day, compared with just a fifth of under-50s.

Fourteen per cent of the older group said they regularly exceed the recommended 21 units of alcohol per week, compared with just eight per cent of younger people.

Roger Ramsden, chief executive of Saga Services, said: “Whilst the over 50s tend to get it right with healthy eating, what they appear to need is something to motivate them to exercise.”
