New F.D.A. Nutrition Labels Would Make ‘Serving Sizes’ Reflect Actual Servings

The Food and Drug Administration for the first time in two decades will propose major changes to nutrition labels on food packages, putting calorie counts in large type and adjusting portion sizes to reflect how much Americans actually eat.

It would be the first significant redrawing of the nutrition information on food labels since the federal government started requiring them in the early 1990s. Those labels were based on eating habits and nutrition data from the 1970s and ’80s, before portion sizes expanded significantly, and federal health officials argued that the changes were needed to bring labels into step with the reality of the modern American diet.

“It’s an amazing transformation,” said Dr. Margaret A. Hamburg, commissioner of the F.D.A. “Things like the size of a muffin have changed so dramatically. It is important that the information on the nutrition fact labels reflect the realities in the world today.”

The proposed changes include what experts say will be a particularly controversial item: a separate line for sugars that are manufactured and added to food, substances that many public health experts say have contributed substantially to the obesity problem in this country. The food industry has argued against similar suggestions in the past.

“The changes put added sugars clearly in the cross hairs,” said Dr. David A. Kessler, who was commissioner during the original push for labels in the 1990s. “America has the sweetest diet in the world. You can’t get to be as big as we’ve gotten without added sweeteners.” Millions of Americans pay attention to food labels, and the changes are meant to make them easier to understand — a critical step in an era when more than one-third of adults are obese, public health experts say. The epidemic has caused rates of diabetes to soar, and has increased risks for cancer, heart disease and stroke.

The proposal will be open to public comment for 90 days, and it will take months before any change is made final. In a special concession to industry, the agency is allowing companies two years to put the changes into effect.

MMR vaccine linked to lower risk of serious infections

The MMR vaccine may not only protect you from measles, mumps, and rubella — it may lower your risk of contracting other serious infections as well, according to a new study from Statens Serum Institute in Denmark.

Dr. Signe Sørup, lead author of the paper, said that the findings underscore the numerous benefits of following the immunization schedule that has been a mainstay of public health since the 1970s. “MMR may have a general immune stimulating effect preventing hospital admissions for unrelated infections,” she wrote in an email to Medical Daily. “It highlights the importance of receiving the MMR vaccine on time.”

The study, which is published in the Journal of the American Medical Association, surveyed nearly half a million Danish children born between 1996 and 2006. Over a period ranging from 11 months to two years, the researchers tracked immunization among these children. Besides an MMR shot at 15 months, the recommended vaccine schedule included shots for diphtheria, tetanus, pertussis, polio, and Haemophilus influenzae type b (DTaP-IPV-Hib) administered at three, five, and 12 months.

The researchers found that receiving the MMR vaccine on time — that is, after the DTaP-IPV-Hib shot — corresponded to a lower risk of being involved in one of the 56,889 hospital admissions for general infections attributed to the sample. This relationship was particularly clear for lower respiratory tract infections and complications requiring longer hospitalization. But while the results point to new benefits, they also illuminate a waning compliance with public health recommendations.

“The coverage with MMR is suboptimal in many high-income countries; in the present study, about 50 percent of children were not vaccinated on time,” Sørup and colleagues write. “Physicians should encourage parents to have children vaccinated on time with MMR and avoid giving vaccinations out of sequence, because the present study suggests that timely MMR vaccination averted a considerable number of hospital admissions for any infection between ages 16 and 24 months.”

The better your mood the healthier you eat!

Previous research has found that emotions affect eating, and that negative moods and positive moods may actually lead to preferences for different kinds of foods. For example, if given the choice between grapes or chocolate candies, someone in a good mood may choose the former while someone in a bad mood may choose the latter. The research reported in this article looks at the “why:” Why, when someone is in a bad mood, will they choose to eat junk food and why, when someone is in a good mood, will they make healthier food choices?

To get at the “why,” we married the theories of affective regulation (how people react to their moods and emotions) and temporal construal (the perspective of time) to explain food choice. Conceptually, when people feel uncomfortable or are in a bad mood, they know something is wrong and focus on what is close in the here and now. We hypothesized and demonstrated that this kind of thinking gets us to focus on the sensory qualities of our foods – not things that are more abstract like how nutritious the food is. Analogously, we hypothesized and demonstrated that when people are in a good mood, things seem okay and they can take a big picture perspective. This kind of thinking allows people to focus on the more abstract aspects of food, including how healthy it is.

We studied these hypotheses in four laboratory experiments. In the first study, we investigated the effect of a positive mood on evaluations of indulgent and health foods by examining 211 individuals from local parent-teacher associations (PTAs). Next we studied whether individuals in a negative mood – who had read a sad story– evaluated indulgent foods more positively and whether those who were in a positive mood indicated a desire to remain healthy into their old age. 315 undergraduate students participated in this study. In the third study, involving 151 undergraduate students, we altered participants’ focus on the present versus the future along with their mood and measured how much healthy and indulgent food they consumed. To get more direct insight into the underlying process, the fourth study, involving 110 university students, focused specifically on the thoughts related to food choice and differentiated concrete taste versus nutrition benefits.

Ultimately, the findings of all the studies combined demonstrated that individuals select healthy or indulgent foods depending on whether they are in a good or a bad mood, respectively. The findings also indicate the integral aspect of the time horizon, showing that individuals in positive moods who make healthier food choices are often thinking more about future health benefits than those in negative moods, who focus more on the immediate taste and sensory experience. Finally we found that individuals in negative moods will still make food choices influenced by temporal construal which suggests that trying to focus on something other than the present can reduce the consumption of indulgent foods.

Eating vegetarian diets may help lower BP

A new study has revealed that eating a vegetarian diet is associated with lower blood pressure (BP), and the diets can also be used to reduce blood pressure.

Factors such as diet, body weight, physical activity and alcohol intake play a role in the risk of developing hypertension. Dietary modifications have been shown to be effective for preventing and managing hypertension.

The authors analyzed seven clinical trials and 32 studies published from 1900 to 2013 in which participants ate a vegetarian diet. Net differences in BP associated with eating a vegetarian diet were measured.

In the trials, eating a vegetarian diet was associated with a reduction in the average systolic (peak artery pressure) and diastolic (minimum artery pressure) BP compared with eating an omnivorous (plant and animal) diet.

In the 32 studies, eating a vegetarian diet was associated with lower average systolic and diastolic BP, compared with omnivorous diets.

The study was published in the journal JAMA.

Body Shape Index is Better Predictor of Mortality

In 2012, Nir Krakauer, an assistant professor of civil engineering in City College of New York’s Grove School of Engineering, and his father, Jesse Krakauer, developed a new method to quantify the risk specifically associated with abdominal obesity.

A follow-up study, published in PLoS ONE, supports their contention that the technique, known as A Body Shape Index (ABSI), is a more effective predictor of mortality than Body Mass Index (BMI), the most common measure used to define obesity.

The team analyzed data for 7,011 adults, 18+, who participated in the first Health and Lifestyle Survey (HALS1), conducted in Great Britain in the mid-1980s, and a follow-up survey seven years later (HALS2). The sample was broadly representative of the British population in terms of region, employment status, national origin and age. They used National Health Service records through 2009 to identify deaths and cancer cases: 2,203 deaths were recorded among the sample population.

Then, they compared all-cause mortality from the HALS sample with ABSI and other variables, including BMI, waist circumference, waist – hip ratio and waist – height ratio.

The analysis found ABSI to be a strong indicator of mortality hazard among the HALS population. Death rates increased by a factor of 1.13 (95 percent confidence interval, 1.09–1.16) for each standard deviation increase in ABSI. Persons with ABSI in the top 20 percent were found to have death rates 61 percent than those with ABSI in the bottom 20 percent.

The results tracked closely with the earlier study, which used data from the National Health and Nutrition Examination Survey (NHANES), conducted in the U.S. between 1999 and 2004. This provides stronger evidence that ABSI is a valid indicator of the risk of premature death across different populations. Further, they showed that ABSI outperformed commonly used measures of abdominal obesity, including waist circumference, waist – hip ratio and waist – height ratio.

Also, because the data came from two surveys seven years apart, the researchers were able to assess the effect of change in ABSI on mortality. The found an increase in ABSI correlated with increased risk of death, and that the more recent ABSI measurement was a more reliable predictor. Noting this, the researchers contend that further investigation is warranted into whether lifestyle or other interventions could reduce ABSI and help people live longer.

Eating barbecued, fried food linked to Alzheimer’s

A new study has revealed that eating a meat-rich diet, which has been fried, barbecued or grilled, can trigger Alzheimer’s disease and accelerate ageing.

Scientists have discovered that harmful ‘Ages’ compounds in the “Western diet” cause a build-up of a dangerous protein that forms toxic deposits which ravage the brain, the Daily Express reported.

Researchers found that the high levels of these compounds suppress a protective enzyme concerned in conditions related to brain, metabolic disease, ageing and diabetes.

The study has also found that fatty and sugary foods, like cheese, eggs, white bread, pasta and sugary pastries, cakes and biscuits could also play a part in Alzheimer’s by boosting Ages levels.

Dr Simon Ridley, head of research at Alzheimer’s Research UK, said that diabetes has previously been linked to an increased risk of dementia, and this new study provides fresh insight into some of the possible molecular processes that may link the two conditions.

Ridley added that eating a balanced diet can help lower the risk of Alzheimer’s and following a healthy lifestyle, which includes regular exercise, not smoking, and keeping blood pressure and weight in check can also be helpful.

The study was published in the journal Proceedings Of The National Academy Of Sciences.

Lack of exercise and high fat diet fueling obesity epidemic in Europe

The World Health Organisation (WHO) has warned that lack of physical inactivity and diets high in fats, salts and sugars has led to obesity and overweight is becoming “the new norm” throughout Europe.

Up to 27 percent of Europe’s 13-year-olds and 33 percent of 11-year-olds are overweight, officials said ahead of an EU summit in Greece with a special focus on “the grave public health concern” of childhood obesity.

Countries with the highest proportion of overweight 11-year-olds included Greece, with 33 percent, Portugal (32 percent), and Ireland and Spain, both with 30 percent, the Independent reported.

Overall the UK is performing slightly better, but in Wales 30 percent of 11-year-old boys are overweight.

The WHO’s regional director for Europe, Zsuzsanna Jakab, said that Europeans’ “perception of what is normal has shifted”.

She said that being overweight is now more common than unusual, adding that we must not let another generation grow up with obesity as the new norm.

Inactivity, listed by the WHO as the fourth leading cause of death globally, is now viewed as one of the major health threats affecting developed countries.

In the UK more than two thirds of people over the age of 15 were insufficiently active, according to the WHO’s latest data, from 2008.

It is recommended that adults get 150 minutes moderate-intensity exercise per week, while children and adolescents should have an hour per day, according to international guidelines.

An adult in the pediatric ward: What the littlest Cancer Avengers taught me

140217161534-little-superheroes-ann-and-andreas-horizontal-gallery

Three years ago, I was diagnosed with a rare pediatric bone cancer called osteosarcoma. In my case, it was super-rare, because I was 43.

I went to see Dr. Paul Meyers at Memorial Sloan Kettering Cancer Center in New York, six hours away from our home in upstate New York. At the hospital, my husband and I followed instructions to the B elevators and got off on the eighth floor.

The doors opened to a brightly colored playroom, funky lounge chairs and really big fish tanks.

Meyers is a pediatric oncologist, and because I had a pediatric cancer (age not withstanding), I would be treated where he worked: in the pediatric cancer center.

Meyers explained, sans sugar-coating, that my cancer was particularly aggressive, and so the treatment would be, too. I explained that I loved my job and my life, and am one tough chick, so I planned on working through it all.

Meyers pressed on. I would endure nine rounds of three types of chemotherapy in a not-so-delicious-chemo cocktail. After three rounds, there would be limb-salvage surgery where they remove my cancerous bones and replace them with titanium. Or amputate.

I should expect to be fully debilitated by this treatment, Meyers said — to be in a wheelchair for more than a year, to stop working at my job that I loved, and to close my company that I had worked hard to build. Long-term damage to my hearing, heart, bladder and extremities because of high doses of chemo were to be expected.

At the time, I was unsure of almost everything, including how I felt about being in the Pediatric Day Hospital as a patient.

We learned the hospital would be my home away from home during my nearly yearlong treatment. I spent at least one week of every month with the sickest people you can imagine. Little people with no hair, missing limbs and treacherous looking scars; it was harrowing at first.

Then I became one of them: No hair. Giant, treacherous scar. Wheelchair. Ever-present IV pole, and dusty-rose colored kidney-shaped bowl to throw up in. These were all outward signs of a fraternity of warriors that no one wants to belong to. They all were enduring the same grueling treatment I was — only they were, on average, 10 years old.

This fraternity of Cancer Avengers was wise in ways beyond their years. When faced with the courage and bravery of these little superheroes, I had to give myself the “Put your big girl pants on” speech more than once.

On my first day of treatment, while I was scrolling through my Facebook feed by the fish tank, two boys next to me started discussing their Make-A-Wish requests. Adam, about 12 years old, had just returned from a rainforest trip and asked what Sam’s wish was going to be. Sam said they couldn’t give him what he wished for. Adam disagreed, enthusiastically conveying that any wish could be granted. Sam stood firm: It was not possible.

Well, what is it that you want anyway? Adam wanted to know. By now, I also wanted to know.

“I want normal,” was Sam’s answer. “I want to go to school and basketball practice, complain about my parents and homework and turn 12.”

Silence from Adam. Silence all around. Even a superhero knows when he is defeated.
I looked down at my phone, trying to distract myself and read through my tears. A Facebook friend was complaining about turning 44. In the moment, it was like complaining about being too rich or having too much food to eat. My friend had been granted 32 more years than this kid dared dream of living. So had I.

Call for Shake-Up in Africa Nutrition Research

Rwanda has achieved remarkable success in reducing child hunger, and nutrition experts believe there may be lessons here for other countries in Africa.

The UN Children’s Fund (UNICEF), in a 2013 report on progress in tackling malnutrition, noted that in 2005 more than half of Rwanda’s children under five years of age – about 800,000 – were stunted. “Just five years later, stunting prevalence had decreased from an estimated 52 percent to 44 percent,” the report said.

The Rwandan approach has been to try and find home-grown solutions.

It scaled up community-based nutrition programmes in all 30 of the country’s districts, and has also been setting up an almost universal community-based health insurance scheme. “This was all done with the help of food grown locally, and not packaged interventions provided by donors,” said Fidele Ngabo, director of Maternal Child Health. “There are thousands of local solutions for hunger…

“Each village comes up with community-based approaches to tackle malnutrition and food insecurity that don’t cost money – we are at the centre to provide support and play a monitoring role,” she said.

Examples include the setting up a communal grain reserve to which each household contributes at least 20 percent of their harvest during a good season, with the stored grain being used during the lean season; or the expansion of kitchen gardens with shared information on the vegetables to be grown.

Suggestions and proposed solutions are debated in working groups comprising aid agencies, researchers, academics and government officials.

6 ways to have a healthy online life

The average tween or teen consumes nearly 11 hours of media a day, according to research from the Kaiser Family Foundation, and scientists are raising concerns about how all that screen time is affecting young people.

That 11-hour average shows how multitasking has become routine for young people. For example, in the 2010 Kaiser study, one hour of watching videos while simultaneously texting would count as two hours of media consumption.

But even without factoring in multitasking, the screen-time numbers young people are racking up are astonishing. Surveys by market researcher Ipsos Mobility last fall show that on school days Canadian teens spend five hours a day just on their smartphones — texting, social networking, gaming, and watching videos.

Scientists worry it’s producing distracted kids who have a hard time focusing and thinking deeply or analytically.

Some educators and parents say anxiety is climbing in kids who spend so much time curating multiple online profiles, keeping up with hundreds of digital friends, and picking their way through the sometimes nasty world of social media and online bullying.

But experts say there are ways to counteract some of those effects, and ensure that kids have a healthier online life.
