Toward a Lower-Cesium Diet


A year after the nuclear accident in Fukushima caused a global scare about Japanese food safety, the country is trying to reassure the consuming public with stricter new standards on radiation contamination coming into effect this Sunday.

Livestock from Fukushima prefecture last July, after high cesium levels were detected in the prefecture’s beef.

The new rules tighten the country’s already tight limits on permissible levels of radioactive cesium — the most common source of long-term contamination after last year’s accident — in everything from drinking water to milk and meat.

The limit for drinking water will fall to one-twentieth of what it had been. For most foods, the new level will be one-fifth the old limits. Japan’s new standards will also include a separate, lower level for food given to infants, who, researchers say, are the most vulnerable to the effects of radiation.

Figuring out how much radiation is safe in food is a murky process. Scientists measure the radioactive content by tracking how many times each second radioactive energy is released by the cesium inside the food, a unit called a becquerel. After that, health authorities decide how much radioactive exposure their populations will tolerate annually from food, and how much exposure they’ll likely get from other sources.

The acceptable level assesses the anticipated physical impact of radiation. There’s also a lot of wiggle room to adjust assumptions to account for how worried people seem to be about it. The authorities then figure out how much contaminated food would have to be eaten, every day, to reach that level.

Japan’s new permissible level for drinking water, 10 becquerels per kilogram, is lower than that for milk, at 50 becquerels per kilogram, since the government assumes people will drink more water than milk.

Japan’s health ministry says the new standards bring Japan in line with some of the strictest recommendations from international bodies. The U.S. and European Union each have their own standards that permit considerably higher levels of radioactive cesium than Japan does. Their rules vary widely – both in how food categories should be grouped and in levels of radiation permissible. U.S. food-safety restrictions wouldn’t go into effect, for instance, until 1,200 becquerels of radioactive cesium had been detected per kilogram. The EU’s standard for radiation in food in the case of future nuclear accidents has one limit for liquids — 1,000 becquerels per kilogram — and another for other kinds of foods — 1,250 becquerels per kilogram.

Scientists say all those limits are far below levels of contamination where they can see any evidence of an effect on health.

Diet Plan For Fat Cat Moggies

ALWAYS on a diet, prone to catfights and with a name like Fifi Bottomley, you would be forgiven for thinking that this high-profile dieter made her name on The Only Way Is Essex.

In fact, Fifi, eight, is a morbidly obese moggy battling to lose the pounds in a competition run by an animal charity.

The Bradford-based cat weighs 9.3 kilogrammes – more than twice her ideal body weight – but has managed to cheat diet plans for years by stealing food from other cats and charming neighbours into feeding her.

She faces heavy competition from a roast dinner-loving Labrador from Tamworth, Staffordshire, who was too heavy to have an X-ray, a border collie from the Wirral whose excess pounds exacerbate his arthritis and a Wakefield rabbit named Samantha who weighs more than an average cat.

Complicated link between diet drinks, health: study


NEW YORK |
Wed Mar 28, 2012 4:15pm EDT

NEW YORK (Reuters Health) – Studies have hinted that diet-soda lovers could face higher risks of diabetes and heart disease, but new findings suggest that overall diet may be what matters most in the end.

Several studies have found that people who regularly down diet soda are more likely than people who don’t to have certain risk factors for those chronic diseases — like high blood pressure and high blood sugar.

And one recent study became the first to link the beverages to the risk of actual heart attacks and strokes (see Reuters Health story of February 17, 2012).

Still, researchers have not been able to say whether it’s the sugar-free drinks, themselves, that deserve the blame.

Many factors separate diet- and regular-beverage drinkers — and, for that matter, people who stick with water. Overall diet is one.

So this latest study tried to account for people’s general diet patterns, said lead researcher Kiyah J. Duffey, of the University of North Carolina at Chapel Hill.

She and her colleagues used data on more than 4,000 Americans taking part in a long-term study of heart health. They were all between the ages of 18 and 30 when the study began in the mid-1980s.

Over the next 20 years, 827 study participants developed metabolic syndrome — a cluster of risk factors for heart problems and diabetes including extra weight around the waist, unhealthy cholesterol levels, high blood pressure and elevated blood sugar.

. The researchers found that young adults who drank diet beverages were more likely than those who didn’t to develop metabolic syndrome over the next 20 years.

DIET MATTERS TOO

The picture became more complex when Duffey’s team considered the role of diet as well.

The lowest risk of metabolic syndrome was seen among people who drank no diet beverages and stuck to a “prudent” diet — one rich in foods like fruits, vegetables, whole grains and fish.

Meanwhile, people who also ate a prudent diet but did drink diet beverages had a somewhat higher rate of metabolic syndrome — but not by much.

Over 20 years, 20 percent of those men and women developed metabolic syndrome. That compared with 18 percent of prudent eaters who didn’t regularly have diet drinks, Duffey’s team writes in the American Journal of Clinical Nutrition.

Participants with the highest rate of metabolic syndrome — at 32 percent — were those who drank diet soda and downed the typical “Western” diet. That means lots of meat, processed foods and sugar.

Duffey’s team weighed factors other than diet, too, like people’s weight and exercise habits at the start of the study.

With all of that considered, healthy eaters who steered clear of diet drinks still had the lowest risk of developing metabolic syndrome — more than one-third lower than Western-style eaters who did drink diet beverages.

“I really think it’s overall diet that’s important,” Duffey said in an interview.

If you want to cut calories, replacing sugary drinks with sugar-free versions will do that, she noted. “But if the goal is a broader impact on your health,” she said, “you need to consider the whole diet.”

NO CLEAR ANSWERS YET

Duffey stressed that this study was observational — meaning it followed people over time, looking for links between eating and drinking habits and the risk of metabolic syndrome.

That type of study can’t prove that diet drinks have a negative effect on cardiovascular health, as some researchers have theorized, or whether some other factor is responsible.

That is still “definitely an open question,” said Hannah Gardener, a researcher at the University of Miami Miller School of Medicine who led the recent study linking diet beverages to an increased risk of heart disease and stroke.

“We’re still a long way from making any public health guidance” on diet beverages and health, Gardener told Reuters Health. It’s estimated about one-third of U.S. adults have metabolic syndrome — with older age and obesity being prime risk factors.

There’s some evidence from animal research that artificial sweeteners can end up boosting appetite and food intake. But no one knows yet if that translates to humans.

Whether diet drinks have specific health effects or not, Gardener agreed on the importance of overall diet.

“It’s very important to have a healthy, balanced diet,” she said.

And if you enjoy your sugar-sweetened drinks, Gardener said, “you shouldn’t think that simply switching to diet (drinks) is going to be enough without taking into consideration your overall diet.”

Q&A: Losing Weight Doesn’t Help Obese Girls Love Themselves — Can Parents?

From tough-love anti-obesity ads to dieting 7-year-olds, the fight against childhood obesity is escalating and everyone has a battle strategy. Yet the crusade is not without casualties and surprisingly, those carrying the heaviest emotional tolls are the kids that do shed pounds.

That’s what Purdue University researchers report in a new study on the effects of obesity stigma on teenage girls’ self-esteem. Published in the Journal of Health and Social Behavior, the study found that obese black and white teenage girls who transitioned out of obesity continued to see themselves as fat, despite physical changes from their weight loss. Obese white girls also had lower self-esteem than their normal-weight peers and their self-esteem remained low even when they lost weight. It turns out the effect of the stigma lingers long after the weight is gone.

Lead researcher Sarah Mustillo, an associate professor at Purdue University studying childhood and adolescent obesity, believes parents can play an active role in curbing their overweight child’s self-loathing. Healthland spoke with her about the study and how parents can guide their kids toward healthier weights without insinuating something is “wrong” with them.

(MOREChildhood Obesity: Most U.S. Schools Don’t Require P.E. Class or Recess)

Why do obese girls report strong insecurity issues at such young ages?

Studies have shown that in general, people in the U.S. tend to internalize the negative stereotypes we have of obese people. It starts at a very young age. Studies show 3-year-olds have negative stereotypes of obese people. These stereotypes are part of our society and we learn them through peers and social interactions. Kids learn these before they become obese themselves. Then when they do become overweight, these stereotypes become about them.

Why are negative feelings of self-worth so difficult to shake even after weight loss? Can positive self-images return?

In our study, we found that girls appeared to be integrating their obesity into their identity. Being overweight becomes a part of who they are. Shedding weight is a physical change, but changing how you view yourself is very different. It is a much longer process, but I do believe it is possible to have an identity transformation. People who experience a change can take a while to adapt. When someone gets divorced, it takes them a while to view themselves as a divorced person rather than a married person. Big changes take time.

In the study, black girls who moved into the normal weight range experienced more increased self-esteem than any other group of girls. Why is there a difference in confidence rebounds among races?

This is total speculation, but our thinking is that studies have shown in the black community, especially when it comes to black women, there are different ideals about body and size. In the African American community there tends to be more acceptance of a wider range of body types. This could be because African Americans experience stigmas in other areas and reject the white image of beauty and have their own image.

How can parents ensure their overweight child understands the importance of being healthier without feeling bad about themselves?

There are a couple ways parents can do this. First, parents should focus on the health aspects of weight loss and not the appearance aspects. Focus on how it will be easier to walk up and down stairs, how gym class will be better, they will have more energy. Don’t say, “Your clothes will fit better.” Don’t talk about appearance, just focus on health. In terms of preventing them from feeling bad about themselves, a child needs to know their value comes from who they are as a person and not what they look like. In terms of identity formation, teens develop their identity based on their personal characteristics and roles. Help them identify with the positive roles in their life, like being a musician or an artist. Encourage them to get their sense of self from being a good artist instead of how they look. It will help counter the negative feedback they get. Focus on the positive and find something they can participate in and excel at.

How can parents treat their child’s emotional damage from teasing at school and the public stigma of obesity?

First off, parents need to realize they can actually have a bigger impact on their kids’ views of themselves than their kids do. First and foremost, we need make sure the parents are not contributing to the problem. Sometimes it’s inadvertent. Sometimes it is saying things like, “You look great in these pants.” Parents may mean it as a compliment, but the child hears, “Given how big you are, you look good in these pants.” Parents need to examine their own stereotypes of obesity and make sure they do not share them at home. Kids pick up on these attitudes. Some parents say things directly, and some parents may not say things not about their child, but about other people in public. For instance, “That lady on the bus is huge.” Parents may think, “I am not talking about my kid, so they won’t be offended,” but saying a person is not a good person due to their size is harmful.

Communication is also really important. Parents can’t combat the negative feedback if they don’t know what children are hearing. Really try to open up communication. If your child won’t talk about it, look for other cues like social isolation. Parents can really take an active role in helping their child process the negative messages they are getting. If the parent teaches the child about bullying and teasing, it explains more about what the other kids are doing wrong than what is wrong with their child. You don’t focus on the weight of the child, but what is really wrong with the other kid that they are treating them poorly.

A recent essay in Vogue by a mother who put her 7-year-old on a strict diet is sparking outrage. What do you recommend for parents who need to take measures for their child’s weight loss?

From what I know, it is more effective to emphasize the positive than eliminate the negative. Push the benefits of eating yogurt instead of junk food. Encourage your kids to eat fruits and veggies and whole grains as opposed to really strictly limiting particular foods. Parents also have a choice of what they put in the house. If you don’t want your kids eating garbage, don’t buy it. In terms of messages, it is far more effective to be a model for your kids. Get out there and exercise and take your kids with you. I drive my kids crazy trying to get them to go running with me. It is good to keep active and have our kids see us doing that.

Do you think current anti-obesity campaigns are doing a good job?

I think our current emphasis on combating childhood obesity is a good thing. It is an issue that needs attention and putting it in the spotlight is a good thing. Lets Move! is very positive. But I would love to see them incorporate more messages for building self-esteem. Ideally, in terms in combating stigma, we would not let these negative stereotypes happen. If they didn’t exist, kids wouldn’t feel bad about being overweight. But that’s unrealistic. If we can get kids to base their identity on something other than appearance, all kids can benefit from that. We need to teach kids not to base self-worth on what you look like and how to locate self-esteem in something besides appearance. As kids do lose weight, we also need to work on assisting them to change their perceptions of themselves. In our study, as kids lost weight, they continued to see themselves as heavy. We need to help them update their vision of themselves.
