Eating nutritional foods is one of the best ways to reduce obesity. But following a healthy diet isn't always easy, especially for lower socioeconomic groups.
One of the biggest barriers to buying good food is the cost, many experts say. Now researchers at Harvard School of Public Health have put a dollar amount on the price of healthy eating. By reviewing 27 studies on the cost of healthy vs. unhealthy foods, they've estimated the daily cost of eating better. Their results are published in the British Medical Journal.
"Conventional wisdom has been that healthier foods cost more, but it's never been clear if that's actually true or exactly how much more healthier foods might cost," said lead study author Mayuree Rao. "We found that the healthiest diets cost about $1.50 more per day, and that's less than we might have expected."

Efforts to increase healthy habits in American teens may be making an impact, according to a new study. Adolescents are moving more, eating better and watching less TV than they used to, and researchers say obesity rates in this group may finally be stabilizing.
The study results come a little more than a month after the Centers for Disease Control and Prevention announced it was seeing signs of progress in the fight against childhood obesity, especially in low-income families.
In the new study, published Monday in the journal Pediatrics, researchers analyzed data from three sets of students in grades 6 to 10. One set was surveyed during the 2001-2002 school year, another set during the 2005-2006 school year and the third set from the 2009-2010 school year. Researchers asked the students about their daily physical activity, nutrition, breakfast consumption, TV habits, and height and weight. They then compared the answers across the three school years to identify trends in healthy - or unhealthy - behaviors.

There's a strong link between sugary drinks and obesity. Scientific studies have shown that adults who consume more sugar-sweetened beverages tend to have higher body mass indexes, or BMIs, than their water-drinking counterparts.
But until now, this association hadn't been closely examined in kids younger than 5.
The American Academy of Pediatrics recommends that young children avoid all sugar-sweetened beverages. A new study, published in the organization's journal Pediatrics, offers further evidence to support that recommendation.

Skipping breakfast doesn’t mean you’ll consume more calories later in the day, according to a new report from Cornell University.
Researchers split 400 college-age students into two groups; they fed one group breakfast and the other no breakfast. They then tracked their eating habits throughout the day and measured the amount of calories they were consuming.
While the non-breakfast eating group reported feeling hungry by lunchtime, they didn’t consume larger lunches compared to the group who had eaten breakfast. In fact, the breakfast skippers had consumed roughly 400 fewer calories total at the end of the day.
“The problem in our culture is that we consume too many calories, and we have to look around at ways to help us consume less,” says David Levitsky, study author and professor of nutritional sciences and of psychology at Cornell.
“And we found that if you are trying to lose weight, then skipping breakfast isn’t necessarily the worst thing for you to do.”

Calorie counting has long been touted as an effective tool for losing pounds or maintaining a healthy weight. But new research published in the British Medical Journal shows many of us are underestimating the calories we're eating, especially when we visit fast food restaurants.
Researchers interviewed more than 1,800 adults, 1,100 adolescents and 330 children at several fast food chains in New England. The interviews were done at McDonald's, Burger King, Subway, KFC, Dunkin' Donuts and Wendy's around dinnertime and lunchtime.
Study participants were asked to estimate their meal's calorie count. Researchers then collected the bill to later tally the correct amount of calories using nutrition info posted on the chain's website. FULL POST

You’ve seen it added to cereal boxes, gallons of milk and bottles of orange juice. Experts tout its benefits – from strong bones to a strong immune system – and warn of the dangers of Vitamin D deficiency.
The public relations push is working; between 2002 and 2011, sales of vitamin D supplements increased from $42 million to $605 million, according to the Nutrition Business Journal.
New recommendations from the U.S. Preventative Services Task Force could bump those sales even higher, or - if critics are right - confuse consumers as they head down the pharmacy aisle.
After completing a review of existing research, the USPSTF, an independent panel of doctors and experts in prevention and evidence-based medicine, is advising against taking moderate amounts of Vitamin D and calcium supplements because there is not enough evidence to prove the supplements reduce the risk of bone fractures.

Americans are eating less fast food daily than they used to, according to a new report from the Centers for Disease Control and Prevention. But it's not much less.
Using data from 2007 to 2010, the CDC's National Center for Health Statistics determined adults eat, on average, 11.3% of their daily calories from fast food. That number was 12.8% in 2006– a one and half point difference.
As you would expect, younger adults tend to eat more fast food than seniors. People older than 60 eat approximately 6% of their daily calories from fast food. Among the younger age groups, non-Hispanic black adults eat the most fast food - using more than one-fifth of their daily calories at fast food establishments.
The CDC did not see a significant difference in fast food consumption based on income, according to the report. Only in the 20-to-39 age group did fast food consumption drop as income increased.
Fast food has been linked to the obesity epidemic in the United States. Not surprisingly, obese adults in each age group ate more of their calories from fast food.

Do bad nutrition habits like overeating or binge eating lead to smoking pot? Some health experts think they might, according to a study published Monday.
Habits like overeating have always been known to affect our health, nutritionists say. In some cases, people say they lose control and just can’t stop. Now scientists are finding that both habits and that feeling of lacking control may lead to other health issues.
Researchers at Boston Children’s Hospital studied a group of 16,882 boys and girls between the ages of 9 and 15 who participated in the Growing Up Today Study, beginning in 1996. From that time to 2005, investigators sent out questionnaires every 12 to 24 months, asking if these children were overeating or binge eating. Binge eating was defined as eating an amount of food that is larger than most people would eat in the same time span under similar circumstances and feeling a lack of control over eating during that time. Overeating did not have to be connected to loss of control.

It’s hard to argue with a $1 double cheeseburger. Perhaps that’s why so many believe that eating healthy is expensive.
The EWG has combined forces with anti-hunger group Share Our Strength to create a healthy shopping guide for low-income households: “Good Food on a Tight Budget.”
The guide contains lists of “best buys” – those that pack the most nutrition for the lowest cost – in each food group, cooking/shopping tips, recipes, a meal planner and a price tracker.

That morning cup o' joe or mid-afternoon coffee pick-me-up may play a role in keeping your heart healthy, depending on how much you drink.
A meta-analysis of five previously completed prospective studies finds that drinking two 8-ounce cups of coffee a day gives people an 11% lower risk of developing heart failure, compared to people who don't consume any coffee.
The analysis, published in the American Heart Association's journal Circulation: Heart Failure, reviewed five studies conducted between 2001 and 2011 and included a total of 140,220 patients.
"Heart failure shares risk factors with other cardiovascular diseases and high blood pressure and Type 2 diabetes are particularly strong risk factors for heart failure," explains Elizabeth Mostofsky, the first author of the analysis and a post doctoral research fellow at the Cardiovascular Epidemiology Research Unit at Beth Israel Deaconess Medical Center.
