Fast food restaurant chains have slowed down televised advertisements, but they are ramping up efforts to market to younger customers by using social media outlets, according to a new study by the Yale Rudd Center for Food Policy & Obesity. More from Time.com:

The researchers studied 18 of the top fast food chains in the U.S. and documented the changes in the nutritional quality of the food they served, as well as their marketing campaigns to kids and teens on TV and online.
Since 2010, kids between the ages of 6 to 11 saw 10% fewer TV ads for fast foods, and more of these ads included healthier meals, such as fruit snacks and salads.
But the positive trend also hid some less encouraging news. While the youngest kids were seeing fewer TV ads, older kids and teens still saw about three to five fast food advertisements on television every day. Appeals to teens on social media also surged, and while children saw more advertisements for healthier fast food options, these made up only a quarter of the fast food ads viewed by these kids, and only 1% of kids’ meals at these chains met healthy nutritional standards.
The results highlight the challenge that families face in improving children’s diets, as such enticements to consume high calorie, high fat meals continue to surround them. A recent study published in the journal PLOS One reported, for example, that fast food ads targeting kids were more likely to include toys and giveaways, which are a nearly irresistible draw for younger kids. And research suggests that these types of marketing campaigns seed lasting emotional connections to brands, making children more likely to continue eating at fast food chains and take their own families there as adults.

A diet heavy in bacon and other processed meats may raise a man’s risk of having poor sperm and semen quality, whereas a diet rich in fish could boost male fertility, according to a new study published in the journal Fertility and Sterility. More from CNN:
Myriam Afeiche, research fellow at the Harvard School of Public Health, and her colleagues looked at how types of meat could be associated with semen quality. They took samples from 156 men at the Massachusetts General Hospital Fertility Center in Boston and had the men answer a questionnaire about their eating habits.
What does semen have to look like to be considered high-quality? The researchers considered four main parameters:
The concentration of sperm is one part of it. So is motility, or how fast the sperm move. The shape of the sperm also matters, as does the total sperm count – that’s the concentration multiplied by volume.
The researchers did not look at individual kinds of processed meat, so this study won’t tell you if bacon could be more sperm-stunting than hamburgers, or vice versa. But higher intake of processed meat appeared to be related to a lower percent of “morphologically normal” – or well-shaped – sperm.
Regarding fish, it seemed that men who ate more dark meat fish – such as salmon, bluefish and tuna – had higher total sperm count; more white meat fish – such as cod and halibut – was associated with normally-shaped sperm.
The researchers only looked at associations, not causes. It is unclear whether processed meat actually causes changes in sperm, or if it does, how that would happen. It’s possible men who eat more processed meat have an unhealthier diet overall, which could affect their semen. Same goes for fish intake and sperm; researchers don’t know what about fish may benefit the littler swimmers.
“There might be something else going on, but we’re not sure what it is,” Afeiche said.

American kids and teens are watching slightly less television, and getting slightly more exercise, than they were 10 years ago, according to a new report published in the journal Pediatrics. Unfortunately, the findings don’t also report a decline in childhood obesity rates, but they are an encouraging sign nonetheless. More from NBC News:
Using surveys conducted in middle and high schools, researchers also found increases in the number of days youth reported having breakfast each week and in how often they ate fruits and vegetables. Those trends have corresponded to a leveling off in obesity rates, but not a decline, the study showed.
“I would like to believe that all the public health efforts focusing on increasing physical activity and increasing fruit and vegetable consumption are having an effect, because that seems to be a pattern,” Ronald Iannotti, the lead author on the study from the University of Massachusetts Boston, said.
“The fact that (obesity) is leveling off, that’s a surprise and a major change from the steady increase that we’ve seen,” Iannotti, who worked on the study while at the Eunice Kennedy Shriver National Institute of Child Health and Human Development in Bethesda, Md., said. “This is great news.”
He and co-author Jing Wang analyzed surveys given to a nationally representative sample of students in 6th through 10th grades in 2001-2002, 2005-2006 and 2009-2010 as part of the Health Behavior in School-aged Children study. Each survey period included responses from between 9,000 and 15,000 adolescents.
The researchers found “encouraging” trends on measures of most diet and lifestyle habits.
For example, the number of days each week that kids reported being physically active for at least 60 minutes increased from 4.3 in 2001-2002 to 4.5 in 2009-2010, with similar trends among boys and girls. Likewise, youth reported eating breakfast on three school days each week on the first survey and 3.3 days on the last.
The average number of hours students spent watching TV each day fell from 3.1 to 2.4, with drops in both weekday and weekend viewing.
Frequency of fruit and vegetable consumption also rose slightly – although it remained at less than one daily serving of each, on average – and consumption of sweets and soft drinks fell.
However, the proportion of survey participants who were overweight or obese, based on their own height and weight reports, did not decrease, the researchers wrote Monday in Pediatrics.

Mothers who get healthy amounts of vitamins from their diets during pregnancy tend to have children who have stronger bones – at birth, and years later. The New York Times has more on the new study that made this connection:
The research followed nearly 3,000 women during their pregnancies and then looked at whether their diets were linked to bone mass in their children later on. The scientists had the women record what they ate each day and measured concentrations of vitamins in their blood. Then, when the children were roughly 6 years old, the researchers carried out imaging tests to assess their bone mass.
The study found that the children whose mothers consumed more protein, phosphorus and vitamin B12 when they were pregnant had the greatest bone mass and bone mineral content. The researchers also found that higher consumption of carbohydrates and greater blood concentrations of homocysteine – an amino acid that accumulates in response to a deficiency in B vitamins – were associated with lower bone mass and mineral content.
The study, which was published in The American Journal of Clinical Nutrition, could not rule out the possibility that expectant mothers who ate more vitamin-rich foods simply went on to provide their young children with more healthful diets. But the researchers said they suspected that there was a more direct relationship and that “fetal nutritional exposures may permanently influence bone development.”

The foods that many American babies and toddlers are eating contains too much sodium, according to new information compiled by the Centers for Disease Control and Prevention and presented to a scientific meeting of the American Heart Association. Consuming too much sodium can lead to elevated risk of heart disease and high blood pressure, among other things. From a release announcing the findings:
In the first study to look at the sodium content in U.S. baby and toddler foods, researchers compared the sodium content per serving of 1,115 products for babies and toddlers using data on major and private label brands compiled by the U.S. Centers for Disease Control (CDC). Baby food was categorized as intended for children less than one year old, and toddler food was categorized as intended for children between the ages of one and three.
A product was defined as high in sodium if it had more than 210 mg of sodium per serving. Toddler meals had significantly higher amounts of sodium than baby meals, and the amount of sodium in some of the toddler meals was as high as 630 mg per serving – about 40 percent of the 1,500 mg daily limit recommended by the American Heart Association. The foods with the most sodium were savory snacks and meals for toddlers.
“Our concern is the possible long-term health risks of introducing high levels of sodium in a child’s diet, because high blood pressure, as well as a preference for salty foods may develop early in life. The less sodium in an infant’s or toddler’s diet, the less he or she may want it when older,” said Joyce Maalouf, M.S., M.P.H., ORISE, lead author and Fellow at the National Center for Chronic Disease Prevention and Health Promotion at the Centers for Disease Control and Prevention in Atlanta, Georgia.
The American Heart Association recommends limiting sodium consumption to less than 1500 mg a day. Sodium is in regular table salt and many foods, including most prepared meals and snacks for toddlers.
The CDC listed the following 10 foods as the biggest sodium culprits affecting Americans from ages 2-19:
- Bread and rolls
- Cold cuts and processed meats
- Savory snacks
- Mixed pasta dishes
- Frankfurters and sausages
