Pesky! Children who drink full fat milk weigh less than those who do not

Children as young as eight who drink milk every day have a lower body mass index than those who drink the low fat variety, according to the study from Gothenburg University in Sweden. The new study found that children who drink full fat milk weigh on average almost nine pounds less than other children.

Diet experts believe that children who do not drink full fat milk may be fatter themselves because they drink fizzy drinks instead. Dietician and author of the study Susanne Eriksson, said: "It may be the case that children who drink full-fat milk tend also to eat other things that affect their weight. "Another possible explanation is that children who do not drink full fat milk drink more soft drinks instead."

The researchers also discovered a difference between overweight children who drink full fat milk everyday and those who do not. Children who often drink milk with a fat content of three per cent are "less overweight" but eat more saturated fat than recommended. However, those children with a high intake of fat have a lower BMI than the children with a lower intake of fat.

Miss Eriksson examined the nutrition, body composition and bone mineralisation of 120 healthy eight-year-olds after the children told her team what they had eaten the day before, how often they ate certain foods and after taking blood samples. Many of these children had been examined when they were four-years-old, and we discovered that their eating habits were pretty much unchanged four years later. "It appears to be the case that eating habits are established early."

The study found that nearly two-thirds of the children had low levels of Vitamin D in their blood.


Technology doesn't cause social isolation: Pew study

I wonder is the slimy "Baroness" Greenfield listening?

CONTRARY to popular belief, technology is not leading to social isolation and people who use the internet and mobile phones have larger and more diverse social networks, a new study claims. "All the evidence points in one direction," said Keith Hampton, lead author of the report by the Pew Internet and American Life Project released this week.

"People's social worlds are enhanced by new communication technologies. "It is a mistake to believe that internet use and mobile phones plunge people into a spiral of isolation," said Mr Hampton, an assistant professor of communication at the University of Pennsylvania.

The authors said key findings of the study "challenge previous research and commonplace fears about the harmful social impact of new technology." "There is a tendency by critics to blame technology first when social change occurs," Mr Hampton said. "This is the first research that actually explores the connection between technology use and social isolation and we find the opposite. "It turns out that those who use the internet and mobile phones have notable social advantages," Mr Hampton said. "People use the technology to stay in touch and share information in ways that keep them socially active and connected to their communities."

The study found that six per cent of Americans can be described as socially isolated - lacking anyone to discuss important matters with or who they consider to be "especially significant" in their life. That figure has hardly changed since 1985, it said.

The study examined people's discussion networks - those with whom they discuss important matters - and their closest and most significant confidants, or core networks. On average, the size of people's discussion networks is 12 per cent larger among mobile phone users, nine percent larger for those who share photos online, and nine percent bigger for those who use instant messaging.

The diversity of people's core networks tends to be 25 per cent larger for mobile phone users, 15 per cent larger for basic internet users, and even larger for frequent internet users, those who use instant messaging, and those who share digital photos online. At the same time, the study found that Americans' discussion networks have shrunk by about one-third since 1985 and have become less diverse because they contain fewer non-family members.

The study found that on average in a typical year, people have in-person contact with their core network ties on about 210 days. They have mobile-phone contact on 195 days of the year, landline phone contact on 125 days and text-messaging contact on the mobile phone 125 days. They have email contact on 72 days, instant messaging contact on 55 days, contact via social networking websites on 39 days and contact via letters or cards on eight days.

The US study involved telephone interviews with 2512 adults between July 9, 2008 and August 10, 2008 and has a sampling error of 2.1 per cent.
