– men selvfølgelig billigere og nemmere at ignorere. Så er rådet der skal afløse det nedlage nationale råd for Folkesundhed og det savnede Motions- og Ernæringsråd nedsat. Læs hvem ministeren har valgt som sine nye debaterende rådgivere i stedet for det vidensproducerende motions- og ernæringsråd.
Happiness is infectious
Dec 5
BMJ has this wonderful story based on 4739 individuals followed from 1983 to 2003 in the Framingham Heart Study. Happiness measured with validated four item scale; broad array of attributes of social networks and diverse social ties. People who are surrounded by many happy people and those who are central in the network are more likely to become happy in the future. Longitudinal statistical models suggest that clusters of happiness result from the spread of happiness and not just a tendency for people to associate with similar individuals.
James H Fowler and Nicholas A Christakis concludes that people’s happiness depends on the happiness of others with whom they are connected. This provides further justification for seeing happiness, like health, as a collective phenomenon.

The link between food marketing and the growing childhood obesity epidemic is the focus of a $6.4 million grant from the Robert Wood Johnson Foundation to the Rudd Center for Food Policy and Obesity at Yale University. The researchers are excited that the Foundation has agreed to fund such an extensive analysis of the scope and impact of food marketing practices targeted to youth. Expected outcomes include a Youth Marketing Index to identify and quantify the best and worst food marketing practices targeted at youth.
In a German online study (n = 494) on fruit and vegetable intake, social-cognitive variables and stages were assessed at baseline and stage transitions 4 weeks later. Transitions between the preintention, intention and action stage were predicted by social-cognitive variables using binary and multinomial logistic regression analyses. Outcome expectancies predicted progression from the preintention stage, whereas social support predicted progression to the action stage. Low levels of planning were associated with relapse to the preintention and the intention stage. Self-efficacy emerged as a universal predictor of stage transitions.
Distinct and tailored programs are suggested for reinventing social marketing programs focused on increasing fruit and vegetable consumption in each psychographic audience segment. The authors also discuss the implications of utilizing a consumer-based psychographic audience segmentation versus a more traditional readiness-to-change social marketing segmentation.
The current consensus is that the minimum amount of physical activity needed to improve and maintain good health is 30 min moderate-intensity activity/d on >/=5 d/week. The evidence supporting this consensus is based on predominantly observational evidence that performing regular aerobic (endurance)-type physical activity is associated with reduced morbidity and premature mortality from CVD, CHD, stroke and colo-rectal cancer. The exact dose needed to improve health and the slope of the dose-response gradient between physical activity and mortality for various diseases are not known, and one major limitation of the existing evidence is the lack of objective measurement of physical activity. Limited evidence indicates that a much higher dose of activity (45-90 min each day on >/=5 d/week) may be needed to prevent overweight and obesity and to avoid weight regain in previously overweight and obese individuals.
A new study performed by researchers from the Yale University School of Medicine, National Institutes of Health, and California Pacific Medical Center about the impact of media on children’s health looked at the best studies on media and health from the last 30 years and found that 80 percent of them showed that greater media exposure led to negative health effects in children and adolescents.

The best article yet on food and climate change was published in The New York Times yesterday. Dr. Rajendra Pachauri from United Nations Intergovernmental Panel on Climate Change says people should eat less meat to control their carbon footprints. ‘We haven’t come to grips with agricultural emissions’.

Nearly two-thirds of U.S. adults get at least minimum physical activity, according to new, less strict guidelines announced last October. Under the older guidelines, fewer than half of adult Americans would have been “physically active,” the CDC calculates. What an ‘easy’ intervention ;-)
Fødevareindustrien arbejder ihærdig på at få indført GDA som nyt ernæringsmærke. Men mærket er misvisende. Derfor har Forbrugerrådet nu anmeldt tre produkter for vildledende mærkning: Knorr Organic Mix, KiMs Snack Chips – Supersprøde med krydderi og Daloon Shoo Van Forårsruller.
