ScienceDaily reports three interesting studies relevant for designing a public health policy. As we have stated previously, public policy should focus on prevention of disease – also known as health promotion.
The first one, Eating healthy at work matters, shows that people who buy unhealthy food at work have in general also more unhealthy lifestyles. This study suggests that employer-sponsored health programs could improve employee health. Of course, there’s the direction problem: do people bring their lifestyle to work or is it the other way around?
The second study, Economists find net benefit in soda tax, argues that a tax on sugary drinks will have a net benefit to society. The overall benefits, according to the article, outweigh the costs of a sugar tax. Importantly the researchers stress that a soda tax should be based upon on sugar content (e.g. ten cents per gram of sugar).
A third study, we like to mention here, has found a correlation between the consumption of unsalted tomato juice and a decreased risk of heart disease. Needless to say, correlation does not equal causation and hence more research is required, but it is an interesting result as tomato juice is relatively cheap.
