Do trans-fat bans save lives?
Brandon Restrepo, Matthias Rieger 16 July 2014
Artificial trans fat is omnipresent in the global food chain, but the medical consensus is that it increases the risk of developing cardiovascular diseases such as heart disease and stroke. Between 2007 and 2011, New York City and six other county health departments implemented bans on trans fat in restaurants. This column presents the first evaluation of the effect of these bans on cardiovascular disease mortality rates.
The use of artificial trans fat or partially hydrogenated oil – which is industrially produced by adding hydrogen gas to liquid vegetable oil – is widespread across the world’s food production chains and service industries. Aside from the fact that it has the same caloric value as any other fat, there are no known health benefits to consuming artificial trans fat. The food industry prefers using trans-fat-containing oils to healthier oils because it is cheap, it increases the shelf life of food products, it promotes flavour stability, and it improves the texture of food.

Are fruit and vegetables good for your mental health as well as your physical health?
Sarah Stewart-Brown 11 November 2012
Eating fruit and vegetables could be good for your mental health. This column explores the evidence, arguing that better surveys need to be carried out if we are to accurately establish causality. If we can understand how mental health is linked to diet, the benefits to the public – and those who decide public policy – could be huge.
Public health policy has an enormous impact on national wellbeing (Delaney, Smith and McGovern 2011). A study recently published in Social Indicators Research (Blanchflower, Oswald and Stewart-Brown 2012) investigated the relationship between fruit and vegetable consumption and mental health. The study drew upon three robust, representative, cross-sectional studies of random samples of adults in three UK countries; England, Scotland, and Wales. Each of these surveys gathered self-reported intake data, measured in portions of fruit and vegetables of up to eight or more a day.
