Trans fats are uniquely unhealthy  One of the purposes of government is identify possible threats to health and protect the people from these threats. The fact that some government regulations seem 'silly' or misplaced, or cannot easily be understood by lay-people is not a compelling argument for having no regulations at all, or for not having regulations in the case of trans fat. The commentators who denounce the 'nanny state' do not indicate what, if any, regulations or styles of regulation they approve of. Do they think there should be no inspections of restaurants by health inspectors? No regulation at all of food or drug safety by the Food and Drug Administration? Some commentators think that people should be encouraged to study the dangers of trans fats and make their own judgements about what to eat. But people have limited time to do research on such matters. It makes sense to delegate the research to a central authority, so that instead of 300 million people trying to learn about trans fats and every other lurking menace, a handful of experts can make recommendations based on the likely responses and desires of the average, informed citizen.  Non-specialists’ capacity to absorb information on complex chemical and biological subjects is quite limited. The majority of us are reliant on the research of others for most of what we know.(5) The opinion of the experts on the dangers of trans fats is conclusive: trans fats are unsafe.  The American Food and Drug Administration (FDA) considers all uses of trans fats to be 'generally regarded as safe.' This allows the use of trans fats in whatever way food producers desire. ’Safe’ for the FDA means 'a reasonable certainty in the minds of competent scientists that the substance is not harmful under its intended conditions of use', which no longer applies to trans fats. This 'generally regarded as safe' status should be revoked which in turn would greatly restrict its use in food.  The other option would be to allow local jurisdictions to regulate trans fats, but this would be more costly and lead to a patchwork of regulations.(1) The most effective method of controlling the use of trans-fats is through centralised, nationally applicable policy making. The poor and young are particularly vulnerable to the negative health effects of trans fats; at the very least, the threat posed to these groups justifies the use of informed regulation. Professor Alan Maryon-Davis, president of the UK Faculty of Public Health said in 2010: "There are great differences in the amount of trans-fats consumed by different people and we are particularly concerned about young people and those with little disposable income who eat a lot of this type of food. This is a major health inequalities issue.”(6)  The government has a legitimate interest in protecting its citizens from harms that they are not best placed to understand or avoid themselves, and so a ban on trans fats would not only save lives but would also be legitimate under the government's role to protect when citizens cannot reasonably protect themselves.
