The study found that there is no central public record or compulsory national system to monitor compliance with government School Food Standards in England; caterers and schools largely self-assess their own compliance. ^[1] Dr Will Tullett, a historian of smells at the University of York, said children should be educated in smelling aromas, suggesting it could improve wellbeing and help them understand the world around them. ^[2] Lead author Dr. Nicola Nixon of the University of York's Department of Health Sciences said school meals represent a powerful lever to tackle the child health and obesity crisis, yet the current system is 'fragmented, opaque and largely unmonitored', and called for greater transparency, national oversight, and collaboration between schools, caterers, and public health teams. ^[3] More than 20% of Yorkshire primary schools (372 schools) do not have the 150 pupils required to reach the financial break-even point for a school meal service. ^[4] The study found that local authority caterers serve the majority of smaller, rural and economically challenging schools where meal provision often runs at a loss, while commercial caterers predominantly serve larger, urban schools with higher pupil headcounts. ^[5] Tullett said pollution has been found to impair people's olfactory abilities, and that many objects and substances from margarines to car interiors have been stripped of their original smells and re-odourised synthetic, raising an open question about what that does to our ability to discriminate between different smells. ^[6] Tullett said that smells and our ability to enjoy them are crucially linked to our sense of wellbeing, and that those who suffer from smell loss often experience depression, anxiety, and other symptoms, and that smelling can help with food safety such as judging if something is fresh instead of relying solely on a use-by date. ^[7] Tullett said the more we smell, the more we enlarge the vocabulary through which we can describe other things, citing sommeliers who walk around them smelling everything to expand their range based on reference points. ^[8]
