The case for agri-tech in public health

The public health problem: Over one in four adults are obese, with an additional 36% classified as overweight in England. The prevalence of obesity has been steadily rising since 1993, with little evidence to suggest this trend is slowing. This is not solely an adult issue. The sharpest increases in obesity have recently been observed among children. Currently, 15% of children aged 2 to 15 are obese, and a further 27% are overweight. Projections from the Royal Society of Public Health suggest the situation will get worse. 39% of children are expected to be obese or overweight by 2029–30, rising to 41% by 2034–35.

The cost: The government estimates that obesity is costing the NHS £11.4bn a year and is the root cause of diabetes and heart disease and the second biggest preventable cause of cancer after tobacco smoking. Less conservative estimates that account for wider consequences suggest that poor diets cost the UK £126bn a year. There is a strong rationale for public health intervention and the Labour government is demonstrating a willingness to intervene. One of health secretary Wes Streeting’s big three healthcare shifts set out in this week’s NHS 10 Year Plan is a shift from treatment to prevention, and for public health this means intervention.

Government action: Trailing the publication of the NHS 10 Year Plan alongside an obesity strategy, the government has announced a new standard for food retailers to make the average shopping backet of goods healthier. Big food businesses will be required to report on healthy food sales and will be overseen by the Food Strategy Advisory Board. This builds on a government consultation launched in May on plans to tighten the sugar levy by reducing the minimum sugar content level from 5g to 4g and remove the exemption for milk-based drinks. This signals a clear appetite within government for more interventionist policies. Such an approach will undoubtedly incur backlash from anti-nanny state politicos and big industry actors. However, it also creates an opportunity for innovators.

Agri-tech innovators: A contested political environment driven by a firmer stance on obesity and healthy foods by ministers, creates a window for pragmatic, science-driven solutions. Crop biofortification to increase the nutritional profile of foods. Precision fermentation to produce low-fat dairy and bioactive compounds. Modified starches with a lower glycaemic index. The agri-tech sector is well-placed to engage and support the government to achieving public health outcomes. Junk food advertisement bans might grab the political headlines, but ministers will need solutions that measurably change health outcomes and improve the health of the nation.

What next: The NHS 10 Year Plan and the obesity strategy will feed into Defra’s set piece item due for publication later this year: the national food strategy. Broadening access to healthy foods dominates the political discourse around this food strategy. Improving public health and tackling obesity have shot up the political agenda and joining this up with food and farming policy is the key to successfully achieving these policy aims. Aligning with the government’s thinking and offering solutions to public health priorities will strengthen the agri-tech sector’s positions to shape policy and work alongside ministers and policymakers.
