Studies generally: • Define sustainability in environmental terms (often just GHGs) • Are rich-world focused • Ignore wider socio-economic context • Don’t consider other determinants of nutritional status • Don’t consider non-nutritional health implications of food And so, with these (enormous) provisos, can we define Good-enough / interim /partial Principles of environmentally sustainable and nutritious diets? • Diversity – a wide variety of foods eaten • In energy balance • Based around: tubers and whole grains (but not rice); legumes; fruits and vegetables - field grown and robust • Meat eaten sparingly if at all - all animal parts consumed • Dairy products or fortified plant-substitutes eaten in moderation & other calcium-containing foods consumed • Unsalted seeds and nuts included • Some fish and aquatic products sourced from certified fisheries, although less frequently than Eatwell advises • Limited consumption of sugary and fatty sweets, chocolates, snacks and beverages • Tap water in preference to other beverages Health & environment: an arranged marriage, not a love match Sustainable but unhealthy Healthy and sustainable • Mainly grains (except rice), tubers and legumes • low in nutrient rich foods including fruits, vegetables and animal products • Low waste and energy but high risk storage and cooking practices • Low in animal products • Low in processed sugary foods • High in robust, field grown, seasonal vegetables & fruits • Rich in legumes and moderate in nuts • Occasionally fish from certified stocks • Food purchased is not wasted and cooked efficiently Unsustainable and unhealthy Healthy but unsustainable • • • • • Moderate levels of lean meats • High levels of resource intensive vegetables and fruits (eg. air freighted produce and 'ratatouille' vegetables and salads produced out of season • Fish consumed from unsustainable stocks • High dependence on chilled produce • Inefficient cooking methods and high levels of waste High in animal products Low in vegetables and fruits Low in grains and tubers High in energy and fat dense, nutrient poor processed foods • High levels of food waste and inefficient cooking methods Making change happen An amateur’s personal view on food and its meanings Nurture Guilt Entertainment Neurosis Pleasure Need Ritual Food Habit Social glue Satisfaction Love Status Power Comfort Bribery Religious significance Time-pass The meat issue.

Cheap intensive meat Nutrition? Low fat, grassfed Taste? Whose taste? Waste minimisation? Sausages, pasties & nuggets Better for what? Resource efficiency? Extensive ruminants 2-for-1? Dairy cattle beef as byproduct Landscape & aesthetics? Go for grazing GHG emissions? Intensive battery chickens Employment? Need to look along whole supply chain Animal welfare? (Probably) go for freerange Thinking about behaviour change / practice / consumption Things that get said Academics : nutrition, environment, ag Subsidies economics, international Choice architecture development Viral marketing Standards Consumption taxes Changed consumption Labelling Food industry AW, envt, health NGOs Bans Production taxes Rationing Planning policies Education Mandatory Procurement reporting policies Think tanks Ways of approaching the issue Influenced by: • Ideologies & values • Disciplinary training • Sectoral lens Categorisation lens Example Actor (ie. change agent) eg. Farmers, food industry, media, public institutions, social network/group (eg. transition towns group, weight-watcher group) national, international and local level policy makers) Target group (ie. group whose behaviour is to be changed) Value frame eg. Food producers, food manufacturers and retailers, and eaters (defined variously as individuals, families, consumers, citizens) Space & place eg. Place of production - farm, factory; place of retail - shops; place of consumption - canteens, restaurants, home; place of confinement schools, offices, hospitals, prisons; journey to work; location of food provision Timing - life course eg. Life stage - starting school, pregnancy, marriage, retirement Timing - eating occasion eg. Breakfast, lunch, dinner, snacks, celebration meals, on the go eating Intervention theory eg. 4Ps of marketing theory, Defra’s 4 Es framework, Michie and West behaviour change wheel, Nuffield Ladder, Nudge Transparency to end consumer eg. Product reformulation (where the consumer may not even realise they are consuming differently) through to rationing Coerciveness eg. Education, pricing changes, regulation eg. Health, environment, animal welfare, coolness, parental instincts; or more generally: intrinsic values versus extrinsic motivations, altruism versus self interest; citizen vs consumer; individual fulfilment versus societal goals Intervention type Education, information & awareness raising and social marketing Example Actors* Product labelling, media, viral marketing, teaching; meat free Mondays Food industry Producers; NGOs, media, food industry teachers; journalists dieticians Transition Towns Changing the choice architecture Gondola aisle offers & Food industry store layout, canteen layouts, opt-ins; vegetarian meal deals Individuals; catering buyers? Shops, conferences, restaurants etc. Enabling & supporting Support groups Transition Towns increasing range of vegetarian foods in catering outlets; meat free Mondays Employers, voluntary organisations, public institutions Individuals; catering sector work places, schools, community centres, health centres etc. Fiscal measures (producer & consumer focused) including pricing production & Government; consumption food industry incentives/disincentive s; personal carbon budgeting. Carbon trading Food producers (farmers); individuals Will influence perceived costs of legitimacy production and important price of food in stores, restaurants etc. Regulation & legislation (producer & Public procurement Government specs; rationing; bans; emission caps; planning Food producers, retailers and May be introduced at local Target group Context Value frame Timing SMs, intrinsic and life stages, workplaces, extrinsic eating restaurants etc occasions community & health centres, times when people are at their most unreflective Will depend upon approach taken perceived legitimacy important life stages; pressure points A hypothetical example in a SM context Replace Greater provision of vegetarian meals, promotion of fruit and vegetables, meat substitutes (e.g. veggie burgers) Reduce Adjusting portion sizes of carcass meat or in ready meals Reformulate Increasing the veg: meat ratio in composite meals Rebrand Promoting or refreshing products that are already vegetarian Respect Meat as a ‘Sunday-special’ or celebration food; promoting ‘nose to tail’ eating; “meat as flavouring/garnish.” Reprice Making vegetarian alternatives more attractive to shoppers Thinking about interventions also need to bear in mind • Cross-transferability from other areas (eg. how far are successful interventions wrt drugs or driving applicable to food?) • Risk of perverse side effects Intervention effect Change in practice People eat less meat but more refined, processed Doughnut effect carbohydrates Blueberry effect Sausages effect People eat less meat but more high impact fruits & vegetables Higher meat prices cause people to cut down on their meat spending but maintain quantity by eating less healthy meats such as sausages or fatty mince. Outcome Lower GHGs but poor nutritionally and other environmental downsides Possibly good for health but potentially higher GHGs The impacts on GHGs are unclear; there will be benefits for resource efficiency; impact on health poor Red to white effect GHG oriented policies cause people to shift from red meat to white Reduced GHGs, impacts on health and other environment mixed; potentially negative for AW Meat-shoring effect Higher meat prices lead to increased spending on meat (maintaining consumption) but reduced intakes of fruit and vegetables Negative outcomes for health and for the environment. Welfare effect People maintain their levels of meat consumption but The impacts on the environment will be mixed, impacts on health may be neutral or negative, buy lower welfare meat instead. impacts on welfare across many (not all) welfare indicators poor Halo effect People shift to a more sustainable diet but feel justified in buying that new iPad or flying off on holiday. Impacts on health positive, impacts on environment depend on the substitute consumption practice Leaky system effect People in the UK consume a more sustainable diet but No net benefit - impact swapping farmers increase exports; or UK reduce production but meat imports increase Employment effect People eat a more sustainable diet; livestock farmers go out of business and either remain unemployed or are employed in other sectors Net health & environment impacts depend on a. health impacts of employment changes b. environmental impacts of substitute activity. Workshop aims • • • • • What do we know? What don’t we know? Where do we know enough to justify action now? Where is more understanding is needed? What sort of research would help improve the evidence base needed for effective policy making? • Can we put all that in writing by the end of tomorrow? Thank you www.fcrn.org.uk
