1 Lessons from the LIPGENE Project: Economic Issues in Producing and Supplying Special Lipid- Modified Foods Presentation for Munich Conference December 2005 By Dr James Fry and Dr Willa Finley LMC International, Oxford, UK

2 Outline of the Presentation Brief summary of the incidence and economic costs of obesity in the EU. The costs of devising separate identitypreserved (IP) output and processing chains to supply foods with an improved lipid content to help to combat the metabolic syndrome in particular and obesity in general. The willingness of consumers to pay a premium for healthy foods, and the case for subsidies to lower the prices of such food and lower the incidence of obesity.

3 The Incidence and Direct and Indirect Costs of Obesity in the EU-15 (Applying growth rates from OECD time series some of which are biased downwards by self-reporting to International Obesity Task Force estimates, and UK National Audit Office obesity cost data for 1998)

7 Overall Costs and Incidence of Obesity in 2002 in the EU-15 The full annual direct and indirect costs of obesity in the EU-15 in 2002 were estimated to be nearly 33 billion. The UK, Germany, Italy and France together accounted for over 75% of the total. For both men and women, at least half the member states have more than 20% of their adults with BMIs of over 30.

8 The Costs of Improving Plant, Dairy and Meat Nutrient Profiles and of Applying Identity Preservation (IP) Systems Throughout Their Supply Chain

9 The Costs of Separate Supply Chains Identity preservation (IP) systems are needed to keep special foods, commanding premium prices, separate and segregated from cheaper commodity products. In addition to the costs of devising special IP systems for special plant and animal products, the creation of low volume supply chains imposes extra costs on suppliers via the inability to exploit economies of scale.

16 1.6 Levels of CLA in Conventional and Enhanced Milk and Beef CLA Content, grams/100 grams Beef CLA-enhanced Conventional Milk

17 Production Costs of Food Products with Healthy Nutrient Profiles Total supply costs for milk, meat or eggs with healthy nutrient profiles are 10-60% more than for conventional alternatives. This is due to The extra costs of feed, such as flax (linseed) or fish oil, needed to enhance the CLA/ Ω-3 levels, The costs associated with reduced rate of gain (high CLA beef) or reduced productivity (Ω-3 eggs). IP costs, including transportation and testing. Higher unit costs due to inability to exploit scale.

31 Overall Extra IP and Input Costs for Healthy Foods, From Farm to Retail IP costs are 2-5% of costs across all products. Extra costs due to the healthy trait typically account for 7-14% of total costs. Combined IP and special input costs represent 10-16% of total costs throughout the chain. It is noteworthy that combined IP and extra input costs in animal food products, as a share of total costs, are broadly similar to the IP costs of oilseeds with speciality fatty acid profiles.

32 Economies of Scale Have the Biggest Impact Upon Overall Costs Economies of scale in agriculture, processing, distribution and retailing have a bigger effect upon total costs than IP and higher input costs. The cost penalty for niche products (with 2-3% of the market) vis-à-vis conventional products (with over 90%) varies from 35% to 85% for the products considered in the LIPGENE project. Also, retailers expect higher margins on slowmoving niche products than on basic foods.

33 Implications for LIPGENE Using these results, one can link the extra cost of supplying fat-modified foods to (a) the nature of the product (plant oils, meat or eggs) and (b) the output scale of the healthy product. The scale of output, in turn, depends upon (a) consumers willingness to pay price premia for health and (b) subsidies, if any, offered to encourage consumption. Therefore, we now turn to consider the evidence about consumers willingness to pay.

34 The Willingness of Consumers to Pay Premia for Perceived Health Benefits: The Trade-off Between Price Premia and Sales

42 Present Market Share of Healthy Foods Phytosterol spreads have 7% of the market in the UK, and 2%-3% in the US, with buyers paying a near 300% premium at retailers. Healthy eggs and chickens have 3%-4% of the US market, with premia of close to 200% for eggs, but of only 40% for fresh chickens. Healthy beef, milk and cheese hold less than 1% of the US market and command price premia of 25%, 60% and 115%, respectively.

43 The Policy Dilemma Balancing Subsidies for Healthy Food Consumption against Potential Savings in Obesity-Related Health Costs

44 Policy Dilemma Only a few consumers will pay a significant premium for special food attributes. The challenge is to balance a. The cost of measures to boost demand for healthy foods, thus expanding the scale of output (and lowering production and IP costs at the same time) against a. The benefits from reductions in obesity and the consequent savings in health costs.

45 Policy Options 1. One option would be to subsidise the costs of inputs to healthy foodstuffs to make them attractive to consumers on cost grounds. 2. Another option is to mandate the use of healthy inputs in foodstuffs and thereby force consumers to meet the extra cost. 3. A third option is to target subsidies to specific users, e.g., via vouchers, much like medical prescriptions.

46 Problems of These Options Problems of These Options Subsidising inputs across the board ensures take-up, but it is indiscriminate in scope and wasteful in failing to target beneficiaries. Mandating input use (as with vitamin A in sugar in some countries) is indiscriminate, too, but spares governments subsidy costs, instead passing them on to consumers. Targeting subsidies via vouchers avoids such waste, but (a) entails additional administrative costs, (b) incurs cost penalties from lack of scale, while (c) risking failing to reach many of the beneficiaries from such intervention.

49 Cost-Benefit Analysis: Options 1 and 2 We have computed the cost of subsidies on inputs such as phytosterols and linseed and fish oils for all EU soft spread, poultry and beef output, so as to bring retail prices of healthy foods just below those for conventional foods. (N.B. This would cut out the costs of separate supply chains and IP, since healthy products would become the commodity products.) These costs are contrasted with the costs of obesity to reveal their relative magnitudes.

50 Costs of Subsidising Inputs on All Output vs. the Direct and Indirect Costs of Obesity Annual Costs, billion Special Inputs Obesity Costs Eggs Broilers Beef Spreads Costs of Obesity

51 Evidence of the Benefits from Lipid-Modified Diets Indications of benefits from a more general approach to altering the balance of lipids are provided by Vessby at al, Changing diets to monounsaturated from saturated fats improved insulin action by more than 20% and led to a better lipid profile, as long as individual s overall fat intake was less than 37% of their total calorie intake. Beyond that percentage, dietary changes had no effect.

52 The Trade-off Options 1 & 2 In these two options (full subsidisation or mandating), everyone receives lipid-modified animal products, regardless of their health. Our costings assume big increases are possible in the use of key inputs without bidding up their prices. However, against this, these options have the benefit of avoiding all IP costs and ensuring the attainment of economies of scale. The result is that the costs of an EU-wide system to promote a healthier lipid profile in leading animal-derived foods would amount to 30% of the direct and indirect costs of obesity.

53 Costs of Targeting Input Subsidies on 5%, 20% and 100% of the EU Population Extra Costs, billion/year % 20% 100% Share of Product Market Targeted for Subsidies or Mandating IP and Lack of Scale Special Inputs

54 The Trade-off Option 3 Here we consider the effect of targeting subsidies on 5% and 20% of the population, rather than 100%, in terms of the associated IP costs and lack of economies of scale, setting these against the savings on special input costs. By chance, the combined additional costs of lack of scale and IP systems are similar for both the 5% and 20% cases, at roughly 4 billion. Extra costs of special inputs bring the net costs to around 5 billion for the 5% case and 6 billion for 20%, vs. 10 billion for 100% scope.

55 Implications for Public and Private Sector Responses

56 Implications for Policy Without some form of intervention, it seems inevitable that the combination of high input costs, IP systems and lack of scale, alongside consumers unwillingness to pay much of a premium for healthy products, would condemn healthy lipid-modified foods to a series of mostly small niches in the overall market. If governments intervene, they must decide whether a targeted approach towards subsidies offers a better cost-benefit trade-off than universal subsidisation or mandating.

57 Targeting or Global Intervention? Targeting subsidies proves to be cheaper than an across-the-board subsidy, as long as the administrative costs are kept in check. A further factor favouring a targeted approach is that it runs less risk of bidding up the prices of special ingredients for lipid-modified food products than a comprehensive approach. We must await results from LIPGENE research before the potential scale of reductions in the incidence of the metabolic syndrome as a result of lipid modification become clear.

58 Scope for Private Initiatives? A notable development in 2005 was the launch of a scheme of vouchers by a Dutch health insurance company for its clients judged to be at risk of cardiovascular disease. These vouchers provide a subsidy of 40 per annum towards purchases of phytosterol spreads. An identical scheme has now been launched in France, but has attracted formal complaints from consumer groups because of the commercial link between the subsidy and a particular company s food product.

59 Cost-Benefit Conclusions The analysis presented here suggests: If the targeting is directed towards lipid-modified animal products, ranging from meat to dairy products to eggs, for the 20% of the EU population who are obese, the subsidy needed to cover all increased product costs would be 6 billion/year. If this approach manages to reduce the incidence of obesity by one fifth, i.e., from 20% to 16%, the overall annual costs of obesity would be lowered by over 6 billion, yielding a small net advantage. The trade-offs will only become better defined as the LIPGENE project generates scientific results.
