When Industrial Policies Conflict With Population Health: Potential Impact of Removing Food Subsidies on Obesity Rates.

OBJECTIVES: To model the potential impact on obesity of removing butter, cheese, and sugar subsidies in the Canary Islands. METHODS: A simulation model was applied based on a local data set of subsidies and retail prices (2007-2016), data on own-price elasticity estimates, and representative nutritional and health surveys. We estimated marginal obesity prevalence and population attributable fraction to assess the potential impact of the butter, cheese, and sugar subsidies intervention. RESULTS: The intervention was predicted to avoid 10 363 obese adults over the study period, because of the reduction of the obesity prevalence by -0.7 percentage points. Overall, the predicted effect was largest in elderly and male groups, although females with a low socioeconomic status experienced the greatest decrease in the prevalence. The population attributable fraction predicted that 4.0% of population with obesity were attributable to the existence of these subsidies. CONCLUSIONS: This analysis provides policy makers with the predicted impact on obesity of the butter, cheese, and sugar subsidies disposal, enabling them to incorporate this health impact into decision making across policy areas in the economic and health field. This study aims to model the potential impact on obesity of removing industrial subsidies for butter, cheese and sugar in the Canary Islands.

Short communication: Effect of carbon emission trading on European Union butter prices.

Since its inception, the European Union (EU) carbon emission market has been vastly successful in reducing greenhouse gas emissions. Accordingly, the usage of environmentally friendly fuels (e.g., ethanol, biodiesel) has increased significantly over the last few years. Given that EU biodiesel is mainly produced from rapeseed oil and soybean oil, higher carbon taxes are likely to increase the demand of these important vegetable oils, which further affects the prices of its close substitute such as butter. Nevertheless, the association between the EU emission trading scheme and butter prices remains understudied. In this paper, we aim to fill this vacuum in the existing literature. Applying the autoregressive distributed lag bound testing procedure, we show that emission market seems to have a long-term effect on EU butter prices, implying that changes in the levels of carbon taxes will lead to changes in the price level of butter. These results are of vital importance to policymakers and investors.

High concentrations of furan fatty acids in organic butter samples from the German market.

Furan fatty acids (F-acids) are valuable antioxidants containing a furan moiety in the central part of the molecule. They occur in the lipids of different foodstuffs and plants, with grass being the main source for their presence in milk fat and butter. Because cows from organic farming receive higher portions of grass-based feed, it was tested whether organic butter samples (n = 26) contain more F-acids than conventional ones (n = 25) in Germany. For this purpose, samples were melted, and the lipid phase was separated and transesterified into methyl esters, which were enriched using silver ion chromatography and analyzed by GC-EI/MS in the selected ion monitoring (SIM) mode. Levels of F-acids in butter were higher in summer than in winter, and in both seasons, organic samples contained significantly higher levels of F-acids than conventional ones (one-way ANOVA: p < 0.001). Furthermore, the daily intake of F-acids via milk fat and other foodstuffs was calculated.

New series for agricultural prices in London, 1770­1914.

New annual series for the prices of major agricultural commodities sold in London markets between 1770 and 1914 are presented. These series are based on bimonthly observations drawn from newspaper market reports. The products covered are wheat, barley (grinding and malting), oats, potatoes, hay, butter, beef, mutton, and pork. Annual prices are calculated for both calendar and production years. The new series are compared to existing series.

Development and application of a processing model for the Irish dairy industry.

A processing-sector model was developed that simulates (i) milk collection, (ii) standardization, and (iii) product manufacture. The model estimates the product yield, net milk value, and component values of milk based on milk quantity, composition, product portfolio, and product values. Product specifications of cheese, butter, skim and whole milk powders, liquid milk, and casein are met through milk separation followed by reconstitution in appropriate proportions. Excess cream or skim milk are used in other product manufacture. Volume-related costs, including milk collection, standardization, and processing costs, and product-related costs, including processing costs per tonne, packaging, storage, distribution, and marketing, are quantified. Operating costs, incurred irrespective of milk received and processing activities, are included in the model on a fixed-rate basis. The net milk value is estimated as sale value less total costs. The component values of fat and protein were estimated from net milk value using the marginal rate of technical substitution. Two product portfolio scenarios were examined: scenario 1 was representative of the Irish product mix in 2000, in which 27, 39, 13, and 21% of the milk pool was processed into cheese (€ 3,291.33/t), butter (€ 2,766.33/t), whole milk powder (€ 2,453.33/t), and skim milk powder (€ 2,017.00/t), respectively, and scenario 2 was representative of the 2008 product mix, in which 43, 30, 14, and 13% was processed into cheese, butter, whole milk powder, and skim milk powder, respectively, and sold at the same market prices. Within both scenarios 3 milk compositions were considered, which were representative of (i) typical Irish Holstein-Friesian, (ii) Jersey, and (iii) the New Zealand strain of Holstein-Friesian, each of which had differing milk constituents. The effect each milk composition had on product yield, processing costs, total revenue, component values of milk, and the net value of milk was examined. The value per liter of milk in scenario 1 was 24.8, 30.8, and 27.4 cents for Irish Holstein-Friesian, Jersey, and New Zealand strain of Holstein-Friesian milk, respectively. In scenario 2 the value per liter of milk was 26.1, 32.6, and 28.9 cents for Irish Holstein-Friesian, Jersey, and New Zealand strain of Holstein-Friesian milk, respectively.

2006 marketplace survey of trans-fatty acid content of margarines and butters, cookies and snack cakes, and savory snacks.

In recent years, newer technologies have been developed to reduce the trans-fat content of fats and oils used in manufacturing food products. To examine the implications of these changes on foods in the marketplace, a survey was conducted to assess current levels of trans and saturated fat in three food categories: margarines and butters; cookies and snack cakes; and savory snacks. A sampling of products from each category was conducted at a Wal-Mart Supercenter in the Minneapolis-St Paul, MN, metropolitan area in July of 2006. All information was obtained from product labels, except price, which was recorded from price listings on product shelving. Most margarines and butters (21 of 29), cookies and snack cakes (34 of 44), and savory snacks (31 of 40) were labeled as containing 0 g trans fat. However, some products contained substantial amounts of trans fat. Most notably, 3 of 40 savory snack products were labeled as containing > or =3 g trans fat. Significant inverse correlations were found between product price and the saturated and trans-fat content of margarines (r=-0.45) and savory snacks (r=-0.32). In conclusion, it appears that the food industry has made progress in reducing the trans-fat content in a variety of products. Nonetheless, consumers need to read product labels because the trans-fat content of individual products can vary considerably. Products that are lower in trans and saturated fat tend to cost more, which may be a barrier to their purchase for price-conscious consumers.

Effects of selection and crossbreeding strategies on industry profit in the New Zealand dairy industry.

The effects of selection and crossbreeding on the New Zealand dairy industry net income were evaluated with a deterministic model over a 25 yr planning horizon. Several mating strategies involving Holstein-Friesian, Jersey and Ayrshire cattle were evaluated. These strategies were straight breeding, upgrading to Holstein-Friesian, upgrading to Jersey, upgrading to Ayrshire, use of the best bulls irrespective of breed and two- and three-breed rotational crossbreeding. Industry productions of milk, fat, protein, and lactose were calculated assuming that 12,000 kg of dry matter per hectare was utilized from 1,224,911 hectares of pasture. Profitability was the difference between income (international sale of whole milk powder, casein, butter, and beef from salvage animals) and costs (farm expenses, milk collection, manufacture, and marketing). Casein and whole milk powder were valued at NZ$8.345 and NZ$3.306/ per kilogram, respectively, over 25 yr. Butter was valued at NZ$2.995/kilogram for base year production levels and NZ$0.45/kilogram for marginal increases in production. Upgrading to Holstein-Friesian resulted in the highest industry net income (NZ$1119 million) followed by straight breeding (NZ$1086 million) and two-breed rotational Holstein-Friesian x Jersey (NZ$1076 million). However, if the marginal value of extra butter production was assumed equal to the average base value, then upgrading to Jersey resulted in the highest industry net income (NZ$1185 million) followed by two-breed rotational Holstein-Friesian x Jersey (NZ$1177 million) and use of the best bulls (NZ$1173 million). Future costs and prices of dairy products have major impact on mating strategies.
