Two tools for putting
direct financial value on what are otherwise societal costs are regulation and
taxes. One example are taxes on sugar which seek to reflect some of the societal
cost incurred by obesity: In France beverages with added sugar or sweetener
have been subject to an excise duty since 2012 and added sugar in soft drinks
has been taxed as part of the Public Health Product Tax in Hungary since 2011 [1, p. 18f].
The effects of these
taxes were firstly the desired decrease in consumption. The Mexican soda tax led to a decrease of purchase of sugary drinks by 12% in the first year and most importantly, the biggest reductions have occurred among the poor [1].
On the other hand, profitability stayed mostly
stable. However, in some case cases profitability also de- or increased [2, p. 30ff] – an indication that price sensitivities vary across products and
brands. Thus, taxes appear to not be suitable universal tool. It can be useful
to shift buying patterns for commodities, e.g. from cooking oils high in
saturated fats to those lower in these fats, but consumers will continue to
purchase what they consider indulgences, such as chocolates or high end ice
cream, with a certain indifference to the price. Also the introduction of food
taxes is highly controversial and usually limited to a small set of food
products. In Hungary only 8% of the average total energy intake of an adult
women come from added sugars in the taxed product groups (chocolate, sweets,
soft drinks) [2, p. 46]. Added sugars in other common product groups such as cakes, biscuits,
ice cream, preserves, condiments or fruit yoghurts are currently not subject to
the tax. The difficulties in deciding where to draw the line highlight one of
the key weaknesses of using taxes as a key policy option.
However, another
important effect of these food taxes are that they accelerate reformulations
already partially under way to respond to consumer demands for “lighter” or
healthier products. An impact assessment of the Hungarian Public Health Product
Tax found that 40% of manufactures reformulated their products. Of the
reformulations, 30% completely removed the targeted ingredient and 70% reduced
its quantities [3, p. 32]. However, the same effect can be obtained by setting clear standards
and thereby creating a market for healthy: The Dutch Choices Foundation (cf. p.
7) was able to show that most products carrying their logo have been
reformulated to meet their criteria, for example by reducing added sugar in
sauces. Furthermore, new products specifically formulated to meet the choices
criteria were developed following the launch of the logo [3, p. 10].
