There is considerable debate about whether governments should make healthy food more affordable through subsidies or discourage unhealthy eating by imposing higher taxes on unhealthy products. While subsidising nutritious food can make healthier choices more accessible, I believe taxation is ultimately more effective because it directly addresses the excessive consumption of unhealthy products.
On the one hand, subsidising fruits and vegetables can encourage people to consume a healthier diet. In many countries, nutritious food is relatively expensive, particularly for low-income households. Reducing its price would therefore allow more people to purchase fresh produce regularly. This could be especially beneficial for families with limited disposable income, who may otherwise rely on cheaper processed foods. Furthermore, lower prices could make healthy food more competitive with unhealthy alternatives, potentially encouraging consumers to change their eating habits without restricting their freedom of choice.
On the other hand, taxing unhealthy food may be a more effective way of changing consumer behaviour. The main advantage of this approach is that it increases the financial cost of products that are high in sugar, salt and unhealthy fats. As a result, consumers may reconsider purchasing these items, particularly when cheaper alternatives are available. Such taxation could also discourage manufacturers from producing excessively unhealthy products and encourage them to reformulate their goods. In addition, revenue generated from these taxes could be invested in public-health programmes or used to subsidise healthier foods.
In my view, although food subsidies can improve access to nutritious products, taxation is likely to have a greater long-term impact. Making healthy food cheaper does not necessarily persuade consumers to choose it, as many people are attracted to unhealthy products because of their taste and convenience. By contrast, taxation directly reduces the attractiveness of unhealthy choices while generating revenue that can be used to support healthier alternatives.
In conclusion, subsidising fruits and vegetables can make nutritious food more accessible, whereas taxing unhealthy products can discourage excessive consumption. I believe a combination of both policies would be ideal, but taxation should play the central role because it addresses the demand for unhealthy food more directly.
