Shops and Restaurants Make the Path to Sustainable Diets – Here’s How
Along with measures like higher taxes and marketing restrictions on unhealthy products. Available interventions have the potential to contribute to population health and unrealistic goals. But they are still largely ignored by policymakers.
They therefore set out to summarize the evidence supporting available interventions in a form useful to policymakers.
They searched the scientific literature and identified nine real-world studies (including four new) that showed consistent and often significant effects of available interventions on consumers’ choice of healthier or more sustainable options, with no evidence of adverse effects, including an increase in health inequality.
For example, increasing the percentage of vegetarian meal options in a cafe from 25% to 50% reduced the rate of choosing a meat meal by almost eight percentage points (from 81% to 73%).
The same, similar, increasing the proportion of lower energy food options available in cafeterias from 42% to 50% reduced calories purchased per transaction by almost 5% from baseline (from 384 to 366 kcal).
And early results from a study of online supermarket purchases show that reducing the percentage of alcoholic beverages from 75% to 50% and 25% increases the percentage of non-alcoholic beer and wine and water. beverage selection from 24% to 32% and 45% respectively.
Some uncertainties, such as whether these findings are applicable to low- and middle-income countries, and the impact of population preferences (social norms) on what we eat.
Challenges that may have contributed to these interventions being relatively overlooked, such as incongruity with prominent public discussions around individual responsibility for maladaptive behaviour. and the resistance of businesses for fear of losing revenue needs to be taken into account.
