Structural responses to the obesity epidemic in Latin America: what are the next steps for food and physical activity policies?

Obesity is among the most complex public health challenges, particularly in Latin America, where obesity rates have increased faster than in any other region. Many countries have proposed or enacted comprehensive policies to promote adequate diet and physical activity under a structural framework. We summarize articles discussing the scope and impact of recently implemented obesity-related interventions in the light of a structural response framework. Overall, we find that: (1) market-based food interventions, including taxes on junk food, nutrition labelling, and marketing restrictions, decrease the consumption of targeted foods, (2) programs directly providing healthy foods are effective in reducing obesity, and (3) the construction of public areas for recreation increases the average frequency of physical activity. Although obesity-related interventions in the region have somewhat improved health behaviours, obesity prevalence remains on an upward trend. We discuss some opportunities to continue tackling the obesity epidemic in LATAM under a structural framework.

Sugars, Salt, Saturated Fat and Fibre Purchased through Packaged Food and Soft Drinks in Europe 2015-2018: Are We Making Progress?

The availability, purchase and consumption of foods high in fat, sugars and salt and low in fibre are linked to the high health and economic burden of noncommunicable diseases, including cancer, in Europe. Therefore, assessing the quality of the food offer is key as feedback to decision makers, as well as to identify good practices and areas of the food supply still requiring urgent action. We combined detailed market share and sales data with nutrition composition data to evaluate the nutritional quality of 14 packaged food and soft drinks categories sold across 22 European countries over the 2015-2018 period. Our analysis shows great variability of the nutritional composition within and among packaged food and soft drinks categories across European countries. Our estimates of the market-share weighted mean, a measure that integrates possible changes in nutrient content with the amount of a product sold to consumers, as well as daily per capita nutrient sale estimates, suggest a small but statistically significant progress in certain food categories only. Overall, the amounts of sugars, saturated fat, salt and fibre being sold to European citizens through these products is not improving to an extent to meet public health objectives.
