World Fight Against Obesity Day

On World Obesity Day, it is important to remember that obesity is one of the greatest threats to public health in the 21st century. Obesity has long since ceased to be an individual problem and has become a global challenge, with a direct impact on quality of life, healthcare systems and the economic sustainability of countries.

Data recently published in the journal Nature reveal a worrying global trend: the number of adults and children with obesity continues to rise in virtually every region of the world. This high prevalence of obesity reflects profound changes in dietary patterns and lifestyles. The growing consumption of ultra-processed foods, high in sugar, fat and salt, combined with a sedentary lifestyle, is contributing to an increase in diseases such as type 2 diabetes, high blood pressure, cardiovascular diseases and certain types of cancer.

The associated costs are enormous. In Portugal, according to recently released data, the Portuguese currently spend over 613,000 euros a day on weight-loss medication. This figure highlights not only the scale of the problem, but also the urgent need to invest more in prevention rather than merely in treatment, given the significant social and economic inequalities in access.

It is in this context that projects such as ReFOOD4North take on particular significance. This project aims to develop healthy and sustainable functional meals based on local produce from northern Portugal, whilst promoting public health, environmental sustainability and the enhancement of the region. Food should be seen as a tool for prevention and well-being, rather than merely as a belated response to illness.

Tackling obesity requires an integrated approach: nutrition education, environments that facilitate healthy choices, the promotion of physical activity, and public policies that bring science closer to communities. The future of health begins, quite literally, on the plate.
