Reacción a "Study shows correlations between consumption of different types of ultra-processed foods and mortality"

This US study examined the relationship between ultra-processed foods and risk of death over more than 30 years of follow-up. It was based on a large sample of nurses and health professionals, exceeding 150,000 participants with no history of cancer, cardiovascular disease or diabetes. 

This research contributes to the available body of evidence on the negative health effects of ultra-processed foods. It found that those who consumed a greater amount of these foods had a slightly higher risk of death compared to those who consumed less. This risk was especially notable in deaths from neurodegenerative diseases. 

The study provides novel results by examining the link of specific subgroups of ultra-processed foods to mortality. Ready-to-eat meat, poultry and seafood products were found to be associated with increased all-cause mortality, as were sugar-sweetened and artificially sweetened beverages, dairy desserts and ultra-processed breakfast products. 

It is important to note that the sample consisted mainly of health professionals, which limits the generalisability of the results to other populations. Furthermore, being an observational study, a causal relationship between the consumption of ultra-processed foods and mortality cannot be established. 

Despite these limitations, the study suggests that limiting certain ultra-processed foods may have long-term health benefits. This has important implications for clinical practice and public health policy, as it provides further evidence that should be taken into account in dietary recommendations and regulation of unhealthy foods.
