Highly processed foods, those that are heavily treated during processing, cooking and preparation in general, can contribute to the obesity study that appeared in the journal Cell Metabolism, a study that was later taken up by the Los Angeles Times.
The results were obtained through a four-week trial that saw 20 healthy volunteers eating different dishes, some simpler, others much more tempting and ultra elaborate, from toasted French bread with cinnamon to quesadillas of turkey and scampi.
Analyzing the volunteers’ caloric intake and several other factors, primarily weight gain, the researchers found that there were clear differences when patients consumed unprocessed ingredients or meals dominated by ultra-processed foods.
The “epidemic” of obesity that is spreading in the United States is increasingly worrying: almost 40% of U.S. adults are now obese, double the numbers of the early 80s according to data from the Centers for Disease Control and Prevention.
And this without mentioning the rate of obesity among children, which is even higher. It is clear that there is something wrong with the American way of eating and the doctors who carried out this research believe that processed foods can be considered among the main negative factors along with others such as sugars and fats.
On the other hand, the American diet itself has changed a great deal in recent decades: from more “natural” foods with little chemical or industrial processing, in the space of a few years we have moved on to meals made only from increasingly processed foods, such as canned foods, not only meat but also vegetables, which see an industrial preparation process that obviously has a heavy impact.
