This trend could cause an increase in premature deaths due to chronic illnesses, including cancer and cardiovascular disease.
To understand the relationship between ultraprocessed foods and the risk of anticipated early death, the researchers enlisted the help of 44,551
Researchers have calculated the intake and food consumption of each participant of ultra-high-level foods.
Ultraprocessed foods accounted for more than 14% of the total weight of food consumed and about 29% of total calories, they found. Ultraprocessed food consumption was associated with the younger age, lower income, lower education, life only, higher BMI and lower physical activity level.
During the study period, 602 participants died. After adjusting to factors such as smoking, researchers calculated a 14% higher risk of early death for each 10% increase in the proportion of consumed ultraprocessed foods.
Further studies are needed to confirm these results, the authors say. However, they hypothesize that additives, packaging (chemicals contained in food during storage) and processing itself, including high-temperature processing, may be factors that negatively impact health.
Read the package from front to back
The "conclusions make sense, given what we know to date on the deleterious effects of food additives on the function and on brain health, but the effects observed are very small, "wrote Molly Bray, president of the Department of Nutritional Sciences at the University of Texas at Austin, in an email. It was not involved in the research.
Nurgul Fitzgerald, an associate professor at the Rutgers Department of Nutritional Sciences, the State University of New Jersey, offered "congratulations to the authors" for a "strong" design study.
However, "ultraprocessed" is a huge category of foods, and by gathering so many things together, the researchers have lost sensitivity in their results and can not pinpoint what exactly is causing the effect seen in the study, said Fitzgerald, who was not involved in the research.
" Some factors may be more harmful or less harmful than others: it's really too complex, "he said, adding that we can not" run "with these results
because people eat more of these processed foods?
"We live in a fast world, and people are looking for cost-effective solutions, we are always tense for the time," Fitzgerald said. "People are looking for quick solutions, a quick meal".
When selecting food, taste is the number one factor for most consumers, he said, but price and convenience are also important, and with ultraprocessed foods that convenience factor is "probably on top of the list: get and go, ready to eat. "
Fitzgerald advises people to look not only at a parcel when they buy ready meals, but also at the back.
"Look at the list of ingredients, do you understand all those ingredients that come into your food?" she asked. Buy only those products "with the fewest ingredients and the ingredients you understand."
