In a recent study conducted by researchers from the University of Sao Paulo, a potential connection between ultra-processed foods and an increased risk of cancer was found. Although the findings imply a probable link, further investigation is required to fully comprehend and establish the relationship.
The study involved 107,038 participants, drawn from 21 cohorts across 10 European countries and Brazil. Information on participants’ dietary habits and cancer diagnoses were collected over a duration of 5.4 years, on average. Several factors were controlled for, including body mass index, smoking habits, and levels of physical activity.
The researchers categorized foods into three groups: ultra-processed (such as ready meals, puddings and processed meats), processed (including whole grains, yogurt, processed meats) and unprocessed or minimally processed (your fruits, vegetables, fish, eggs).
There was a significant increase in the risk of overall cancer in participants who consumed the highest proportions of ultra-processed foods, compared to those who consumed the least. Additionally, the risk seemed to rise with the increase in ultra-processed food consumption. Although this association was notably consistent across genders, ages, BMI categories, and education levels, these findings are still inconclusive.
Some researchers suggest that ultra-processed foods could contain compounds that may potentially promote tumor development, such as advanced glycation end products (AGEs), which are commonly found in high amounts within ultra-processed foods. However, these results are only indicative and require further analysis for confirmation.
This study contributes to a growing body of research on the correlation between ultra-processed foods and detrimental health outcomes. Previous studies have resulted in similar findings in relation to the impact of ultra-processed foods on weight gain, the risk of obesity, cardiovascular diseases, and even all-cause mortality.
Further research, including randomized controlled trials, is required to investigate the plausible relationship between ultra-processed foods and cancer risk. Meanwhile, researchers recommend limiting intake of ultra-processed foods and promoting the consumption of whole, unprocessed foods to give consumers the best possible chance of maintaining good health and preventing disease.
