How diet affects cancer risk
So-called highly processed foods such as frozen pizza, chips and deli meats, are associated with a variety of adverse health effects. In particular, their consumption seems to pose a different risk cancers and an associated one premature death to increase significantly.
In a new study involving experts from Imperial College London The relationship between the consumption of highly processed foods, the risk of 34 site-specific types of cancer and the associated mortality was examined. The results can be found in the journal “eClinicalMedicine“ to be read.
Data from the UK Biobank study analysed
For the research, the team analyzed data from a prospective cohort of people who were part of the UK Biobank Study were. The participants were aged 40 to 69 years and provided information on their food consumption between 2009 and 2012.
All participants underwent medical follow-up until January 31, 2021. In addition, the food consumed was with the help of a special food classification system (NOVA) assigned to different categories. The experts focused on level of food processing.
How many highly processed foods the participants consumed was calculated by the researchers as a percentage of total food intake (g/day) expressed. Then, with the help of models, the expected connections between the consumption of highly processed foods, the risk of cancer and death from cancer were determined.
The average consumption of highly processed foods within the total nutrition was attached to the participants 22.9 percentwhich indicates how frequently these foods are consumed in normal everyday life.
About 4,000 participants died of cancer
In the mean follow-up period of 9.8 years, all fell ill 15,921 participants of cancer and 4,009 people did not survive their cancer, reports the team.
Analysis of the data showed that an increase in the consumption of highly processed foods by only ten percent, was associated with an overall increased incidence of cancer. The risk for ovarian cancer.
In addition, the risk of dying from cancer also increased when the consumption of highly processed foods was increased by 10 percent. at ovarian cancer and breast cancer this increase was particularly noticeable.
In summary, the results of the study suggest that a higher consumption of highly processed foods is associated with an increased burden and mortality for general and certain types of cancer, the researchers conclude.
Especially the risk for ovarian cancer is apparently significantly increased by highly processed foods.
Diet-related colorectal cancer
In another research paper, which was recently published in the English-language journal “BMJ“ was published was a high consumption of highly processed foods however, especially in men with an increased risk of colorectal cancer tied together.
There were also certain Subgroups of highly processed foodswhich were associated with an increased risk of colorectal cancer in both men and women.
Eating healthier to protect once morest cancer
Consumption of relatively cheap, tasty, and ready-to-eat processed foods is increasing around the world. And a growing body of research indicates that these foods can contribute to an increase in cancers and related deaths to lead.
Therefore, urgent efforts should be made to help people worldwide become healthier nutrition to motivate. This might not only prevent cancer, but also bring a variety of other benefits, such as fewer cases of obesity and obesity and fewer cardiovascular and metabolic diseases. (as)
