Ultra-Processed Foods Linked to Increased Risk of Precancerous Colorectal Growths in Women Under 50
A new study published in JAMA Oncology has found that consuming ultra-processed foods may increase the risk of developing precancerous colorectal growths, known as adenomas, in women under 50. The research, which followed 29,105 nurses under 50 who underwent at least one colonoscopy, revealed that women who consumed an average of 10 or more ultra-processed food servings per day had a 5% risk of developing adenomas, compared to a 3% risk for those who consumed an average of three servings per day.
According to Dr. Céline Gounder, a medical contributor to CBS News and editor-at-large for public health at KFF Health News, “You do see an increase in risk with more servings of ultra-processed food products.” The study’s findings are concerning, given that ultra-processed foods account for more than half of the average American’s diet, despite most dietary guidelines recommending restricting them. Ultra-processed foods have also been linked to dozens of other health issues, including diabetes, sleep issues, heart trouble, and early death.
What are Ultra-Processed Foods?
Ultra-processed foods do not have a set definition, but they often include packaged foods and beverages, items made without many whole ingredients, and less obvious products like condiments and sauces. Examples of ultra-processed foods include packaged snacks, sugary drinks, and frozen meals. Study participants who had diets higher in sugars and artificial sweeteners, as well as packaged savory snacks, had higher rates of adenoma development.
Dr. Gounder notes that “I don’t know if there are any good ultra-processed foods. Clearly, the more you’re eating, the worse for your health, the higher the risk for various complications.” The federal government has announced plans to define ultra-processed foods, but in the meantime, a good rule of thumb is to avoid foods with ingredients that are difficult to pronounce.
How Do Ultra-Processed Foods Affect the Body?
Researchers are still working to determine exactly how ultra-processed foods affect the body. However, it is believed that ultra-processed foods can alter the gut microbiome, leading to increased inflammation and permeability of the gut wall. Additionally, ultra-processed foods are associated with an increased risk of obesity and diabetes, which are also risk factors for various cancers, including colon cancer.
The study’s findings highlight the importance of a balanced diet and a healthy lifestyle in reducing the risk of precancerous colorectal growths. As Dr. Gounder emphasizes, “We think that the ultra-processed foods are changing your microbiome, so those are the bacteria in your gut. So that causes increased inflammation, it can cause increased permeability of the gut wall.” For more information, visit Here
