A two-week dietary intervention increased fiber intake, altering gut microbial composition and short-chain fatty acids production. Researchers found a significant increase in Bifidobacterium abundance despite no detectable shift in fatty acid levels.
Researchers found that most classification systems' criteria diverge from scientific evidence on nutrition and food processing. A lack of consistency in categorizing foods deemed 'ultra-processed' and home-cooked foods hinders informed decision-making, according to the study.
A large study found a strong association between ultra-processed food consumption and an increased risk of colorectal cancer, with a 10% increment in consumption leading to an 11% increase in risk. Ultra-processed foods were also linked to less healthy diets among breast cancer cases, while no association was found with prostate cancer.
