Inflammatory diets, ultra-processed foods may increase Crohn's disease risk

Inflammatory bowel disease (IBD) is a group of chronic conditions that damage the intestines and can cause uncomfortable symptoms. Preventing IBD remains a challenge, and research is underway to minimize this risk. A recent systematic review and meta-analyses identified dietary choices that may affect risk for Crohn’s disease, a major type of IBD. The study saw benefits from a Mediterranean-style diet and increased risk from diets containing inflammatory and ultraprocessed foods.

High amounts of ultra-processed foods may increase lung cancer risk by 41%

As the proportion of ultra-processed foods (UPFs) in the Western diet increases, concerns are growing about their health effects. Studies have linked UPFs with many health conditions, including obesity, type 2 diabetes, cardiovascular disease, and several types of cancer. Now, a study suggests that high consumption of UPFs could increase a person’s chance of developing lung cancer. While observing a link, the study cannot prove that UPFs cause lung cancer, but highlights a need for further studies.

Why are colorectal, other GI cancers on the rise in younger people?

Increasing age is the greatest risk factor for all types of cancer, with most cases being diagnosed in people over the age of 60. However, in people under 50, there has been a rapid, worldwide increase in cancers of the digestive system, or gastrointestinal cancers. Although still far less common than in older people, early-onset colorectal cancer is now the leading cause of cancer-related deaths in men, and the second in women, in the United States. The exact cause is unknown, but the authors of a new review published in the British Journal of Surgery suggest that obesity, a Western-style diet, nonalcoholic fatty liver disease, smoking, excessive alcohol use, and even exposure to microplastics, may all be contributing to the rise. Another study, published in Nature Medicine, has further estimated that, without early intervention, as many as 15.6 million gastric cancer cases may occur in the next few decades, most of which, are attributable to infection with a common bacterium, Helicobacter pylori.
