Colorectal cancer is increasingly affecting younger adults, especially those under 50, particularly in wealthier countries like the U.S. Researchers from Harvard and Mass General Brigham have discovered a potential link to ultraprocessed foods.
A recent study involving nearly 30,000 women found that those eating high amounts of ultraprocessed foods—like ready-to-eat meals packed with sugar and unhealthy fats—had a 45% higher risk of developing adenomas, which can lead to early-onset colorectal cancer, compared to those who ate fewer of these foods. This groundbreaking research was published in JAMA Oncology.
Senior author Andrew Chan, a gastroenterologist at Mass General Brigham Cancer Institute and a Harvard professor, emphasizes the need to reduce ultraprocessed food intake to combat the rise of early-onset colorectal cancer. He highlights that the risk increases linearly—the more ultraprocessed food consumed, the greater the risk of developing polyps.
The study analyzed data from the Nurses’ Health Study II, which tracked female nurses born between 1947 and 1964. These women completed dietary surveys every four years and underwent at least two endoscopies before age 50. On average, participants consumed 5.7 servings of ultraprocessed foods daily, accounting for 35% of their total calories.
Among the participants, 2,787 developed polyps associated with colorectal cancer. Those consuming about ten servings a day faced significantly higher risks compared to those with lower consumption.
Interestingly, while the study is a major step, Chan notes that ultraprocessed foods alone do not explain the entire rise in early-onset colorectal cancer. Many patients report healthy diets yet still develop the disease. This highlights the need for further research into additional risk factors, such as genetics and lifestyle choices.
As people become more conscious of their diets, social media trends reflect a growing awareness of the dangers of ultraprocessed foods. In 2023, a survey by the American Cancer Society indicated that many adults are trying to cut down on processed foods, yet many still struggle to make healthier choices.
In summary, while ultraprocessed foods might be a key player in the rise of early-onset colorectal cancer, ongoing research aims to uncover other contributing factors. Recognizing that diet is just one piece of the puzzle could lead to a more comprehensive understanding of this troubling trend.
