A large study of nearly 30,000 women under 50 found that those eating the most ultraprocessed foods had a 45% higher risk of developing adenomas (growths that can lead to early-onset colorectal cancer)than those eating the least.
The link remained even after accounting for other risk factors like BMI, diabetes and fibre intake.
Ultraprocessed foods are often high in sugar, salt, unhealthy fats and additives, and their rising consumption parallels increases in early-onset colorectal cancer.
While diet doesnβt explain all cases, researchers say cutting back on these foods could help lower risk.
