They are the best defense for a certain type of cancer.
Colon cancer rates are rising significantly among younger adults, but recent research suggests that improving dietary habits could help reverse this trend. The American Cancer Society reports that about 20% of colon cancer diagnoses occur in individuals aged 54 and younger, nearly double the rate seen 30 years ago. However, studies from Flinders University in the U.K. indicate that increasing fiber intake and adopting healthier eating patterns could reduce the risk.
Yohannes Melaku, a senior researcher and nutritional epidemiologist at Flinders Health and Medical Research Institute, explained that their research identified direct links between poor diet and digestive cancers. The studies highlighted the benefits of consuming a diet rich in healthy fats and vegetables while limiting sugar and alcohol intake. Such dietary changes could potentially lower the risk of colon and other cancers.
The research, published in the European Journal of Nutrition, found that individuals who consumed the most fiber and unsaturated fats had a 15% lower risk of developing colon cancer. Melaku noted that high-fiber foods, such as fruits and vegetables, help promote healthy gut bacteria that can reduce inflammation. He emphasized that fiber and healthy fats should be a key part of everyone’s diet.
An earlier review of evidence indicated that a diet high in red and processed meats, alcohol, refined carbohydrates, and sugary drinks was associated with a 14% increased risk of colon cancer. Conversely, a diet rich in fruits, whole grains, legumes, vegetables, milk, and dairy products was linked to a 17% reduced risk.
The researchers stress the need for more clinical trials to further explore the impact of diet on colon cancer. Amy Reynolds, a clinical epidemiologist at Flinders University, emphasized the importance of incorporating nutrition-focused research in clinical settings to better understand the connection between diet and gastrointestinal cancers. GI cancers, which include colon, rectal, and other digestive cancers, account for a significant portion of cancer cases and deaths worldwide. The researchers hope that their findings will serve as a reminder of the importance of nutrition in preventing disease and promoting long-term health.
