Can food choices influence cancer risk?

A 2018 study that included data on almost 105,000 people found that increasing the dietary proportion of ultra-processed foods by 10% had associations with a significant 12% increased risk of overall cancer and an 11% increased chance of developing breast cancer.Ultra-processed foods are rich in saturated fat, added sugar, and salt but low in protective nutrients, such as fiber, vitamins, and minerals. It is important to try to limit consumption of ultra-processed products as much as possible to reduce the risk of developing these conditions.A diet high in added salt may increase the risk of certain cancers, particularly stomach cancer.Scientists have suggested that high salt intake may increase the risk of infection caused by Helicobacter pylori bacteria. Consuming a varied diet that provides optimal amounts of fiber, vitamins, minerals, and beneficial plant compounds is essential for overall health and cancer risk reduction.In addition to consuming a diet rich in plant-based foods, reducing intake of processed and red meats, ultra-processed foods, and added sugars and salt may help reduce the risk of certain cancers and many other chronic conditions. Though many factors can influence a person’s risk of developing cancer, including factors that a person cannot control, research shows that some dietary patterns and specific foods may increase the chance of developing certain cancers.Evidence suggests that ultra-processed foods, processed meat products, diets high in added salt, and drinking scalding beverages may increase the risk of cancer development.
