Dietary Habits and Cancer Risk
Eating habits can affect how likely someone is to get cancer.
Eating lots of fruits, vegetables, and whole grains can lower the risk.
These foods help keep insulin and inflammation levels low, which are linked to cancer.
On the other hand, eating too much processed meat, red meat, and ultraprocessed foods can increase the risk.
Alcohol is also bad for cancer risk, even in small amounts.
Drinking coffee or tea and eating dairy can be good, but it's important to keep a healthy weight and exercise.
Being overweight is a big risk factor for many types of cancer.
So, eating healthy and staying active can help lower the chance of getting cancer.
Eating patterns rich in whole grains, fruits, vegetables, and lean/plant-based proteins are linked to lower cancer risk due to reduced insulin and inflammation.
Processed meats are carcinogenic, and red meat is 'probably carcinogenic'; limiting intake is recommended.
Ultraprocessed foods, high in sugar and preservatives, are linked to increased cancer risk, particularly breast and prostate cancer.
Alcohol increases cancer risk, with no safe level; quitting or reducing intake is advised.
Obesity is strongly linked to multiple cancers, and maintaining a healthy weight through diet and exercise is crucial.
