Even small amounts of processed meat can greatly raise your cancer risk, the World Cancer Research Fund (WCRF) writes. The WCRF update their guidelines every decade, and in this one, they outline three main problems: tobacco, red processed meat, and alcohol (酒精). 1．Almost half of all cancer cases are preventable, they write, and the most straightforward way is through a healthy diet. But what does that mean?                           

No smoking

2．While this is not strictly a part of a healthy diet, smoking has long been proven to cause a wide variety of cancers, as well as increase the risk for cardiovascular diseases and other serious health issues

Avoid alcohol

Decades ago, people thought that you could enjoy alcohol in low to moderate quantities without causing a health risk. Recent research seems to suggest that even in low quantities, drinking alcohol can greatly increase, your risk of cancer.3． So, better avoid it.

Red meat

The list wouldn’t be complete without red meat. As other studies before it, the WCRF report further emphasizes that red meat is also associated with an important rise in cancer risk, especially processed red meat. 39.4．No amount of processed red meat is safe if you want to minimize your risk of cancer.

The findings don’t necessarily offer something －they just repeat what mountains of research are already saying: if you want to avoid, cancer, you need to eat more things that are good for you, less of the things that are harmful to you, and be at least somewhat physically fit.5．
