Choosing a diet rich in various healthy fats is key to controlling inflammation and improving heart health for cancer patients.
The Role of Omega-3 Fatty Acids
Omega-3 fatty acids are key in fighting inflammation and preventing cancer. Our bodies can’t make them, so we must get them from foods like fish or supplements. People who eat a lot of omega-3s, found in salmon and other fish, face lower risks of colorectal, mammary, and prostatic cancers1011.
These fats play a major role in reducing inflammation, essential in stopping cancer from progressing. Western diets often have too much omega-6 and not enough omega-3, having a balance of 20:110. Omega-3s are important for building cell walls and helping cells work right, which helps prevent cancer12.
Eating plenty of omega-3 fats helps the body in many ways and makes cancer treatments work better. They can stop tumors from growing and help kill cancer cells without hurting normal cells. The EPA and DHA types of omega-3s are especially good at this11.
Studies show that eating fish rich in omega-3s lowers the risk of cancer and heart disease11. Cancer is the second leading cause of death after heart disease, so eating foods high in omega-3s is very important11. Plus, more omega-3s can make you healthier overall, reducing the risk of heart problems and stroke12.
In 2020, 17 million new cancer cases were expected10. Better diets could help improve survival rates and life quality for these patients. Omega-3s in an anti-inflammatory diet play a big part in fighting cancer and keeping you healthy. So, it’s a good idea to eat more foods high in omega-3s or think about taking supplements.
