Breast cancer is still a scourge for women. However, this disease can be prevented by making healthy lifestyle, among others, often eat fish rich in omega – 3 fatty acids.
The researchers analyzed 26 studies of China’s international involving 900,000 women, including 20,000 of whom had breast cancer. They found that women who consumed omega – 3 fatty acids from fish most often have a reduced risk of breast cancer 14 percent less.
The study results also showed a decrease in risk with dose relationship. Mentioned, each 0.1 gram increase in consumption levels of omega – 3 per day was associated with a 5 percent reduction in the risk of breast cancer. As a comparison, one serving of salmon contains 4 grams of omega – 3 fatty acids.
Omega- 3 fatty acids are a type of unsaturated fat that has been known to prevent heart disease and cancer.
However, the researchers say the consumption of omega – 3 fatty acids from plants did not show the same effect in reducing breast cancer risk.
In addition, they also discovered the benefits of omega – 3 to reduce the risk of breast cancer is different in each population. In Asians, the benefits may not be as big as the West. According to the researchers, this may occur due to differences in sources of omega – 3 are eaten.
The benefits of omega – 3 in fish is considered the most well to reduce the risk of breast cancer. While not yet clear whether the consumption of omega – 3 supplements also provide the same effect.
A review of 48 studies concluded that it is still unclear consumption of omega – 3, either from food or supplements, may alter the risk of heart disease or cancer. But that does not mean people should stop a diet rich in omega – 3.
