Routinely eating fatty fish have a positive benefit in preventing breast cancer risk. According to a recent study from Zhejiang University in Hangzhou, China, the species of fish that have n-3 polyunsaturated fatty acids (PUFA) are able to provide a protective effect for the breast. Thus quoted from the Health.
Fatty fish can be found in many types of fish. Examples are salmon, tuna, and sardines. Polyunsaturated fatty acids contained in the fish involved in sending chemical messages to the brain. Then, the effect is to regulate the activity of blood vessels and boost the immune system. In addition, these fatty acids are very good for lowering the risk of heart problems.
This study is actually contrary to previous studies that found no link between the protection of polyunsaturated fatty acids on the risk of breast cancer. However, researcher Duo Li who is also a professor of nutrition, trying to dig back and analyze the results of the 21 studies. Duo Li and his team analyzed a variety of related studies involving 800 thousand women in the United States, Europe, Asia, along with 20 thousand cases of breast cancer.
The result was different. The research team saw between polyunsaturated fatty acids, and breast cancer risk is related. Eat most types of polyunsaturated fatty acids can reduce the risk of breast cancer by up to 14 percent. Any increase in the consumption of these fatty acids by 0.1 grams per day, will reduce the risk of up to 5 percent.
“Increased intake of n-3 PUFAs have a protective effect for breast cancer,” said Duo Li.
“One to two servings of oily fish per person per week is recommended,” he added.
But need to be careful. Too much eating some fish may also be unhealthy. Some fish contain mercury. The study was published online June 27 in the journal BMJ.
