Mothers who had omega-3 fatty acids in their diet during pregnancy and lactation may be creating a protective shield against their daughter's risk of breast cancer.
Scientists from Louisiana State University who presented the research findings at the 96th Annual Meeting of the American Association for Cancer Research said that babies who also had continued to have diet rich in omega 3 fatty acids will be benefited the most from their mother's diet.
Researchers have also pointed out that conversely, mother's diet consisting of omega 6 fatty acids will increase the risk of daughter's breast cancer.
Omega 3 and omega 6 fatty acids are polyunsaturated fats that form the basic of one of the four types of fatty acids essential to the body. Body cannot synthesize these essential fatty acids and so they have to be eaten for the body to accept them. These are found in grains, most plant-based oils, poultry, and eggs as well as in fishes, canola and flaxseed oils, soybeans and nuts.
The research report, which is based on study of mice, says that maternal diets that are high in omega-3 fatty acids decrease the maternal estrogen levels. This in turn affects the increase in immunity that leads to less risk of breast cancer in daughters'.
