Research has shown that children who regularly consumed fish had a four times lower risk of developing asthma than children who don`t.
Eating fish benefits those who are at high risk of ischemic heart disease. Recent research has shown that two forms of omega-3 fatty acid EPA and DHA have a significant impact on the stiffness in the large arteries which can lead to systolic hypertension and increased pulse pressure. This study adds to previous research on the benefits of omega-3 fatty acids such as the lowering of triaglycerols which reduce the risk of heart disease.
There is good evidence to show that a high omega-3 diet can protect against prostate and breast cancer. Studies have also shown that there is a possibility that omega-3 fatty acids stimulate the death of tumour cells. Omega-3s also play an anti inflammatory in the body and can help to alleviate symptoms of conditions ranging from psoriasis to rheumatoid arthritis.
