Omega 3 Fatty Acids

Many times, new research studies that have been published contradict findings from previous studies. And now omega 3 fatty acids have entered the list of nutrients that may not be as helpful as previously thought. Recently, The British Medical Journal has published a report by researchers that omega 3 fatty acids do not help everyone's health. However, there has been no evidence to show that they are harmful either.

Not all reports have reached the same conclusions. A similar study conducted has found that people who consume large amounts of omega 3 fatty acids have a lower mortality rate due to a decreased risk of heart attacks and strokes.

Foods that contain omega 3 are generally healthy foods: fish (salmon, mackarel, sardines), flax seeds, nuts and canola oil. These are foods which are an important part of one's diet. Omega 3 fatty acids play an important role in the proper function of the body. During pregnancy, it plays a vital role in the healthy development of the fetal nervous system. Omega 3 is also vital in the development of the nervous system of young children. This makes fish problematic - they are an excellent source of omega 3 but fish can also contain mercury and dioxins.

Pregnant women, nursing mothers and young children should only eat up to 350 grams of low-mercury fish a week (salmon, light tuna). Everyone else is recommended to have fish a few times a week, as a source of protein.
