We know omega-3 are healthy, but we do not act accordingly


Apparently, and according to a recent study performed in the United States and in Germany, in spite of we have an adequate knowledge of nutrients and their health effects, including those of omega-3 fatty acids, our Omega-3 Index (the percentage of EPA+DHA with respect to total fatty acids in red blood cell) is below the recommendations for cardiovascular protection ( ≥8%). All participants in this study believed that a balanced diet is important for health, and more than half believed specifically that omega-3 are beneficial for heart and brain health, and besides, they could correctly identify the food sources (mackerel, salmon, herring, sardines, anchovies, and tuna are among the best sources of EPA and DHA). About one-third of participants believed their diet was adequate in omega-3 fatty acids… But they were wrong: 99% of them did not have an adequate Omega-3 Index.

Oily fish and shellfish are the more important natural source of EPA and DHA, but without an adequate oily fish consumption (two fatty fish meals per week), it may be difficult to obtain the optimal level of omega-3 fatty acids from foods alone. In this case, dietary supplements or food fortified may be required to achieve recommended intake.

DHA increases the Omega-3 Index more than EPA

Omega-3 fatty acids are needed by our body not only for normal cellular functioning, but they also have beneficial effects on our health. These beneficial effects are particularly [...]
