Where do we can find Omega 3?

Where do we can find Omega 3? About 30 grams of walnuts provide our body with almost 2 grams of alpha-linolenic acid (one of the fatty acids of the Omega 3 group). Linseed oil is by far the richest plant source in Omega 3 and the most useful for maintaining a balanced diet even excluding foods of animal origin.

Omega 3 is mainly contained in some types of fish, but we can find them also in some vegetables and legumes. Spinach, broccoli, lettuce and green cabbage, in addition to being very important sources of vitamins and minerals, also contain a small percentage of Omega 3.

Algae, very popular in Japan and other eastern countries, seaweed has now entered the market also in the West as an alternative food and with numerous nutritional virtues. Among these, there is also the richness of Omega 3.

Omega 3 needs for the protection of the circulatory system and for the prevention of cardiovascular diseases. The daily requirement of Omega 3 is, on average, about 3 grams. Omega-3 fatty acids are part of the polyunsaturated and their chain includes various double bonds interrupted by methylene bridges (-CH2-) so that there are two single bonds between each pair of adjacent double bonds.

EPA and DHA acids can be synthesized by the human body from ALA acid, but only in small quantities. In practice, the DHA rate does not vary despite the increased intake of ALA. On the market you can find numerous compounds based on Omega-3, many of these contain Omega-3, Omega-6, precursors of Omega-3 variously mixed together or with vitamin associations, all these compounds belong to the category of food supplements.

The European Medicines Agency (EMA) has concluded that omega-3 fatty acid medicines are not effective in preventing the recurrence of heart and circulatory problems in patients who have had a heart attack. The conclusion, based on a reassessment of the data collected over the years, is that these medicines will no longer be authorized for such use.
