The ratio present in linseed oil is about 4:1. So linseed oil is a good source of Omega 3. You should consume every day small portions of linseed or linseed oil. However, if linseed oil is used in the diet for a long time, without other oils, it may cause Omega 6 LA deficiency symptoms. So the best bet is to blend linseed oil with other oils that contain more Omega 6, in order to get the right balance, such as sesame oil, sunflower oil, evening primrose oil. Linseed oil is good for the heart because it is the richest source of alpha-linolenic acid. Linseed itself (ground or whole) also contains lignans, which may have antioxidant actions and may help protect against certain cancers, though not everyone agrees on this issue.
