ALA from perilla is already available in some countries and krill, shrimp-like creatures abundant in the Antarctic Ocean, are being targeted by a Canadian company as a future Omega-3 source. Krill oil contains 25% Omega-3 EPA and DHA.
Genetic modification is also being explored, with one experiment inserting genes which will produce long-chain Omega-3 polyunsaturates into existing oilseed varieties. Another uses gene transfer technology to directly convert Omega-6 polyunsaturates to their Omega-3 counterparts.
Experts believe that four times or lower would be excellent and that consuming too many omega 6 foods relative to omega 3 foods increases the probability of a number of diseases, heart disease in particular.
Omega 3 is most commonly associated with the oils found in fish. Best known sources are mackerel, trout and salmon although the oils can be extracted from white fish; and the liver of the Cod is particularly rich as well. The American Heart Association recommends a daily intake of 1000 mg. of Omega-3 for measurable health benefits in cardiovascular care. There are various ways of including Omega 3's in your diet so you need not worry if you are not a big fan of fish.

The benefits of Omega 3 will continue to grow in importance as the population ages and looks for ways to maintain healthy and active lifestyles. Currently, Omega 3's are easy enough to buy from online companies and specialized pharmacies but it surely won't be long before Americans will be able to choose the supplement that suits them best from the shelves of local supermarkets and convenience stores.
The most common form of supplement is the capsule formulated from concentrated oils derived from those fish that have the high Omega 3 levels. Generally, the tablet will contain something around fifty percent from that source (fish) with the balance made up of other sources of fatty acids.
Omega 3 fatty acids are not restricted to fish oils - they can also be found in a number of plant extracts as well. The best source of Omega-3 is alpha-linolenic acid (ALA) which includes flaxseed (linseed) oil, rapeseed (canola) oil, chia seeds, walnuts and walnut oil, the Mediterranean plant, purslane, grass-reared meat, and dark green leafy vegetables. These items are widely found in health food stores and in natural health markets.
A relatively new addition to the omega 3 foods list is a fish called the Hoki, which contains naturally high levels of DHA and EPA fatty acids and comes from New Zealand where the waters are pristine.
Omega 3's can also be found in a wide range of other foods including vegetables and processed foods; however, the levels are negligible and provide no significant health benefits. Vegetarian Omega-3 supplements are available, usually as flaxseed (linseed) oil.
Before this happened, animals were free range and grazed on their natural diets, which, in the case of cows as one example, was grass. Their natural grass diet created naturally lean beef that was high in omega-3 fatty acids.
