LIST OF FOODS RICH IN OMEGA 3
What foods are rich in omega-3?
Omega 3 is a family of fatty acids that mainly consists of 3 components: linolenic acid, eicosahexaenoic acid (EPA) and docosahexaenoic acid (DHA).
In general, the main sources of omega 3 are found in plants (fruits, nuts and seeds) in the form of linolenic acid, which is an essential fatty acid (the body can not produce it). Oils obtained from nuts and seeds concentrate these fats and are rich in omega-3.
In our body, the liver can convert omega 3 from vegetables and oils into EPA and DHA, which are not considered essential (the body can manufacture them).
Omega 3 is a type of polyunsaturated fat, this means that it is unstable to heat. Therefore, vegetable oils containing omega 3 are very sensitive and should not be used for cooking or frying. They should be used raw in salads or dressings.
Vegetable oils rich in omega 3
Vegetable oils are those with the greatest amount of omega 3. Containing the highest proportion, we have cold-pressed flaxseed oil, followed by walnut oil.
It should be specified that omega 3 is a type of fat very sensitive to heat and oxidation. Therefore these oils should never be used for cooking and it is recommended to consume rich-antioxidant fruits that help protect the omega 3 oxidation.
Other vegetable oils that contain omega 3 in large quantity are soybean oil, canola oil, wheat germ or corn oil.
Foods rich in omega 3
The main foods with much omega-3 from plant sources are, in order of importance:
- Ground flax seeds 1 tablespoon (10g) contains 2.3 g of omega-3
- Ground chia seeds 1 tablespoon (10g) contains 1.8 grams of omega-3
- Shelled hemp seeds1 tablespoon (10g) contains 1 g of omega-3
- Walnuts: 7 walnuts provide 2.5 g of omega-3
What is the best source of omega-3?
The best sources of omega 3 are the foods that contain it, rather than oils rich in omega-3.
When omega-3 is found in foods, for example in flax seeds, it is protected from oxygen and retains its structure and properties. It keeps well for months, so we should only grind the seeds before eating them, in order that these fats to be released.
Instead, linseed oil, after processing, is very susceptible to oxidation (by contact with oxygen, by light, etc.) And therefore its omega3 easily deteriorates. It should be kept in a refrigerator. It only lasts a few months before becoming rancid.
Therefore, if we want to eat much omega-3, we do from ingesting flax, chia or nuts daily. Other foods that also provide a certain amount of omega 3, although in much lower amounts than the above, are: almonds, soybeans, chickpeas, purslane, spinach, strawberries, cucumbers, Brussels sprouts, cabbage, etc.
Animal foods rich in omega 3
The richest omega-3 animal foods are semi-fat oily fish (bluefish)
- Blue Fish: Oily fish is the richest food in omega 3. Among this type of food, from most to least, we have: Capsules of concentrated fish oil, capsules of cod liver oil, sardines, anchovy, salmon, Cod (especially liver), Herring, Mackerel, Tuna. Small fish are recommended because the big fish contaminated by mercury.
In a fewer amount than fish.we point out:
- Seafood: Lobsters, crabs, shrimp, etc.
- It has been reported that the meat of grazing animals contains more omega-3 than meat from animals fed intensively.
