What is Omega 3?

Omega-3 fatty acids are considered essential for human health as they are a type of polyunsaturated fatty acid that cannot be endogenously synthesized by the body and must be obtained through dietary sources. Omega-3 fatty acids are widely recognised for their numerous health benefits and play a crucial role in various physiological processes within the human body. 

There are three primary classifications of omega-3 fatty acids

1. Alpha-Linolenic Acid (ALA) can be obtained from many plant-based sources such as hemp seeds, walnuts, chia seeds, flaxseeds, and other similar foods. While ALA is recognised as a significant omega-3 fatty acid, its health benefits are comparatively less pronounced when compared to EPA and DHA. Despite the limited conversion rate, the human body is nevertheless capable of converting a little quantity of alpha-linolenic acid (ALA) into eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

2. Eicosapentaenoic Acid (EPA) can be obtained from fatty fish species such as salmon, mackerel, sardines, and herring. These fish are considered to be valuable sources of EPA. It is associated with cardiovascular well-being, mitigates inflammation, and is widely recognised for its anti-inflammatory properties.

3. Docosahexaenoic Acid (DHA): Like the Environmental Protection Agency (EPA), docosahexaenoic acid (DHA) is predominantly present in marine origins, with a special emphasis on fatty fish. Docosahexaenoic acid (DHA) plays a vital role as a fundamental component of the brain and retina, and its presence is essential for the preservation of optimal brain function and health. Early childhood and foetal development are of particular importance.

Omega-3 Supplements

Omega-3 supplements are classified as dietary supplements that offer a concentrated form of omega-3 fatty acids, which are considered indispensable lipids recognised for their diverse physiological advantages. Various varieties of supplements are accessible, including fish oil, krill oil, and algal oil, which specifically caters to the dietary preferences of vegetarians and vegans. When incorporating omega-3 supplements into one’s regimen, it is crucial to take into account the following essential factors:

Types of Omega-3 Fatty Acids

Omega-3 supplements commonly comprise many forms of omega-3 fatty acids, including but not limited to the following:

Eicosapentaenoic Acid

(EPA) is recognised for its anti-inflammatory effects and its potential to promote cardiovascular health.

Docosahexaenoic Acid

(DHA) is a crucial nutrient that plays a vital role in promoting optimal brain and ocular health, with a special emphasis on the developmental stages of children and expectant mothers.

Alpha-Linolenic Acid

(ALA) is a fatty acid that is predominantly derived from plant-based sources. It possesses the ability to undergo conversion within the human body into eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). However, it is important to note that the conversion rate of ALA into EPA and DHA is restricted.

Fish Oil vs. Algae Oil

The utilisation of fish oil supplements as a prevalent means of obtaining eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) is well-established. These supplements are mainly produced from fatty fish species such as salmon, mackerel, and sardines. Krill oil represents an additional marine-derived reservoir of omega-3 fatty acids. Algae oil supplements offer a viable option for individuals adhering to vegetarian and vegan diets, as they serve as a supply of EPA and DHA derived from algae. These essential omega-3 fatty acids are commonly obtained by fish from algae.

Quality and Purity: When making a choice about omega-3 supplements, it is imperative to opt for items of superior quality that are manufactured by trustworthy companies. It is advisable to seek out dietary supplements that have undergone rigorous testing to ensure their purity and have been subjected to screening processes to detect the presence of pollutants such as heavy metals, polychlorinated biphenyls (PCBs), and dioxins.

Potential Adverse Effects: Omega-3 supplements are often considered to be safe when used in accordance with suggested guidelines. Nevertheless, the administration of elevated amounts may result in adverse effects such as gastrointestinal disturbances, the presence of a fish-like taste in the mouth, and an augmented susceptibility to bleeding. It is advisable to seek guidance from a healthcare practitioner prior to initiating the use of omega-3 supplements, particularly in cases where individuals have a bleeding disease or are concurrently using blood-thinning drugs.

Interactions: Omega-3 supplements have the potential to interact with specific pharmaceuticals, such as anticoagulants and antiplatelet agents. It is advisable to communicate with your healthcare practitioner regarding any dietary supplements you may be consuming, in order to ascertain the absence of any interactions with your prescribed drugs.

Consideration of Individual Needs: The determination to incorporate omega-3 supplements into one’s dietary regimen should be predicated upon an assessment of their distinct food consumption, health objectives, and any preexisting health ailments. Certain individuals may experience advantages from the utilisation of omega-3 supplementation, whereas others may acquire an adequate amount of omega-3 fatty acids by their dietary intake.

Omega 3 Fatty Acids Foods

Omega-3 fatty acids are classified as indispensable lipids that confer many physiological advantages, particularly in relation to cardiovascular and neurological well-being. Omega-3 fatty acids can be found in fatty fish as well as in plant-based sources. Below is a compilation of food items that are abundant in omega-3 fatty acids:

Fatty Fish

  • Salmon
  • Mackerel
  • Sardines
  • Trout
  • Herring
  • Albacore tuna (particularly in canned form)
  • Anchovies
  • Flaxseeds (ground or flaxseed oil)
  • Chia seeds
  • Walnuts
  • Hemp seeds (hemp hearts)
  • Algal oil (derived from algae and available as a supplement)
  • Brussels sprouts (contain a small amount of ALA, a type of omega-3)
  • Shrimp (contains lower amounts compared to fatty fish)
  • Cod liver oil (available as a supplement)

It is noteworthy to acknowledge the existence of distinct categories of omega-3 fatty acids, namely EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), predominantly sourced from fatty fish and seafood. Alpha-linolenic acid (ALA) is an additional variant of omega-3 fatty acids, predominantly present in plant-derived sources such as flaxseeds, chia seeds, and walnuts.

Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are well recognised as having higher potency and a more immediate positive impact on human health. Although alpha-linolenic acid (ALA) retains some value, it is comparatively less efficacious than eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in conferring similar health advantages. Nevertheless, the human body has the capacity to metabolise a limited amount of alpha-linolenic acid (ALA) into eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). However, it is important to note that the rate of conversion is comparatively modest.

To ensure you’re getting a sufficient intake of omega-3 fatty acids, consider incorporating a variety of these foods into your diet. Fatty fish are considered to be highly advantageous in terms of omega-3 content, making them a prime option for meeting dietary requirements. It is advisable to incorporate fatty fish into one’s diet on a regular basis, ideally consuming them multiple times each week. For individuals with dietary limitations, plant-based sources and omega-3 supplements, such as those derived from algae, can serve as beneficial alternatives. It is advisable to get guidance from a healthcare professional or nutritionist in order to obtain personalised dietary advice.
