What Are the Potential Benefits of Omega-3?

Hands up if you remember those days in the '90s when your parents would coax you into swallowing spoonfuls of thick, fishy-tasting liquid, claiming it was for your health. Well, that fishy concoction contained Omega-3 fatty acids (DHA and EPA), but what exactly are Omega-3s?

Omega-3 fatty acids are essential fats that belong to a family of essential fatty acids with critical roles in your body, potentially offering numerous health benefits. Moreover, your body cannot produce Omega-3 fatty acids on its own, so you must obtain them from your diet through various natural sources, including fatty fish, fish oils, flax seeds, chia seeds, flaxseed oil, and walnuts. 

What Exactly Are Omega-3 Fatty Acids?

But first, what exactly are they?

As mentioned, Omega-3 fatty acids, often simply referred to as Omega-3s, are essential fats that your body requires for proper functioning. There are three primary types of Omega-3s: ALA (alpha-linolenic acid), DHA (docosahexaenoic acid), and EPA (eicosapentaenoic acid). 

ALA is primarily found in plant sources, while DHA and EPA are predominantly present in marine animals and algae. These Omega-3s play vital roles in ensuring that all the cells in your body function optimally. They are also essential components of cell membranes, providing structural support and facilitating interactions between cells. Although crucial for the functioning of all cells, Omega-3s are particularly concentrated in cells within your eyes and brain.

These essential fatty acids also provide your body with energy and support the health of various body systems, including the cardiovascular and endocrine systems. 

The Potential Benefits of Omega-3

While the research findings present a mixed picture, research suggests that maintaining an adequate intake of Omega-3s can yield numerous health benefits for adults, particularly in the case of the longer-chain forms, EPA and DHA. 

Some ways Omega-3 might act as a factor in the maintenance of good health include:

1. Support Cardiovascular Health

As per the findings in the Singapore Myocardial Infarction Registry Report for the year 2020, there were 11,631 documented cases of heart attacks, signifying a notable increase from the 7,344 cases recorded in 2010. This data translates to an average of 31 heart attack cases per day. Of this group, the mortality rate was 9.2% within the first 30 days following the occurrence of the heart attack. So where and how do Omega-3s come in?

Interestingly, previous observations of communities with diets rich in fish pointed to notably lower rates of these diseases, prompting researchers to investigate the link with Omega-3 consumption.

Omega-3s have shown their ability to contribute to the reduction of triglyceride levels in the blood, which bodes well for heart health. Some older studies even suggest that Omega-3s could increase HDL (good) cholesterol levels, potentially assisting the heart's defence mechanisms.

Omega-3s are also said to play a role in preventing blood platelets from clumping together, reducing the risk of harmful blood clots — an essential aspect of cardiovascular well-being.

2. Support Cognitive Well-being

Your brain, a crucial hub of your body's operations, is composed of approximately 60% fat, with a noteworthy 10% to 20% of that fat being DHA. This isn't just any fat; it fortifies the delicate membranes safeguarding your brain cells, playing a critical role in both short- and long-term cognitive health.

Observational studies hint that diets rich in Omega-3 fats tend to have a reduced risk of cognitive decline. 

Omega-3 fatty acids also serve as custodians of brain function. They're thought to shield brain cells from oxidative stress, which has links to conditions like Alzheimer's disease. 

But that's not all. Omega-3s could be like a friend that stays with you as you grow older, helping preserve your cognitive abilities. A review of 14 studies uncovered their positive impact on various aspects of brain function in older adults. These benefits span from short-term memory to executive function and perceptual speed. Moreover, other studies concluded that Omega-3s could boost blood flow to the brain, potentially enhancing learning, memory, and overall cognitive well-being.

3. Joint Comfort and Flexibility

Omega-3 fatty acids could be a factor in maintaining good joint health and addressing joint pain and stiffness.

This is probably due to their anti-inflammatory properties and capacity to reduce the production of pro-inflammatory proteins within the body. Recent findings from a 2021 study even indicate that Omega-3s hold the potential to address pain in individuals grappling with Osteoarthritis, a form of degenerative joint disease.

4. Mood and Stress Regulation

Research has shown the potential of Omega-3 fatty acids in promoting mental well-being. Supplementation with Omega-3s might provide relief from symptoms of depression and anxiety, with both high and low doses showing efficacy in treating major depressive disorder when compared to a placebo, as indicated by one study.

But that's not all — another study suggests that Omega-3s could potentially enhance the management of anxiety symptoms. Researchers theorise that Omega-3s exert their influence by modulating certain brain pathways responsible for regulating emotions.

While further research is certainly warranted, Omega-3 fatty acids have ventured into the spotlight as potential allies in addressing conditions like schizophrenia, mood disorders, attention deficit hyperactivity disorder (ADHD), and even autism.

Incorporating Omega-3 into Your Life

Now that we've ventured into the realm of Omega-3's potential benefits, let's explore how you can seamlessly weave this essential nutrient into your daily routine:

Natural Sources of Omega-3

  • Fatty Fish: Salmon, mackerel, sardines, and trout are swimming with Omega-3s. Including these fish in your diet a few times a week can be a delectable and heart-healthy choice.
  • Plant-Based Options: If you're following a plant-based diet, consider incorporating flaxseeds, chia seeds, walnuts, and hemp seeds. These sources provide ALA.
  • Algae: Algal oil, derived from algae, is an excellent choice for vegetarians and vegans. It's rich in DHA, the same Omega-3 found in fatty fish.

Now, when opting for Omega-3 supplements, like fish oil supplements, it's crucial to select quality options. Here are some key factors to consider:

  • High Absorption: Look for supplements that offer high absorption rates to ensure your body receives the full benefits.
  • Non-GMO: Ensure that the supplement is free from genetically modified organisms (GMOs) for a more natural choice.
  • All-Natural: Choose supplements made from all-natural ingredients, minimising artificial additives.
  • Gluten-Free: For those with gluten sensitivities or allergies, opt for gluten-free options.
  • Sugar-Free: To maintain a healthy diet, seek sugar-free supplements.

Considering the potential role Omega-3s could play in cardiovascular health, these heart support supplements are worth considering to have added to your regimen. 

Whether you embrace Omega-3-rich foods or opt for supplements, this essential nutrient can become a valuable companion on your journey to attain health. So, explore the world of Omega-3, unlock its potential, and take a step towards a healthier, vibrant you.
