how omega-3 fish oil helps your brain and has other benefits

Fish has long been a nutritionally valued part of diets around the world, and a closer look reveals why it’s so good for our brain!

Have you ever heard parents tell their children that “fish is brain food”? This isn’t just a clever tactic to get them to clean their plates – it turns out there is science behind the saying in terms of the valuable nutritional benefits specific to fish.

Fish has been a valued part of traditional diets across the globe for thousands of years, and regular fish consumption is encouraged as a part of a healthy diet. Not only is it an excellent source of protein, vitamins and minerals, but it also contains omega-3 fatty acids – valuable polyunsaturated fats that are essential to the human body, meaning that we need to get them through dietary sources.

The Nourishing Fats of Fish

The two omega-3s that relate to the brain are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fats are found in abundance in fish like mackerel, salmon, sardines, anchovies, and herring.

What also makes fish such a valuable source, is that there aren’t many other dietary sources so rich in EPA and DHA. While there are plant sources that contain alpha-linolenic acid (ALA) which can be converted to EPA and DHA, like walnuts, flaxseed, hemp seed, chia seeds and soybean oil, some research has found that the conversion rate isn’t very efficient, with only a small percentage becoming EPA or DHA.

Still, many people find it hard to frequently incorporate fish into their diets in recommended quantities and are still falling short of getting enough EPA and DHA. This is where omega-3 fish oil supplements come in to play as a convenient and effective supplement!

Fish Oil and The Brain

It’s no wonder that fat plays a key role in brain structure – the brain itself is close to 60% fat! EPA and DHA can be found in the membranes of brain cells, helping to support cellular integrity, as well as facilitate communication between brain cells. Researchers have explored the relationship between omega-3 fish oil and memory, cognition, and in various stages of degenerative cognitive conditions with promising results.

Studies have found that omega-3 fish oil has positive effects in supporting cognitive health and brain function, when supplementing daily with an omega-3 fish oil containing 100-5,000 mg EPA and DHA including at least 100 mg DHA.

There’s also the emotional side of the brain, and there’s no doubt that nutrition has an effect on mood. Taken alongside a healthy diet, omega-3 fish oils with a higher ratio of EPA to DHA (2:1), containing at least 1000 mg EPA can also help to promote healthy mood balance.

Cardiovascular health

Daily supplementation of omega-3 fish oils has been associated with positive effects on blood pressure and reducing serum triglycerides. Dosages of 200-5,000 mg EPA and DHA have been found to help maintain and support cardiovascular health with a ratio of EPA:DHA between 0.5:1 and 2:1.

Pain relief in rheumatoid arthritis

Higher doses of EPA and DHA (2,800-5,000 mg EPA and DHA) have been found to be an effective complement to conventional therapies in reducing pain associated with rheumatoid arthritis.

Everyday health

Supplementing daily with a quality fish oil containing 100-5,000 mg EPA and DHA can help with the maintenance of good health – a great preventative approach that can help protect wellbeing.

Choosing Your Omega-3 Fish Oil

When looking at omega-3 fish oil labels – it can get a little confusing.

What you’re looking for is the amount of EPA and DHA in the dosage (e.g. 5 ml, 4 capsules), as well as the ratio of EPA:DHA. For example, if a formula contains 400mg of EPA and 100mg of DHA per serving – you’re looking at a 4:1 ratio of EPA:DHA. We can help you find the omega-3 concentration you’re looking for, as well as help you navigate labels.

Make sure the bottle or packaging has an eight-digit NPN# to ensure it has been approved by Health Canada for safety and efficacy. You can also look up the number on the Health Canada website to view the product’s approved health claims and research.

Another thing to be aware of is purity and ensuring that the oil is free of contaminants. Always read labels carefully and reach out to manufacturers with any questions.

Like many natural health supplements, if you have a pre-existing condition, are pregnant or are currently taking other medications, be sure to consult with your health care professional.
