What are Omega 3 Fatty Acids?

Omega-3 fatty acids are a type of polyunsaturated fat that plays a crucial role in maintaining overall health. 

These essential fats are not produced by the body and must be obtained through diet or supplements.

There are three main types of omega-3 fatty acids: alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). 

ALA is found in plant-based sources such as flaxseeds, chia seeds, hemp seeds, walnuts, and soybeans. ALA needs to be converted to EPA and DHA in the body before being utilized.

EPA and DHA, on the other hand, are primarily found in fish and algae.

According to expert recommendations, adult men above the age of 19 years should take 1,600mg, while adult women should aim for 1100 mg daily.

The Benefits of Omega-3 Fatty Acids:

1. Maintains Heart Health

A significant body of research has shown that consuming omega-3 fatty acids can benefit heart health in various ways, including lowering the risk of developing heart disease. 

One of the reasons for this is the omega 3s ability to reduce inflammation, the root cause of most chronic conditions, including heart health.

Omega-3 fatty acids can also help lower blood pressure, another risk factor for developing heart disease and stroke.

In addition, these healthy fats can help improve endothelial functions. The endothelium is the inner lining of your blood vessels and is responsible for the production of nitric oxide, a compound that relaxes blood vessels and promotes dilatation.

This improved function supports healthy blood flow, reduces arterial stiffness, and reduces blood pressure, all of which can lower the risk of cardiovascular diseases.

Some studies also show that omega 3s can lower triglycerides, another risk factor for heart disease.

Despite all these benefits, no current evidence shows that omega-3 fatty acids can prevent strokes or heart attacks. So, in addition to consuming omega-3 fatty acids, considering other healthy lifestyle habits is essential.

2. Boosting Cognitive Performance

Omega-3 fatty acids, especially docosahexaenoic acid (DHA), are vital components of the brain cell membranes. 

They contribute to improved communication between neurons, which enhances cognitive functions such as memory, attention span, and problem-solving abilities.

3. Supporting Brain Development

During pregnancy and early childhood, omega-3 intake becomes even more critical as it supports the growth and development of the fetal and infant brains. 

DHA accumulates rapidly in these critical periods, significantly impacting neural tissue formation.

4. Reducing the Risk of Mental Decline

Studies have shown that regular consumption of omega-3 fatty acids may help lower the risk of age-related mental decline or neurodegenerative diseases like Alzheimer’s disease. 

The anti-inflammatory properties of omega-3s may protect against oxidative stress and decrease inflammation in the brain, both of which can contribute to cognitive decline.

5. Alleviating Symptoms of Depression

Research suggests that omega-3 supplementation can be beneficial for individuals experiencing symptoms of depression or other mood disorders. 

The fatty acids help regulate neurotransmitter activity in areas associated with mood regulation, potentially improving depressive symptoms.

6. Enhancing Focus and Attention

Omega-3s have been found to enhance focus and attention in both children and adults alike. 

This allows individuals to concentrate better on tasks at hand while maintaining mental clarity throughout the day.

7. Improving Sleep Quality

Insufficient sleep or poor sleep can cause various health issues, including increased levels of the stress hormone cortisol, a weakened immune system, and even weight gain.

However, incorporating plant-based omega-3 fatty acids into your diet can help you sleep better each night.

According to research, omega-3 can improve sleep quality by increasing melatonin production in the brain. Melatonin is a sleep hormone that signals the brain when it’s time to sleep. It also helps regulate the sleep and wake cycle, thus maintaining a regular sleep pattern.

8. Omega-3s Can Regulate Mood

Maintaining a positive mood is essential for overall well-being, and recent research suggests that omega-3 fatty acids may significantly enhance your emotional state.

For one, omega-3 fatty acids are known to boost serotonin levels. Serotonin is often referred to as the “feel-good” neurotransmitter because it helps regulate mood and emotions. Omega-3 fatty acids help increase serotonin production in the brain, leading to improved mood and reduced symptoms of depression.

Also, these fats help fight brain inflammation, which has been linked to various mental health disorders like depression and anxiety.

Additionally, high levels of stress can significantly impact your mental state and lead to feelings of anxiety or irritability. Omega-3 fatty acids help regulate the body’s stress response by reducing cortisol levels (the primary stress hormone). This regulation helps counteract the negative effects of chronic stress on your mental well-being.

9. Eye Health

DHA is an integral component of the retina in our eyes. Adequate intake of omega-3s helps maintain good vision by preventing macular degeneration (a leading cause of blindness) and reducing dry eye syndrome.

10. Skin Health

Omega-3s contribute to maintaining healthy skin by supporting its structure, improving hydration, and reducing dryness and itching. 

They also aid in managing various skin conditions like acne, eczema, and psoriasis due to their anti-inflammatory effects.

11. Bone Health

Omega-3 fatty acids have been shown to enhance calcium absorption in the body. This mineral is a crucial component of bone structure and strength.

Additionally, research suggests that omega-3s may help slow down the process of bone loss associated with aging or conditions like osteoporosis.

Omega 3 fatty acids have also been shown to enhance vitamin D activation. Vitamin D is essential for calcium absorption and utilization by the bones, thus ensuring optimal bone health.

Research shows that without enough vitamin D, the body cannot absorb more than 10-15% of your dietary calcium.

Sources of Plant-Based Omega-3 Fatty Acids

Plant-based omega-3 fatty acids are a great alternative to the traditional fish sources of omega-3, especially for vegans and anyone on a plant-based diet.

1. Flax Seeds

Flax seeds boast one of the highest concentrations of omega-3 fatty acids among plant-based foods.

These tiny powerhouses contain alpha-linolenic acid (ALA), which is converted into eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) – the two main types of omega-3s found in fish oil. In fact, up to 50% of flax seed weight is from ALA.

While it is true that fish remains an excellent source of EPA and DHA directly absorbed by our bodies, studies indicate that ALA from flax seeds and other plant sources can still be effectively converted to EPA and DHA within reasonable limits when consumed regularly.

Adding flax seeds to your diet is also simple and versatile.

They can be consumed in various forms, such as whole seeds, ground flaxseed meal, or even as flaxseed oil. Sprinkle them on top of cereals, yogurt, and salads, or blend them into smoothies for an easy omega-3 boost.

2. Chia Seeds

Similar to flaxseeds, chia seeds are packed with ALA omega-3s and provide other vital nutrients like fiber and protein.

One ounce of chia seeds contains approximately 5 grams of ALA, about 5000 mg of omega-3. This is more than the daily recommended amounts.

Chia seeds can also offer additional nutrients, including fiber, protein, and antioxidants like quercetin, kaempferol, and caffeic acid

One popular way to consume chia seeds is by mixing them with liquid such as water or plant milk. Add two tablespoons of chia seeds to one cup of liquid and let it sit in the refrigerator overnight. Top it with fruits, nuts, or honey for added flavor.

Another simple method is sprinkling dry chia seeds onto salads or adding them to yogurt for some added crunch and nutritional benefits. Make sure to chew them well to release their beneficial compounds.

3. Hemp Seeds

Hemp seeds are the edible part of the hemp plant. Although they come from the same species as marijuana (Cannabis sativa), they do not possess psychoactive properties and are completely safe for consumption.

These seeds have a mild nutty flavor and can be found in different forms such as whole seeds, shelled (hulled) seeds – commonly known as hemp hearts – or even as oil.

Hemp seeds contain an ideal balance of omega-6 to omega-3 fatty acids, typically ranging from 2:1 to 3:1 ratio – which is considered nutritionally beneficial.

A serving size of approximately three tablespoons (30 grams) of hemp hearts contains around 11 grams of polyunsaturated fats, including both omega-6 and omega-3 fatty acids, of this total fat content.

A few ways to incorporate hemp seeds into your diet include sprinkling a tablespoon as a topping to your salads, yogurt bowls, or smoothies for an extra crunch and nutty flavor.

4. Seaweed

Seaweed, also known as macroalgae, is a diverse group of marine plants that thrive in saltwater environments. It serves as a vital source of nutrition for various sea creatures, including fish.

This nutrient-rich plant contains an abundance of vitamins, minerals like iodine and magnesium, antioxidants, and, most importantly for our purposes – DHA and EPA omega-3 fatty acids.

Fish is a good source of these beneficial fatty acids by consuming algae directly or indirectly through the food chain.

Similarly, by consuming seaweed directly instead of relying on fish oil supplements, you can help meet your requirement and, as a result, reduce overfishing practices.

Seaweed comes in different colors, including green (such as nori), red (e.g., dulse), brown (like kelp), and even blue-green varieties like spirulina.

If you’re new to seaweed, start by trying it in small amounts. You can add seaweed to soups and stews or use it as a wrap for sushi. Seaweed is also a great way to add flavor and nutrition to salads. Just be sure to rinse it thoroughly before eating.

5. Brussels Sprouts

Brussels sprouts are often overlooked when it comes to their nutritional value. These small, cruciferous vegetables resemble miniature cabbages and offer an impressive array of health benefits. One notable aspect is their omega-3 fatty acid content.

While brussels sprouts may not be the first food that comes to mind when considering omega-3 sources, they contain a moderate amount of these beneficial fatty acids. 

On average, one cup (156 grams) of cooked brussels sprouts provides approximately 170 milligrams (mg) of alpha-linolenic acid (ALA).

6. Walnuts

Walnuts not only add crunch and flavor to your meals but also serve as a great source of ALA omega-3 fatty acids among nuts.

It offers an excellent alternative for individuals following plant-based or vegan diets who may struggle to incorporate adequate amounts of DHA and EPA into their nutrition plans. 

By choosing algal oil supplements derived directly from algae sources rather than animal-derived products like fish oil capsules, vegans can effortlessly meet their omega-3 requirements.

Moreover, algal oil is one of the purest sources, unlike fish oils, which may contain impurities such as heavy metals or environmental toxins due to pollution in oceans and water bodies.

Algal oil supplements are commonly available as soft gels, with each containing about 400-500 mg of combined DHA and EPA. Experts recommend a daily intake of 300-900 mg of DHA and EPA combination per day.
