omega 3s food for longevity

Study Finds Consuming This One Nutrient Is Linked To Living Longer: These Are the Top 5 Food Sources

Have you ever thought about how incorporating omega 3 in your diet could enhance your life? 

Omega 3 fatty acids are being studied to identify the link between longevity (aging in better health) and cardiovascular health (1, 2). 

What Is Omega 3?

Omega 3 fatty acids are a type of essential fat. 

Essential fats are not made by the body but obtained through our diet. 

This fatty acid is needed to perform many functions within our body. Such as controlling blood clotting and building cell membranes in our brain (3). 

A positive effect of this fatty acid is that it helps reduce inflammation.

This decreases the risk of heart disease, along with helping other inflammatory conditions such as asthma, Alzheimer’s disease, and dementia (4). 

“Omega-3 fatty acids, for example, help build and repair brain cells, and antioxidants reduce cellular stress and inflammation, which are linked to brain aging and neurodegenerative disorders, such as Alzheimer’s disease” (4). 

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

ALA is found in some vegetable oils, nuts, seeds, and soy foods. While EPA and DHA are found in fatty fish, eggs, and organ meats. 

You can incorporate an omega supplement; however, it is advised to incorporate a food-first approach when possible.

If you are incorporating a supplement, please work with your medical team to identify what will be best for you. 

Weekly servings of omega-3 play a role in cardiovascular health and may be helpful with reducing cognitive impairment, age-related memory loss, and potentially reducing the risk of Alzheimer’s however more research is needed (5). 

5 Top Food Sources for Omega 3s (Fatty Acids)

With a variety of seafood options, you can incorporate a balanced diet while getting high levels of omega-3 which may assist in reducing memory problems and may increase cognitive function. 

However, additional studies are needed with long-term clinical trials to identify a person’s chances of decreasing their dementia risk through dietary changes. 

2. Soybeans

Can be eaten in the form of tofu as well.

3. Seeds

Top choices include sesame seeds, ground flax seeds, and chia seeds.
