Why does our body need omega-3? Effects and benefits

Omega-3 fatty acids are among the most important supplements available. Since our bodies cannot produce them on their own, we need to obtain these silent heroes from our diet or various supplements. Why are these essential fats so crucial for our bodies, and how can we acquire them?

Introduction to Omega-3

Omega-3 fatty acids are essential fats necessary for our health, but our bodies cannot produce them on their own. Therefore, they must be obtained from either our diet or supplements. These fatty acids play a key role in many areas of our health, from supporting the cardiovascular system to improving brain and eye health.

There are three main types of omega-3 fatty acids important for us:

  • EPA (Eicosapentaenoic Acid): This acid is found primarily in fish and has strong anti-inflammatory effects. It also helps lower blood triglyceride levels and supports heart health. Elevated triglyceride levels increase the risk of atherosclerosis, which is a common cause of deadly cardiovascular diseases like heart attacks and strokes.

  • DHA (Docosahexaenoic Acid): This acid is crucial for healthy brain and eye development and function. It is most present in the brain and retina and plays a vital role in cognitive functions and visual health.

  • ALA (Alpha-Linolenic Acid): This third acid is mainly found in plant sources such as flaxseeds, chia seeds, and walnuts. The body can partially convert it into EPA and DHA, but this process is not very efficient.

Why Do We Need Omega-3?

  • Support for Heart Health: As mentioned, omega-3 fatty acids can help reduce blood triglyceride levels. This contributes to the prevention of heart disease and can also lower blood pressure and improve blood vessel function.

  • Brain Health and Cognitive Function: DHA is important for the structure and function of the brain. Omega-3 fatty acids can enhance cognitive functions such as memory and attention. They may also have a positive impact on mood and help prevent depression.

  • Anti-Inflammatory Effects: Omega-3 fatty acids have anti-inflammatory properties that can assist in the treatment of various inflammatory conditions.

  • Support for Eye Health: DHA is also important for eye health. It can help protect vision and guard against certain eye problems, such as age-related macular degeneration, which is a common cause of vision loss in older adults.

  • Skin Health: These fatty acids can also help maintain healthy and hydrated skin. They can improve skin elasticity and assist with skin issues such as eczema or acne.

  • Support for Pregnancy Health: Interestingly, omega-3s influence pregnancy and breastfeeding. During this time, the importance of consuming adequate amounts of omega-3 fatty acids increases. They support the development of the brain and eyes in the fetus and can reduce the risk of certain complications during pregnancy.

How to Obtain Enough Omega-3?

Since omega-3 fatty acids need to be supplemented because our bodies cannot produce them, there are several ways to achieve this:

Diet Rich in Omega-3

The most common and natural way to supplement omega-3 fatty acids is to include foods rich in these acids in your diet.

  • Fatty Fish: Salmon, mackerel, and sardines are excellent sources of omega-3.
  • Seeds and Nuts: Flaxseeds, chia seeds, and walnuts contain ALA, a plant-based source of omega-3.
  • Plant Oils: Flaxseed, chia, and hemp oils are also rich in ALA.

Omega-3 Supplements

It is likely that even if you include some of these foods in your diet, it may not be sufficient. While you'll have enough ALA, you'll still need to supplement with DHA and EPA. Sources for these are specific marine algae, and the easiest way to obtain these acids is by consuming fatty marine fish that eat these algae. If you include these fish in your diet at least twice a week and also consume foods rich in ALA, you are less likely to be deficient in omega-3s. However, if you prefer freshwater fish or do not eat fish at all, you should consider supplementation with omega-3 fatty acids.

Fish oil is a popular choice and might even be a nostalgic memory from your youth. However, it contains adequate amounts of EPA and DHA. Today, it is fortunately easier to manage, with various products available that simplify dosing, such as capsules.

Summary

Omega-3 fatty acids are crucial for maintaining health on many levels. Although our bodies cannot produce these essential fats on their own, there are many ways to obtain them through diet and supplements. If you prefer not to monitor your diet to ensure you get enough of these acids, supplements can be a useful option.
