Omega-3 and omega-6 essential fatty acids are vital in any healthy diet.

This is because our body cannot produce them and because they are basic components of the structure of our cells.

You may have never heard or thought about them until now. In fact, even as important as they are, many people still tend to forget about them. Essential fatty acids a re usually found in fats, specifically those in:

A lot of people are afraid of eating healthy fats because they’re afraid they’ll literally “make them fat.” But in reality, y our body needs a regular dose of these healthy fats.

Omega-3 and 6: What Are Essential Fatty Acids?

We know that there are plenty of products that are artificially enriched with omega-3 and omega-6 out there nowadays.

There are smoothies, as well as different kinds of milk and butter with these added components.

This helps and we can’t deny it. However, given that your body doesn’t produce these essential fatty acids, the ideal option is to go for natural sources like salmon, nuts, linseed, and broccoli.

  • Linoleic acid (omega-6) is the most well-known long-chained fatty acid, which is mostly found in all types of seeds, dried fruits, and oils such as sunflower oil.
  • On the other hand, you can find omega-3 fatty acids in oily fish, seafood, legumes, olive oil, nuts, and almonds.

Both omega-3 and omega-6 fatty acids are structural components of cellular membranes and are needed for an infinite number of organic processes.

They are also an important energy source for your body.

Signs That You’re Deficient in Omega-3 and 6 Fatty Acids

1. Dry Skin

Without a doubt, one of the most typical  clinical signs of a deficiency of essential fatty acids is dry skin.

This is very common in young children if they do not get enough of these fatty acids in their diets.

Skin problems are often a direct result of not getting enough omega-3 and omega-6. When this occurs, you are more susceptible to infections and wounds take longer to heal than usual.

2. Premature Births

The causes of the increase in rates of premature births are not precisely clear. However, f actors such as the mother’s age, tobacco use, stress and low levels of omega-3 and omega-6 could be some of the triggers.

These essential fatty acids favor the correct development of the fetus during pregnancy.

They’re comparable to high-quality “gasoline” that ensures correct cell function and the “assembly” processes that are necessary for a baby to reach full term.

Diet is obviously key during pregnancy, and elements such as vitamin D, calcium and essential fatty acids are undeniable allies.

3. Heart Problems

Eating foods rich in omega-6 helps has an incredible protective effect on your heart. They provide energy and may help reduce cholesterol, as well as triglycerides.

On the other hand, omega-3 fatty acids could help reduce the risk of suffering from thrombosis and aid in reducing the growth of atherosclerotic plaque. They can also help regulate inflammation.

It’s important to keep this in mind and try to consume these natural sources of essential fatty acids regularly.

4. Extreme Fatigue

When we say inflammatory diseases, we are talking about rheumatoid arthritis, for example.

The main virtue of foods rich in omega-3 fatty acids is that they can relieve inflamed joints and morning stiffness. They may help reduce swelling and pain, and can potentially be effective natural anti-inflammatories.

However, remember that it’s important to eat them daily. You’ll only reap the benefits if you’re consuming them consistently.

In conclusion, we’re sure that you’ve heard about omega-3 and omega-6 on multiple occasions.

However, it’s important to remember that this isn’t about a trendy way of eating. It’s about maintaining your well-being and quality of life.
