Are Omega-3 Fatty Acids Good For You

Omega-3 fatty acids are highly essential for our overall health.  They are present in foods and dietary pills. They also have an active role in our proper metabolic functioning. There are three main types of omega-3 fatty acid; alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)

ALA is rich in plant oils, like flaxseeds and walnuts. DHA and EPA are most abundant in cold-water fatty fish, like trout mackerel, tuna, herring, and sardines. Your body may change small amounts of ALA into DHA and EPA.  From the view of the Office of Dietary Supplements (ODS), a large number of individuals in the USA get enough ALA in their food source.

What Are Omega-3 Fatty Acids

These are a kind of polyunsaturated fatty acids that are present in food. These are essential fatty acids (EFAs) as your body can not synthesize these fatty acids. Two important kinds of omega-3 fatty acids are EPA and DHA. These two forms of omega-3s are present in fish.

Plants like nuts and seeds have another form of omega-3 fatty acids, ALA(alpha-linolenic acid). These fatty acids are much needed for the proper functioning of the body.

The Importance of Omega 3 Fatty Acids

  1. Improvement of Brain Health

Omega 3 fatty acids are essential for proper brain growth and development in infants. DHA comprises 40% of the polyunsaturated fatty acids in your brain and almost 50% in the retina of your eye. That is why infants who are given DHA-fortified formula have excellent eyesight. If a pregnant woman takes the right amount of omega-s, her child will have numerous health benefits such as,

  • Better communication skills
  • Fewer behavioral problems
  • Higher intelligence
  • Minimum risk of developmental delay
  • Decreased risk of ADHD, autism and cerebral palsy


  1. Fight against Inflammation

Inflammation occurs as a result of infection or injury. In this way, it is crucial and necessary for the body.

Sometimes inflammation remains for a long time without any infection. This type of inflammation is called chronic inflammation. Chronic inflammation can be the cause of heart diseases and cancer.

To fight this problem, you have omega-3 fatty acids, which can decrease the generation of those compounds that can cause inflammation, such as inflammatory cytokines and eicosanoids.

Studies prove this fact that more intakes of omega-3 fatty acids reduce inflammation.

  1. Cure of Depression

Researchers say that people with high levels of omega-3s have a decreased level of depression. Therefore it may be suggested that one should take these fatty acids to treat depression and other mood disorders. It is believed that omega-3 fatty acids can easily cross the brain cell membrane and affect the brain's mood-related substances. Due to their anti-inflammatory property, they can cure depression.

  1. Weight Loss

A person with a BMI (body mass index) of more than 30 is obese. Almost 40% of adults are overweight, while 15% are obese.

Obesity can cause numerous health problems like cancer, heart diseases, and type 2 diabetes.

Omega-3 fatty acids can help to improve health and decrease the risk of heart diseases in obese people.

Some studies show that omega-3 fatty acids, along with proper diet and workout, can help to reduce weight.

  1. Healthy Skin

Skin is the largest organ of your body. It has an abundant quantity of omega-3 fatty acids. Skin health can be affected by too much exposure to the sun but more specifically with old-age. Taking omega-3 fatty acids can prevent several skin problems such as dermatitis and psoriasis.

Studies say that psoriasis can be due to a reduced amount of DHA and EPA.

Omega-3 fatty acids can significantly reduce the symptoms of eczema. This is because these fatty acids fight the cause of eczema, leukotriene B4.

  1. Cardiovascular Disorders

It has been seen that omega-3 fatty acids can prevent cardiac arrhythmias and many other coronary heart diseases. They can treat hypertension and hyperlipidemia.

These fatty acids can lower the triglyceride level in your body. People with greater levels of triglycerides are at higher risk of heart disorders such as heart attacks.

  1. Metabolic Syndrome

Metabolic syndrome consists of many disorders like central obesity, hypertension, and insulin resistance.

It is a significant health issue as it causes so many other issues, such as diabetes and heart problems.

Omega-3 fatty acids can treat insulin resistance and other symptoms of metabolic syndrome.

  1. Autoimmune Disorders

In autoimmune disorders, your immune system kills healthy cells of your body. Type 1 diabetes is an essential example in which insulin-producing cells are affected. Omega-3 fatty acids can treat many such disorders, especially during early life.

These fatty acids can cure ulcerative colitis, multiple sclerosis, Crohn's disease, and psoriasis.

  1. Bone Health

Osteoporosis and arthritis are common disorders of the skeletal system.

Researches show that omega-s plays a vital role in maintaining bone health by increasing calcium levels in bones. Therefore it minimizes the risk of osteoporosis.

These fatty acids can also cure arthritis. Intake of omega-3 fatty acids results in a reduction in joint pain and better grip strength.
