Fish oil or omega-3 fatty acid is a dietary supplement responsible for maintaining overall health. Fish oil is extracted from fish tissues of herring, tuna, anchovies, mackerel, and cod liver oil.

Two types of omega-3 fatty acids like EPA and DHA, can be obtained from fish oil, which is what makes it so vital to know what fish oil actually is. The plant-based fatty acid is mainly alpha-linolenic acid (ALA).

However, ALA is only fatty acid while EPA and DHA contain most of the health benefits. EPA and DHA are responsible for reducing inflammation and improving cognitive health, behavioral factors, and mood.

Although in the recent diet, most omega-3 has been replaced with omega-6 and other fats.

Differences Between Omega-3 And Omega-6 And Other Fats? 

There are some distinct characteristics of omega-3 fatty acids, such as, 

  • Omega 3’s are essential fat required for the development of cell membranes.
  • The omega-3 fatty acid has been responsible for reducing inflammation and supporting brain development, and various other benefits on autism.
  • The omega-3 fatty acid has been linked with improving mental health conditions in autistic children.

The omega-6 fatty acid has been responsible for contributing to factors such as, 

  • The omega-6 fats are used for inducing energy.
  • Omega-6 cat is pro-inflammatory when consumed in large amounts.
  • Sources of omega-6 fatty acids are refined oils, including soybean, mayonnaise, and corn oil.

Other fats and omega-9 fatty acids are characterized as, 

  • Omega-9 fatty acids are produced in our body, these fatty acids are not required.
  • Omega-9 fatty acid sources are olive oil, avocado oil, cashews, and almonds.
  • Omega-9 fatty acids also have certain health benefits, including helping to improve metabolic health.

How Diet Is Related To Autism? 

Autism or autistic spectrum disorder (ASD) is a range of neurodevelopmental conditions related to the faulty development of the nervous system, which results in difficulty in communicating, socializing, interacting, and repetitive behaviors.

Effect Of Omega-3 Fish Oil on Autism

The deficiency of omega-3 fatty acids in the uterus during pregnancy can lead to autism in children in some cases.

According to the research, autistic children suffer from a lower level of omega-3 fish oil in the body. Mothers with low levels of DHA also pose a chance that their babies will have poor visuals and neural development.

Omega-3 fish oil supplements in autistic children solve various brain-related disorders such as cognition, mood, and behavior. Almost 60% of human brain components are fats which are required for maintaining the essential functionalities of the brain.

As per various studies, omega-3 fish oil facilitates the structural development of the brain, which enhances mental and cognitive abilities.

Various Sources Of Omega-3 Fatty Acid 

The animal-based omega-3 fatty acid is extracted from fish tissues and liver oil in most cases. However, apart from animal sources, the omega-3 fatty acid is also present in plants.

Flax Seeds 

Flaxseed extracts can be used as flaxseed oil which is an essential source of omega-3 fatty acid named alpha-linolenic acid (ALA). The alpha-linolenic acid (ALA) has anti-inflammatory factors, which can reduce swelling in case of inflammation due to rheumatoid arthritis.

Flaxseed oil is also used in patients suffering from heart disease, high blood pressure, and high levels of cholesterol. Flaxseed oil is easily digestible and can be taken by mixing it with yogurt as dressings.

Among all the other nuts, walnuts have a significant amount of ALA content. ALA has an anti-inflammatory factor and improves the mental well-being of autistic children.
