Omega-3 Fatty Acids

The body can synthesise fats from a variety of food sources. Omega-3 fatty acids, on the other hand, are essential fats for human survival. These fatty acids can only be obtained from specific foods. This incredible essential fat can be found in a variety of foods, including vegetable oil, fish, walnuts, green leafy vegetables, and so on.

Omega-3 fatty acids are required by the body. They can be found in the human system’s cell membranes. They are in charge of regulating the function of cell receptors. Hormones that aid in blood clotting, inflammation, contraction, and relaxation of the artery walls in the heart, for example, are synthesised in the body using omega-3 fatty acids.

These polyunsaturated fats are classified into three types:

  • Alpha-linolenic acids (ALAs) (ALA)
  • Eicosapentaenoic acid (EPA)
  • Docosahexaenoic acids (DHAs) (DHA)

ALA can be found in foods such as walnuts, flax seeds, and chia seeds. It is used as energy by the human body. Only certain types of fish, such as salmon, mackerel, and sardines, contain EPA and DHA. They are also commonly referred to as “Marine Omega-3s.”

The Health Benefits of Omega-3 Fatty Acids

Promotes Heart Health

According to one study, 17.9 million people worldwide die each year as a result of heart disease. The main cause of cardiac diseases is an increase in triglyceride levels.

Omega-3 fatty acids are helpful in lowering the risk of cardiovascular disease, such as heart stroke. Consuming omega-3 fatty acids, according to research, lowers triglyceride levels and reduces inflammation in the body. Furthermore, it improves blood vessel function and increases blood flow.

Helps to Reduce Inflammation

Inflammation is our body’s natural response to infections in order to protect our organs from damage. However, if inflammation occurs in the absence of a prevalent infection, it can have serious consequences for your health.

Omega-3 fatty acids can aid in the reduction of cytokines in our bodies, which contribute to inflammation. According to research, including fish oil in one’s diet can significantly reduce inflammation in people with rheumatoid arthritis. Fish oil is high in omega-3 fatty acids.

Reducing Depression and Anxiety

An estimated one-fourth of the world’s population is affected by mental health disorders such as anxiety and depression.

People suffering from depression may exhibit symptoms such as loss of interest in daily activities, excessive sleeping, feelings of hopelessness, and so on.

According to one study, omega-3 fatty acids can help reduce symptoms associated with mental health problems. EPA is the most effective in combating mental health disorders of the three major categories of omega-3 fatty acids.

Improves the brain health of both the infant and the mother during pregnancy

Omega-3 fatty acids improve the brain health of pregnant women and infants. This is due to the high concentration of DHA found in the brain and retina. Furthermore, according to one study, infants given DHA had better eyesight than others. In addition, there are several other advantages for the child, such as:

  • Autism, ADHD, and Cerebral Palsy risk are all reduced.
  • Social and communication abilities that are well developed
  • Smaller behavioural issues
  • Higher IQ scores

Protection Against Autoimmune Diseases

By attacking foreign cells, our immune system protects us from disease. However, it occasionally misidentifies healthy cells as unwanted cells and begins attacking them.

The exact cause of these autoimmune diseases is unknown, but they are caused by genetic factors. Diabetes type 1 is a well-known example of such a disorder.

According to one study, consuming omega-3 fatty acids in your early life can help you avoid autoimmune diseases such as diabetes.

Enhances Brain Health

There is a decline in mental health among older adults. It occurs as a result of the deterioration of brain function that occurs with age. Consuming omega-3 fatty acids during the onset of Alzheimer’s disease, according to one study, can help prevent its symptoms.

This is due to the fact that omega-3 fatty acids are neuroprotective and improve cognitive abilities. As a result, it is advised to consume it in order to maintain good mental health and regulate emotions.

Beneficial to Bone and Joint Health

After the age of 40, bone density decreases due to ageing and other factors. As a result, eating omega-3-rich foods can help meet the bones’ calcium requirements. This reduces the risk of osteoporosis and arthritis. According to one study, people who ate omega-3 fatty acids had less joint pain and better bone health.

Inflammation is another common problem that can lead to bone weakness. Omega-3 fatty acids have also been shown to help with this issue.

Promotes Healthy and Glowing Skin

DHA is the main component of the skin’s structure. It is in charge of maintaining the health of cell membranes. The skin is soft, radiant, and acne-free when the cell membrane is healthy. Furthermore, EPA has a number of advantages for achieving spotless skin.

According to one study, consuming omega-3 fatty acids can aid in the prevention of acne and the management of excessive oil production in the skin. It also keeps your skin smooth and hydrated and prevents premature skin ageing.

Reduce Your Cancer Risks

According to data, more than 9.5 million people die each year as a result of cancer. Omega-3 fatty acids are extremely beneficial and aid in the prevention of cancer risk factors.

For example, studies show that people who consumed omega-3 fatty acids had a 55% lower risk of developing colon cancer. It also reduces the risk of men developing prostate cancer and women developing breast cancer.[1]

Provides Better Sleep

Proper sleep, in addition to a well-balanced diet, is essential for living a healthy lifestyle. According to a study on sleep deprivation, inadequate sleep is the leading cause of diabetes, depression, and obesity. Furthermore, in adults, low omega-3 fatty acid levels cause sleep apnea and obstructive sleep apnea.

Melatonin levels are reduced when DHA levels are reduced. It is a hormone that regulates people’s sleeping patterns. Several studies suggest that omega-3 improves sleep quality and duration. As a result, both children and adults should take omega-3 supplements.
