Omega 3 Acids: Why Are They Necessary In Your Diet?

Essential fatty acids include omega-3 fatty acids. Though the body is unable to produce them, they are required for human health. You will have to entice them with food.

Fish, such as halibut, salmon, and tuna, as well as different kinds of seafood like krill and algae, nut oils, and plants, contain omega-3 fatty acids.

An omega-3 fatty acid is also known as a polyunsaturated fatty acid. They are essential for optimal development and growth, and brain function.

They have also increased in popularity due to their potential in lessening the risk of heart disease.

Omega-3 fatty acids have been found in studies to reduce inflammation. It might also help in reducing the risk of chronic diseases, such as arthritis, heart disease, and cancer.

Omega-3 fatty acids are quite abundant in the brain. They have a vital role in behavioral function, cognitive, and memory performance.

Infants who do not receive adequate omega-3 fatty acids from their mothers during pregnancy are more likely to develop neurological and visual disorders.

Poor circulation, poor memory, fatigue, sadness, heart problems, dry skin, and mood swings are symptoms of omega-3 fatty acid insufficiency.

In this article, we will be looking at types of omega 3 acids, their benefits, risks associated with them, and their dosage.


Types Of Omega 3 Acids

Dietary supplements and foods contain omega-3 fatty acids. They aid in the proper functioning of the membranes which enclose every cell of the body.

Omega-3 fatty acids are divided into three categories:

  • Docosahexaenoic acid (DHA).
  • Alpha linolenic acid (ALA).
  • Eicosapentaenoic acid (EPA).

Cold water fatty fish, such as sardines, salmon, mackerel, and herring are high in EPA and DHA. Plant oils, such as walnuts, chia seeds, and flax seeds are high in ALA.

Most people in the United States get enough ALA in their diet, according to the Office of Dietary Supplements (ODS).

Little amounts of ALA might be converted into EPA and DHA by the human body. Experts often debate on how much EPA and DHA a person requires.

Benefits Of Omega 3 Acids

Here are some of the Omega 3 benefits:

  1. Healthy Brain During Pregnancy And Childhood

    Omega-3 fatty acids are essential for a baby’s brain growth and development.

    DHA makes up 35% of the polyunsaturated fatty acids in your brain and 65% of the polyunsaturated fatty acids in your retina.

    Therefore, according to research, it is no surprise that newborns who are fed a DHA-fortified formula have stronger eyesight than those who are not.

    Getting enough omega-3s during pregnancy is linked to a slew of advantages for your baby, including:

    • Better communication and social skills.
    • A higher level of intelligence.
    • Cerebral palsy, ADHD, and autism risk are reduced.
    • There are fewer behavioral issues.
    • Reduced chance of developmental delay.
  2. Helps With Metabolic Syndrome Symptoms

    A metabolic syndrome is often a group of symptoms.

    Low HDL cholesterol levels, insulin resistance, high blood pressure, and high triglycerides are part of it.

    It is a serious public health issue as it raises your chances of getting a variety of different ailments, such as diabetes and heart disease, according to studies.

    In persons having metabolic syndrome, omega-3 fatty acids might help with heart disease, insulin resistance, and inflammation risk factors.

  3. Age-Related Mental Illness

    Alzheimer’s Disease is one of the unavoidable consequences of aging. It is a reduction in brain function.

    Several studies have linked higher omega-3 intake to a lower risk of age-related mental decline and Alzheimer’s disease.

    Omega-3 supplements might be advantageous during the outset of Alzheimer’s disease, when the symptoms are modest, according to a review of controlled studies.

    However, always keep in mind that additional research on brain health and omega-3s is required.

  4. Inflammation Is Reduced

    Our bodies’ naturalistic response to infections is inflammation. It protects our organs from damage.

    Inflammation which occurs without the presence of an infection could be dangerous to your health.

    Omega-3 fatty acids might aid in the reduction of cytokines, which lead to inflammation in our bodies.

    People having rheumatoid arthritis who included fish oil in their diet saw good improvement from inflammation, according to studies.

    Omega-3 fatty acids are quite abundant in fish oil.

  5. Help You Lose Fat In Your Liver

    Fatty liver disease is quite more common than you might realize.

    It has become one of the most common causes of chronic liver disease in the world as a result of obesity, as shown in studies.

    Supplementing with omega-3 fatty acids might effectively lower inflammation and liver fat in persons who are suffering from NAFLD.

  6. Menstrual Pain Might Be Reduced

    Menstrual discomfort starts in the pelvis and lower abdomen.

    It then spreads to the thighs and lowers back. It has the potential to have a substantial impact on your quality of life.

    Women who take a lot of omega-3 fatty acids experience milder menstruation pain, according to studies.

    An omega-3 supplement was found to be more helpful than ibuprofen in alleviating severe discomfort during menstruation in one study.

Risks Of Omega 3 Acids

Here are some of the risks associated with omega 3 acids:

  1. Low Blood Pressure

    The ability of omega 3 in decreasing blood pressure has been widely proven.

    A study of 85 dialysis patients found that consuming 2 grams of omega-3 fatty acids per day reduced both diastolic and systolic blood pressure considerably when compared to a placebo.

    Similarly, a review of 30 research found that omega-3 could successfully lower blood pressure, particularly in people who had high cholesterol levels or high blood pressure.

    While these effects could be advantageous to people having high blood pressure, they might be dangerous to people having low blood pressure.

  2. High Blood Sugar

    According to certain studies, supplementing with high doses of omega-3 fatty acids might raise blood sugar levels in diabetics.

    Over ten weeks, one study found that ingesting 10 grams of omega-3 fatty acids per day resulted in a 26% increase in blood sugar levels in patients having type 2 diabetes.

    This is because excessive doses of omega-3s could increase glucose synthesis, which might lead to high blood sugar levels in the long term.

    Different research has produced mixed results, implying that only extremely high doses affect blood sugar levels.

  3. Acid Reflux

    Though omega-3 is quite popular for its benefits related to heart health, many individuals often report experiencing chest burn after they start to use omega-3 supplements.

    Due to its high-fat content, symptoms of acid reflux, such as stomach discomfort, burp, and nausea are common effects of omega-3.

    Several studies have found that fat could cause dyspepsia.

    Adhering to taking supplements after meals and consuming a fair amount might help in reducing acid reflux and ease symptoms.

    You could split your medicines into several parts throughout the day. That might help you in avoiding indigestion.

    At the same time, if one thinks that they might face issues of acid reflux, then they could also add foods for acid reflux that may help them keep the acid reflux at bay.

  4. Gaining Weight

    To burn the fat which has been stored, many people begin to consume excessive amounts of fatty acids.

    Therefore, overeating could quickly lead to weight gain.

    As these fatty acids include substantial levels of calories and fat, they might cause weight gain when consumed in excessive quantities.

  5. Insomnia

    Omega-3 in moderate amounts has been found in certain trials to improve sleep quality.

    For example, research on 385 children found that ingesting 500 mg of omega-3 fatty acids every day for 15 weeks improved sleep quality.

    However, taking too much omega-3 might disrupt sleep and contribute to insomnia in certain people.

    Current research is restricted to anecdotal reports and case studies.

    A high dose of omega-3 was found to increase symptoms of anxiety and insomnia in a patient having a history of depression in one case study.

  6. Stroke

    Hemorrhagic stroke is a type of stroke which involves brain hemorrhage. It occurs due to the rupture of compromised blood vessels.

    According to animal research, a high intake of omega-3 fatty acids might raise the risk of hemorrhagic stroke and reduce blood clotting.

    These findings are also in line with earlier studies which suggest omega-3 might help in preventing blood clots.

    Different research has shown conflicting results with some claiming that there is no link between the risk of hemorrhagic stroke and omega 3 consumption.

Consumption Of Omega 3 Acids

Most health organizations recommend a daily diet of 300-600 mg of combined DHA and EPA, which are the two important types of omega-3 fatty acids.

However, according to research, those with health issues, such as excessive triglyceride levels or heart disease, are generally advised to take a higher dose.

For comparison, a 1500 mg softgel containing fish oil usually contains 500 mg of combined DHA and EPA, but a tsp of liquid fish oil contains 1200 mg.

Omega-3 fatty acid supplements could be safely ingested at levels up to 4000 mg per day, according to the European Food Safety Authority.

If you notice any unfavorable side effects, simply reduce your dosage or try reaching your omega-3 fatty acid requirements through food sources instead.
