10 Best Findings about Omega-3

Omega-3 fatty acids have many health benefits. And for many people, they do. They’re found in fatty, cold water fish (salmon, mackerel, lake trout, herring, sardines and albacore tuna), canola, soybean, flaxseed and walnut oils, as well as dark green leafy vegetables like kale and collard green. You can also get omega-3 from fish-oil capsules. The following are some findings about Omega-3 for your reference.

1. Omega-3 may help to have late-stage AMD

The Australian study involved over 2900 people aged 49 or older. This study found that “Participants who reported eating at least one weekly serving of fish were 40 percent less likely to develop early-stage AMD (age-related macular degeneration) during the study, compared with those who reported eating fish less than once a month or not at all. People who ate fish frequently were also less likely to have late-stage AMD, the study shows. But that pattern was only seen in participants who reported eating fish at least three times weekly.”

2. Omega-3 may reduce allergy problems of eczema and asthma on the baby.

New research shows that pregnant women who take omega-3 supplements during their pregnancy, as well as during their child’s infancy and nursing, have children with far fewer allergy problems of eczema and asthma. The study had examined infants of expectant mothers from families with high risk of allergy and asthma who were given a fish oil supplement from the 25th week of pregnancy until the third month of breastfeeding. At one year old, the children whose mothers took the supplement had “considerably fewer allergic reactions“. Significantly, they had less than half as many reactions to eggs, which is an early indicator of eczema and asthma. One of the researchers in the study commented that fish oil worked by relieving inflammation in the mother, and this had an effect on the child’s immune system also.

3. Omega-3 may improve the SLE symptoms

A recent study presented at the American College of Rhemutaology found significant improvements in symptoms System Lupus Erythematosus (SLE):“This is the first study in lupus patients measuring improvements in blood vessel function,” said presenter and investigator Stephen Wright, MD, “After 6 months we saw evidence confirming the beneficial effects of omega-3 fish oils for improving symptoms of lupus and, also, evidence of a cardioprotective effect in these patients,”. After 6 months of fish oil supplements, there was a statistically-significant improvement in lupus symptoms.

4. Omega-3 may reduce hyperactivity, inattention and impulsiveness in children.

Omega-3 is vital for fetal brain development and now its thought a deficiency in the womb can lead to blood pressure problems in adulthood. Doctors also believe that if kids don get enough omega-3, they may develop learning, psychiatric and behavioural problems later on. A study by Dr Natalie Sinn at the University of South Australia found the fish oil supplements reduced hyperactivity, inattention and impulsiveness in half the children taking it. It also helped children who suffered from ADHD symptoms. So get more omega-3 to kids by giving them fish in foods they enjoy, like a seafood pizza.

5. Omega-3 may enhance infant development

A new study funded by Health Canada and other organizations has proven a direct correlation between dietary consumption of the omega-3 DHA and enhanced infant development. The study, which was supervised by Universite Laval researchers and published in the Journal of Pediatrics, reveals, DHA consumed during the last months of pregnancy boosts an infant's sensory, cognitive, and motor development. The research team reached its conclusion by first measuring the amount of DHA concentration in the umbilical cord blood of 109 infants. "DHA concentration in the umbilical cord is a good indicator of intra-uterine exposure to omega-3s during the last trimester of pregnancy, a crucial period for the development of retinal photoreceptors and neurons," said study supervisor Dr. Eric Dewailly. After testing the infants at six and 11 months, the researchers discovered visual acuity, cognitive development, and motor development were closely linked to DHA concentration in the umbilical cord blood at the time of their birth.

6. Omega-3 may boost the brain-power

Expectant mothers who eat enough omega-3 fats late in pregnancy may give their babies a brain-power boost, a new study suggests. Researchers found that among 109 Inuit infants they followed, those whose umbilical-cord blood was higher in docosahexaenoic acid, an omega-3 acid, at birth did better in tests of infant brain and eye development at the ages of 6 and 11 months.

7. Omega-3 may help reduce the risk of recurrent miscarriages

One of the common causes of recurrent miscarriages is a condition known as antiphospholipid syndrome (APS). Early research suggests that fish oil, which contains omega-3 fatty acids, may help reduce the risk of recurrent miscarriages in women with this condition. This may be due to the "blood-thinning" properties of omega-3 fatty acids, since antiphospholipid syndrome can cause miscarriages by causing blood clots, or to other properties of fish oil.

8. Omega-3 , do consult your doctor for any subscription.

If you are pregnant, it is always a good idea to have a discussion with your healthcare provider before taking any medication or supplement, including omega-3 fatty acid products. It is important that you chose an omega-3 supplement that is free of toxins. Be sure to not exceed your healthcare provider's recommended dose of omega-3 fatty acids, since high doses can increase the risk of bleeding.

9. Omega-3 could be fatal

The pioneering research of Alexander Leaf, MD, at Harvard Medical School has found that in some cases omega-3s could be fatal. One of the reasons omega-3s may decrease the incidence of sudden cardiac death is that they stop those cardiac cells that are the most unstable from functioning. But in people who have angina (chest pain or tightness due to heart disease) or congestive heart failure because their hearts are not receiving enough blood flow, removing those cells from functioning can reduce the heart’s ability to pump blood so much that it may increase the risk of sudden cardiac death.

10. Omega-3 should be avoided for certain cases.

Avoid omega-3s if you have recurrent angina, congestive heart failure or evidence that your heart isn’t receiving enough blood flow when you exercise.

Not all are true. Everyone has their own way of thinking but I think they have to reconsider. I like to argue for the most accurate results.

I know there will be many difficulties and challenges but I am determined to do it. If it does not succeed then it will be a lesson for me as well
