They are both important and essential. The balance between omega 6 and omega 3 in biological membrane is regulated by dietary dietary supply. According to Waleed et. al 2017, omega6/omega3 ratio of 5:1 is highly recommended in diets.

Dear Mr. Singh,

supposedly you refer to the study "Aung, T., Halsey, J., Kromhout, D., Gerstein, H. C., Marchioli, R., Tavazzi, L., ... & Chew, E. Y. (2018). Associations of omega-3 fatty acid supplement use with cardiovascular disease risks: meta-analysis of 10 trials involving 77 917 individuals. JAMA cardiology, 3(3), 225-234.", which find no association between the consumption of n3-PUFAs and CVD endpoints.

Analyzing the results of this meta-study we have to bear in mind that the study with the strongest opposite effect was the ORIGIN trial (Bosch J, Gerstein HC, Dagenais GR, et al; ORIGIN Trial Investigators. N-3 fatty acids and cardiovascular outcomes in patients with dysglycemia. N Engl J Med. 2012;367(4):309-318.)

A randomized trial with relatively low levels of EPA and DHA (464mg and 375mg per day) in the control group and - even more importantly – 1000 mg olive oil in the placebo group.

Bosch et al. write: “Participants underwent randomization, after a 10-day run-in period, to receive either 1 g of n–3 fatty acids (containing 465 mg of eicosapentaenoic acid [EPA] and 375 mg of docosahexaenoic acid [DHA]) or placebo containing approximately

1 g of olive oil.”

As also olive oil shows cardioprotective properties the meta-study of Aung might be biased.

As polyunsaturated fatty acids, both the omega-6 and the omega-3 families have more than one double bond in the carbon chain. .

Omega-6 is pro-inflammatory, while omega-3 is neutral. A diet with a lot of omega-6 and not much omega-3 will increase inflammation. A diet of a lot of omega-3 and not much omega-6 will reduce inflammation. Study suggests that our ancestors consumed omega-6 and omega-3 fats in a ratio of roughly 1:1.

Quite possible but no phase III trial

both, omega-6 and omega-3 fats are important to eat. the issue is the type of oils matter got health. so i suggest both, omega-6 and omega-3 fats but the intake should be with recommended amount. eating much omega-6 and omega-3 fats may not keep health and there must be with recommended intake

Both are essential for health but daily recommended intake must be considered from any source you are taking it from.

for healthy diet eating much omega-6 and omega-3 fats may are good

Both are essential, and must be consumed in adequate amounts, but not in excess.

both are useful, but should be considered for the ratio.

correct answer Dr junaida

Source should also be considered. I like recommending flaxseed oil because it contains polyunsaturated fatty acid with a 3 to 1 omega3/omega 6 ratio. Flaxseed oil has more omega 3 than omega 6 and has been found to be effective for reducing triglycerides and hypertension. Perhaps the ratio should have more omega 3 than omega 6 to favor an anti-inflammatory effect. Eating whole fish would give you DHA omega 3 and omega 6 whereas many fish oil capsules only contain omega 3.
