Not denying the anti-inflammatory effects of omega 3.
However, do we know that whether the anti-inflammatory effects of omega 3 can be replaced by the anti inflammatory effect of other compounds ? For example, cucurmin is well known to be anti inflammatory. Do you think I can cut down on omega 3 if I increase my tumeric intake (and vice versa) ? As comparison, for simplicity sake, different dietary antioxidants exert anti oxidant effects on different things and can generally not be replaced like for like. Vitamin C cannot replace vitamin E (over simplified for argument sake)
Please note that i am specifically refering to the anti inflammatory effects of omega 3 and I am not talking about other functions of omega 3 (e.g. DHA for cognitive effects)
Short answer is no, because they have different mechanisms for achieving their effects. When different chemistry is happening, the results will never be identical. We don’t have the tools to graph exactly what happens at the cellular level system-wide when ingesting specific compounds. We can look at blood markers, petri dishes, perform experiments, etc. But different compounds behave differently in the cosmos that is the human body
