The press release had a curious title: “Omega-3 fatty acids protect against Parkinson’s.” The certainty suggested an experiment, but Parkinson’s is too rare to study prevention experimentally. The press release turned out to be about a rat study that used a drug called MDPT to cause brain damage that resembles Parkinson’s. Rats given a high-omega-3 diet suffered much less damage — apparently none — from the drug.
Rats given the high omega-3 diet had much less omega-6 in their brains than control rats — one more reason, in addition to the Israeli Paradox, to think that omega-6 may be just as bad as omega-3 is good. Omega-3 may act by displacing omega-6 (they are almost identical physically).
The results could have been taken to suggest both (a) eat more omega-3-rich foods, such as fish and (b) eat less omega-6-rich foods, such as vegetable oils, but only the first recommendation reached the public.
You might as well just stick our mission statement here. Reaching the public directly is our whole reason to exist. Newspapers have to sell the sizzle and not the steak whereas we have you to give us the real deal. Looking at the "related articles" box above, it is chock full of Omega-3 articles, some good, some bad (most look like news releases though) but we carry everything that comes out.
