I knew there was a reason I love sushi

I just read an interesting article in the New York Times reporting that older adults in Asia and Latin America are less likely to develop dementia if they regularly consumed fish. What is perhaps even more surprising is that the opposite effect was found for meat- the more you eat it, the more likely you are to develop dementia. Now, before you throw out all your meat and worry about the irreparable damage you've done to your brain, keep in mind that the results should be taken with a grain of salt. All the data was gathered from observational studies, inviting many confounding variables which could just as well account for the results. The New York Times is once again very vague on how the studies were conducted (sadly, it is not an academic journal and not many people want to hear about sample size, research protocol, and statistical tests used). Nonetheless, it's interesting stuff, and I invite anything that encourages my scary obsession with sushi.
