Stop Wasting Money

The problem is that thus far all of the clinical trials have either included too few patients or were conducted for quite brief periods of time. Read More

Other effects

Taking it for dementia prevention may not be effective, but don't omega 3's have benefits for heart health and inflammation? You might be advising people to throw the baby out with the bath water.

benefits for the heart

This person makes a great point, however, the study was conducted solely on patients with cardiovascular problems primarily for this reason. The authors have not yet published their results on the general health effects.

cow pig - really?

Hi, Gary. Thanks again for your work here - it is very helpful and always interesting!

Can you explain your comment about avoiding cow/pig? Is that just a throw away line or are you serious and if serious, what about high quality meat (grass fed for beef, grazing for pigs, etc)?

thanks for clarifying!

Cows and pigs

Yes, I was quite serious about that advice to avoid virtually everything from a cow or pig.
On August 17th last year I wrote a blog on this site entitled, For your brain's health stop doing these things. I summarized a series of recent studies (the specific references are listed at the end of the blog) that make this point. Currently, it is not possible to defend eating meat or dairy products from grass fed or hormone free cows. With regard to the studies I quoted, these issues, while important concerns, are not relevant to the risks related to eating red meats.

Omega-3 intake and brain health

Dear Professor Wenk,

Here is a study from our lab suggesting that a high intake of omega-3 fatty acids is linked to brain health in elderly.

However, I admit that it cannot be ruled out that the positive association between the dietary intake of EPA and DHA and brain health observed in our elderly study population is driven by the adherence to an healthy lifestyle, rather than by these nutritional factors alone. Further, it must be born in mind that the beneficial effects are relatively small, as compared to those related to other lifestyle factors, such as regular exercise.

Best,
Christian

Omega 3

Why not just eat fish and sea food. I guess that would be better than buying capsuled omega 3. Regarding not eating meat from cows and pigs, it say there "Avoid almost anything from a cow or pig". "Almost", so thats not really inhibiting from this kind of meat. Besides, minimizing intake of red meat is beneficial also.
