DHA, an Omega-3 Fatty Acid, Is Again Linked to Alzheimers Disease

Dead whole fish aren't very appealing to many folks

Linked in a good way.

It’s a little complicated.

DHA is an essential fatty acid. Our bodies need DHA, and certain fish are a good sources for us.

A recent small study found that people with higher levels of bloodstream DHA have less accumulation of amyloid in their brains. Amyloid deposition is a marker of Alzheimers disease. As the dementia starts and progresses, amyloid builds up in the brain. We don’t know if the amyloid is actually causing harm to brain tissue, or is simply a bystander to┬ásome other primary disease process. Some researchers think that if we can prevent amyloid build-up, we can prevent Alzheimers.

A recent MedPageToday article reviews the new study I mentioned above:

“So what’s a clinician to do? Quinn asked. “Maybe the best advice is to adhere to the recommendations from the Centers for Disease Control and Prevention and from the American Heart Association and American Stroke Association, each of which recommend eating fish two to three times per week, primarily for vascular health,” he suggested.

I’ve been recommending at least that level of consumption since 2007. Follow my Advanced Mediterranean Diet or Ketogenic Mediterranean Diet and you’ll get plenty of DHA.

PS: Fish with decent levels of DHA and other omega-3 fatty acids include salmon, trout, mackerel, sardines, herring, and albacore tuna.
