I believe it’s too risky to eat fish anymore due to heavy metals and the pollution in the ocean. I think we should let the fish repopulate and hopefully heal from efforts we can make to clean up the oceans. In the meantime what do we eat instead of fish to help us stay healthy? Lots of people have asked this question. A lot of us eat plant based now. I love fish but don’t trust ratting it now if only occasionally.

What is it about fish? Since our oceans are becoming over-fished and there are many metals and other toxins in much of our fish stock, aren’t we better off taking omega oils made from algae, which is how those fish get the healthy tissue for us to eat in the first place?

Harold, your diet and your sense of humor are a great combo for longevity .. as are genes, environment and luck.

Yes, we should all eat bountiful quantities of fish. Where are all these fish to come from? We inhabit a planet where excess extraction and severe environmental blight are currently crushing life in the oceans. 96% of bluefin tuna are gone! We are to blame. So the answer lies not with extracting and consuming more fish, but in a massive change in international fishery laws, environmental regulations, (plastic, especially, and coal burning, which spews mercury), and sharp attention to the climate crisis (coral reefs are massively dying). Let’s get to work.

I think one important aspect you missed is daily exercise
That is exercising to a point where your breathing is laboured
I feel this is the most important thing one can do for sharp brain function

The sad thing is that exercise is not a guarantee to not get the disease. I had a friend who was an avid runner and got early onset Alzheimer’s at 57. His heart was in amazing health as was his body. You can do your best but it does not always work. I feel stress is a huge contributor to getting this disease.

In general, fish is far more expensive in Canadian groceries than meat. It makes eating fish an expensive habit. That said, I would like to know how frozen fish (which is all we can get) compares to fresh fish on the east coast (plentiful for those who live along the coast).

I’ve also read a study that Vitamin D is important for lowering the chances of dementia. That would make sense since it’s in fatty fish, and some of the other foods mentioned here. Your mother sounds like a smart women. Mine always used to tell us we should eat fish twice a week.

“Fish is Brain Food” – I grew up in New Zealand!

My motto has always been: “Eat everything, some of it will be good for you.” I’m 90; so far, so good.

May 11, 2020

Yep. This surely aligns with traditional wisdom. I grew up hearing from multiple generations of ancestors that “Fish is brain food!”

If one is allergic to ALL fish and shellfish, what is the substitute that could offer the same benefits?

This is a great article I can share with my older clients!

“To reduce your risk of cognitive impairment and decline, eat a Mediterranean-style diet” I am not sure that you can interpolate into “Mediterranean -style diet” conclusion from the new study.

Fish rich diet or Seafood rich diet is more appropriate.
