Fifteen-year-old males who ate fish at least once a week displayed higher cognitive skills at the age of 18 than those who it ate it less frequently, according to a study of nearly 4,000 teenagers published in the March issue of Acta Paediatrica.

I ate fish, baMguDe (mackerel) or bUtAyi (sardine), at least once a week when I was 15. By 18 my intelligence was down by 20% and by 22, by 25%.
In Sweden they have an issue with vitamin D, you know. Fish is the main alternative source for this crucial vitamine, other than the sun. Vit. D is crucial for a correct developement of the brain and its lack has been associated with severe mental problems, including schyzophrenia.
ReplyDeleteI don't believe that your intelligence dropped, much less for eating fish. :-P
We South Indians are other extreme. We have Vitamin D overdose due constant exposure sunlight and fish (unlike northern India). Studies have already found hyper Vitamin D increases heart attack risk. And we also know hypo Vitamin D adversely affects the heart. If we generalize this fact, we can say hyper Vitamin D in fact reduces the cognitive skills just as hypo Vitamin D.
ReplyDeleteThe present study on Swedish has found that fish eating among 15 years old balances Vitamin D in hypo Vitamin D people. A future study on South Indians will find non-fish eating among 15 years old does the other way round.
Please add prepositions wherever it's necessary :-).
ReplyDeleteWell, someone lectured me at my blog on how sun-generated vitamin D in excess is destroyed by the body.
ReplyDeleteReally not sure if fish is bad for the brains or the hearts of tropical peoples but I'd tend to doubt it in principle. After all people have been eating fish since "always" in those areas, and they would not if it was harmful.

ReplyDeleteDoes that mean body always balances Vitamin D? I doubt. Wikipedia article says South Indians with heart disease had elevated levels. How is it possible?
No, ingested vit D is not easily destroyed, only that taken from the Sun, which is at the very skin level.
ReplyDeleteStill I guess one would need to eat oily fish much more than just once a week to have problems. A lot of peoples around the world depend largely on fish for their daily meals and never heard before now that this could be related to any sort of problems.
