Brain dysnutrition

We are facing a brain dysnutrition. 


Lack of foods from sea and lakes means a high W6/W3 ratio and even a higher W6/LCW3PUFA ratio, this is not appropriate for newborns and children brain (https://www.youtube.com/watch?v=JmEwAf1aEcQ&feature=youtu.be). 
Secondly a high consumption of high GI carbs which are clearly deleterious for the brain (https://link.springer.com/article/10.1007%2Fs00394-016-1229-6). This lead to hyperactivity in children and depression in adults (https://www.ncbi.nlm.nih.gov/pubmed/28662133). 
Third, the non-evidence based low-fat diet.
It is not clearly proven but the low-fat diet is not good for neurons and especially for stroke nor neurodegenerative diseases. 
Fourth, some other choices do more harm, like veganism, transfats and poor content in micronutrients for those who consume mainly processed foods (https://www.sciencedirect.com/science/article/pii/S0889159118300023?via%3Dihub).
