There's also, I fear, a trap here where we believe we understand nutrition, only to discover there are nuances that we still don't have a great handle on.

As an example, there's the emerging posibility that one's gut flora can have a huge impact on overall health - and that certain types of foods can have a negative or positive impact on that gut flora.

Manipulating basic elements could easily lead to our skipping over critical parts of our health needs, with unintended consequences down the line.

Put another way: our dietary habits and nutritional systems developed over tens-to-hundreds of thousands of years. I'm very leery of any theory that we can easily replace that.

Right, gladly I believe we are some way beyond 'emerging' and into 'researching' , 'This year, the US National Institute of Mental Health spent more than US$1 million on a new research programme aimed at the microbiome–brain connection.' http://www.nature.com/news/gut-brain-link-grabs-neuroscienti...
