Yoani wrote a few years ago on her Generation Y blog about a study showing that the Cubans in the 90s got healthier when the Soviet Union collapsed and they had to eat more vegetables. Here's Yoani's post:
Yoani tells a different story. A story of suicide and starvation and don't ask where this came from. Apparently the Guardian didn't get the story either:
Economic crisis boost to health of Cubans
Maybe the Canadian person that came up with this thesis:
Organic status and dietary role of organoponicos
in Cienfuegos, Cuba
And that English reporter for the Guardian need to go live under those conditions for a while. Then they can tell us how great it is.
