Oily fish advice unsustainable

Whatever the health benefits of eating more fish, this target is incompatible with declining fish stocks ('NICE puts lifestyle at heart of new QOF').

No fish can be regarded as sustainable with rising human populations, climate change and overfishing. Take herring. A quick trawl through the internet yielded figures from Cefas recommending an annual limit of less than 180,000 tonnes or less than 3kg per year per UK person. The total global catch available is only 80 million tonnes for a population of 6.783 billion.

We will have to research the benefits of eating jellyfish.

Luckily nobody pays any attention to our dietary advice, and most folk can't afford fish.
