Icelandics have the LOWEST consumption of fruit/ veg in Europe and one

of the highest rates of longevity in the world. I put it down to

fish/seafood (Vitamin D ion skin and liver, selenium, iodine and

phosphorus) and little junk food.

Whatever government says, my rule of thumb...

Rotate the information 180 degrees and there in lies the truth :-)

P.S I like Weston. He's Canadian ;-)

I watched a programme on tv about a year ago about two young twin

British doctors who went round the world to test out different, non-

mainstream or traditional medicines and diets. Did anyone see it? I've

forgotten what it was called.

Anyway, in one episode they were in a remote part of Russia where the

land is frozen and the people eat from the sea. These people live longer

than anyone else on Earth and when they were measured by the doctors,

they had enormous strength and speed, strong hearts and lungs and little

disease. (apart from one bloke who had married a white Russian woman and

was eating cakes and tinned foods, etc) The doctors raced and did all

sorts of competitions with them. They were young and sporty doctors but

lost everything and were easily beaten by much older men and women.

They ate almost entirely from the sea, fish and sea mammals, apart from

some berries which they found under the snow for a very short period of

the year (like a week or two). I don't remember them eating any seaweed

but they may have done. Importantly they ate lots of fermented food.

Found this fairly irrelevant clip of it on Youtube. It was called 'the
