Live-longer secrets from women around the world

Iceland: put fish on the menu

Harsh weather, a rugged terrain and long seasons of darkness hardly sound like a formula for healthy living, but Icelanders are among the fittest people on the planet and among the longest lived of any nation in the western world. The secret to their wellbeing? The amount of fish in their diet. The health-giving properties of oily fish are well known - the Omega 3 oils it contains have been shown to protect against stroke and heart disease, as well as fight joint disease and signs of ageing, and may even help protect against Alzheimer's.

Action point Eat salmon once a week. At the moment, the average intake of oily fish in this country is around a third of a portion a week and 70% of us eat none at all. The Department of Health says everyone should eat a minimum of two portions of fish a week, and at least one of these should be an oily fish, such as salmon, mackerel, trout or herring.
