Never mind the Mediterranean diet - eating like a Viking can nearly halve the risk of a life-threatening cardiac event, scientists say.
Women regularly eating fish, cabbage, rye bread, oatmeal and root vegetables such as carrots were 45 per cent less likely to have a heart attack.
The same diet in men reduced the risks by almost a quarter, according to a major study in the European Journal of Clinical Nutrition.
The investigation, by a team at Copenhagen University in Denmark, suggests a Nordic diet is every bit as good at protecting against heart disease as foods eaten in Mediterranean countries such as Spain, Italy and Greece.
It backs up earlier research showing that Scandinavian diets can help to lower blood pressure. Other investigations have found they also protect against type 2 diabetes.
To reduce heart attacks, experts have spent years encouraging us to switch to Mediterranean-style dietary regimes which are rich in fish, fresh fruit and vegetables, nuts and olive oil.
