The secret of a long life could be to eat sushi and drink green tea.

Japanese women live longer than those anywhere else in the world, figures show — and experts say their diet plays a key role in their longevity.

What’s more, they say, there is no reason why the ladies of Britain can’t catch up — if they are willing to change their tastes.

Craig Willcox, an expert who has studied the effects of diet on health and ageing in Japan, said the food that is eaten is simple.

He told the Times: “They eat three servings of fish a week on average, plenty of whole grains, vegetables and soya products too, more tofu and more konbu seaweed than anyone else in the world.”

Konbu seaweed has been described as a “nutritional powerhouse” that is rich in vitamins, iron and other minerals.

Sushi, a favourite food of tennis star Andy Murray, is high in appetite-quenching protein.

Green tea, meanwhile, is especially high in chemicals that are thought to cut cholesterol and protect DNA from damage.

The calorie intake in Japan is 25 per cent lower than in the average Westerner.

The latest data from the Office for National Statistics gives Japanese women a life expectancy of 86.4 years. This is almost four years longer than the 82.6 years forecast for their British counterparts.
