The Marmot’s at it again. Epidemiogical rubbish, of course. International comparisons are very dicey. There could be many differences in different national populations other than their diets. Just let one fact sink in: Southern Europeans have a much more vegetarian diet than Australians do yet Australians live longer! If the Marmot reads this (unlikely) he would no doubt want to say: “Yes. But there are many other differences …”. To which I would say: “Precisely”
For years the advice has been clear: eating five portions a day of fruit and vegetables is the key to a healthy life. But five may no longer be enough.
A study has found that to get maximum defence against heart disease, you need to eat at least eight daily servings of fresh food.
The Governmentâ€™s five-a-day advice has its roots in World Health Organisation guidelines to include 14oz of vegetables in a daily diet. But there have been doubts over whether eating more than this level of fruit and veg meant even greater health benefits. Now the new study suggests every extra portion provides added protection.
Significantly, those in the Âhighest category â€“ eating eight or more a day â€“ have a 22 per cent lower chance of dying from heart disease than those who consume three Âportions, the UK average. A â€˜portionâ€™ weighs just under 3oz, equal to a small banana, a medium apple or a small carrot.
The findings come from an ongoing European investigation into diet and health, looking at 300,000 people in eight countries. Dr Francesca Crowe, of Oxford University, is working on the project. She said that although ischaemic heart disease (IHD) â€“ the most common form â€“ was less likely in those who ate lots of vegetables, it could be explained because these people might also have healthier lifestyles.
However, the study specifically showed a reduced risk of dying from IHD of around four per cent for each additional portion of fruit and veg consumed above the lowest category, which was those who ate two or fewer portions.
The average intake of fruit and vegetables across all the countries in the study was five portions. People in Greece, Italy and Spain ate more and those in Sweden less.
Professor Sir Michael Marmot, of the University College London, said the findings were of â€˜huge practical importanceâ€™. He said: â€˜Cardiovascular disease is the most common cause of death. A reduction of 22 per cent is huge. There would need to be big shift in dietary patterns to achieve this healthy consumption of eight portions a day. It is worth trying to move in that direction.â€™
Scientists have previously suggested 15,000 lives a year could be saved if everyone ate five a day.
