You may have seen the recent headlines that eating 10 fruit and vegetables a day can prevent a whole host of illnesses and premature deaths as a result of these. But where did this information come from? What are the health benefits? And should we be doubling our intake of fruit and vegetables?
The Origins of 5 A Day
5 a day came about in 2003 when the World Health Organization (WHO) published a report that assessed the findings of many scientific studies on fruit and vegetable intake and their effect on health. The WHO reported that daily consumption of 400-500g of fruits and vegetables is advisable to reduce risk of developing cardiovascular related problems such as high blood pressure, stroke and coronary heart disease. This recommended quantity of 400g was then used to develop the 5 a day campaign by dividing the 400g target into five 80g portions of fruits and vegetables. 80g portions are a realistic quantity and breaking these down across the day to achieve 5 portions is manageable, whilst it also promotes variety as each of the 5 portions should be a different fruit or vegetable to get a range of different micronutrients.
