不少人提倡多吃水果和蔬菜。事实证明,吃果蔬确实有助于改善健康。专家建议每天应吃 “five-a-day(五份水果和蔬菜)”。但在日常生活中,坚持这种饮食方式容易吗?我们是否应设定一个更现实的饮食目标来保持健康?本期节目探讨英文谚语 “An apple a day keeps the doctor away. (每天一苹果,医生远离我。)” 背后的科学依据。

We all know about the benefits of a healthy diet. 'We are what we eat', so some say. But sometimes our busy lives mean our healthy intentions slip, and we end up eating the wrong things. Messaging telling us to eat our 'five-a-day' encourages us to maintain a balanced diet – but is it accurate?

If you're not sure what your 'five-a-day' is, it's a campaign based on advice from the World Health Organization which recommends eating a minimum of 400g of fruit and vegetables a day. That should lower the risk of serious health problems, such as heart disease, stroke and some types of cancer. Variety is important because different fruits and vegetables contain different combinations of fibre, vitamins, minerals and other nutrients.

Eating five pieces of fruit and veg is something to aim for. An analysis of 16 worldwide studies suggested that for every portion of fruit and vegetables consumed, there was a lower risk of premature death. And in the UK, previous research by the University of Oxford found around 33,000 lives a year could be saved if everyone in the UK followed dietary guidelines. Dr Peter Scarborough told the BBC: "According to our model, the biggest impact would be eating more fruit and veg. But this doesn't mean you should just stop at five – the more the better."

However, there are some doubts about the 'five-a-day' message. Some fruits and vegetables are better than others. And counting orange juice, for example, as one of your portions isn't so beneficial because it contains sugar. Also, eating more vegetables than fruit tends to be better because they're richer in nutrients. Some doctors also say the message is too ambitious, and a 'two-a-day' message might be a more realistic starting point.

There have been calls to up the quota to seven-a-day, but research reported in The British Medical Journal found after five portions a day, there was no further impact. But whatever fruit and vegetables you consume, every piece can help reduce the risk of cardiovascular disease and cancer. As the old saying goes: 'an apple a day keeps the doctor away'.
