Fruit and veg: More than five-a-day 'no effect' 하루에 과일과 채소 5인분 이상 먹는다고 별좋은 효과 없음

Some countries recommend eating 10 portions a day of fruit or veg 일부 국가들은 하루치 과일이나 야채의 10인분을 먹으라고 권고한다

New research backs the five-a-day target for fruit and vegetables, but suggests eating more may have no added benefits. 최신 연구에 의하면, 과일과 야채를 하루에 5인분까지 먹는 건 괜찮지만, 그 이상 먹는 것은 몸에 좋을 게 없다. 

An analysis of 16 worldwide studies suggested that for every portion of fruit and vegetables consumed, there was a lower risk of premature death. 전세계 16개 연구를 분석한 결과에 따르면, 일인분의 과일과 야채를 섭취하면 조기사망의 취험을 낮춘다고 한다.  

But after five portions a day, there was no further impact, researchers report in The BMJ. 그러나 하루에 5인분을 먹는다해도, 건강에 도움되는 면은 없다고, 연구자들은 영국의학저널(밝은하늘註: The British Medical Journal)에서 밝혔다.

There have been calls to up the quota to seven-a-day, to prolong lives. 목숨을 연장하기 위해 하루에 7인분까지 한도를 높여야 한다는 요청이 있어왔다.

Current NHS guidance is to eat at least five portions of fruit and vegetables a day. Most people manage about four. 현재 국민의료보험(밝은하늘註: National Health Service)의 지침에 따르면, 하루에 적어도 5인분의 과일과 야채를 먹어야 한다. 대부분의 사람들은 4인분까진 먹는다.

Most people do not eat five portions of fruit and veg a day, so the message for the public is still to eat more fruit and veg”

The new analysis looked at 16 studies in the US, Asia and Europe involving more than 833,000 people, of whom about 56,000 died during the follow-up period. 최신의 분석은 833,000명 이상이 참여한, 그 중에 56,000명이 투병기간에 사망한  미국과 아시아와 유럽에 진행한 16개의 연구를 고찰하였다.

Researchers in the US and China found eating more fruit and vegetables was linked with a lower risk of dying from any cause, particularly from cardiovascular disease.

The average risk of death fell by about 5% for every extra serving of fruit and vegetables, up to five servings a day, but not beyond.

"This analysis provides further evidence that a higher consumption of fruit and vegetables is associated with a lower risk of all-cause mortality, particularly cardiovascular mortality," said the team, led by Prof Frank Hu, of Harvard School of Public Health, in Boston, US.

"There was a threshold around five servings of fruit and vegetables a day, after which the risk of all cause mortality did not reduce further."

Eating even five portions of fruit and vegetables a day is a challenge for many

Seven-a-day?

There have been calls to increase the quota of fruit and vegetables beyond five.

A previous study in England found eating seven or more portions of fruit and vegetables a day was healthier than the minimum five currently recommended and could prolong lives.

But lead researcher Dr Oyinlola Oyebode, of University College London, said both studies showed eating more fruit and veg was associated with lower risk of early death.

"This study suggests not much additional effect over five portions, although there was possibly a greater effect in the groups eating five to seven, and seven plus portions in our study," she told the BBC.

"Most people do not eat five portions of fruit and veg a day, so the message for the public is still to eat more fruit and veg."

Five a day facts

• The five-a-day message is based on advice from the World Health Organization

• It highlights the health benefits of eating five 80g (3oz) portions of fruit and vegetables every day

• The five portions should include a variety of fruit and vegetables

• Most fruits and veg count towards five a day

• The government says it can include fresh, frozen, canned, dried or pure juices

• Potatoes and cassava don't count because they mainly contribute starch to the diet

Commenting on the study, Victoria Taylor, senior dietician at the British Heart Foundation, said: "Although our five-a-day message is well established, worryingly 70% of adults are still not meeting this target.

"Just remember that every extra portion you eat towards your five-a-day could help you keep your heart healthy."

Dr Alison Tedstone, chief nutritionist at Public Health England, said: "The majority of people in England are not eating enough fruit and vegetables with the latest National Diet and Nutrition Survey (NDNS) data from 2008 to 2012 showing that only 30% of adults and 41% of older adults met the five-a-day recommendation.

"Eating a healthy, balanced diet that is high in fruit, vegetables and fibre and low in saturated fat, sugar and salt, alongside being more active, will help you to maintain a healthy weight and lower your risk of developing heart disease, type 2 diabetes and some cancers."
