Experts say eating a range of fruit and veg is best, as part of a balanced diet, to protect against illness

Research suggests eating at least seven portions of fruit and vegetables a day is more effective at preventing disease than the government's current five-a-day recommendation.

Is five a day enough?

Yes - but people should eat at least five portions of fruit and vegetables a day, the government says. The advice is based on World Health Organization guidelines, which are 25 years old.

Dieticians say eating five a day is enough to get the protective benefits of fruit and veg - although eating more may be additionally beneficial.

What counts as a portion?

Fruit juice counts towards one portion of the recommended five portions per day

For an adult, a minimum of 400g of fruit and vegshould be eaten every day, or five portions of 80g.

The amount varies for children, based on activity levels and age, but a rough guide is that one portion should fit in the palm of their hand.

Fruit and vegetables do not have to be eaten on their own and can be cooked in dishes such as soups, stews or pasta meals.

Do tinned fruit and fruit juice count?

Yes. But juice should be unsweetened, and only counts as one portion a day, as it contains less fibre than whole fruits and vegetables.

Fruit must be tinned in natural juice, or water, with no added sugar or salt, and not in syrup, which lots of fruit is.
