Health researchers now agree that smoothies are quite healthy for you and that they can count as up to two of your five-aday fruit and vegetable quota.

Leading smoothies makers, like Innocent, recently bought in part by Coca Cola, will welcome this claim. Innocent became a pioneer of suggesting that smoothies could count as part of your five-a-day. Yet they found that some customers complained, claiming that smoothies shouldn't be counted as part of the daily fruit and veg quota.

But after research from the Department of Health the claim but Innocent stood up.

Not all smoothies are the same though. Where Innocent fruit smoothies contain two portions of fruit a day, other smoothies sold at Sainsburys, for example, not only doesn't contain enough natural fruit but some also contain a quarter of a woman's daily fat recommendation.
