US guidelines are that no more than 10% of your calories should come from from sugar.
Study found no ill effects in people who ate 20 servings of fruit a day for 12 to 24 weeks.
Sugar content of fruit is released slowly into the bloodstream because it is packaged inside cells which digestive enzymes have to break down.
Also, whole fruits are full of antioxidants and other nutrients as well as being high in fibre.
You should limit sugar from processed foods – including fruit juice where cells have already been broken open by the process of squeezing.
