A、Adding as many colors as possible in the fruit. B、Cutting the fruit into different shapes. C、Making the fruit into a hedgehog.

Making fruit look good holds the key to getting children to eat more of it, a study suggests. In tests, when offered the same amount and types of fruit, children ate far more if it was made fun and attractive, the journal Appetite reports. The researchers, who studied nearly 100 pupils in the Netherlands and Belgium, say parents and schools should follow this example. However, they said food presentations needed to remain innovative. In the study of children aged four to seven, apples, strawberries and seedless grapes were put on offer, but presented in different ways.
    Given the choice, the children plumped for these fruits more readily when they were made into a hedgehog — skewered with colorful cocktail sticks that were pierced into a watermelon. The same cubed fruits did little for the children’s palates when they were simply offered on a white dish. Children ate nearly twice as much of the "fun" fruit, even though they said they understood that both fruit options — hedgehog and plain dish — should taste the same.
    The researchers suggest supermarkets could also capitalize on the findings to make fruit more appealing for children and their parents alike. But[27]they also warn that "fun" fruit presentations might soon lose their appeal with children if they were used too many times. It is probably necessary for parents and food producers to remain innovative.[28]And for parents who do not have the time to make elaborate fruit faces and flowers from carrots and radishes, there are simpler ways to make foods interesting, such as cutting it into triangles, squares or strips.
