Cartoon characters to curb obesity

The site, launched this month, introduces children to a new world of fruit and vegetables they may not have tried before and encourages them to cook with them and even to grow them.

A spokesman for the World Cancer Research fund warned that eating poorly now could cause health problems in later life.

"Many cancers take years to develop - so it's important that children, and those who care for them, and young adults hear our message.

"Poor lifestyle habits are established in childhood, and these may contribute to our children's risk of cancer later in life."

Poor diet and lack of activity indirectly contribute to cancer risk through overweight and obesity, he explained.

"But we also know that a diet rich in plant-based foods, fruit and vegetables, can reduce cancer risk, as can being more physically active."
