Sugar issues
Speaking to BBC Radio 4's Today programme Mr Coupe said the company was taking action to cut down on sugar in its products and to cut waste.
The firm said it had removed close to 35 tonnes of sugar from its own-brand juices and juice drinks, and continued "to reformulate our products to improve quality and taste and to reduce sugar".
He said there had to be a "holistic approach" from society to cutting childhood obesity, including more information about calories generally, and looking at ways to burn off calories.
On waste, he said the firm was looking to provide the quality in products - such as fruit and vegetables - that customers demanded, including with regards to shape, texture, and "visual cues".
The firm, he said, donated unsold food to charities, or sent it for conversion into animal feed.
