High nutritional standards in schools is an issue that has to remain "high on the public agenda".
Steve Quinn, managing director at Cucina.co.uk, noted parents and educators need to work together to ensure youngsters get access to good quality produce.
Mr Quinn went on to note there has to be a "commitment to the highest standards of nutrition" from everyone involved in education, or else childhood obesity will continue to be a problem in the UK.
He added the government's Nutritional Standards for School Lunches and other School Food sets out what is expected of learning centres when providing food for kids.
However, any academies that have been introduced since 2010 are not bound by law to adhere to the guidelines, which clouds the issue slightly.
An independent study carried out by the School Food Trust discovered meals in these education establishments are not meeting the nationwide benchmark.
One-in-six were found to sell confectionary, while one-in-four offer children the opportunity to buy crisps and savoury snacks.
