A school has marked parents down - after some packed "extreme" or "worrying" lunches for their loved ones.

A newsletter sent to parents whose children are at Byron Primary School in Gillingham highlighted several examples of poor packed lunches.

They included:

• A cold McDonald's happy meal bought the previous evening
• two bags of crisps and a crisp sandwich
• four yogurts and a packet of smarties
• and one chocolate muffin, one chocolate roll and a bar of chocolate.

The sinful treats were highlighted in the newsletter sent out by headteacher Jon Carthy.

He wrote: “Whilst extreme and funny to read on paper, I must make this clear THESE ARE NOT ACCEPTABLE examples of a balanced packed lunch.

“Children work very hard at school and a balanced meal at lunch time helps provide concentration for the afternoon.”

He reminded parents of government guidelines for packed lunches which includes one portion of fruit and vegetable/salad every day, meat, fish or a source of non-dairy protein, oily fish and starchy foods such as bread or pasta.

Mr Carthy added: “If we feel as though any child is not getting a regularly balanced meal, we will contact you and offer you advice.”

What do you think? Should children get a treat in their packed lunch - or do they need a healthy diet while at school? Join the debate below.
