But - as Christopher Fountain reports - I'm not so sure........
A six-year-old boy who went to school with a bag of Mini Cheddars in his packed lunch has been suspended for four days after teachers said it contravened its healthy eating policy.
Riley Pearson, from Colnbrook, near Slough, was excluded from Colnbrook C of E Primary School after teachers discovered the snack and called in his parents.
After a meeting with headmaster Jeremy Meek, they were sent a letter telling them Riley would be excluded from Wednesday until Monday because he had been 'continuously breaking school rules'.
The school, which was placed in special measures after Ofsted inspectors deemed it 'inadequate' in 2012, introduced a healthy eating policy at the start of term.
A letter was sent to parents saying that from 14 January, packed lunches should be 'healthy and balanced'.
Parents were told: 'Chocolate, sweets, crisps and fizzy drinks are not allowed.
Well. There you have it!
