HEALTHY SCHOOL MEALS
Children at Southdown Infants School in Bath enjoy tasty homemade
meals such as roast turkey with fresh vegetables, chicken, salad and fresh fruit for
pudding. Vegetables are local, fresh and organic. Instead of crisps,
chocolate and sweets, the school canteen serves organic carrots, dried fruit and
fresh seasonal fruit in bags for 10p, and about 100 bags are sold each day.
Southdown's healthy eating initiative began four years ago with the start of
a breakfast club.
Now Ms Culley, the head teacher of the school, says that the teachers very
clearly see the link between diet and concentration. "Children's concentration and
behaviour definitely improve after a good meal. The teachers would also like to give the
children the experience of eating together. It turned out that some children weren't
used to that.
Pupils are also encouraged to find out more about where their food comes
from by visiting a local farm. Parents are also involved and arc invited
in to try school dinners on special occasions, such as Easter and Christmas .
The efforts of staff, pupils and parents to create a healthy eating environment
were recognized earlier this month when the school was awarded the Best
School Dinner award.
Ms Culley said: "We are happy to win this award. Healthy eating is at the centre of
everything we do. It's really rewarding to see so many children enjoy real food."
