Tips on making up a healthy school lunch for your little ones

HERE’S a little maths question to get you into training for the upcoming back-to-school season: if an Irish 14-year-old boy weighed, on average, 37kg in 1948, how much does he weigh today?

Add in an obesity epidemic, subtract daily exercise and multiply your findings by the increasing availability of junk food near, if not in, schools.

The answer? An average 14-year-old boy today weighs 61kgs, some 24kgs (or 3st 10lb in old money) more than his counterpart in 1948.
