Mr Oliver, who owns the new "Fifteen" restaurant in London, has urged people with problems learning English and maths to enrol on the free courses being offered by the Government.
"To be honest, when I was young I was more likely to be poring over a chopping board than a novel, and it's just the same with the trainees I've taken on at 'Fifteen.'
"But just as I pulled my own socks up and sorted out my difficulties with reading and writing, I try to encourage them to really focus on improving their skills.
"It's never too late to go back to the books and hone your academic side - whether you are 15 or 55, or even 85.
"It will make you more confident and capable of improving your job prospects, whether you want to be a chef, a carpenter, a DJ, or Bob the Builder.
"The secret of cooking genius food might not change, but your reading, writing and maths skills can."
The Government's adult basic skills campaign "Get On" provides free courses around the country. It aims to raise skill levels in 1.5 million adults by 2004.

One in eight people admits that a lack of confidence about writing is the biggest single factor in not sending cards during the festive period.
