Capital Radio DJ Margherita Taylor and Sarah Greene, the former Blue Peter presenter, visited the Kids Cookery School in Acton, west London.
The school, which has charitable status, has been awarded a grant worth £2,800 over the next two years by Capital Radio's Help a London Child.
It teaches children from the age of three upwards how to cook and prepare healthy meals, and encourages them to think about their diets.
"The work that the Kids Cookery School is doing is vital at a time when more and more of the food we eat is packaged and processed and so many parents are worried about childhood obesity," said Taylor.
"You should see the pride on the kids' faces when they leave carrying a dish they have created from scratch."
The cookery school is one of 435 London projects sharing £850,000 from Help a London Child.
- Carol Smillie, the television presenter, is the face of Clic Sargent's Yummy Mummy Week, which takes place from 16 to 24 September. Families are being encouraged to organise sponsored toddles, strolls or power walks, but they must do them in their pyjamas. There will also be six pyjama parades around the country. The aim is to raise £400,000 - enough to fund 17 family support workers for a year. "It's about being together and enjoying yourselves out in the fresh air," said Smillie.

It will take place in London on 23 September and in Cannock Chase Forest on 14 October. "Getting fit and helping the environment - what could be more important?" said sports presenter Logan. "I'm delighted to be involved and can't wait to see another 20,000 trees planted."
