A chicken shop has been closed down, after health inspectors described it as one of "the filthiest premises" they had seen in a long time.
The London Food Board has launched a website designed to help point people towards local services that can provide food for those in need.
The London Assembly is calling for more action to help thousands of people going hungry in the capital, including school children.
School children have had a chance to hit Borough Market and sell fruit and veg they've grown themselves today.
Emma Walden went to see how they were getting on.
Children from St Mary Magdalene Church of England Primary School are among those selling the fruits - and veg - of their labours at Borough Market today.
Here are some pictures of them planting their seeds earlier in the year.
The schools taking part in today's Harvest Sale at Borough Market are:
St Mary Magdalene Primary School
St Paul’s C of E Primary School
Surrey Square School
Charlotte Sharman Primary School
Charles Dickens Primary School
John Ruskin Primary School
Gloucester Primary School
Goose Green Primary School
Dog Kennel Hill Primary School
Children at primary schools across London have been growing their own fruit and vegetables as part of an initiative run by the charity School Food Matters.
By growing food from seed, it helps teach the children where food comes from - the ground, not the supermarket!
Pupils from several London schools will be trying their hand at market trading today, selling fruit and vegetables they've grown themselves.
They'll be joining stall-holders at Borough Market in south London to trade their pumpkins, squashes and beetroot for hard cash.
All of the proceeds will go to FareShare, a charity that works to relieve food poverty.
