would rather "smoke crack" than eat junk foods.
The 38-year-old actress is an ardent supporter of healthy eating and has previously adhered to a string of unusual diets
- including an extremely strict macrobiotic eating plan - and revealed during a cooking demonstration in London she doesn't eat anything tinned.
She said: "Seriously, I'd rather smoke crack than eat cheese from a can."
The actress and budding chef - who recently unveiled her first cook book 'My Father's Daughter...' - unsurprisingly isn't a fan of fast
food chain McDonald's either, and wouldn't want to take her children there, although she admitted that if they found out children's Happy Meals came with toys it could be difficult.
Gwyneth - who has two children, daughter Apple, seven, and son Moses, five, with her husband, Coldplay
singer Chris Martin
- added: "I take them to Pizza Express because I think that's much healthier. Don't tell them there are toys!"
