stainless steel knife

[old-wos-is-name]

Hi all,
I was chopping up a cabbage at lunchtime today and the othe half said not to cut it too finely as the stainless steel blade kills the vitamins and minerals.
Is this right????? sounds rubbish to me.

yes - will react with metal other than stainless steel

[carrot99]

with a stainless steel knife because other metals might discolour you - no?

[ummmm]

I'm reading it the same as carrot....

My social worker doesn't let me have sharp objects.

how about if you cut it thickly with a stainless steel knife?

Irrelevant of the knife type I thought Vit C started to break down when any fruit or veg is broken/chopped, as is a lot lost in cooking.

gingejbee has it right. It's all to do with the surface area, nothing to do with the knife.

Cookery shops sell plastic 'lettuce knives' because iron and ordinary steel knives can discolour lettuce. Stainless steel knives don't. But i just tear it into pieces - saves on the washing up!
