There was a recent advertising campaign saying that McD*nald's fries were made from nothing but potatoes...

WRONG!

The chips are processes and part-fried in one country, usually in beef tallow, flown halfway round the world, soaked in dextrose often contaminated with gluten and drenched in huge amounts of salt. And that is before they get to the outlets, deepfried and drenched in salt again and left for hours under a heat lamp.

Mmm... tasty. My arteries are clogging up just thinking about it.
