Stephen Walsh of the UK Vegan Society challenges dubious claims made by Robert Cohen, the "NotMilk" man: http://www.vegsource.com/articles/walsh_openletter.htm (Cohen's original article is at http://www.notmilk.com/tomfoolery.html ) Cohen is not known for accuracy in science; it's good to see mainstream vegans speaking out about the abuse of science that is (sad to say) common in diet advocacy.
