New York city's standard-setting efforts to improve the heatlh of its citizens have provoked resistance in the past from bar owners, fastfood restaurants and global food and drink companies.

About 300 people turned out to oppose new city regulations that in effect ban school "bake sales" - an all-American fundraising staple where students and parents sell homebaked cakes and cookies to fund museum trips and equip their sports teams.
The sales, which can raise as much as $500 a time, have fallen foul of efforts by the Department of Education to improve the nutritional quality of foods available in schools as part of its battle against rising levels of childhood obesity.
