Banning things period is a dumb idea. They should focus on proper nutritional education & promotion of activity.
At the end of the day however, individuals make their own choices about what they decide to put into their mouths.
If we went down the road of banning all things that were supposedly 'bad' to comsume, there would be nothing left on the planet, other than lettuce, mung beans & bean sprouts.
They need to stop all the fad diet shit & scare mongering 'the soy craze', 'the gluten free craze', 'the carb free craze', the 'eggs are bad for you', 'too much meat is bad for you', 'protein will kill you', 'soy bread will give you bitch tits' & just fckn educate themselves on food, nutrition & their own bodies. Full stop.
If you know your shit & your body, nothing is truly 'bad' for you. Life, is just about balance.
