I quit sugar a few months ago now and I constantly have people rolling their eyes at me when I refuse cake/sweets/soft drink or when I say that I don't eat refined sugar. Usually followed by comments like "there's nothing wrong with sugar" or "just once won't hurt" or "but it's a special occasion!". And when I say that I really just don't enjoy that food anymore, that it actually makes me feel ill if I eat it, I get accused of taking it all too seriously and suggestions that I have some sort of eating disorder!
The amount of negativity and peer pressure I get about it is ridiculous!
But I'm sure that when people first started coming out saying that smoking was bad for you, they probably got a similar reaction. Big food businesses are currently reacting to the anti-sugar movement in the same way that tobacco companies reacted to the anti-smoking movement!
I reckon we give it 10 years and the whole jerf (just eat real food), lchf, iqs movement will no longer be a movement - it will be mainstream.
