My mum is a bit of a crank. Not a health nut, she’s not consistent enough. She had/has fads that she gets over very quickly. I distinctly remember the time she got rid of all the chocolate and replaced it with carob. Luckily that was over quickly.
She also went through a longer phase of buying this range of sugar-free sweets from Boots. They came in a white wrapper with a crocodile on.
Any ailment you get is blamed on the fact you eat sugar and can be cured by taking a vitamin.
(This is the same woman who happily gave me cans of red bull to take in with lunch at school when I was 13 or so.)
