Victoria tweeted about her new eating scheme on Friday praising the recipe book by Vicki Edgson and organic chef Natasha Corrett.

While following the plan at least 70 per cent of your diet should be alkaline, while the other 30 per cent can be acidic ... which basically means a lot of fruit and vegetables.

The books authors claim that acidic foods are harder on the body, forming acidic residues in the bloodstream which puts pressure on the liver and kidneys.
