Apparently Victoria Beckham is guzzling a pint of posh vegan superfood, seaweed and algae shake per day. Yvonne Bishop-Weston says it's not as wacky as it sounds.

Yvonne Bishop-Weston Harley Street Nutritionists says you don't need Posh's bank balance to go on Victoria Beckham's seaweed and algae diet. You can get chlorella algae for as little as £7 per month and make your own sushi using nori seaweed sheets, quinoa and marinated vegetables. You can make your own nutritious shakes by adding hemp protein, hemp oil and a teaspoon of chlorella algae powder to berry smoothies. You could even make your own hemp milk with a Yaoh Hemp milk maker.
