Sir Robin Janvrin, the Queen's private secretary, likes to compare Marmite to the royal family, saying that the former has moved with the times "but the changes have been made gradually and with respect for tradition". I'd say Marmite was moving at a faster pace: pots of limited-edition Marmite Guinness are for sale on eBay for upwards of £10. But there are similarities: just as Marmite is banned from advertising to kids by Ofcom, so are the majority of Duchy Originals products.



A new report has blamed Mother Nature for the number of obese children in the UK. According to research by analyst Weatherology, changes in weather patterns affect chemicals in our bodies. When it's a miserable day, humans have a subconscious craving for fattening foods, it says. It's not because people are greedy, lazy or like burgers, it just isn't sunny enough.



Some great PR for Cadbury came when researchers found that its Bournville Deeply Dark chocolate gives a buzz in the brain, which lasts four times as long as the feeling of a good kiss. As Prince Wills has split from the eminently kissable Kate, we wonder: instead of playing the field, maybe he will just eat chocolate.



You'd think that a supermarket job description for a vacancy on the fish counter would be short and sweet. Not so. Whole Foods Market's store in Kensington has issued a 617-word missive, including a 13-point list of duties, a 10-point list of intellectual requirements and a list of 10 physical requirements. It also lists nine other duties. Is it being thorough or just covering its arse for legal reasons?



You have to admire Tesco's business sense. It's selling Andrew Simms' book Tescopoly, which has a pop at the supermarket for choking local economies with its size and pricing strategy. As usual, though, Tesco gets the last laugh. To show it can undercut other businesses the book is being sold at a 20% discount.
