A team of international scientists appear to have discovered why hot potato fries/chips are so tasty. Simply put, the brain gets ‘hijacked’ by the combination of high-fat and high-carbohydrates – making hot chips and similar food highly attractive. Scientists from Yale University wired 206 people up to brain scanners, and then showed them images of fatty, carby and so-called ‘combo’ snacks like hot fries – which are high in both carbs and fat. Every time an image of a combo snack came on the screen, the reward centres in the subjects’ brains lit up – regardless of whether they said they liked it or not. The research paper was published in the journal Cell Metabolism and re-posted by Scimex. In essence the scientists found that foods high in both fat AND carbohydrates trigger the reward centre of the brain, more so than other processed foods that may just contain one or the other.
Auckland University of Technology Professor of Public Health, Grant Schofield says these foods are rarely found in nature, so our brain has not evolved to deal with them. “You’re basically hacking the brain – providing signals that the brain was not meant to see. And it can’t deal with them.” Hot chips seems to be a “different kind of brain food.” (Sources: MSN/Scimex. Press release)
