We all do it, but do we all know that flatulence is actually a warning sign of what’s going on in our bellies? Rachael’s research is joining others in showing that a diet too heavily reliant on carbohydrates causes an imbalance of microflora in our guts. Rachel is a nutritionist with an interest in how food and our environment influence, benefical or not, our wellbeing. Her talk causes you to think on what we are doing to ourselves and how we can overcome them. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx
