76% of people lay claim to a healthy diet, but further investigation reveals that despite honourable intentions, Britons literally don't know what's good for them and are in a daze over healthy eating guidelines. A new health study of 2,157 Britons, marking the launch of Warburtons campaign to encourage the nation to eat more fibre, reveals that while people are aware that fibre – typically found in bread, pasta, rice, fruit, vegetables, beans and nuts – is essential for keeping their digestive healthy, more than three-quarters (76%) of men and women do not know that the guideline daily amount (GDA) of fibre is 24g, despite half of respondents believing that they eat enough fibre.
