A new natural, calorie free sweetener - an answer to obesity?

Available for over a year

Data protection breaches should be punishable by custodial sentences, and the Information Commission's powers enlarged. These are some of the recommendations of the new Justice Committee's report on data protection and referral fees. Winifred Robinson speaks to Justice Committee with Chairman Sir Alan Beith, and Malcolm Tarling from the Association of British Insurers. York is the home of a pilot to become Britain's first dementia friendly city - we find out what this means. Stevia is the first calorie free sweetener and set to be approved for use across the EU in a few weeks. So will it answer dieters dreams of eating treats and staying slim, as well as making a lot of money ? We find out, and ask how good the science is that calorie free sweeteners do in fact help you lose weight. We also report on the government's Call to Action on Obesity - will it halt the rise in obesity by 2020 as pledged, and does it put too much emphasis on us, and too little emphasis on the food industry. We look at the new banks promising a better deal for customers - do they deliver. And what effect will anticipated changes to solar tariffs mean for green energy. Presented by Winifred Robinson.
